It is added in piston, on crank connecting link, keeps each loading bearing lubricating oil film thinning, increase contact friction, working gas has elasticity
Matter, when being unable to quick release, the energy of a portion passes to body in the form of thermal energy, and increases heat radiation；Auxiliary
The power loss that mechanism is brought, air inlet and exhaust need camshaft and valve group mechanism to realize, inlet and exhaust valve is by camshaft band
Dynamic, camshaft timing chain is driven by bent axle, and cam needs to overcome valve spring driving valve opening and closing, entire distribution system
System is not involved in acting, but to consume the 5~8% of this power, mechanism also becomes complicated；Mechanical efficiency is low, in four strokes only
One stroke acting, non-expansion stroke will consume a part of power；Output torque is uneven, and is intermittence, works as power output
When not matched that with load, output torque has pause and transition in rhythm or melody phenomenon, and the energy of larger flywheel storage is needed to cross interval point；Stability
Difference, complex to the variation of all directions stress during exercise due to crankshaft connecting rod system, the stability of complete machine operation is poor,
It needs to increase balance shaft to improve the stability of engine；Fuel oil combustion utilization efficiency is low, and in expansion stroke, acting needs before ending
Shift to an earlier date 30 °~80 ° unlatching exhaust valves, cause high-pressure combustion gas that cannot efficiently use and be discharged outside cylinder, in addition, its air inlet is held
Product is equal with the volume that does work, when acting after mixture combustion generated high temperature and high pressure gas volume, be 6 times of admission space
More than, the partial combustion gases outside isometric(al) still have elevated pressures, still have higher power to obtain use value, especially
Starting stage after exhauxt valve opens；Combustion chamber operational is temperature limited, influences efficiency of combustion, the work temperature of conventional engines combustion chamber
Degree cannot be run in the state of high temperature, when the over proof temperature of chamber temperature, then will appear deflagration phenomenon, detonation is often
It appears in before piston not yet reaches top dead centre and generates, the speed of mixture combustion is propagated with velocity of sound, extreme high temperature and high pressure gas
It is applied on piston rod, damaging property of engine is damaged.
