Diesel Injector Fuel Injector 0445120193 Bosch for Dodge RAM 4500 / 5500 6.7L Cummins Turbo Diesel I6 Enginel

The results show that with the increase of the rotational speed of the injection pump, the maximum injection rate of each hole according to the unit CAM Angle decreases gradually, the circulating injection amount of each hole and the total circulating injection amount of the injector increase gradually, and the cyclic volatility of the three decreases gradually. With the increase of circulating oil quantity, the maximum injection rate of each hole increases gradually, and the circulating fluctuation rate decreases gradually. Under the same working condition, the total circulating injection quantity fluctuation amplitude is not equal to the sum of the circulating injection quantity fluctuation amplitude of each hole, and the total circulating injection quantity fluctuation rate is less than the circulating injection quantity fluctuation rate of each hole.

The fuel injection process is an important factor affecting the operation of diesel engine. Better mixed quality of oil and gas can improve the combustion process of diesel engine, improve the performance of the engine and reduce the emission of pollutants. Fuel injection rule can directly reflect the characteristics of fuel injection process and is an effective means to evaluate fuel injection process. The cycle fluctuation of internal combustion engine refers to the difference of each cycle when the engine is running stably in a certain working condition. The cycle fluctuation of fuel injection process directly affects the cycle fluctuation of combustion process, so that each working cycle can not operate under the best performance, resulting in the reduction of power, economy and emission. At present, the study of engine cycle fluctuation is mainly focused on gasoline engine and alternative fuel engine. The analysis of combustion cycle fluctuation of diesel engine burning light pure diesel is mostly, and the study of cycle fluctuation of each hole of diesel injector is less.
