摘要

在现代汽车上，化油器车型已趋于淘汰，电控燃油喷射装置因其性能优越而得到了日益普及。电子喷油装置可以自动地保证发动机始终工作在最佳状态，使其在输出一定功率的条件下最大限度地节油和净化空气。电控发动机燃油喷射系统能很好地适应当今社会对汽车的使用要求，既减少排放，降低油耗，提高输出功率和改善驾驶性能。电控发动机燃油喷射系统以成为现代汽油发动机的主流，并已逐步取代了化油器式发动机。本文详细论述电控燃油喷射系统的发展历史，构成，优缺点和主要部件的组成以及在汽车上的作用，对空气供给系，燃油供给系，电子控制系的组成和各部件的作用等。

Abstract：

On the modern automobile, the carburetor vehicle type tended to the elimination, the electrically controlled Electronic Fuel Injection installment superior obtained because of its performance popularized day by day. The electron blows the equipment to be allowed automatically to guarantee the engine throughout works in the optimum condition, cause sit maximum limit to save gas and oil in under the output certain power condition with the purification air. The electrically controlled engine Electronic Fuel Injection system can adapt now the society well to the automobile operation requirements, also reduces discharges, reduces the oil consumption, enhances the output and the improvement driving performance. The electrically controlled engine Electronic Fuel Injection system into modern gasoline engine mainstream, and has gradually substituted for the carburetor type engine. this paper discusses the development of electronic fuel injection system, advantages and disadvantages, the history of the main parts in the car and the effect of air supply, fuel supply, electronic control components and parts .

Key words: EFI engine Electronic Control Fuel Injection System Construction
