The main reasons for the fuel injection nozzle jamming.
1 Diesel fuel is not clean, impurities in the high-pressure oil pipe, so that the needle valve coupling is not closed tightly, the combustion chamber in the high-pressure gas rebound, burned needle valve coupling. In addition, the injector regulator spring, tappet and other parts of the dirt through the injector tappet moved to the upper part of the injector needle valve, or oil road used to prevent oil leakage of cotton rope, lead wire through the high-pressure oil pipe into the injector, will make the needle valve coupling jammed.
2 The machine temperature is too high injector cooling is poor, resulting in the oil valve coupling stuck.
3 The oil valve wear, so that when the injector stops spraying oil drip phenomenon, so that the injector nozzle burning coke accumulation, the occurrence of jammed failure.
4 Injector installation, omission of gaskets or gasket damage, resulting in air leakage, causing the injector local temperature is too high and stuck.
5 The injection pressure is too low, resulting in the combustion chamber of high-pressure gas backflow.
6 Parts manufacturing reasons, such as cylinder head injector mounting holes and injectors with too tight, needle valve body and cylinder head mounting hole clearance is too small, cylinder head injector mounting hole processing too deep.
Product Description
Injection nozzle stuck repair method.
First, the stuck injector into the diesel or oil warming, and then remove the cloth wrapped, and then clamp the needle valve with hand pliers and slowly move, the needle valve from the needle valve body out. A small amount of clean oil drops in the body of the needle valve, so that the needle valve in the body of the needle valve repeated activities, until the needle valve can move freely in the body of the needle valve. If the sealing surface of the needle valve has traces of burns, it should be ground with abrasive paste. When grinding, pay attention to grasp the amount of grinding paste and grinding time. The cleaned bell valve coupling will be installed on the injector, and adjust the injection pressure can be used again.
