电子控制燃油喷射发动机大多是在原来的传统化油器式发动机基础上,加以改进而成的。不可避免地,它将保留传统发动机的许多机械故障维修内容。这些机械故障的出现,直接影响着电控系统的正常工作,也会诱导电控系统出现与之相类似的故障征候。因此,可以说,正确地判断和检查电控发动机的机械故障,适时地进行合理的维修,是维修好电喷发动机的重要组成部分。 电喷发动机的控制单元(ECU)所控制仅仅 Electronic control of fuel injection engines are mostly based on the original traditional carburetor engine, to be improved from. Inevitably, it will retain many of the traditional mechanical engine failure repair content. The appearance of these mechanical faults directly affects the normal operation of the electronic control system and also induces similar fault symptoms in the electronic control system. Therefore, it can be said that the correct judgments and check the electronic control engine mechanical failure, timely and reasonable maintenance, repair EFI engine is an important part. EFI engine control unit (ECU) controlled only
