摘要
如果燃油泵或控制电路出现故障,会造成供油系统没有燃油压力,即使喷油器工作正常,燃油也不能正常喷射.通过对燃油泵开关控制、ECU控制、转速控制、机油压力开关控制等四种典型的燃油泵控制电路的工作原理分析,提出了汽车燃油泵控制电路的一般检修方法.
If the fuel pump or control circuits have breakdown,the fuel injection system will be less fuel pressure, even if the fuel injector is normal, the fuel also can't be injected.By analysis the principle of four fuel pump control circuit which is the fuel pump switch control,ECU control, rotational speed control, it gives the common maintenance way of fuel pump control circuit.
