Good Quality Common Fuel Injector 0445110279 0 445 110 279 Injector for BOSCH System Engine Parts

The fuel injector assembly is referred to as the fuel injector. When disassembling and assembling, we should carefully clean, especially the newly replaced fuel injector couple parts. Sometimes, the spray quality of a good quality injector is removed, cleaned and reassembled, but the spray quality deteriorates and can no longer be used. This is because after the use of the nozzle needle valve cone and the nozzle needle valve body taper hole sealing ring belt has been worn, but it is still well sealed, once removed and reinstalled, the needle valve in the original sealing position of the needle valve body is damaged by the needle valve rotation. Therefore, the injector should not be disassembled blindly without the injector tester testing and confirming that it must be disassembled. For the fuel injector with the gasket for the cone pad, such as the fuel injector of the Dongfeng diesel engine and the diesel engine of the Hangzhou diesel engine series, before loosening the nozzle tight cap, the cone pad should be removed first, so as to avoid the nozzle needle valve body held by the cone pad, rotating with the nozzle tight cap, resulting in the nozzle needle valve body positioning pin broken, Even make the injector shell and the nozzle needle a valve body positioning pin hole cracking [for the shell with a positioning pin, such as faw big firewood and faw tin firewood series diesel engine, Dongfeng diesel series diesel fuel injector, before loosening the nozzle tight cap, should first unscrew the injection pressure adjustment screw, so as to avoid the nozzle couple parts in the nozzle spring pressure outside, The positioning pin produces a large torque, so that the positioning pin break, and even make the pin hole crack.
