DLLA153P009 Common Rail Diesel /Fuel Injector BOSCH Injector Nozzle

Because the fuel injection nozzle is squeezed and grinded, the fuel circulation condition is improved, the pressure loss at the inlet of the fuel injection hole is reduced, and the energy of fuel injection is increased, so that the range increases, the range is discussed The range of the oil beam is smaller for the fuel injection nozzle with a diameter mm, so that the penetration is small, and the air near the wall of the combustion chamber cannot be fully utilized into the mixture where the mixture is thinner, and the mixture at the center of the combustion chamber is thicker, resulting in combustion deterioration. The performance of the diesel engine decreases, improves the flow coefficient of the injection hole, reduces the pressure loss at the inlet of the fuel injection hole, increases the circulation energy of the fuel in the injection hole, thereby improving the fuel injection speed, while improving the quality of fuel atomization, it also increases the performance of ZH1105 diesel engine in the calibration working conditions and low-speed large-load conditions have better performance indicatorsConclusionThe flow coefficient of the fuel injection nozzle with a hole diameter of 30mm can be increased appropriately to improve the oil bundle in the combustion of the fuel injection nozzle b1, The range of each injection beam of b2, Spraleb1fore installation test results, the installation test results of the two fuel injectors before and after extrusion, are shown in the figure B1: The research and design of voltage-controlled electric power steering system at low load, 65 passed and reversed.
