Genuine Quality Nozzle DLLA158PN209 105017-2090 Diesel Fuel Injector Nozzle Engine Spare Parts

Avoid using the newly purchased nozzle without cleaning. New fuel injector surface is coated with anti-rust oil, if not cleaned and used directly, the anti-rust oil dissolves when heated, will stick to the fuel injector. If not carefully cleaned, may lead to injectors can not work properly, affecting vehicle performance.

Avoid adjusting the injection pressure rather high than low. Excessive injection pressure will accelerate the wear and tear of the needle valve coupling, shorten the service life, may also lead to high-pressure fuel pipe expansion and cracking and other failures. For the old plunger has been used and the old valve injection pump, allowing the injection pressure than the standard value of 0.985 - 1.47MPa, in order to improve the quality of atomisation.

Avoid adjusting the injection pressure while the engine is running. Adjusting the injection pressure while the engine is running is a very dangerous behaviour, which may cause damage to the injector and even lead to safety accidents. Adjustment of injection pressure should be carried out in the state of engine stopping.

Avoid long-term engine overload. Long-term engine overload will make the fuel and air ratio imbalance, incomplete combustion, resulting in serious carbon deposits around the injector nozzle, accelerate the needle valve coupling wear, shorten the service life of the injector nozzle.

Jealous of replacing the new injector without paying attention to the original specifications. Different specifications of the injector nozzle, the diameter of its spray hole, atomisation cone angle and other parameters are different, the replacement will affect the uniformity of the mixture, the afterburning period is too long, which may lead to fuel injector jamming. Therefore, when replacing the new injector must pay attention to the original specification type.

Avoid using diesel fuel without strict precipitation. The use of diesel fuel without strict precipitation, the impurities may block the injector nozzle holes, affecting the normal work of the injector. Should be used after precipitation and filtration of clean diesel fuel to prevent impurities from intruding into the needle valve coupling parts to aggravate the wear and tear.

Jealous of cleaning injectors do not pay attention to the right number. Cleaning more than two pairs of injectors, do not pay attention to the number of seats, mixed will destroy the precision of the injector, so that the technical state of deterioration. Because the manufacture of fuel injectors is broken weaving inch grinding mounted, so do not allow casual interchange.
