Diesel Injector Fuel Injector 0445120420 compatible with injector MAN TGS 18.420 to 41.500 /MAN TGX 18.420 to 35.500

Correct use of fuel injectors
To prolong the service life of the injector, the following must be done: 1. The fuel used must be clean. If the diesel oil used is not clean, the needle valve will be accelerated to wear and closed, and the high-pressure combustion gas in the combustion chamber will reverse, causing needle valve accessories Ablation and carbon deposition; pay attention to the daily maintenance of the diesel engine, and do not run it overloaded for a long time to prevent the injector from overheating and causing the needle valve to bite to death. 2 The fuel injection pressure and fuel injection advance angle adjustment of the fuel injection pump must meet the requirements. 3 Maintain and remove the carbon deposits on the fuel injectors in time, and do not damage the nozzle holes, inverted cones and sealing surfaces when cleaning. Check and adjust the fuel injection pressure and atomization quality to ensure proper atomization cone angle. 4 When cleaning and maintaining, you must pay attention to cleanliness. You must choose clean diesel oil, and the container containing diesel oil should also be clean. When cleaning, you must be careful and patient. The action should be light and not damage the needle valve. Do not interchange the matching needle valves and valve seats. 5 When replacing a new needle valve pair, remove the anti-rust oil on the surface of the part to prevent the anti-rust oil from being heated to form carbon deposits, which will cause the needle valve to get stuck. 6 When assembling, the fuel injector must not be skewed, and even parts should be replaced in pairs, and even parts of different models cannot be substituted at will. The gasket should meet the standard and the installation depth should not be changed arbitrarily. When installing, first remove the carbon deposits on the seal copper sheet of the fuel injector. If there is any unevenness or scratches, it needs to be replaced. When locking the screw, both sides should be locked at the same time, and the force should be consistent; crumbs enter.
