High Quality Mining Truck Bulldozer Loader Construction Machinery Fuel Diesel Engine Excavator Injector

The fuel injector of a diesel engine, as the "heart component" of the fuel system, its technical accuracy and working stability directly determine the overall performance of the engine. Structurally, it is composed of core components such as fuel injectors, needle valve pairs, electromagnetic coils (electrically controlled type), return fuel valves, and pressure regulators.

Among them, the number of holes, hole diameters, and spray angles of the fuel injectors need to be precisely matched according to the shape of the combustion chamber. Common multi-hole fuel injectors can atomize fuel into particles with diameters of 5-30 microns, ensuring the formation of a combustible mixture with high-temperature and high-pressure air.
