20590252 Truck Solenoid Valve

The diesel vehicle Solenoid valve is a device that converts electricity into mechanical work. It is an electrical-mechanical converter consisting of a coil and a valve spool, with the function of mutual conversion, which converts electrical energy into magnetic and mechanical energy. By controlling the work of the Solenoid Valve, the operating state of the diesel engine such as air intake, fuel injection, and cylinder outlet can be controlled.

The operating principle of the solenoid valve is based on Faraday's law of electromagnetic induction and amperes' law. When current flows through the electromagnet coil, a magnetic field is generated. This magnetic field attracts the spool and causes it to contact or disengage from another magnet (or seat), controlling the flow of the liquid or gas.

In diesel vehicles, solenoid valves are mainly used to control fuel injection. When the vehicle starts, the voltage passes through the coil, and the current activates the solenoid valve, causing the valve core to open, allowing the fuel to form a high-pressure spray in the fuel injector. The injector can adjust the switching time and frequency of the solenoid valve according to a specific timing, control the amount of fuel ejected and the angle of spray to achieve the best fuel efficiency and power output under different speeds, loads and environmental conditions.

In short, as a very important component in diesel vehicles, the solenoid valve works simply and practically. In the actual use process, attention should be paid to maintenance and repair to ensure that it works properly, prolongs the service life, and improves the performance and safety of the vehicle.
