韩国“现代”汽车大多采用ECU控制电子喷射系统,喷油器则是电喷的供油系中最终执行元件。喷油器的喷油特性,将直将影响汽车的油耗和发动机的其它性能。一些喷油特性,如喷油起始角,喷油时间,是由ECU根据感传器的输入信号经过微处理后的输出信号决定的。但喷油率,即单位时间内喷油器喷油量 Most of South Korea’s “Hyundai” cars use ECU-controlled electronic injection systems. Injectors are the ultimate actuators in the EFI system. Injector fuel injection characteristics, will directly affect the car’s fuel consumption and other engine performance. Some injection characteristics, such as injection start angle, injection time, is based on sensor input signals through the microprocessor after the output signal of the decision. But the fuel injection rate, that is, unit time injector fuel injection
