Description

Internal combustion engine with annular cylinder and rotary piston

Internal combustion engine with annular cylinder and rotary piston is a kind of dynamic power machine, and it is a kind of for traffic, production, military affairs provide new power, to substitute the internal-combustion reciprocating-pisto of above field as power.

The structure of internal combustion engine with annular cylinder and rotary piston is described as follows with reference to accompanying drawing 1: in the same cylinder body of two half-size scales 1,2 superimposed backs form a circular cylinder that resembles the tire sample major and minor two rotors 3,4 are arranged, fix two pistons 5,6 on the main rotor limit, also two pistons of relative fixed 7,8 on the secondary rotor limit, the hollow sleeve of secondary rotor is enclosed within on the axle of main rotor.The annular cylinder road of major-minor two epitrochanterian pistons and cylinder body coincide, and can rotate in annular cylinder road with rotor.Then have groove can place sealing reed and Stamping Steel Ribbon 9 in the cylinder body, it is piston that each piston has piston ring 10(Stamping Steel Ribbon seal ring, and rotor motion spare moves to seal in cylinder and prevents the leakage of gas).At cylinder body 1 outer gear 11,12,13,14 is arranged then.Gear 11 is fixed on secondary rotor and stretches on the sleeve outside cylinder, gear 12 be fixed on that main rotor is stretched on the axle outside cylinder, gear 13,14 is fixed on parallel another of axle spool on, four gear correlations are: gear 12 is that 13 liang of gear numbers of teeth of driving wheel engaging gear diameter is the same.(the 14th, between exhaust wheel, be divide on the periphery of garden four parts having on the relative limit on the relative in addition limit of tooth do not have tooth) between exhaust wheel 14 engaging gears 11.The diameter of gear 11 exhausts 1/2 of wheel 14 diameters between being, and the number of teeth is the same.The combination of such four gears interlock just forms main rotor and moves with uniform velocity, and secondary rotor then is to walk-stop-variable motion walked, has so just formed the volume-variation of piston in annular cylinder road.The composite structure of internal combustion engine with annular cylinder and rotary piston is (sectional drawing) as shown in Figure 2

The working principle of internal combustion engine with annular cylinder and rotary piston is with reference to four movement travels shown in Figure 3, an intake stroke; When main rotor piston 5 is one group with secondary rotary piston 7,, main rotor exhausts also rotations of wheel 14 with 13 coaxial of gears so exhausting wheel 14 between rotating together by 12 engaging gears 13 of the gear on the clockwise rotation axle.Take turns 14 one side that do not have tooth facing to the gear 11 on the secondary rotor sleeve but this time exhausts, do not have engaging gear 11 secondary rotors not rotate, enter in the cylinder from suction port 19 so the volume between the piston 5,7 in the annular cylinder road increases air.Two compression strokes: main rotor and piston 5 turn over and exhaust gear 14 between 90 ° at gear 12, the one side that forwards tooth under 13 the interlock to begins engaging gear 11, because of gear 11 is to be fixed on that secondary rotor begins to rotate on the sleeve of secondary rotor, because of the diameter of gear 11 exhausts 1/2 of wheel 14 diameters between being, so speed rotation that secondary rotor speed is fast a times faster than main rotor, secondary epitrochanterian piston 7 is compressing piston 5 rapidly, air between 7, when main rotor Rotate 180 °, secondary rotor is Rotate 180 ° also, at this moment the piston 5 of major-minor two rotors, volume minimum between 7 has been finished compression stroke.

Three, expansion space stroke: the effect that one-way valve 15(one-way valve is set on secondary rotor the cylinder body here be when secondary rotor turn over 180 ° finish compression stroke after gear 11 on the sleeve do not exhausted wheel 14 engagements and splashed the thrust that rises the effect of piston 7 past pushers for the bounce-back that prevents to be compressed gas and compression end of a period oil jetting combustion).Secondary rotor can not contrary be turned round.At this moment the cam 17 driving oil pumps 18 of the oil injecting nozzle 16 on the cylinder road between the piston 5,7 on axle spray into fuel oil and make fuel oil rapid splashing promotion main rotor piston 5 rotation works done of rising of burning in hot air in the pressurized air, volume maximum during 270 ° of main rotor and piston 5 rotations between piston 7 and the piston 5, pressure drop to minimum thereupon to be become waste gas and flows to outlet pipe from relief opening 20 and finish expansion space stroke.Four exhaust strokes: most of waste gas flows in the outlet pipe voluntarily behind the expansion space stroke when main rotor has been finished, remaining waste gas between piston 5,7, along with the interlock of gear train, exhaust the wheel 14 one side engaging gears 11 that forward tooth again between making secondary rotor and piston 7 turning handle remainders of exhaust gas are discharged from auxiliary exhaust port 21.When all rotating 360 °, the major-minor rotor finished exhaust stroke.

Two rotors of major-minor also rotate a circle in annular cylinder road around central shaft two the epitrochanterian pistons that rotate a circle like this, because of two groups of pistons 5,7 and 6,8 are arranged, so finish a thermodynamic cycle for 360 ° when the rotation of 5,7 piston set.Another group 6,8 piston set are also rotated 360 ° and are finished a thermodynamic cycle, twice air inlet, compression, burning, exhaust are just arranged, twice output power so major-minor two rotary pistons rotate a circle around central shaft.

Internal combustion engine with annular cylinder and rotary piston is compared 1 certificate with reciprocating IC engine have simple and compact for structure: do not want crankshaft ﹠ connecting, not gas distribution system.2 moving elements are few, piston turns round in annular cylinder and has only compression stroke and expansion space stroke to need sealing, just friction is arranged with cylinder body, air inlet, two strokes of exhaust do not contact with cylinder body, less so wear and tear, four strokes of internal-combustion reciprocating-pisto finish in same cylinder all that not only operating conditions is abominable, and it is also bigger to wear and tear.Various side effect power of the continuous swing of 2 crankshaft-link rods and the back and forth very big vibration of inertia generation, not only consumption of power but also rotating speed are restricted.The piston of internal combustion engine with annular cylinder and rotary piston is directly to rotatablely move merely in annular cylinder, does not produce vibration and reciprocal inertia, and the rotating speed height also can utilize high-revolving rotation to be used to power to reach energy-conserving action.3 internal-combustion reciprocating-pistos are when exhaust stroke, and piston exhaust pressure greatly not only consumption of power also produces exhaust sound.The exhaust stroke of internal combustion engine with annular cylinder and rotary piston is that most of waste gas flows into outlet pipe voluntarily after expansion space stroke is finished, and piston is only to the remaining waste scavenging that does not have pressure, so exhaust consumed power and do not produce noise not.4 annular cylinder and rotary piston machines length as the arm of force of torsion from the piston to the central shaft is constant, transmits the torsion of gaseous combustion work done best.Thereby improve the utilization of the thermal efficiency.And internal-combustion reciprocating-pisto is with the mobile variation of piston in cylinder as the bent axle of the arm of force; When the pressure that produces in the top dead center gaseous combustion when piston was maximum, piston rod crankshaft equalled zero at same straight line upper arm.On the pressure that produces during gaseous combustion utilized well, only the arm of force just became the longest when piston has arrived the cylinder middle part, but pressure at this moment increases with the cylinder body volume and descend, and the thermal efficiency utilizes well.When piston during in lower dead center, the gas pressure that the arm of force equals zero again on the piston becomes minimum.So the thermal efficiency of internal-combustion reciprocating-pisto is not high.The cooling of 5 internal combustion engine with annular cylinder and rotary piston is very simple, after one group of piston has been finished expansion space stroke, cool air just sucks chilled air cools because of the burning cylinder body of heating of rising of splashing with the rotation of the exhaust stroke of secondary rotary piston from suction port, saves to resemble cooling jacket or air cooling equipment the internal-combustion reciprocating-pisto.6 internal combustion engine with annular cylinder and rotary piston, major-minor two rotary pistons, whenever rotating a circle just has the secondary-working stroke to finish the secondary thermodynamic cycle, central shaft secondary output power, and the internal-combustion reciprocating-pisto piston is just finished a force circulation will be in cylinder reciprocal four times, two weeks of main axis rotation are an output power, so the internal combustion engine with annular cylinder and rotary piston of single cylinder equals the efficient of four cylinder reciprocating piston IC engines.

Internal combustion engine with annular cylinder and rotary piston is not only according to body compactness simple in structure is arranged, thermal efficiency height, it is even better and can reach high rotating speed to reduce noise in the energy saving pollution abatement, the power that not only adapts to the various traffic tool comprises that to resemble the aeroengine power big, the rotating speed height, the motor that volume is little, power consumption is low etc. requires.The development and implementation of internal combustion engine with annular cylinder and rotary piston will will produce good effect to promoting development of productivity.
