Diesel fuel injectors are key components in the fuel injection system of diesel engines, and they have the following main functions:

Precise fuel metering
Depending on the engine's load, speed and other operating conditions, diesel fuel injectors can accurately control the amount of fuel injected into the combustion chamber. For example, when the engine is idling, the injector will inject less fuel to keep the engine running; when the vehicle needs more power to accelerate or climb a slope, the injector will increase the amount of fuel injected to meet the engine's power requirements and ensure that the engine can maintain good performance and fuel economy under various working conditions.

Forming a good spray
The diesel injector sprays the fuel into the combustion chamber at a certain pressure and angle, so that the fuel is dispersed into fine droplets to form a good spray shape. This can increase the contact area between the fuel and the air, which is conducive to the full mixing of the fuel and the air, creating good conditions for the subsequent combustion process, making the combustion more complete and efficient, thereby improving the engine's thermal efficiency and reducing energy waste and pollutant emissions.

Controlling the injection timing
The injector can accurately control the start and end time of the injection according to the engine's working cycle and combustion requirements. The right injection timing is crucial to the performance and emissions of the engine. Injection too early or too late will lead to incomplete combustion, reduced engine power, increased fuel consumption, and worsening emissions. The injector works with the engine's electronic control system to ensure that the fuel is injected at the best time to achieve good engine operation.

Maintaining injection pressure
The internal structure and working principle of the diesel injector enable it to maintain a certain injection pressure during the injection process. Higher injection pressure helps the fuel to be better atomized and penetrated, especially in modern high-pressure common rail diesel engines. The injector can accurately spray fuel into the combustion chamber under high pressure, ensuring that the fuel can achieve good combustion under different working conditions, and improving the engine's power performance and environmental performance.
