The fuel injection system of an internal combustion engine is mainly composed of a fuel injector, a fuel pump, a fuel filter, a fuel pressure regulator, and a fuel tank. Among them, the fuel injector is one of the most important components in the fuel injection system, which directly controls the fuel injection. The fuel injection quantity and fuel injection time have a great influence on the working efficiency and emission performance of the engine. The structure of the fuel injector mainly includes single-point and multi-point. The single-point fuel injector is generally installed above the intake manifold to inject fuel to each cylinder, while the multi-point fuel injector is directly installed in each cylinder in the intake port. Each cylinder has an individual fuel injector. In addition, the fuel nozzle is an important part of the fuel injector, which is responsible for atomizing the fuel into small particles for better air mixing after combustion. The structure and size of the fuel nozzle will directly affect the atomization effect and injection volume of the fuel, so it needs to be selected and optimized according to the actual situation.

In addition to the injector, the fuel pump is also an important part of the fuel injection system. Its main role is to draw fuel from the tank and deliver it to the injectors. There are two types of fuel pump structures: mechanical and electronic. The mechanical fuel pump pushes the fuel through the pressure generated by mechanical movement, and the electronic fuel pump controls the flow and pressure of the fuel through the electronic control unit. .

In addition, the function of the fuel filter is to filter impurities and pollutants in the fuel to prevent them from entering the fuel injector and the interior of the engine. The fuel pressure regulator controls the pressure and flow of fuel to ensure the stability of fuel injection quantity and injection time. The fuel tank is used to store fuel and deliver it to the injectors through the fuel pump.

Therefore, from the perspective of the structure of the fuel injection system, the optimal design of the internal combustion engine fuel injection system needs to consider many factors, such as the type of fuel, the structure and number of injectors, the type and flow of injectors, etc. The fuel pump, the filtering effect of the fuel filter, and the working status of the fuel pressure regulator. Taking these factors into consideration, the fuel injection system of the internal combustion engine can work efficiently and stably, and the working efficiency and emission performance of the engine can be improved.
