Description
Technical field
The present invention relates to field of internal combustion engine, in particular to a kind of rotary combustion engine.
Background technology
Reciprocating piston internal combustion engine (fuel oil, combustion gas spark-ignition engine) is to be by thermal energy caused by fuel combustion
The engine of mechanical energy, now commonly used spark-ignition engine still follow Alto cycle, i.e., air inlet, calm the anger, do work
And four strokes of exhaust, the combustion system of the mixed gas of compression are discharged by sparking-plug electrode, light mixture combustion, four punchings
The cylinder internal volume of journey changes, and drives piston motion to realize by crank connecting link, four stroke operation of spark-ignition engine is former
Reason is, when induction stroke starts, inlet valve is opened, exhaust valve closing, and piston is moved from top dead centre to lower dead center, piston
Top forms certain vacuum degree, and then, combustion mixture is inhaled into cylinder through inlet manifold, inlet valve, when piston reaches lower stop
Point, IC Intake Valve Closes；Compression stroke, when induction stroke ends, piston is moved from lower dead center to top dead centre, inlet and outlet at this time
Door is turned off, and the continuous diminution of volume of cylinder, temperature and pressure constantly increases, until when piston reaches top dead centre, at this point,
Combustion mixture is compressed to the space of the very little above piston, i.e., in combustion chamber, when compression ends, compression is flammable mixed when ending
The burning velocity and pressure for closing gas depend on compression ratio, and compression ratio is bigger, and burning velocity is faster, and economy is better, but compresses
Than it is excessive when, not only cannot further improve burning, will appear the malcombustions phenomenon such as detonation and surface ignition instead；Acting
Stroke, when compression stroke ends, combustion mixture is lighted in sparking-plug electrode electric discharge, and inlet and exhaust valve is closed state at this time,
Combustion mixture burning generates high temperature and high pressure gas and piston is pushed to be moved from top dead centre to lower dead center, so that bent axle is rotated by connecting rod
Acting, until acting terminates when piston reaches lower dead center；Exhaust stroke, when do work end of stroke when, exhauxt valve opens, bent axle passes through
Connecting rod pushes piston to move from bottom dead center to top dead center, and exhaust gas is under itself residual pressure and the thrust of piston out of cylinder
Discharge, this completes a working cycles.
It can show that internal-combustion reciprocating-pisto has the disadvantage that according to four courses of work, gas exchange loss, exhaust valve prolongs
Close later and inlet valve are opened in advance there are one overlap period, and residual gas meets and can not accurately control with into cylinder fresh air
System, has fresh air and is discharged with residual gas, and the residual gas for having higher temperature is detained in the combustion chamber, intake air temperature liter
Height influences intake efficiency；Mechanical movement inertia conversion loss, piston are to be changed into circumference fortune by crank connecting link by linear motion
Dynamic, there are four stops for four strokes, since the loss of the mass motion inertia of piston and connecting rod itself is larger；Thermal friction loses, living
Piston is in top dead centre when plug acting starts, and piston, connecting rod, crank have one section of demurrage, this moment high temperature on same straight line
High pressure gas is unable to quick release, and high pressure is applied to piston, on crank connecting link, and each loading bearing lubricating oil film is made to become
It is thin, increase contact friction, working gas has elastic property, and when being unable to quick release, the energy of a portion is with thermal energy
Form pass to body, and increase heat radiation；The power loss that auxiliary body brings, air inlet and exhaust need camshaft and gas
Men Zu mechanisms realize that inlet and exhaust valve is driven by camshaft, and camshaft timing chain is driven by bent axle, cam needs to overcome valve
Spring drives valve opening and closing, entire air distribution system to be not involved in acting, but to consume the 5~8% of this power, mechanism also becomes
It obtains complicated；Mechanical efficiency is low, and only there are one strokes to do work in four strokes, and non-expansion stroke will consume a part of power；Output
Uneven torque, and be intermittence, when power output is not matched that with load, output torque has pause and transition in rhythm or melody phenomenon, needs larger
The energy of flywheel storage crosses interval point；Stability is poor, due to crankshaft connecting rod system, changes during exercise to all directions stress
Complex, the stability of complete machine operation is poor, needs to increase balance shaft to improve the stability of engine；Fuel oil burning utilizes
Rate is low, and in expansion stroke, acting needs 30 ° in advance~80 ° unlatching exhaust valves before ending, and causes high-pressure combustion gas that cannot have
Effect is utilized and is discharged outside cylinder, in addition, its admission space is equal with the volume that does work, generated high temperature after mixture combustion when acting
The volume of high pressure gas is 6 times of admission space or more, and the partial combustion gases outside isometric(al) still have elevated pressures, still
There is higher power to obtain the starting stage after use value, especially exhauxt valve opens；Combustion chamber operational is temperature limited, influences to fire
Efficiency is burnt, the operating temperature of conventional engines combustion chamber cannot be run in the state of high temperature, when chamber temperature is more than specified
Temperature, then will appear deflagration phenomenon, detonation is tended to occur at before piston not yet reaches top dead centre and generated, the speed of mixture combustion
Degree is propagated with velocity of sound, and extreme high temperature and high pressure gas is applied on piston rod, is damaged to damaging property of engine.
