Abstract:Vehicle engines are more popular which precisely controlled puters adopt a lot of tech—
niques,such as multiple air valves,high pressure direct injection,andniques,suchvalves,high leamdirect air multiple as level technical the
of vehicle engines is increasingly advanced. In addiction, modern electronic control devices pre—
hensively applied to vehicle engines. Therefore, theses techniques have considerably reduced quantity of
fuel oil exhaust and the pollution by reason of exhaust pared with which of decade.
New—type motor vehicles with clear energy will be accepted by people step by step,and there will devel—
op a series ofbrand-new vacations alternatively.
