The main actuators of an automotive electronic control system include fuel injectors, igniters, idle speed control valves, cruise control solenoids, throttles, and fuel pumps.

These components work together to ensure efficient operation of the automotive electronic control system, thereby improving engine efficiency and stability.

The fuel injector is a key component. Its primary task is to inject fuel into the cylinder in a specific spray pattern. Its operating condition directly affects fuel atomization and combustion quality. Precise control of the injector is crucial for improving fuel utilization, reducing emissions, and optimizing engine performance.

The igniter generates a high-voltage spark to ignite the combustible mixture in the cylinder, ensuring proper engine combustion. Precise control of the igniter directly affects the efficiency and stability of the combustion process.

The idle speed control valve is another important actuator. It adjusts the idle air intake volume according to the engine's operating conditions, thereby stabilizing the idle speed. The idle speed control valve ensures a stable engine speed during idling, thereby improving fuel economy.

The cruise control solenoid controls the throttle opening to maintain the set speed when the vehicle is in cruise mode. By adjusting the throttle opening, the cruise control solenoid precisely adjusts the engine's power output, allowing the vehicle to travel at a constant speed.

The throttle valve is another important actuator. By varying its opening, it controls the amount of air intake, which in turn affects the engine's power output. Precise throttle control is crucial for improving engine responsiveness and power output.

The fuel pump is responsible for transporting fuel from the tank to the fuel system, providing sufficient fuel pressure to ensure proper operation of the injectors. Stable fuel pump operation is crucial for the proper functioning of the entire fuel system.

These actuators work together to ensure the proper operation of the vehicle's electronic control system, enabling efficient and stable engine operation, thereby improving the vehicle's overall performance and fuel economy.
