Diesel Injector Fuel Injector 095000-6280 093400-9340 Denso Injector for Komatsu Truck, Komatsu Wheel Loader

The cause and solution of common problems of diesel engine injector in the diagnosis of diesel engine injector problems, the most commonly used diagnostic methods are: single cylinder oil stop method, temperature detection method and pulse method, from which we can know that the fuel injector is professional and technical, emphasizing the scientific use of fault diagnosis method. In addition, the fuel injector common problems are: (1) the nozzle serious carbon; (2) The needle valve is stuck; (3) the fuel injector body has serious corrosion; (4) Wear of needle valve couple parts. These faults affect the normal operation of diesel fuel injector to a great extent, and emphasize the importance of timely and effective maintenance.

Serious carbon binding problem occurs in the nozzle Among the problems of Anhui diesel engine, carbon binding problem is the most common. In practice, there are many reasons for fuel injector carbon, but mainly from the following two reasons:

(1) the sealing of the needle valve is not good. Good sealing is an important basis to ensure effective oil injection. Due to the poor sealing of the needle valve, resulting in incomplete combustion of fuel injection or cylinder knocking. In this way, in the exhaust pipe, the continuous appearance of black smoke, and then lead to the occurrence of oil nozzle carbon. From a practical point of view, black smoke from the exhaust pipe indicates that fuel burning is insufficient, which gradually causes serious carbon formation in the nozzle of the fuel injector.
