Diesel Injector Fuel Injector 095000-6222 Denso Injector Compatible with Xichai 6dl/4dl Engine for FAW Truck for Jiangling

Diesel engine fuel injector common problems, mainly in the fuel injector nozzle carbon, needle valve stuck, and fuel injector body serious corrosion and so on. In the treatment of these problems and the maintenance of the body, we should follow the scientific and reasonable principle, so as to achieve the pertinence and effectiveness of overhaul and maintenance.

Electrically controlled high pressure common rail system is a new diesel fuel injection system developed in Europe and America in the late 1980s, in which the fuel injector is the core part of the high pressure common rail system. The fuel injector should not only be able to seal 1600-200MPa high pressure fuel, but also have a fast frequency response, and complete an injection in the instant of 0.3-1.5ms. Therefore, high requirements are put forward for the machining accuracy of the injector, especially its core parts. At present, a few developed countries such as Germany, the United States and Japan have mastered the precision manufacturing technology of fuel injector. Our country has become the first big country of automobile production and sales in the world, and is stepping up the development of high pressure common rail system. But the precision manufacturing technology of the key component, oil injector, has not yet been learned in our country, especially the high-end numerical control precision grinding machines for the concave end faces of oil injection nozzle are not self-sufficient. This is an urgent need to develop high precision and applicability of CNC concave end grinding machine.
