近年来,进口的轿车大都装用了电子控制的汽油喷射发动机。因电喷系统的电控单元(俗称电脑)故障较难排除,常用一辆同型号车进行比较或将电脑更换的工作方法。笔者认为,电脑坏了可采用积极的修理措施。现列举几个实例:一辆丰田皇冠车(5M—GE 发动机),因机械故障不能发动,维修中人为造成电脑烧坏。我接修后,排除了机械故障,再诊断是电脑故障。更换了电脑中的一个稳压二级管,故障排除。
In recent years, most imported cars are equipped with electronically controlled gasoline injection engines. Due to EFI system electronic control unit (commonly known as the computer) failure is more difficult to rule out, commonly used a model car to compare or change the computer’s working methods. The author believes that the computer can be used to repair the bad repair. Here are some examples: a Toyota Crown car (5M-GE engine), due to mechanical failure can not be started, the maintenance of man-made computer burn out. After I pick up the repair, ruled out mechanical failure, then the diagnosis is a computer failure. Replaced a voltage regulator in the computer, troubleshooting.
