Diesel Injector Fuel Injector 095000-6070 093400-9150 Denso Injector for Komatsu 6D125 Engine

The second is to listen to the working sound of the injector. When the engine is idling and the engine water temperature is close to the working temperature, use a screwdriver to touch the injector housing and listen to the working sound of the electromagnetic injector. Under normal circumstances, the fuel injector makes a crisp and uniform "click" sound, indicating that the fuel injector injects fuel accurately according to the demand under the control of the engine computer. Resulting in injectors not opening and closing quickly
The third is to check with the cylinder-by-cylinder oil cut-off method. Quickly bring the engine to normal operating temperature, increase the speed to about 2200~2500 rpm and hold it steady, and separate the fuel injector plugs of each cylinder in order to stop the fuel injection of the fuel injector. When the fuel injector plug of a certain cylinder is unplugged, the engine speed drops obviously, which means that the fuel injector of this cylinder is working normally; if the engine speed does not drop obviously, it means that the fuel injector of this cylinder has a problem and should be further disassembled Inspect or replace.
Fourth, the fuel injector coil resistance detection. Adjust the multimeter to the electric resistance and unplug the fuel injector wire plug, and connect the test leads to the wire terminals of the fuel injector respectively. The resistance value of the high-impedance fuel injector is 13.~162, and the resistance value of the low-impedance fuel injector is 3. ~50 If the electric positive is 02, the injector coil is short circuited If the resistance is infinite, the injector coil is disconnected and should be replaced
