The precise control of the injector's injection timing and volume is its core technology. Under different engine operating conditions, such as idling, acceleration, cruising and high load operation, the demand for fuel varies greatly. The injector responds instantaneously to the engine control unit's commands and precisely adjusts the start and duration of injection to ensure that the amount of fuel injected into the combustion chamber is just right. During cold start, the engine needs a thicker mixture to ensure a smooth start, and the injector will increase the amount of fuel injected; while during high-speed cruising, in order to improve fuel economy, it will reduce the amount of fuel injected to make the mixture thinner. This precise control capability not only ensures stable and efficient operation of the engine under various working conditions, but also greatly reduces fuel consumption and the emission of harmful substances in the exhaust gas.

The spray characteristics of the injector is also an important indicator of its performance. Good atomization effect can make the fuel and air more fully mixed to promote the completeness of combustion. This requires a well-designed injector nozzle that can break the fuel into tiny particles and spray them out at the right angle and shape. Modern injectors use a variety of advanced technologies to optimize spray characteristics, such as multi-hole nozzle design and piezoelectric injectors. Porous nozzles allow the fuel to form multiple fine bundles, increasing the contact area between the fuel and the air; piezoelectric injectors are able to achieve faster and more precise spray control, further improving the spray quality.

As automotive technology continues to evolve, so do fuel injectors. From the early single-point injection to today's widely used multi-point injection, and then more advanced direct injection technology, the performance and reliability of the injector has been a qualitative leap. In-cylinder direct injection technology is the role of the injector to play to the extreme, it directly injects fuel into the cylinder, so that the combustion process is more direct and efficient, significantly improving the engine's power and torque output, and at the same time, further reducing fuel consumption and emissions.

However, fuel injectors may also experience some failures during long-term use. For example, clogged injector holes can lead to poor injection, affecting the engine's power performance; solenoid coil failure can prevent the injector from working properly; and aging seals may cause fuel leakage and other problems. Therefore, regular cleaning and maintenance of fuel injectors is an important part to ensure the normal operation of the engine.
As the core component of automobile fuel injection system, fuel injector plays an indispensable role in the running process of automobile. Its precise control ability, good spray characteristics and constantly developing technology provide a solid guarantee for the high performance, low fuel consumption and low emission of modern automobile engines.
