The fuel injection pump, fuel injector and high-pressure oil pipes connected in the diesel engine fuel supply system form a high-pressure oil circuit, also known as the injection system, which is a key part of the entire diesel engine fuel supply system. Among them, the fuel injector is an important part to realize fuel injection in the fuel supply system of the diesel engine. Its main function is to spray the high-pressure fuel supplied by the fuel injection pump into the combustion chamber of the diesel engine, atomize the fuel into fine oil particles, and distribute them appropriately according to certain requirements. in the combustion chamber]. As the last link of fuel injection into the cylinder, the performance of the fuel injector directly affects the combustion process of the diesel engine. The smaller nozzle diameter has higher fuel injection pressure, which can make the diameter of the sprayed oil particles smaller, the relative penetration of the oil beam is larger, and the spray cone angle is increased. With the development of the automobile industry and the continuous improvement of environmental protection requirements, the traditional straight-hole nozzles have gradually failed to meet the emission requirements of the new international standards. Relevant studies have shown that the use of inverted tapered nozzle holes can effectively improve the atomization effect and further increase the flow coefficient of the nozzle holes. Therefore, it is necessary to use fluent to numerically simulate the fuel flow in the diesel engine injector
