What is a car solenoid valve? The most obvious symptom is that a car solenoid valve is broken.

Car solenoid valve What is it

< span style="font-size: 16px;">Automobile solenoid valve is an actuator of the electronic control system. According to their functions, they can be divided into shift solenoid valves, locking solenoid needle valves and pressure regulating solenoid needle valves. According to its working mode, it is divided into switch type solenoid valve and pulse type solenoid valve.

1. Principle of automobile solenoid valve: When the power is on, the solenoid coil generates electromagnetic force to lift the closing member from the valve seat, and the valve opens;when the power is off, the electromagnetic force disappears, and the spring presses the closing member on the valve seat, and the valve closes. Solenoid valve uses electric energy to flow through a coil to generate electromagnetic attraction to attract the valve core (overcoming the spring or self-gravity). Divided into two categories: normally open and normally closed. Usually used to cut off the flow of oil, water, gas and other substances. Cooperate with electrical equipment such as pressure and temperature sensors to achieve automatic control.

2. Principle of direct-acting solenoid valve: When the power is on, the solenoid coil generates electromagnetic force to lift the closing member from the valve seat, and the valve opens;when the power is off, the electromagnetic force disappears, and the spring presses the closing member on the valve seat, and the valve closes. .

The most obvious symptom of a broken car solenoid valve< /span>

A broken car solenoid valve will cause increased fuel consumption, the smell of gasoline, a rattling sound during normal driving (not idling), and difficulty in starting when the engine is cold started. The car will stall easily afterward, the speed will fluctuate high and low when idling, and the vehicle will be unable to accelerate while driving.
