Definition
It is defined below to be commonly used in construction industry, and can be found in many textbooks and Internet resources.They are herein only
It provides for exemplary purposes, and is not intended to limit the disclosure.
Torque is applied to the twisting resistance of object such as wheel or crankshaft.Note that it is not that must deposit for torque motion
?.For example, even if not moving, you are also to the spiral shell if you, which stand, is attached to the lug wrench of the lug bolt of clamping stagnation at one
Bolt applies torque.For simplicity, the torque of this paper is that unit is measured and described with ft lbf foot (lbf-ft), is meaned
Be equivalent to act on length unit be foot lever end on given force (as unit of pound).For example, with 180 pounds of body
Master station generates the torque of 180 lbf-ft on the lug wrench of one foot of long moment arm.In addition, 90 pound weight
Child station applies identical result torque on two feet of long lug wrenches.
Function is applied force by certain distance.It note that unit for describing function and moment of torsion with (such as pound is multiplied by English
Ruler), but the unit of work can be write as ft-lb, to be different from torque value.Real difference between torque and function is, this
Or in the case where function, parasang (for example, " foot " part) is described mobile length (such as foot), and for torque,
Distance describes the length of moment arm.If one car has been pushed away 30 feet with 100 pounds of power, the function done is exactly
The function of 3000ft-lb.One simpler example is to promote weight (as unit of pound) to give set a distance (as unit of foot).
If you use certain mechanical advantage, such as capstan winch, then you can do same amount of function, because by subtracting required force
Half, you will have to double the distance of applied force to realize same target.
Power is application of the function in finite time.The function of 550 ft-lb is equal to one horsepower (HP) in one second.
Therefore, it is described below and calculates for explaining the conversion from torque to horsepower.It is pushed away with 87.5 pounds (power) in 1 foot of power
On the end of moment arm lug wrench, apply the torque of 87.5 lbf-ft.Because moving not yet, produced without function or power
It is raw.However, it is contemplated that lug bolt is slightly loosened and started turning, but it is to maintain spanner rotation and needs same 87.5 pounds
Power.For each turn of spanner, (this is to push to pull to the power of 87.5 pounds of the application on (1 foot of 2* π *) or 6.28 feet of distance
The hand shape of hand at plus circle circumference).Therefore, the function for generating 550 ft-lb in total carrys out rotary spanner.Only when this system reality
On border when moving, the function can just be done.From the point of view of calculating function, this is a quick step, it may be said that if function applies sufficient
It is enough fast, with one turn of rotating spanner per second, then the function per second that 550 ft-lb will be, it means that be applied with one horsepower of function
Rate.
As can be seen that HP is directly proportional to torque and RPM from definition." directly proportional " means to may relate to multiplier.It uses
Above-mentioned example number remembers that 1 turn per second is equal to 60 RPM, and the relationship between HP, torque and RPM can determine as follows:
Torque * RPM * constant=hp
87.5 60 revs/min of lbf-ft * * X=1 hp
X = 1/(60 * 87.5) = 1/5250
1/5250=hp of torque * RPM *
Hp=(torque * RPM)/5250
For internal combustion engine, torque is usually provided with certain RPM, the reason is that it cannot generate torque when engine does not rotate.
Once engine operation is sufficiently fast to maintain its own operation, so that it may measure the power applied against load, and can measure
The speed of engine rotation.Hence, it can be determined that torque (and therefore power) value.
In some embodiments, (it may include unidirectional flywheel clutch, bearing clutch to term clutch apparatus, such as
Wedge clutch (such as CSK type unilateral bearing) or other similar suitable one-way clutch devices) for describing when driven
When axis is rotated faster than drive shaft, such as when reciprocating engine slows down and crankshaft slows down, make drive shaft (i.e. according to retouching herein
The crankshaft for the reciprocating engine stated) it is detached from the device of driven shaft (output shaft of power delivery apparatus i.e. described herein), such as
It is lower described.
The problem of being found in conventional reciprocating engine design
In continuous operation, the reciprocating motion of piston is converted into the rotation of the crankshaft of load connection by crankshaft reciprocating engine
Movement.Reciprocating internal combustion (IC) engine will be released in combustion chamber (such as cylinder) using crank mechanism via combustion of fossil fuels
The explosion energy put is converted into the rotating mechanical energy for promoting object.External combustion (EC) engine, such as steam engine also use
Crank mechanism.
No matter internal combustion engine be 2 or 4 (or more) circulation and/or no matter it is gasoline-type, propane, natural gas type
Or diesel-type (or other types of fuel or thermal cycle), most of reciprocating engines all use reciprocal fortune of the crankshaft by piston
Dynamic (power) is converted into Rotational mechanical movement (power).
In brief, system and method discussed herein are intended to the output torque (power) and crankshaft of reciprocating engine
Separation, and the torque (power) is conveyed by substituting power delivery apparatus (such as dynamical system) path, which has relatively not
Become the maximum length moment arm of (such as consistent or constant), to generate the torque for being used for output shaft.
At least due to following reason, this system and method are estimated to be advantageous.
Crankshaft in typical reciprocating engine will start during the various circulations of engine as its major function
Each of one or more pistons of machine return to the previous position in each cylinder.In addition, crankshaft secondly by with
In rotating energy is conveyed to any load that engine is connected to.Crankshaft, which is efficiently performed, returns to its previous position for piston
(for example, top dead-centre), but the usual inefficiency in terms of the load that potential torque and power are transported to engine application.This
The basic change of torque moment arm length when the main reason for kind is inefficient is crankshaft rotation.Crankshaft every half-rotation, length from
Zero changes to maximum value.Accordingly, with respect to similarly sized engine of the conventional crankshaft as power output shaft is used, base is used
This constant maximum length moment arm is the power that the power output shaft of engine generates the reciprocating engine of torque and power
Conveying device is expected to generate the torque and power of bigger (for example, significant bigger).
Therefore, system and method as described herein can be used for manufacturing more energy efficient engine, can be used smaller
Component is designed and manufactured with reduced size, and still generates desired power level.In some cases, these efficiency
Improvement with power output expects also have a direct impact fuel consumption and efficiency, this can lead to the hair of more fuel-efficient
Motivation.For example, as described herein, this raising of fuel efficiency is estimated to will affect operation with constant force for automobile application
The automobile of the power delivery apparatus of moment arm possesses cost.

Specific embodiment
Fig. 1 a and 1b are shown with the reciprocating engine for fixing cylinder 102, piston 104, connecting rod 106 and crankshaft 108
100 schematic diagram.As shown, piston 104 moves down in cylinder 102 during expansion stroke, and 108 up time of crankshaft
Needle rotation.The typical expansion stroke of internal combustion engine proceeds to rotation from 0 ° of after top dead center (ATDC) of crankangle (θ)
ATDC180 ° of piston lowest position.
The vertical force (due to the combustion pressure in cylinder) that piston applies on the crankshaft of internal combustion engine can be write as:
Vertical force=Ρ(θ)Cos a A equation 1
Wherein P (θ) is combustion pressure, is the function of crankangle (θ) (relative to top dead-centre), and A is substantially hanging down for top land
Directly in the total projection surface area and a of stroke axis 110 be connecting rod angle (relative to cylinder centerline).It note that some
In engine design, connecting rod can be connected to piston via the off-axis piston pin of the center line from piston (for example, wrist pin), this
Usually influence connecting rod angle.The method that pin offset can be the stress that manufacturer is reduced on reciprocating part, because it allows
These parts are lighter, this can cause more effectively to manufacture and less power loss and higher rpm energy in engine
Power.The complementary result of pin offset can reduce piston knock, this is because from high thrust to small during power operation
The more progressive transformation of thrust.
The moment arm (or torque arm) (for example, being provided as " m " in Figure 1b) of twisting resistance is generated on crankshaft with crankshaft
It rotates and changes.Moment arm (m) is rotation axis (3) (its center for being usually located at piston and/or cylinder of main bearing journal
At line 110) and the rotation axis (2) of crank-pin axle journals between horizontal distance, at crank-pin axle journals, connecting rod is connected to crankshaft
On.Therefore, the variation length of moment arm can be write as according to the rotation position (such as crankangle θ) of crankshaft:
Moment arm=rSin θ equation 2
Wherein r be from the center line (for example, rotation axis) (3) of main bearing journal to connecting rod throwing arm or crank-pin (that is,
Connecting rod is connected to the position of crankshaft) center line (for example, rotation axis) (2) radial distance, therefore,rSin (θ) is vertical
The length of power torque moment arm.Note that the maximum length of the torque moment arm of variation present in 90 degree of crankangle, and
Equal to throw of crankshaft.
Using the definition of the component of above-mentioned various connections, the function that can be used as crank shaft angle θ writes out following equation and carrys out table
Show crank torque (twisting resistance) (T):
T(θ)=vertical force (θ)·Moment arm m(θ) equation 3
After aforesaid equation is combined, the torque that reciprocating engine generates during expansion stroke can be indicated are as follows:
T(θ)=P(θ)cosα·A·rsin(θ) equation 4
As shown, the torque equation depends critically upon crankangle (θ).Fixed engine is designed, A and r are constants,
AndαBe moment arm (i.e.rSin θ) and length of connecting rod (l) function.Length of connecting rod (l) being equal to wrist pin, (it connects connecting rod
To piston) rotation axis (1) and crank-pin the distance between rotation axis (2).Piston pressure P (θ) is also crankangle (θ)
Very strong function, and for many burning correlative factors (for example, fuel-air ratio, compression ratio, fuel type and other
Factor) it is different.The pressure P (θ) of internal combustion engine and external-burning engine is also possible to different.Piston pressure can also be with
The variation of engine speed and change, engine speed is usually indicated with revolutions per minute (RPM).
The pressure (for example, piston pressure) on top land is acted in typical internal combustion engine, in cylinder in song
Position top dead-centre (TDC) of axis reaches peak value slightly after, at about 9 ° to 18 ° of ATDC, depends on specific engine and designs,
And it can change with engine speed.For example, Fig. 2 depicts the example internal combustion engine of the function as crankangle (θ)
Example piston pressure 52 and moment arm length 54.As shown, the several years reach maximum value to piston pressure 52 after tdc, and
And it is mobile in ATDC180 ° of bottom position to it then as piston and at a good pace decay.54 function (r of moment arm length
Sin θ) start at 0 ° of tDC (because the tie point of connecting rod to crankshaft is located at main bearing journal rotation axis (such as center line)
Surface), maximum value is reached at 90 ° (because crank-pin rotation axis is generally positioned immediately in main bearing journal rotation axis
Side), and 0 ° (because surface that connecting rod returns to crankshaft axis to the tie point of crankshaft) is again moved at 180 °.
From this curve graph of Fig. 2 as can be seen that when the vertical force on piston is in maximum value, near top of stroke, for making
The moment arm of crankshaft rotation is very short.This directed varying forces moment arm influences significantly and limits the torque of generation.
Example constant length moment arm 56 is also shown in Fig. 2, if output power system has perseverance as described herein
Measured length moment arm, the length having are about the maximum length of directed varying forces moment arm in entire expansion stroke, then it can be seen that
The constant length moment arm 56.It is as follows and described, there is such constant length moment arm to generate torque (that is, special
During not being the maximum pressure in cylinder), more output torques and power can be extracted from internal combustion engine.
It, can in order to show influence of the constant length moment arm to engine output torque and horsepower relative to directed varying forces moment arm
Prediction power in the case of two kinds to calculate typical internal calculates.The first situation be directed varying forces moment arm (Moment arm=
r sinθ) and second situation be constant length moment arm (Moment arm=m)。
Directed varying forces moment arm construction with constant force moment arm construction between it is simple compared with can by using two kinds in the case of phase
Deng respective value various equations more described herein estimate.
Using example pressure curve shown in equation above 4 and Fig. 3 (be derived from Rakopoulos, C.,
Michos, C., and Giakoumis, E., Availability analysis of a syngas fueled spark
Ignition using a multi-zone combustion model, Energy, 33 volume, the 9th (2008 years 9 phase
Month), the 1378-1398 pages, its content is totally integrating herein by reference hereby), directed varying forces moment arm engine shows
Example torque value can be calculated in each crank shaft angle in entire expansion stroke.In order to simply compare torque value, several no lists are used
The value of position is standardized various parameters and size.Particularly, engine strokes (S) are 2;Piston area (A) is
3.14159;Engine bore (B) is 2;Crank throw (r=S/2) is 1;Length of connecting rod (L) is 2.924, and all these values are used for
Simplify and calculates.The result of these example calculations is shown in the table on fig. 4.As indicated, discovery is typical using these example values
Internal combustion engine generate about 0.122076 average torque.
For the internal combustion engine of the moment arm of constant length, as described above, torque equation can simplify for T (θ) =P
(θ) Am, wherein P (θ) it be cylinder pressure (for example, as depicted in fig. 3) and m based on crankangle is constant force moment arm
Length (for example, moment arm (m)=moment arm radius (r)=S/2).Similar to being discussed above with directed varying forces moment arms
Typical internal can be used modular size same as above and calculate in entire expansion stroke in various crank shaft angles
Estimated torque value.The result of these example calculations is shown in the table of Fig. 5.As indicated, using these example values,
The internal combustion engine for being found to have the theoretical modification of constant force moment arm generates about 0.290584 average torque.Therefore, have
The average output of the internal combustion engine of constant force moment arm is the big of the average output of the internal combustion engine of typical directed varying forces moment arm
About 2.38 times.
Additional calculating is also completed, the power and torsional performance of the raising of constant force moment arm internal combustion engine are had estimated.
For illustration purpose, (for example, directed varying forces moment arm situation and constant force moment arm situation) is interior for what is calculated in both cases
Burn engine is dual overhead cam (DOHC), 16 valves, 4 recycle gasoline engines.For the pre- measurement of power in the case of calculating two kinds
The predetermined cylinder pressure curve (as shown in Figure 6) of several different engine loads is taken and has been used in rate and torque output, so as to
Compare directed varying forces moment arm and constant force moment arm structure using the calculating for being similar to the calculating of torque meter for being used to prepare Fig. 4 and Fig. 5
It makes.The pressure curve of Fig. 6 is derived from Marty chenko, A., Park, J., Ko, Y., Balin, A., et al. A
Study on the Possibility of Estimation of In-Cylinder Pressure by Means of
Measurement of Spark Gap Breakdown Voltage, SAE Technical Paper 1999-01-1115
(1999), content is totally integrating herein by reference.As being described in detail in the document of Martychenko et al.,
For typical DOHC, 16 valves, 4 cylinder gas engines, pressure curve is exemplary, and therefore, uses 3.1693 inches of work
Consent diameter (B) and 3.1693 inches of piston stroke (S) are estimated to calculate torque for preparing different engine loads and power
The calculating of evaluation, this be the DOHC being described in detail in the document of Martychenko et al., 16 valves, 4 cylinder gas engine types allusion quotation
Type example.(for example, 4 cylinder, 2300 cc OHC Hyundai Sonata engine).For setting engine load (for example,
59 lbf-ft), in engine speed range (that is, speed of crankshaft), go back calculated torque and power output estimated value.
Moment arm (m)=throw of crankshaft (r)=1/2 stroke (S/2) in this case, constant most greatly enhanced to determine
The power output of moment arm engine is spent, the reciprocating motion of piston is converted into the rotary motion of output shaft.It is depicted in Figure 15
An adoptable exemplary universal (for example, embodiment).Each rotation for crankshaft, during the rotation, even
Bar is to crankshaft tie point (2) (for example, crank-pin) traveling π * S, since piston moves down the distance of stroke S and returns up
The distance of stroke S, so output shaft interface (5) is (that is, piston is connected to by pull rod, tensioning apparatus or similar component
The point of clutch apparatus (and being therefore also connected to output shaft)) only move 2*S.Although for simplicity, the example of this paper
It is described generally as only one cylinder, but it is to be understood that, the exemplary engine with more than one cylinder will lead to output
Axis is persistently rotated as each in different pistons travels downwardly, to generate the movement of output shaft.Therefore, the revolving speed of output shaft
Proportionally it is lower than the revolving speed of crankshaft.Therefore, for the steady-state speed of the output shaft of the determining consistent revolving speed for crankshaft, crankshaft
Revolving speed multiplied by (2/ π).It note that piston is in top of stroke (at top dead-centre (TDC)) and stroke bottom during crankshaft rotation
(at bottom dead centre (BDC)) instantaneously stops movement in the vertical direction, and as crankshaft rotates, piston is at top dead-centre (TDC)
Quickly accelerate and slow down between bottom dead centre (BDC).Therefore, the estimating speed of output shaft can be equal to (that is, by moment arm length
(for example, distance that the position of clutch apparatus is connected to from the center of output shaft to pull rod, tensioning apparatus or like)
Influence) piston since the 0 of TDC, when accelerating to maximum speed and then decelerating to the 0 of BDC piston average speed.Such as
Upper described, when piston is moved upwards up to TDC from BDC, output shaft can usually continue to rotate.Therefore, when piston moves up
When (along and the rotation of output shaft opposite direction), output shaft for example can be used piston and travel up to TDC from BDC
When average speed continue to rotate come the speed estimated.That is, when piston can be transported back and forth in two opposite directions
When dynamic, absolute average speed when the speed of output shaft can be moved between BDC and TDC based on piston is estimated.
In addition, in the engine only with a cylinder, it is contemplated that, when piston moves up (that is, and
The movement of piston does not directly apply rotary force to output shaft), the device of such as flywheel gear can be used for keeping output shaft
A part of revolving speed.
It is shown in these curve graphs of result calculated in figs. 7-14.As shown, for constant maximum length torque
The torque and power for the estimation that arm engine is observed increase usually proportionally bigger for all calculated values.As described above,
The revolving speed of output shaft and crankshaft is not usually identical, and the revolving speed (for example, 2400 RPM) listed in Fig. 7-14 is turning for crankshaft
Fast (that is, the revolving speed for being not necessarily output shaft).
Other than the potential increase of above-mentioned torque and power, it is contemplated that described herein that there is constant maximum length moment arm
Power delivery apparatus can also be used for storage energy (such as power), stored energy will be used when engine retard.Example
Such as, as described in detail herein, power delivery apparatus may include be connected to by clutch apparatus (such as one-way clutch) it is past
The output shaft of compound engine (that is, reciprocating piston of engine), the clutch apparatus allow output shaft in one direction
It rotates freely.That is, clutch apparatus can only engage output shaft when piston moves downward.As described above, this construction
Output shaft is helped allowed to be different from the speed rotation of the crankshaft of reciprocating engine, power delivery apparatus is connected to reciprocating
The crankshaft of engine.
In some respects, with the ability for being different from the speed rotating output shaft of crankshaft power delivery apparatus is used as
Power storage device.For example, during use, user can reduce the revolving speed (for example, due to engine retard) of crankshaft, this
Normally resulting in the power based on reduced revolving speed reduces.However, since output shaft usually can be relative to crankshaft along a side
To rotating freely, so output shaft does not need to slow down when crankshaft deceleration.Therefore, when crankshaft deceleration, such as when user exists
When making engine retard during use, it can permit output shaft with higher revolving speed and continue rotation to continue to generate power.It is as follows
Described, output shaft may include flywheel, which helps to create and keep spinning momentum and the movement of output shaft.
In some cases, this construction can be used in order to store or recover energy during engine retard.Example
Such as, it is used in some embodiments in automobile in reciprocating engine and power delivery apparatus, during crankshaft deceleration (for example,

In addition, in some embodiments, output shaft may be coupled to the connector or component (such as speed change of automatic transmission
The torque-converters of device) so that output shaft continue and consistent rotation (for example, after crankshaft slows down suddenly) can contribute to
Automatic transmission provides consistent revolving speed and power.As described above, this connector (for example, torque-converters) can also be used for reducing it is defeated
The influence of the pulsating motion of shaft, pulsating motion can be caused by the reciprocating motion of the piston of driving clutch apparatus.
Reciprocating engine with constant force moment arm
As described above, theoretically can be by using rotary power system (such as power delivery apparatus) from the acting of reciprocating piston
More (for example, significant more) spin dynamics power are extracted in stroke, rotary power system is connected to past via torque moment arm
Dual Piston, length of the torque moment arm in entire expansion stroke with almost the same (for example, constant) is (for example, constant
Maximum length).In some embodiments, the torque moment arm of almost the same length may include torque moment arm, the torque
Moment arm is fixed on setting length, which is its maximum length, and allows to omit only with respect to fixed maximum value
Change (for example, constant constant or consistent).In some cases, due to contact area along handover gear move or
It is moved between the sprocket wheel and chain of handover, the moment arm of almost the same length can change (for example, slight variation).
For example, example reciprocating engine 100 has reciprocating motion element (for example, piston 104) and valve with reference to Figure 15
(for example, intake valve and exhaust valve) 105, the reciprocating motion element are connected to rotatable crankshaft 108 via connecting rod 106, and by
It is configured to the upper and lower translation in cylinder 102, valve (for example, intake valve and exhaust valve) 105 controls gas and enters and leaves cylinder
102.Engine 100 may be coupled to power delivery apparatus 200, which has individual power output member
Part (for example, power output shaft 202), the power output element is via the power delivery apparatus with constant length moment arm 204
200 are rotationally coupled to piston 104.Power output shaft 202 can be connected to any in the various devices using rotary power
One kind, including automotive transmission is (for example, be used for car, truck, motorcycle, Architectural Equipment (for example, bull-dozer) or other transports
The power train of device, such as aircraft or ship), generator, electric welding machine or using rotary power other devices.
As shown, power delivery apparatus 200 may include being connected to the elongated translation tensioning apparatus of piston 104 (for example, drawing
Bar) 206, so that as piston 104 moves back and forth in cylinder (for example, when cylinder is vertically-oriented, such as the example institute of Figure 15
Show, move up and down), pull rod 206 with 104 substantially similar way of piston it is mobile (for example, the traveling essentially identical with piston away from
From, speed, acceleration, and generate essentially identical available axial force (for example, the power that can be used for doing external work)).Pull rod 206 can be with
Any desired position being connected on piston 104.That is, pull rod can be fixed to a region of piston, or connection
To wrist pin, wrist pin connects the piston to connecting rod.Pull rod 206 is usually configured to be attached to power delivery apparatus 200
Power output shaft 202 or the other components being integrated in power output shaft 202 handover.For example, in some examples as described below
In, pull rod 206 may include the rack gear slender member of a row or multi-row gear teeth (for example, with), the rack gear be configured to
The handover of rotating parts 208 and engagement (5), all power delivery apparatus in this way of the rotating parts 208 are connected to output shaft 202
Roughly circular component (for example, geared system).The restriction opening 210(pull rod 206 of engine passes through opening 210(for example, drawing
Bar opening) enter cylinder (such as cylinder head)) part generally include sealing device, pass through opening to limit (such as preventing)
The air-flow and the pressure loss in the region between pull rod.
Although the linear movement of piston to be transformed into the power delivery apparatus usually quilt of the rotary motion of power delivery apparatus
It is described and illustrated as the single rack gear for joining and engaging with the geared system for being connected to output shaft, but other constructions are also possible
's.For example, in some embodiments, power delivery apparatus may include one or more additional gear groups, for based on reciprocating
The linear velocity and Li Lai of piston increased or decrease the revolving speed or torque of output shaft.Additionally or alternatively, power delivery apparatus can
To include any one of various device or systems, the linear movement of piston can be suitably transformed into the rotation of output shaft
Transhipment is dynamic, while keeping the moment arm of almost the same (for example, constant) length.For example, in some embodiments, power conveying dress
Set (for example, rotating parts of power delivery apparatus) can additionally or alternatively include belt system, pulley system and/or
Chain drive system.In some cases, with reference to Figure 16-18, tensioning apparatus (for example, belt, cable 206a, chain 206b or
Other devices of tension can be applied) one end can be attached to piston, and pulley can be used in the other end of tensioning apparatus
208a or sprocket wheel 208b are connected to output shaft.It can also include spring return mechanism 212, to be moved to stroke top in piston 104
Tensioning apparatus (for example, cable 206a, belt or chain 206b) is helped to return up when portion.In some embodiments, power is defeated
Sending device may include any one of other types of system of power transmission, including various devices.
Since the movement of piston 104 replaces back and forth, but it is generally desirable to only rotating output shaft 202 in one direction, institutes
It is usually configured to substantially with power delivery apparatus 200 (for example, rotating parts 208 in some cases) at one
Output shaft is engaged on direction (for example, for Two-way Cycle internal combustion engine, only during expansion stroke, when piston is due in cylinder
Pressure increase caused by burning and when moving down), so that output shaft only rotates in one direction.Note: for four circulations
Engine, clutch bearing power delivery apparatus will engage in air inlet downward stroke and acting downward stroke, but can still only
Permission rotates on a consistent direction.
In some embodiments, power delivery apparatus (for example, rotating parts of power delivery apparatus) is configured only to
Output shaft is clamped when tensioning apparatus (for example, pull rod, cable or sprocket wheel) is pulled in cylinder by piston, and then when with work
Plug returns to top dead-centre, when pull rod removes cylinder, substantially discharges output shaft.In some embodiments, power delivery apparatus 200
Including clutch apparatus 214, such as one-way clutch, it is configured only to just engage when tensioning apparatus is moved in cylinder defeated
Shaft and output shaft is rotated, but when pull rod removes cylinder, allows the rotary part of power delivery apparatus (for example, round
Geared system) it is rotated freely in the opposite direction relative to output shaft, with limitation (for example, preventing) as reciprocating piston is in gas
It is moved in cylinder, output shaft unintentionally alternately rotates in a manner of back and forth.In some embodiments, rotating parts may include chain
Wheel, gear, pulley, wheel, clutch apparatus or one or more device it is any appropriately combined.
In some instances, as further discussed below, clutch apparatus 214 includes unidirectional flywheel clutch, bearing
Clutch, such as wedge clutch (for example, CSK type unilateral bearing) or other similar suitable one-way clutch devices.Clutch
Device bearing can play the role of simple ball or roller bearing when rotating in one direction, and revolve in the opposite direction
(for example, preventing) rotation is limited when turning.What this was sometimes realized by using spring-loaded voussoir, spring-loaded voussoir
Serve as the voussoir between two bearing races.Clutch bearing is variously referred to as CSK bearing, unilateral bearing, one direction bearing
And wedge bearing.One-way clutch device can be it is spring-loaded, to limit gap when output shaft is engaged.Alternatively or
Additionally, clutch apparatus may include ratchet mechanism, such as pawl clutch, make output shaft defeated substantially only in power
Device is sent just to engage when attempting rotating output shaft in one direction.
As shown, since the handover between pull rod and power delivery apparatus is remote relative to the axis of movement of reciprocating piston
With a distance from rotation axis from output shaft is substantially uniform (that is, being different from the connection between connecting rod and crankshaft, as described above), so
Generate moment arm substantially constant, the stabilization or constant of the power for acting on the torque on output shaft.
As described above, compared with script extracts the possible situation of power from crankshaft, it is this almost the same (for example, substantially permanent
It is fixed) length moment arm allows increased (for example, dramatically increasing) torque of output shaft drive via pull rod extraction and power defeated
Out.
Since the substantially invariable moment arm of the torque formed from reciprocating engine extracts, it is contemplated that engine will be easier
Mechanical rotation movement is converted by the explosion energy of burning, and engine heat loss will reduce and the overall thermal of engine
Efficiency will improve.
Although conventional engine shown in usually still includes crankshaft-and-connecting-rod, they are at least used to rush in acting
Make piston back toward top dead center after journey, but it is contemplated that in some cases, the size and structural intergrity of crankshaft-and-connecting-rod are all
It can reduce, the reason is that these components are no longer used to shift available torque and power from engine.It is anticipated that crankshaft and company
This reduction of bar size helps to reduce parasitic power loss amount, and parasitic power loss originally may be by additional in engine
Gyrating mass causes.
Example reciprocating engine shown in the schematic diagram of Figure 15 can be with appointing in various suitable constructions and design
What one kind is realized.As described above, engine (such as internal combustion engine) can be specifically designed as including that individual power is defeated
Device and power output shaft are sent, the power of reciprocating piston generation can be extracted by the power output shaft.It is this to be specifically designed
Engine may include reduced crankshaft-and-connecting-rod, to limit the power loss as caused by gyrating mass.
Example embodiment
In some embodiments, available engine (for example, existing internal combustion engine) can be modified to include individual power
Conveying device and power output shaft can extract the power of reciprocating piston generation by the power output shaft.For example, Figure 19-
23 show the four cylinder engine 300 of modification, are modified to include individual power delivery apparatus 400 and power output shaft
402.It note that for the sake of clarity, other parts of crankshaft, connecting rod, several seals and engine be omitted in figure.
As shown, the internal combustion engine of modification is double top-type cam (DOHC) four cylinder four circulation in-line arrangement petrol powers
Engine (for example, improved Toyota 3RZ-FE type petrol engine).For multi-cylinder reciprocating engine (such as internal combustion hair
Motivation), it is usually desirable to there is single power output shaft, therefore simple estimated construction includes the structure that piston and cylinder are in alignment with each other
It makes, so that the power delivery apparatus of each piston and cylinder can be structured as single power output shaft.Four cycle internal combustions are sent out
Motivation, every two turns of crankshaft just once expansion stroke.Therefore, for four cylinders, four cycle internal combustion engine, the every rotation 180 degree of crankshaft
It will once expansion stroke.For six cylinder internal combustion engines, every 120 degree of the rotation of crankshaft just once expansion stroke and right
In eight cylinder internal combustion engines, it is often rotated by 90 ° just once expansion stroke.The single power of above-mentioned in-line arrangement internal combustion engine is defeated
Shaft, either 4 cylinders, 6 cylinders or 8 cylinders are all desirable.Although being somebody's turn to do it may be desirable to having single power output shaft
The benefiting of the increases torque of constant-torque arm invention and power be suitable for all power cycles and all mechanical realizations (such as
V6, V8, V2, radial direction etc.) reciprocating engine.In the mechanical realization of the multicylinder engine of non-" in-line arrangement ", may have more
A power output shaft.In addition, in some embodiments, it is defeated that V-type engine construction can be connected to the power with single output shaft
Send device.That is, even if being connected to of piston in the case where the piston of engine and cylinder are not exclusively aligned each other
Tight device also can be used any one of various gear assemblies or pulley structure and be connected to public output shaft, to cause
The consistent rotation of output shaft.
In DOHC in-line arrangement internal combustion engine, the region above piston and cylinder centerline is not more or less by various hairs

It is connected to piston (for example, via existing piston pin for piston to be connected to connecting rod).In the example shown, using two
Pull rod 406 (for example, each one on each opposite side of piston), so as to the load on dummy piston 304, and can be with
Reduce the load being applied on each pull rod 406.In the design of some internal combustion engines, connecting rod is slightly off-axis with piston centreline
Ground is connected to piston.Pull rod 406 pass through engine components (such as cylinder head 302) on opening 410 be arranged, and be configured to
The opening that moves across of piston 410 move up and down.It note that four cylinder of example, four circulation reciprocating type shown in Figure 19-22 is sent out
In motivation, two in piston can be configured to move in same direction always, be separated by just 180 with other two piston
Degree.When a cylinder is lighted a fire in expansion stroke, driving piston is downwardly into cylinder, all four pull rods of two pistons
The driving load of expansion stroke will be shared by moving together.
In some embodiments, pull rod 406 includes toothed rack gear 407, and rack gear 407 is connected to the upper area of pull rod.
In some embodiments, rack gear 407 can be connected to pull rod 406, allow rack gear 407 slightly along pull rod and independently of drawing
Bar is mobile.In some cases, as shown, one or more spring elements (for example, disk spring) can be used in rack gear
409 are attached to pull rod, this can contribute to execute several functions.For example, the energy that spring can be used as power delivery apparatus is deposited
Storage device 409.As described above and as shown in Fig. 2, the pressure (and therefore also act on power) on piston in cylinder usually
There is apparent surge very early during expansion stroke, and is traveled into cylinder and rapid decay then as piston.Cause
This as shown in figs. 19-21 can compress the spring that rack gear is connected to pull rod, and a part when being increased sharply with absorption pressure is initial
Load (this will lead to pull rod and moves slightly downward relative to rack gear), thus the storage energy in spring-compressed.Then, with work
Plug is moved in cylinder and decline of pressure, and spring is unfolded to force rack gear to be resisted against on pull rod back down, to discharge
The energy of storage.This compression and expansion of spring can contribute to dispensing piston seen power near top dead-centre and increase sharply.As
Sign property, it is slightly smooth that this may be used to pressure curve, and distributes some power in entire piston expansion stroke.Additionally or
Alternatively, spring also can contribute to issuable vibration when limitation reciprocating piston translates back and forth.
Alternatively, rack gear can be permanently attached to pull rod (for example, drawing via fastener or by being formed on
In bar).The engagement rotating member that is dimensioned and configured to of rack gear is connected in parallel to rotating member (for example, generally circular tooth
408), which is connected to output shaft 402 to rotate output shaft to wheel.As described above, gear 408 is usually using clutch
Device (such as one-way clutch bearing 414) is connected to output shaft 402, so that the reciprocating linear motion of pull rod to be transformed into substantially
Only unidirectional rotary motion.
As shown, in some embodiments, output shaft is connected to using mounting device (such as bearing bracket 416) to be started
Machine (such as cylinder head), mounting device positioning output shaft, but the torque backspin for allowing output shaft to generate in power delivery apparatus
Turn.
With specific reference to Figure 20-23, cylinder head 302 includes containment member (for example, sealing element, such as labyrinth)
412, can limit and opening 410 is passed through by opening 410(pull rod 406 advance) the pressure loss, while providing enough skies

The internal diameter of seal disc 21 can be configured to just slightly larger than pull rod diameter.The internal diameter of disk spacer 22 can be than sealing
Several times of clearance distance between the big pull rod of the internal diameter of disk 21 and seal disc internal diameter, to form chamber between seal disc.Seal disc
A series of chamber of generations between 21 can produce very big gas-flow resistance, wherein forming more chambers will increase gas-flow resistance.Disk
Spacer 22 can be made into the slightly submissive trend to fluff with compensation sealing part.It is alternatively possible to by individual pliable member (example
Such as spring) it is added in stacking.
Although having been described and some example power conveying mechanisms, other examples device being shown in the attached drawings
It can be used for for the reciprocating motion of piston being converted into the rotary motion of output shaft.It in some cases, can will be described herein

Frame 1102 can also include opening (for example, hole) 1106, and output shaft 1302 can pass through the opening and be arranged.When
For frame as the movement of reciprocating piston on y-axis direction when vibrating, opening 1106 can provide gap for axis 1302.Frame
1102 mode can be connected to reciprocating piston any one of in various ways.For example, referring briefly to Figure 29, frame may include
One or more attachment points (for example, threaded hole) 1107, tensioning member is attached in attachment point 1107 with driver framework.?
In some embodiments, as depicted in figures, frame can have two attachment points 1107 balanced on 1102 two sides of frame.Due to
The attachment point of balance, the power that reciprocating piston applies can be evenly applied to frame.
Frame 1102 can be made of any material in suitable material in various structures.For example, frame 1102 can be by
Material light-weight, that intensity is high is made, such as aluminium (such as alloy;4032,7055,6061,7068,5052,2024,2618),
Titanium (such as alloy;Ti-6242), steel (such as ASM alloy;6516,6414,6419,6512,6425,6532,5844), magnesium (example
Such as ASM alloy;4429,4425).X-axis component 1130 can be made of any material in suitable material in various structures.
For example, x-axis component 1130 can be made of the high material of light-weight, intensity, such as aluminium (such as alloy;4032,7055,
6061,7068,5052,2024,2618), titanium (such as alloy;Ti-6242), steel (such as ASM alloy;6516,6414,6419,
6512,6425,6532,5844), magnesium (such as ASM alloy;4429,4425).
The x-axis component 1130 (being also shown in FIG. 30) of oscillation component 1100 is configured to as frame is along y-axis
It moves and is moved together with frame 1102.That is, the direction of motion relative to piston, x-axis component 1130 is connected to frame
Frame 1102.However, x-axis component 1130 may be constructed such that relative to frame 1102 along the x for being approximately perpendicular to piston motion
Axis is mobile.For example, x-axis component 1130 may include one or more slidingsurfaces 1133, the slidingsurface 1133 is by structure
It causes to cooperate and be sliding engaged with one or more slidingsurfaces 1108 of frame 1102.Help allowed x-axis component
1130 slidingsurfaces 1133,1108 mobile relative to frame 1102 may be substantially perpendicular to slidingsurface 1104,1020, slide

The mobile slidingsurface 1104,1020 of pedestal 1010 can be substantially along y-axis (usually in line with the movement of piston)
Setting, the y-axis may be substantially perpendicular to slidingsurface 1133,1108, and slidingsurface 1133,1108 helps allowed x-axis
Line component 1130 is mobile relative to frame 1102, and frame 1102 can be arranged along x-axis.Since complementary slidingsurface helps
It is moved in the direction y (axial direction) and the direction x (lateral) in permission x-axis component 1130, therefore x-axis component 1130 can be such as
(for example, moving along generally circular path) is rotated around output shaft 1302.In addition, slidingsurface 1133 and 1108 can be single
Solely or together limitation x-axis component 1130 is slided along z-axis line direction or is moved in other ways.
Slidingsurface form can carry out design and implementation any one of in a variety of manners.For example, slidingsurface can limit
Allocate face and/or surface.Slidingsurface, which can also limit, to be helped not being in a desired direction opposite between limiting component
Motion characteristics.That is, in some cases, slidingsurface can permit relative motion in the x and y direction, still
The relative motion along z-axis line (for example, the direction z) is limited, to help to keep driving mechanism to assemble and one during use
It rises.For example, complementary slide surface may include protrusion (for example, flange) on a component and be configured to along another component
Receive the recess portion (for example, groove) of flange.In some cases, flange and groove can be set in an x or y direction, and limit z
Relative motion on direction.In some embodiments, slidingsurface may include removable and/or interchangeable surface, such as roll
Pearl bearing or rolling bearing sliding part (for example, business line style supporting surface, such as Schneeberger type M/V).Such as this field
It will be understood by the skilled person that lubricating the surface of all slidingsurfaces and bearing and gear assembly contact, including metal pair
Metal surface, for promoting, smooth, low friction is mobile and damage, adherency, scratch and vibration is prevented to be important.This includes logical
It crosses pumping lubricant and forced feed lubrication (such as oiling) is carried out to all slidingsurfaces, or by the way that lubricant (such as grease) is close
The system lubrication of the sealing in the slide contact zone of moving parts is sealed, or by applying non-adhering surfaces coating (such as
Teflon)。
It can be used on output shaft 1302 assigning by the circular motion that the reciprocating motion of piston is applied on x-axis component 1130
Give circle (for example, rotation) movement.As a result, driving mechanism 1000 by purely axial movement (for example, along the direction y, with piston motion at
One straight line) it is converted into the movement with x durection component and y durection component, to promote output shaft with continuous tangential force.Namely
It says, when x-axis component 1130 is advanced around output shaft, the power of output shaft is driven consistently can tangentially to apply, and exist with piston
Position between top dead-centre and bottom dead centre is unrelated.For example, x-axis component 1130 may include external engagement device (for example, annular
Power transfer ring gear) 1132, external engagement device 1132 is configured to the adapting device with rotating output shaft component 1300
(such as, being connected to the rotary pinion 1304 of output shaft 1302) handover.As x-axis component 1130 around pinion gear 1304
Consistent circular motion as a result, x-axis component 1130 its along the different directions of x-axis and y-axis advance when, with consistent power
Moment arm length applies torsional forces to pinion gear.
External engagement device 1132 couples (for example, fixed) usually relative to x-axis component 1130.External engagement device
1132 can be used fastener, adhesive or mechanical connection (such as welding) any one of in various ways mode (including
Press-fit is heat-shrinked connection) it is connected to x-axis component 1130.In some cases, external engagement device 1132 and x-axis portion
Part 1130 can be manufactured into unitary members, which has machining or casting or directly formed in other ways
To the feature (for example, gear teeth of handover groove) in x-axis component 1130.
Pinion gear 1304 and external engagement device 1132 can be based on the sides for the engine that driving mechanism is used therewith
Face determines size and construction.For example, the diameter (for example, pitch diameter in the case where ring gear) of external engagement device 1132 can
To be twice of engine strokes length.Twice that external engagement device is formed as length of stroke can permit oscillation component
1100 along y-axis advance with piston advance during stroke at a distance from identical distance.Pinion gear 1304 diameter (for example,
Pitch diameter) usually it is substantially equal to the piston stroke length of engine.As a result, the oscillation of driving mechanism can be with the reciprocating motion of piston
More coordinate.When pinion gear is moved to bottom dead centre from top dead-centre and returns and is complete one turn mobile, the pinion gear that so constructs
1304 and the diameter of ring gear 1132 allow x-axis component to rotate around one complete 360 degree of pinion gear 1304.
Driving mechanism 1000 may also include idle pulley (for example, engagement) component 1200, and idler sheave assemblies 1200 can provide power to protect
Hold external engagement device 1132 with pinion gear 1304 is consistent contacts.For example, idler sheave assemblies 1200 can be with applied force, so that in work
In the entire stroke of plug, the gear teeth of external engagement device 1132 and the gear teeth secure engagement of pinion gear 1304.In some realities
It applies in example, idler sheave assemblies 1200 can be inclined in a z-direction relative to driving external engagement device 1132 and driven pinion 1304
It moves, and may include the joint element that rotates for being connected to x-axis component 1130 or being formed in x-axis component 1130
(for example, setting element (for example, column, roller, pulley, sprocket wheel or gear) 1202.That is, idler sheave assemblies 1200 can position
In on the opposite side different from external engagement device 1132 of x-axis component 1130.Setting element 1202 can be connected to pedestal
1010 joint element is (for example, fixed engagement component is (for example, complementary characteristic is (for example, column, roller, pulley, belt, sprocket wheel, chain
Item, gear or the joint element that rotates are engageable in feature wherein, such as groove or recess portion)) 1204 handover.Setting element

Power compared with torque relationship, the power and torque relationship of driving mechanism 1000 are shown in Figure 34, Figure 35, Figure 36 and Figure 37, and
It is discussed below.
Figure 34 shows the relationship between the force vector on the gear of exemplary mechanism 1000, force vector by various gears section

The pitch diameter 1504 of diameter 1502 and complementary characteristic 1204) it indicates.In example driving mechanism 1000, pitch diameter 1501 and 1502 is substantially
It is fixed with mutual relationship, so that the movement of a pitch diameter will correspond to the movement of another pitch diameter, and is applied to a section
The power of diameter is by the power for being applied to another pitch diameter (for example, ring gear 1132 and setting element 1202 are moved as a unit
It is dynamic).In addition, pitch diameter 1503 and 1504 is fixed in x-y coordinate, and is not translated in example driving mechanism 1000.Permit

About 0% to about 10%, about 0% to about 5%, about 0% to about 2%, about 0% to about 1%, about 0% to about 0.5%, about 0% to about 0.1%, about 0% to
About 0.001%), and it will realize and find to improve.
