Because the compression and expansion of the gas of motor carries out in difference cylinder, and compression cylinder can be with different rotating speed operations with expansion cylinder, even compression process and inflation process can finish in incoherent two equipment mutually, therefore can realize that compression ratio is adjustable.
4. can control the compression finishing temperature
Because the compression and expansion of the gas of motor carries out in different cylinders, compression process is cold in can taking, and the characteristic demand that the compression finishing temperature can based on fuel is controlled.
5. can significantly improve the compression ratio of motor, improve the fuel efficiency of motor
Because the combustion heating process of motor is finished in gas distributing chamber, is constant volume heating process, motor antiknock shake ability is strong; This external compression finishing temperature is controlled, and motor is subjected to the impact of fuel knock characteristic little or not affected by it, therefore can significantly improve compression ratio, improves the fuel efficiency of motor.
6. can realize that energy reclaims
Because the compression and expansion of motor carries out in difference cylinder, can store by the mode of compressor absorbed energy with pressurized gas.When being used for on-board engine, Brake Energy can be passed to the work of compressor input shaft drive compression machine by gearbox and reclaim to realize brake energy.
7. same motor can adapt to different types of fuel
Because it is controlled that compression ratio and compression finishing temperature can realize, can regulate and control according to the characteristic of different fuel compression ratio and the compression finishing temperature of motor, to adapt to different types of fuel.
8. can make motor under various loads can both with optimal air-fuel ratio or near the state work of optimal air-fuel ratio because motor can be controlled fuel feed with optimal air-fuel ratio according to parameters such as the actual volume of gas distributing chamber and pressurized gas temperature, motor can be regulated by the mode of regulating gas distributing chamber's actual volume size the power of motor simultaneously, so motor can satisfy the working condition requirement of various power with the working method of optimal air-fuel ratio in wider scope.
9. can effectively utilize the exhaust energy of motor
Turbo charging installation can utilize the energy compression air of the waste gas of motor, can make simultaneously that to keep compression ratio under the different load of motor substantially constant, therefore can effectively utilize the exhaust energy of motor, has improved simultaneously the efficient of fuel.
