汽油机电控喷油器积炭与汽车动力性、经济性和排放相关性研究

Effect of a Injector Deposits on Power Fuel Economy and Emission of Motor Vehicle

根据电喷车喷嘴积炭的形成机理及影响因素,采用喷嘴积炭模拟技术,建立不同级别的喷嘴堵塞率,通过在AUDI10026E电喷汽车上安装不同堵塞率的喷嘴进行试验,找出喷嘴堵塞率与汽车加速性能。

According to the mechanism and impact factor of injector deposits,a test method for evaluating the effect of automotive spark?ignition engine fuel on electronic port fuel injector fouling by bench procedure is developed. The test can discriminate gasoline with differing fuel injector fouling tendencies in the bench.The test result is presented The effect of different fuel injector fouling on performance of automotive is tested on AUDI 100 2 6E car.The test result shows that the more serious the fouling, the worse of power,fuel economy and emission of motor vehicle
