Automobile engine solenoid valve

Today, the car editor briefly introduced the electromagnetic valve of the car engine to friends. Solenoid valve is an industrial equipment with electromagnetic regulation function, an automatic basic element for regulating fluid, and also an actuator, not limited to hydraulic and pneumatic. Next, let's give a brief introduction to our friends in Bian Xiao.

Electromagnetic valve of automobile engine: introduction of electromagnetic valve

It is used to adjust the main parameters such as direction, flow and speed of medium in industrial control system. The solenoid valve can cooperate with different circuits to realize the expected adjustment, which can basically ensure the accuracy and flexibility of adjustment. There are many kinds of solenoid valves. Different solenoid valves play a role in different positions of the regulating system. The most commonly used are check valves, safety valves, directional control valves and speed control valves.

Automotive Engine Solenoid Valve: Solenoid Valve Function

The electromagnetic valve of automobile idle speed is the executive part in the idle speed adjustment system, which is used to adjust or adjust the idle speed, ensure that the engine emission reaches the standard (requirements) and the engine runs smoothly, and keep the engine idle speed at the lowest speed (within the specified range), which will effectively shorten the fuel consumption.

Automotive engine solenoid valves: classification

Adjust classification

The core of automobile idle speed regulation system is composed of electronic control unit, sensor and actuator. According to the current development, there are two kinds of idle speed control systems: direct throttle type and bypass air type.

Direct-acting throttle: the actuator changes the minimum opening of the throttle to adjust the idle intake.

Bypass air type: the air flow through the idle air channel is adjusted by the actuator through the bypass air channel.

Type classification of bypass air:

Bypass pneumatic idle speed regulating system is divided into: electromagnetic valve idle speed regulating valve, stepping motor type, rotary electromagnetic valve type, duty ratio air ratio type, mechanical type and so on. The following focuses on several common control valves.

Inside is the electromagnetic coil, and the ECU adjusts the current of the coil and the opening of the valve by air ratio.

I saw a three-coil idle speed regulating valve before, which is equivalent to three idle speed regulating valves. The electronic control unit turns on one, two or three to adjust the idle speed.

The above is a brief introduction of automobile engine solenoid valve by automobile editor to friends. After reading the profile of the car editor, do friends have a preliminary understanding of the solenoid valve? Well, today, the car editor will give a brief introduction here.
