Development and Energy Saving Technology of Automobile Power System

Liu Zhixiang

Abstract：This paper summarizes the current main power systems and energy-saving technologies of power systems by introducing the development of automotive power systems， including engines， hybrid vehicles， electric vehicles and fuel cells. Focusing on the actual commercial vehicle as an example， various power systems are explained. The electronically controlled injection technology of the engine， the variable air intake system， and the electronically controlled common rail injection technology of the diesel engine are introduced. The form of the hybrid system， and the advantages and disadvantages of pure electric vehicles are introduced.

Key words：vehicle powertrain， hybrid power， electric vehicle

汽車(chē)不僅帶來(lái)了巨大的經(jīng)濟(jì)效益，推動(dòng)了社會(huì)發(fā)展，也產(chǎn)生了大量的尾氣排放與空氣污染。（剩余4979字）
