Diesel Injector Fuel Injector 0445110919 Bosch for Dongfeng

(1) Use the diesel engine rationally and choose diesel according to the season. The matching accuracy of the needle valve couple of the fuel injector is extremely high, and the diameter of the nozzle hole is very small, so the clean diesel oil of the specified brand must be selected strictly according to the seasonal changes, otherwise the fuel injector will not work normally. (2) Ensure that the working temperature of the diesel engine is normal. To ensure this, it is necessary to calibrate the fuel supply time and valve timing, and ensure that the diesel engine does not work under long-term overload. In addition, it is also necessary to ensure that the technical state of the cooling system is normal and the water temperature is suitable (kept between 80~90C). When overhauling diesel engines, carefully remove the carbon deposits around the combustion chamber, intake and exhaust valves, pistons, cylinder liners, exhaust pipes and fuel injectors, and repair or replace them according to their technical status. Otherwise, there will be too much carbon deposit in the above places, which will cause poor heat dissipation of the engine, poor exhaust, and high local temperature, which will burn the fuel injector assembly. (3) Before using the new fuel injector, the anti-rust oil must be removed . New fuel injector couplers are coated with anti-rust oil. Due to the high viscosity of the anti-rust oil, it is not easy to be dissolved by diesel oil at room temperature. If it is installed and used directly without cleaning it, the atomization performance of the fuel injection will be affected, and the needle valve will be easily stuck.
