Description

Combustion engine with baffle plate rotary-piston

The present invention relates to a kind of rotor internal combustion engine.The rotor internal combustion engine of forming by stator, rotor, dividing plate, rotor shaft and Stamping Steel Ribbon etc. particularly.

In reciprocating piston explosive motor in the past, in order to obtain rotating power, must promote bent axle by connecting rod by piston just can obtain, in order to control intake and exhaust, generally to control by camshaft and air inlet and exhaust valve, each cylinder is sequentially fired also must be finished by distributor, when further improving engine revolution, piston, the reciprocal inertia force of valve mechanism sharply increases, and bearing load is strengthened, and vibrations strengthen, and may destroy the proper functioning of valve mechanism, so its complex structure, poor reliability, part is various in addition, engine weight is big, vibrations are big, and energy conversion efficiency is low, and environmental pollution is big.

In rotary engine in the past, stator and rotor decentraction, rotor is done eccentric motion in stator, the power output of this sealing for rotor, cooling and rotor shaft brings very big difficulty, just can finish four stroke cycle owing to rotor whenever rotates a circle, so have only a burning work done point, therefore can not possess the change displacement function, rotor shaft will bear great shear forces simultaneously, and the aspirated volume of this motor equals combustion volume, and it can not reach the function of active boost.Therefore this engine structure complexity shakes greatly, and noise is big, and manufacture difficulty is big, the cost height.

Purpose of the present invention is cancelled connecting bar and crankshaft exactly, and cancellation gas distribution system and distributor make rotor produce uniform, continuous rotating power, and maintenance are concentric with stator.Thrust only acts on the maximum radius place of rotor, moment output such as remains, and the size of the arm of force and corner have nothing to do.Because when the rotor of being inlayed with 4 integral multiple five equilibrium by dividing plate and the stator of each unequal internal diameter do relative motion, whenever revolve three-sixth turn and can finish four stroke cycle divided by 1/4th of dividing plate sum, so when rotor has 4 dividing plates, have only a work done point, whenever revolve three-sixth turn and finish four stroke cycle, be equivalent to 4 cylinders.2 work done points are arranged during 8 dividing plates, and 180 degree are finished four stroke cycle, are equivalent to 8 cylinders.3 work done points are arranged during 12 dividing plates, and 120 degree are finished four stroke cycle, are equivalent to 12 cylinders, by that analogy.Have the symmetrical work done point more than 2 when having 8 dividing plates above, so rotor shaft will not be subjected to shearing force, bearing load reduces greatly, by closing wherein partial-air admission pipe, is not worked in the partial combustion chamber simultaneously, to obtain becoming the function of discharge capacity output.Because therefore the suction chamber volume can will have the active boost function greater than combustion chamber volume.In sum, this motor power per unit of volume is big, and the specific power quality is little, simple in structure, number of spare parts is few, lacks more than 50 percent than common piston engine part number, can use low octane value gasoline under identical compression ratio, environmental pollution reduces greatly.

With reference to the accompanying drawings combustion engine with baffle plate rotary-piston is elaborated below: accompanying drawing 1 is that 8 combustion engine with baffle plate rotary-piston plan views are arranged, and accompanying drawing 2 is a sectional side view.Rotor (4) is the center of circle with rotor shaft (12), drive dividing plate piston (2), (6), (10), (15), (19), (23), (29), (32) are moved to right rotation in stator (24), dividing plate under the acting in conjunction of centrifugal force and Returnning spring (17) and stator inner surface, just to-and-fro motion in dividing plate is poor.Per 2 dividing plates and rotor outer surface, stator inner surface, both sides end cover of engine (3) internal surface and two side ends face seal bar (35) form dynamic airtight space.When rotor dextrorotation (36), the space of forming with (2) etc. by dividing plate (32), enter induction chamber (3) from exhaust area (33), because the radius of induction chamber is greater than the radius of exhaust area, airtight space is extended, negative pressure appears in induction chamber, and suction stroke begins, and combustion gas is inhaled into induction chamber by suction tude (1).Airtight space by dividing plate (2) is formed with (6) enters compressing area (7) from induction chamber, because the radius of compressing area is compressed less than the radius airtight space of induction chamber, the air pressure of compressing area raises, and compression stroke begins.The airtight space of being formed with (10) by dividing plate (6), enter firing chamber (11) from the compressing area, spark plug this moment (9) is lighted a fire immediately, the fuel gas buring work done, because the radius of firing chamber (11) is greater than the radius of compressing area (7), so the suffered pressure of dividing plate (10) is greater than the pressure of dividing plate (6), thereby rotor obtains the dextrorotation Driving force, expansion space stroke begins.Because dividing plate slips over igniting semicircle recessed (8), (28) in a flash, makes the prime high-temperature fuel gas light subordinate's combustion gas, this moment, spark plug was not worked, and can make the automatic chain burning work done of motor yet.The space of being formed with (15) by dividing plate (10), (11) enter exhaust area (16) from the firing chamber, because the radius of exhaust area is less than the radius of firing chamber, so the space is compressed, waste gas is discharged by outlet pipe (13), and exhaust stroke begins.So far the upper half four stroke cycle is finished.In like manner the space formed with (19) of dividing plate (15) enters suction stroke, and combustion gas is inhaled into induction chamber (20) by suction tude (18).The airtight space that dividing plate (19) is formed with (23) enters compressing area (25), and compression stroke begins.The airtight space that dividing plate (23) is formed with (29) enters firing chamber (30), and combustion gas is by spark plug (27) igniting, and expansion space stroke begins.Rotor obtains the dextrorotation Driving force.The space that dividing plate (29) is formed with (32) enters exhaust stroke, and waste gas is discharged by outlet pipe (31), and the lower half four-stroke is finished.So far two four-stroke end cycles.Dividing plate (32) enters induction chamber (3) from exhaust area (33) again with the space of compositions such as (2), and suction stroke begins.Therefore begun the second period circulation again, repeated successively not stop.

(5) sit screw for motor is fixing, (14) be cooling water passage, (21) be rotor cavity, (22) sit for motor is fixing, (26) be motor assembling screw, (34) be end-face seal ring, (38) are the end cap cooling water passage, and (39) are the rotor cooling oil pipe, (40) be bearing, (41) be the bearing cap fastening screw trip bolt, (42) are the rotor cooling oil passage, and (43) are the cluster engine cartridge screw, (44) be bearing cap, (45) be the seal ring pressure spring, (46) are the Stamping Steel Ribbon pressure spring, and (47) are the rotor shaft packing ring.
