Auto Parts Diesel engine fuel injector nozzle DN4S1 for Auto Fuel Common Rail Nozzle injector parts

The fuel injection nozzle of diesel generator set usually refers to the pressure mechanical fuel injection nozzle, which can be divided into oil hole type and oil return valve type from the structure. Among them, the oil return hole type fuel injection nozzle is the most common, because its structure is relatively simple, reliable work, has been widely used on the ship, the new generator set of the fuel injection equipment using the electric injection common rail structure, the structure of the fuel injection nozzle is different from the traditional pressure mechanical type, and has also become the development trend of marine fuel injection equipment.

Put the stuck fuel injector into diesel or engine oil to heat, wrap it with cloth when taking it out, clamp the needle valve with pliers and gradually move, and remove the needle valve from the needle valve body. Put a small amount of smell in the needle valve body, so that the needle valve in the needle valve body repeated activities, until the needle valve can be active in the needle valve body, if the needle valve has burns on the sealing surface of the chassis, it should be ground with abrasive paste, grinding should also pay special attention to grasp the amount and time of abrasive paste, the clean bell valve coupling is installed on the injector, and then adjust the injection pressure.
