Maintenance of Electromagnetic Fuel Injector

1) Audiometry check. The operation is shown in Figure 2: after the engine is warmed up, let it run at idle speed: use a screwdriver or a stethoscope to listen to the sound of the injectors of each cylinder. If you can't hear the working sound of the fuel injector of a certain cylinder "click", it means that the fuel injector of this cylinder is not working. In this regard, check the injector control circuit or measure the resistance of the electromagnetic coil. If the control circuit and resistance value are normal, it means that the needle valve of the fuel injector is completely stuck, and the fuel injector should be replaced. If the working sound of the fuel injector of a certain cylinder is very small, it means that the fuel injector is not working normally, it may be that the needle valve is stuck, and further inspection should be done.
2) Static detection. The resistance value between the two pins of the injector is measured as shown in Figure 3. The resistance value of the high resistance fuel injector is generally between 13~162, and the resistance value of the low resistance fuel injector is generally between 2~32
3) Voltage measurement. Measure the voltage between the positive terminal of the fuel injector socket and the engine ground. If the circuit and relay are normal, when the ignition switch is turned on, the detected voltage is the battery voltage.
(4 Check for broken cylinders. After the engine is warmed up, let it run at idle speed; unplug the harness plugs of the injectors of each cylinder in turn to stop the injectors from injecting fuel, and check for broken cylinders. Analysis of judging cylinders: If the injector of a certain cylinder is unplugged After the fuel injector harness plug is connected, if the engine speed drops significantly, it means that the cylinder is working normally; if the engine speed does not drop significantly after the fuel injector harness plug of a certain cylinder is unplugged, it means that the cylinder does not work or is not working well, and further work should be done. examine.
