一辆天津三峰小客车(6481A型),采用瑞典生产的沃尔沃230G或F型电控燃油喷射发动机。该车在使用中发动机突然熄火,再次起动,发动机就是不着车。 首先检查高压电回路,发现产生的高压电火花正常,且火花塞和高压线无故障,说明点火系统基本正常。 而后检查汽油喷射系统的外围线路和所有电线是否牢固,插接件及电子控制器插头中的端子是否松脱,燃油系统是否有漏油、漏气,喷油器是否堵塞,油路是否通畅,电动汽油泵和油压调节器是否正常。经过上述程序检查,一 A Tianjin Sanfeng passenger car (Model 6481A) uses a Volvo 230G or F-type electric fuel injection engine made in Sweden. The car suddenly turn off the engine in use, start again, the engine is not a car. First check the high-voltage circuit, found that the resulting high-voltage spark normal and spark plug and high-voltage line without failure, indicating the ignition system is normal. And then check the gasoline injection system peripheral lines and all wires are solid, plug and electronic controller plug in the terminal is loose, the fuel system is spilled, leaks, injector is blocked, the oil is smooth, Electric gasoline pump and hydraulic regulator is normal. After the above procedure check, one
