Abstract
A vane pump type IC engine is disclosed, which is different from 3 existing ones in such areas that it has no crankshaft-connecting rod mechanism and air distributing mechanism and its parts are circular. Its advantages are simple structure, small size, and large volume displacement.
Description
Internal-combustion engine is commonly called as " motor ", and its technology belongs to mechanical engineering field.Motor is the power source of machineries such as automobile, aircraft, steamer, often is called " heart " of machinery by people, and motor plays a part the most important thing in machinery.Finned pump type internal combustion engine is the stroke piston combustion engine (as Fig. 4) that continues, triangular-piston rotor formula internal-combustion engine (as Fig. 5) and the wheeled internal-combustion engine of combustion gas (as Fig. 6) afterwards, internal combustion engine newly developed.
One, principle
(1), the working principle of finned pump type internal combustion engine
Finned pump type internal combustion engine is a kind of new work engine that the Der Grundsatz der Maschinen (as Fig. 7) according to vane pump is designed.As shown in Figure 1, piston (1) is connected as a single entity with rotating shaft (4), has the blade groove of six five equilibriums on the piston, and sealing blade (7) is contained in the groove and piston (1) together turns round and make fore and aft motion in groove.The same cylinder sleeve of cylinder body (5) (2) is integrated, and two ends link to each other with the end cap location that has eccentric pivot hole, finish longitudinal sealing (referring to Fig. 3), and the eccentric opening of end cap is the bearing bearing hole of rotating shaft (4).Its working principle is as follows:
As shown in Figure 2, (as figure a), expand to the clockwise direction rotation, and when A arm elongation＞B arm, the A arm produces thrust, promotes piston to clockwise direction rotation acting by the igniting of AB chamber in the upper end ignition timing for AB chamber pressing chamber.After 120 ° of AB chamber rotations, exhaust port is opened, AB chamber waste discharge gas (as figure b), and BC has done work in the chamber and has produced bigger thrust at this moment, and the ignition timing of expanding is just being located in the CD chamber, and this internal-combustion engine is the continuous doing work rotary engine.The waste gas in AB chamber rotates 150 ° to clockwise direction after relief opening is discharged decompression with velocity of sound, air inlet open (as figure c), and the supercharging gas of suction port (supplies the 0.12-0.2N/mm of coming by air supply system
2Fresh air) seize A arm space behind rapidly, and sweep waste gas to relief opening, this moment BC chamber thrust maximum, done work and produced certain thrust in the CD chamber.AB chamber Rotate 180 °, behind the B closure arm relief opening, the AB chamber begins fuel feeding (as figure d), and the supercharging fresh air that suction port comes continues to enter the AB chamber.Pressure in the AB chamber can be greater than 0.2N/mm at this moment
2, utilize the method for the engine electric-controlled fuel feeding of modern gasoline, can guarantee AB chamber fuel feeding, at this moment relief opening is closed fully by the B arm, can avoid the loss of inflammable mixture.Behind B closure arm air supply opening, the AB chamber enters compression work, and the AB chamber is got back to the fired state of doing work for the second time again after 360 ° of smooth pin rotations.So repeatedly, running acting continuously.
Finned pump type internal combustion engine is continuously the motor of running acting, after its outburst starting, the internal-combustion engine of six pressing chambers is arranged, and has two pressing chambers all the time at least at ignition-powering.Finned pump type internal combustion engine according to theory analysis: a 2-3 pressing chamber is the discontinuous power engine of doing; 4 and 4 finned pump type internal combustion engines with upper compression chamber are the continuous doing work motor; Piston is big more, and pressing chamber quantity can be many more, and super-huge finned pump type internal combustion engine pressing chamber can reach more than 30.
(2), the demonstration of finned pump type internal combustion engine working principle
The manufacturing technology of finned pump type internal combustion engine if stand in the domestic eighties of internal-combustion engine technology level in the past, does not only manufacture, and all is difficult to set up with regard to its principle.Because utilize fuel combustion to produce the internal-combustion engine of " thermal expansion acting " principle design in the past, must produce degree of vacuum (negative pressure) in the cylinder, fresh air and gasoline just can be inhaled in the cylinder (as Fig. 8).If there is not negative pressure, motor just can't be finished fuel feeding and air feed.The air feed of finned pump type internal combustion engine, fuel feeding principle are the new work engines of utilizing modern gasoline motor (top is automatically controlled fuel feeding, supercharge) principle and modern diesel engines (top is automatically controlled fuel feeding, supercharge) principle design to design.(as Fig. 6) is quite similar for its air supply system and gas-turbine engine, but the wheeled internal-combustion engine of combustion gas is high temperature, high pressure, utilizes the motor of " isobaric Heating Cyclic " principle acting, and its suction pressure needs very big.The supply gas pressure of finned pump type internal combustion engine is generally 0.12-0.2N/mm
2, just can realize that with the helical fan blade not only the supercharge system than the wheeled internal-combustion engine of combustion gas is simple for this, just compares with present conventional engine exhaust-gas turbocharging system, and is much also simple.
Finned pump type internal combustion engine is compared with conventional reciprocating piston type two stroke diesel engine.As shown in Figure 9, band scavenging pump two stroke diesel engine, it also is to lean on the supercharge exhaust, but its confession scavenging time is short, and porting can not be done too much.And finned pump type internal combustion engine is 90 ° for exhaust angle correspondence " bent axle " corner; Exhaust, scavenging, air inlet are in one line, and every chamber all will be through 60 ° exhaust corner, 30 ° scavenging corner and 60 ° air feed corner, and overlapping intake and exhaust corner is very big; The porting of finned pump type internal combustion engine does not have valve, and porting is all opened on cylinder body side face length direction, can do greatlyyer, can guarantee the abundant intake and exhaust of finned pump type internal combustion engine.
Finned pump type internal combustion engine is compared with conventional reciprocating piston type two-stroke gasoline motor.As shown in figure 10, this two-cycle engine porting is opened on the same corner of bent axle, and supply gas pressure is little again, and the porting size is also restricted, does not sweep the waste gas function, the acting but it can turn round equally.Finned pump type internal combustion engine has comparatively ideal exhaust, scavenging, air inlet, oil supply function; Gas handling system is not installed closure, and porting can be done greatlyyer again.So, guarantee that finned pump type internal combustion engine exhaust, air inlet, fuel feeding are no problem.In addition, two-stroke gasoline engine can not be avoided the loss of inflammable mixture, and finned pump type internal combustion engine can be avoided fully.
Above-mentioned combustion gas wheel engine, reciprocating piston type band scavenging pump two stroke diesel engine, reciprocating piston type two-stroke gasoline motor, three types motor all are not have degree of vacuum in the firing chamber, by negative pressure air feed, fuel feeding in the cylinder.Finned pump type internal combustion engine is not also by degree of vacuum air feed, fuel feeding, and is identical with them at this point.Above-mentioned three kinds of internal-combustion engines can both proper functioning, all is comparative maturity, widely used internal-combustion engine.Does the finned pump type internal combustion engine that is better than them have anything normally not move again? so the acting principle of finned pump type internal combustion engine is set up fully.
In a word, utilize Modern Internal-Combustion Engine supercharge principle and utilize the automatically controlled fuel feeding principle of Modern Internal-Combustion Engine, novel finned pump type internal combustion engine is bound to succeed in developing, and we are full of confidence to this.
Two, structure
As shown in Figure 3, the finned pump type internal combustion engine critical piece has cylinder body, compositions such as front and rear cover, piston and rotating shaft.Piston and rotating shaft group are one, are contained in by bearing on the front and rear cover of eccentric pivot hole, and front and rear cover links to each other with the cylinder body location.The working surface of piston, diaphragm seal, cylinder sleeve, front and rear cover etc. has all been considered grinding fine finishing, to guarantee the sealing reliability of finned pump type internal combustion engine.Front end has the gear shift of 35:8 tooth, and it plays air inlet wind wheel speedup and motor is carried cooling, Lubricants, and motor is when idling operation, and the rotating speed of air inlet wind wheel is 4000-5000 rev/min, can guarantee engine idling operation; When the high-power output of motor, engine speed is near 10000 rev/mins, and the commentaries on classics scooter of air inlet wind wheel is more than 40000 rev/mins, to guarantee the abundant intake and exhaust of motor.
(1) cooling of finned pump type internal combustion engine is with lubricated
Cooling liquid, the Lubricants of finned pump type internal combustion engine are integrated.It can replace with the machine oil of present motor.Also can be according to present new and high technology, make the water-soluble cooling-lubricant of special antifreeze, graphitiferous powder and multiple high antiwear additive, the feed pump type internal combustion engine uses.The internal operations of finned pump type internal combustion engine mostly is rolling bearing, distinguishes to some extent with conventional engines, so should design the cooling-lubricant that makes new advances, smoke-discharging pollution can not occur to guarantee motor in the wearing and tearing later stage.The cooling water tank structure of finned pump type internal combustion engine is also different with conventional engines, and the cisten mechanism of finned pump type internal combustion engine is similar to the condenser in the air-conditioning system, is installed in air inlet wind wheel front.When the rising of finned pump type internal combustion engine temperature needed cooling, temperature detect switch (TDS) was opened cooling passage, and cooling-lubricant flows back to the fluid storage tank that is positioned at the internal-combustion engine below after the condenser cooling.The cooling-lubricant of finned pump type internal combustion engine is supplied with by the fluid storage tank of external below, helps abundant heat radiation like this, also help the internal-combustion engine stall after, cooling-lubricant can all flow back in the fluid storage tank, and can not scurry in the working room of compression chamber.
(2) annex of finned pump type internal combustion engine
Finned pump type internal combustion engine is continuous running engine, and that it goes without doing is very big for its flywheel.The connection gear of generator, starter motor, engine output shaft etc. can be contained in the same case that is sealed with Lubricants with flywheel.The finned pump type gasoline engine does not need distributor.The igniting of finned pump type gasoline engine, fuel supply signal sensor can be contained on flywheel or the generator.
(3) other correlation technique of finned pump type internal combustion engine
The joint that " improves combustion position " in the universities and secondary specialized schools textbook, think that compound vortex control burning (seeing Figure 11) can make mixed gas be divided into three layers: subsidiary combustion chamber is a rich mixture, and main combustion chamber was a weak mixture, the two intersection is rich mixture slightly.This layer combustion can make the motor acting soft, allows and starts function working under the weak mixture situation excessively, improves combustion position to reach, and reduces the purpose of discharging.
The finned pump type gasoline engine is easy to allow mixed gas form three above-mentioned stratiforms.Because the electronic control injection of finned pump type motor or suction port all are to carry out at cylinder body side face center for natural gas, this just is easy to form " three layers of mixed gas " state of three ring-types.The spark ignitor mixed gas will have the finite concentration scope, and the igniting of finned pump type gasoline engine is to light a fire simultaneously with a 3-4 in one line spark plug, and when idling, fuel supplies fewly like this, easily lights mixed gas at the center, by middle spark ignitor; When improving power, mixed gas increases, and easily lights mixed gas and spreads to both sides from the centre, by contiguous spark ignitor; During peak output, mixed gas supplies at most, easily lights mixed gas and is diffused into the edge, by the edge spark ignitor.This just the finned pump type internal combustion engine gas handling system do not have closure, by the working principle of fuel delivery size control motor acting.
When finned pump type internal combustion engine manufactures diesel engine, also can suitably increase its compression chamber quantity, utilize it extremely to shift to an earlier date the 30-40 ° of principle not too responsive to the acting rotation at fuel injection timing, the diesel oil that transports is heated through exhaust ports, be pressurized to 0.4-0.5MPa (this is the working pressure of conventional gasoline engin electric-controlled injection gasoline) through electric liquid pump again, directly supply with compression chamber by automatical control system after exhaust close, much more simply the diesel engine manufacturing with regard to like this.It does not need the big oil pump feed of conventional diesel; Also need not electric control diesel when supplying with, need install complicated " electronic control final controlling element " additional.As long as suitably increase the quantity of pressing chamber, in certain compression ratio range, producing greatly, the finned pump type diesel engine of pump is possible.
Even so, the finned pump type diesel engine has been compared essential distinction for diesel oil with conventional diesel.Conventional diesel is the plunger pump oil stroke of the big pump of control for diesel oil, reaches the size of control fuel delivery, thereby reaches the purpose of control motor acting.And the finned pump type diesel engine it be continuous at compression end of a period fuel feeding.So, after the finned pump type diesel engine is received engine rotational speed signal,, thereby reach the purpose of control engine power output as long as the size of the size of control charge oil pressure or control fuel supply flow rate also just can be controlled the size of fuel feeding fully.The automatical control system of finned pump type diesel engine is received exhaust feedback signal, computer computing, is sent signal, and the size of control charge oil pressure also just can realize automatically controlled confession diesel oil.
Generally speaking, finned pump type internal combustion engine is in the development stage, has the problem that much will solve, a lot of new material problem, a lot of new technology problem let us and goes to inquire into.But I believe, successfully am bound to greater than failure.As long as finned pump type internal combustion engine gets into smooth, each technical performance index can be compared with traditional internal-combustion engine, and its all scabrous problems all can progressively be readily solved in the maturation in progressively improving.
Three, the comparison of finned pump type internal combustion engine and traditional combustion engine
(1) finned pump type internal combustion engine is compared with traditional combustion gas wheel engine
Finned pump type internal combustion engine is compared with conventional gas turbine (as Fig. 6): traditional combustion gas wheel engine is to utilize the acting of " isobaric Heating Cyclic " principle, gas turbine can not water-cooled, works in hot environment, material is required high, structural principle seems simply, but the actual manufacturing cost height; Fuel economy is also poor.Finned pump type internal combustion engine is to utilize the acting of " thermal expansion " principle, can utilize water-cooled, and structural principle is also very simple, manufactures uncomplicated.
(2) finned pump type internal combustion engine is compared with traditional triangle piston rotary formula motor
Finned pump type internal combustion engine is compared with traditional triangle piston rotary formula motor (as Fig. 5): finned pump type internal combustion engine and triangular-piston rotor formula engine structure are somewhat similar, but actual difference is bigger, and working principle has very big difference.The main distinction is that the traditional triangle piston rotary engine is by the intake vacuum air feed, and finned pump type internal combustion engine does not have intake vacuum, and what lean on is the pressurization system air feed.
Triangular-piston rotor formula engine shaft is an eccentric internal gear, and triangle piston is a ring gear, and cylinder body is oval, manufactures very complicated; Diaphragm seal on the triangular-piston rotor profile can not do big (as Figure 12), when it was communicated with pore by built-in spark plug, high pressure then can leak, and influences engine operation pressure.Finned pump type internal combustion engine is simple in structure, and critical piece mostly is round structure, just can process on the engine lathe of special purpose machine tool or repacking special carrier.The sealing blade (as Fig. 1) of finned pump type internal combustion engine, single-sheet thickness about 6mm, two about 12mm of thickness, when it by built-in spark plug intercommunicating pore process in, first by the time, second guarantee the sealing; Second by the time, first has entered sealing state, can not cause that high pressure then leaks.In addition, because the finned pump type internal combustion engine diaphragm seal can be cooked thickly, gauge wear compensates automatically, and vertically wearing and tearing also can be installed the longitudinal sealing compensating plate additional, allows finned pump type internal combustion engine also can produce excellent sealing in the wearing and tearing later stage.
(3) finned pump type internal combustion engine is compared with the conventional reciprocating reciprocating engine
Finned pump type internal combustion engine is compared with conventional reciprocating reciprocating engine (as Fig. 4): finned pump type internal combustion engine does not have crankshaft ﹠ connecting, does not have the intake and exhaust distribution device yet, and it is one of the simplest internal combustion engine.
With conventional reciprocating piston type gasoline engine, discharge capacity is 0.797 liter; Power is that the minicar motor CA462 that 26 kilowatts/5500 per minutes change compares: the displacement per cylinder of CA462 motor is 0.797 ÷ 4=0.199 liter, and piston thrust crank throw center radius is that 33mm is (because of its cylinder diameter * stroke: 62mm * 66mm).It is φ 180mm that the finned pump type gasoline engine is worked as piston; Cylinder diameter is φ 200mm; The long 140mm of piston-cylinder, pressing chamber are six; Compression ratio is 10.6.Its single compression discharge capacity is about 0.22 liter, the discharge capacity summation is about 0.22 * 6=1.32 liter, because of it is the discharge capacity that rotating shaft fortune circles, be that the discharge capacity of finishing once acting in two weeks of crankshaft operation is compared with reciprocating-piston engine, it is analogous to the conventional reciprocating piston type petrol engine of 2.6 liter capacities.In addition, the thrust of finned pump type internal combustion engine acts directly in the rotating shaft, and the thrust turning radius is about 95mm, and these all are the advantages that reciprocating piston type shipping machine can't be by comparison.
In sum, the finned pump type internal combustion engine major advantage can be summarized as follows:
1, simple in structure, manufacturing process is uncomplicated, and conventional equipment can be finished processing.
2, volume is little, and discharge capacity is big.
3, production cost is low, has the realistic meaning of Development and Production.As the fruit product maturation, after the production in enormous quantities, its main frame price can not be higher than the motor price with volume.
4, in utilization " thermal expansion " principle acting internal-combustion engine, it is one of best type that has many fuel of exploitation or bi-fuel internal combustion engine.
