Working principle:
Protrusion piston on the compact disk is established beginning on curve bath, protrude the turning to for motor of piston towards the arc central direction motion of this curve bath, rotation along with engine spindle, the compression ring slide block slides under the driving of compression ring slider cam promptly to leaning on into major axes orientation slip, suction chamber forms thereupon and becomes big gradually, and ozone sucks from inlet hole; Protruding the opposite side of piston simultaneously---pressing chamber begins to diminish, and the air in the pressing chamber is compressed.When compact disk turned over several angle with main shaft, the acting valve was shifted to complete closed position by its control channel fully open position under the driving of acting valve driving cam.Compact disk is rotated further with main shaft, when the acting valve is about to closing passage, compression valve is under the driving of compression valve driving cam, shift to open position by the complete closed position of its control channel, at this moment the pressure in the pressing chamber is greater than the pressure in the precombustion chamber, fresh air is pressed in the precombustion chamber, and the gas of combustion in the precombustion chamber is discharged in the acting chamber, and the valve that then does work is with its pathway closure.Compact disk is rotated further with main shaft, when the compression ring slide block skidded off D tee section toroidal cavity, it was zero in other words that compression chamber volume becomes minimum, and the air in the pressing chamber is pressed into precombustion chamber, compression valve is returned its pathway closure under the driving of compression valve driving cam, finishes compression process.Compact disk is rotated further with main shaft, protrudes piston through curve bath, the hole on the compression semi-ring is sealed finish intake process.Then enter next air inlet compression cycle.N on the compact disk protrudes piston and carries out N air inlet compression cycle simultaneously.
Be pressed into certain moment of precombustion chamber at fresh air, if diesel engine then sprays into diesel oil, if petrol engine this moment has been the fuel-air mixture body in the precombustion chamber, at this moment the protrusion piston on the acting dish forwards the curve bath position to main shaft, and acting ring slide block skids off under the driving of acting ring slide block driving cam promptly to deviating from the major axes orientation swing.When main shaft turns over several angle, acting ring slide block slides under the driving of acting ring slide block driving cam, the acting chamber forms, this moment in the precombustion chamber fuel mixture spontaneous combustion (diesel oil) or by spark ignitor (gasoline), its passage is opened in the beginning under the driving of acting valve driving cam of acting valve rapidly, the combustion gas of High Temperature High Pressure enters the burning of acting chamber through passage, the protrusion piston that promotes on the acting dish drives acting dish rotation expansion acting, acting chamber volume becomes big, and the moving main shaft of acting dribbling rotates output torque; The volume of the exhaust chamber of the protrusion piston opposite side on the acting dish diminishes simultaneously, and the waste gas of burning is discharged through exhaust port.The acting dish is rotated further with main shaft, and when the protrusion piston on the acting dish forwarded the position of curve bath position once more to, the acting valve cut out, acting chamber volume maximum, exhaust chamber volume minimum is finished circuit acting exhaust, and the chemical energy of fuel is changed into mechanical energy.Then enter next acting exhaust cycle.N on the acting dish protrudes piston and carries out N acting exhaust cycle simultaneously.
Along with the rotation of main shaft, air sucks constantly that suction chamber, air are compressed constantly that protrusion Piston Compression on the dish enters that precombustion chamber, fuel constantly catch fire in precombustion chamber, combustion gas constantly enters the burning of acting chamber and promotes that protrusion piston on the acting dish expands acting, the combustion gas of having done work is constantly discharged from exhaust by the protrusion piston on the acting dish.The chemical energy of fuel is changed into mechanical energy.
In the different operating modes of motor, the needed air quantity of burning is different.Can drive by air inlet adjustment worm screw and air inlet adjustment cam worm gear ring, open or close the air valve of compression semi-ring upper edge axial centre circumference some, regulate air inflow.The air inlet quantitative change, in order to guarantee compression ratio, the volume of precombustion chamber also will change thereupon; The worm drive worm gear that covers by precombustion chamber rotates, and the screw pair of worm-wheel shaft and plunger moves back and forth plunger, and the volume of precombustion chamber is along with becoming big or reducing.The rotation angle that air inlet adjustment worm screw and clearance volume are regulated worm screw all passes through step motor control by motor control center.
In the said structure, motor is when high loaded process, and the heat load height of the acting side of acting ring, middle ring, acting dish, acting ring slide block spreads out of heat fast by its inner heat pipe, keeps the temperature of component, and it is overheated to be unlikely to produce.Because heat pipe is a moderate temperature heat pipe, motor is when low-load, and the part of acting part keeps higher temperature, has guaranteed the perfect combustion of fuel.

1, N motor that protrudes the disk of piston of band, main shaft revolution 1/N change finishes N air inlet, compression, burning expansion acting, exhaust cycle simultaneously; That is to say that main shaft is whenever goed around finishes N
2Inferior circulation.Combustion gas promotes to protrude piston and drives acting dish, main shaft output torque, has saved shuttle connecting rod.Except that the motor of the disk that protrudes piston with, other engine gas is to making a concerted effort that the pressure of acting dish directly makes progress, because the protrusion piston on the acting dish press circumference uniform distribution, this resultant radial force is zero.Piston is protruded in combustion gas to the acting dish acting area increases when high pressure phase gradually, and pressure reduces thereupon gradually, compares with reciprocating-piston engine that to protrude the impact force that piston is subjected to little many.Except that the motor of the disk that protrudes piston with, the vibration of this motor, mechanical efficiency all are better than Reciprocating engine greatly like this.
2, adopt inlet hole and exhaust port to finish engine breathing, simpler than shuttle inlet and exhaust valve and cam mechanism, resistance and noise ratio are reciprocating type little, and particularly noise reduces greatly.
3, this motor adopts air inlet compression, pre-burning, acting exhaust to finish at different cavitys, and the air in the pressing chamber does not absorb heat or absorb heat few in compression process, and the power that compression need consume is little; Can adopt thermoinsulation material to realize adiabatic combustion in precombustion chamber, gasoline also can be on cloth on acting valve and the passage of acting between the chamber catalyzer realization catalysis light and save ignition system; The temperature that can improve the chamber wall in the acting chamber reduces the thermal loss of combustion gas, and acting allowance for expansion specific pressure capacity reducing is long-pending wants big, can produce more expansion work.The thermal efficiency of comparing this motor with Reciprocating engine has improved.
4, the cavity of this engine structure compactness, particularly compression, pre-burning, acting is to be close to, and the drag losses of air-flow is little.Compression semi-ring, middle ring, acting semi-ring, compact disk, acting dish are round structure and are easy to realize high-precision processing and are easy to realize the highi degree of accuracy assembling.The slide relative face normal force of movement parts compact disk, acting dish and fixed block compression semi-ring, middle ring, acting semi-ring is zero in theory, and the thermal stress and the mechanical stress of part distribute, are out of shape, and are easy to realize the highi degree of accuracy fitted seal.
5, this motor fuel is in combustion process, and the temperature height of chamber wall burns fully.
6, the air inflow of this motor is easy to control with compression clearance volume (precombustion chamber), can realize that whole operating modes of motor are all moved on desirable air fuel ratio and compression ratio, burns, discharges, performance driving economy is good.
7, the powerful quill shaft that adopts of this motor, form by many low power motors, by the total output shaft in clutch and the quill shaft, can selectively will partly or entirely put into operation according to actual conditions, improve the performance driving economy and the reliability of motor.
8, can adopt the heat pipe heat exchanging technology, transmission of heat is fast, if use air cooling, the final temperature of cooling air than circulating cooling system height in the present water many.The cooling system volume is little, the efficient height, and the power of consumption is also little.

Be pressed into certain moment of precombustion chamber at fresh air, if diesel engine then sprays into diesel oil, if petrol engine this moment has been the fuel-air mixture body in the precombustion chamber, when the protrusion piston on the acting dish forwards curve bath (38) position to, cam (5) drives acting ring slide block and skids off its toroidal cavity, then acting ring slide block begins to slide into, the acting chamber forms, this moment in the precombustion chamber fuel mixture spontaneous combustion (diesel oil) or by spark ignitor (gasoline), cam (3) drives the acting valve and opens passage (33) rapidly, the combustion gas of High Temperature High Pressure enters the burning of acting chamber through passage (33), the protrusion piston that promotes on the acting dish drives acting dish rotation expansion acting, the moving main shaft rotation of acting dribbling output torque; The volume of the exhaust chamber of the protrusion piston opposite side on the acting dish diminishes simultaneously, and the waste gas of burning is discharged through exhaust port (36).The acting dish is rotated further with main shaft, and when the protrusion piston on the acting dish forwarded the curve bath position once more to, the acting valve cut out, acting chamber volume maximum, and exhaust chamber volume minimum is finished a circuit acting exhaust, and the chemical energy of fuel is changed into mechanical energy.Then enter next acting exhaust cycle.Two on the acting dish protrude piston and carry out two acting exhaust cycle simultaneously.
Along with the rotation of main shaft, air constantly from two inlet holes enter that two suction chambers, air are compressed constantly that on the dish two protrude that Piston Compression enter that two precombustion chambers, fuel are constantly caught fire in precombustion chamber, combustion gas enters constantly that two acting chambers burnings promote that on the acting dishes two protrude that pistons expand acting, the combustion gas of do work are constantly by the discharge of two on acting dish protrusion pistons.Motor revolution moving one changes like this, finishes four air inlets, compression, work by combustion, exhaust cycle.
Heat load during this engine operation, the heat pipe by high heat load part inside spreads out of heat, keeps part in normal operating temperature work.
In the different operating modes of motor, the needed air that burns is different.Can drive by air inlet adjustment worm screw (7) and air inlet adjustment cam worm gear ring (6), open or close on the compression semi-ring by the air valve (13) of the some of two groups of valve groups of main shaft circumference uniform distribution and regulate air inflow.The air inlet quantitative change, in order to guarantee compression ratio, the volume of two precombustion chambers also will change thereupon; The worm screw (28) that covers by precombustion chamber drives worm gear (29) rotation, and the screw pair of worm-wheel shaft and plunger moves back and forth plunger (27), and the volume of precombustion chamber is along with becoming big or reducing.Air inlet adjustment worm screw and two clearance volumes are regulated worm screw and are respectively joined a stepper motor, motor control center is gathered the various status parameters of motor and the location parameter of worm gear, provide after the follow procedure analytical calculation each stepper motor control amount, reach the purpose of control air inflow and clearance volume.
More than be two embodiments of protruding the motor of piston of each disk band.For the motor of the single and a plurality of protrusion pistons of each disk band, the process of finishing once air inlet, compression, burning expansion acting is all the same, finishes the acting unit too.The motor of the single protrusion piston of each disk band has only an acting unit, and the disk upper piston needs equilibrium block to come balance; The motor of a plurality of protrusion pistons of each disk band, the acting unit is by the main shaft circumference uniform distribution.
