New High Quality Diesel Injector 0 445 110 139 0445110139 For Mercedes-Benz Viano For Bosch Injector Fuel

When the diesel engine is working, the high injection pressure generated by the fuel injector and fuel injection pump injects diesel into the cylinder. The fuel injector is an important part to realize fuel injection in the diesel fuel system. As a very high-precision component, the fuel injector precisely controls the fuel injection quantity through the fuel injection pulse signal sent by the ECU (Electronic Control Unit). If the impurity content in the vehicle diesel oil is high, or the injector nozzle is clogged due to the accumulation of deposits, it will affect the normal operation of the fuel injector, resulting in incomplete mixing of vehicle diesel oil and air, insufficient combustion, and poor engine idle speed. Steady, difficult to start, lack of power and even flameout and other faults. When injector manufacturers develop fuel injection systems, in order to reduce emissions and fuel consumption, improve engine performance, and injection pressure continues to increase, it is necessary to reduce the fit gap between the needle valve and the needle valve body, so it enters the fuel injection system of the engine. Solid particles become one of the causes of potential engine failure
