New 100% Tested Warranty Diesel Fuel Injector Nozzle Dlla154s082 for Dongfeng

Diesel oil contains relatively large impurity particles, which is an important reason for the "burning" of the needle valve of the fuel injector. Diesel filters used in diesel engines are not very capable of filtering, and generally can only filter out impurities larger than 0.0005 mm. If the filter element of the diesel filter is broken at this time, the upper and lower felt pads of the filter element are missing or damaged, and the diesel dirt enters the fuel injector, which may cause the needle valve of the fuel injector to be stuck and "burned to death". Some diesel engines are equipped with a metal rod injector filter element (filter needle) in the fuel inlet pipe joint of the fuel injector. This piece will make the fuel injection

The mouth valve was quickly "burned to death". When it is found that the injector is faulty and no new parts can be found, for the poorly sealed needle valve, you can apply a small amount of toothpaste on the sealing cone surface, first insert the needle valve into the valve seat and grind until the sealing cone surface is ground out a complete line. Then clean the needle valve seat, grind and polish it with engine oil for a while, clean it and put it back for use. If the above method still cannot solve the problem, you can loosen the oil outlet valve of the fuel injection pump of the cylinder, so that the fuel injection pump of the cylinder does not supply fuel, and let the car

Drive to the garage at low to medium speed and overhaul.
