Engine solenoid valve and okx.com loginits principle Brief description Engine solenoid valve refers to the solenoid valve used in the intake and exhaust valve in the engine cylinder. Generally speaking, it is an electronic part of the engine. As an important part of the engine, it can control the valve switch of the engine, affecting the speed and power performance of the engine. So, what is the working principle of the engine solenoid valve? Working principle of engine solenoid valve: The function of the engine solenoid valve is to control the opening and closing of the engine valve through electromagnetic force, and then control the intake and exhaust in the cylinder. Generally speaking, there are at least two valves in an engine cylinder, one for intake and the other for exhaust. The function of the solenoid valve is to enable the valve to open and close automatically, so that the gas in the cylinder can go in and out.The working principle of the solenoid valve is based on the action of electromagnetic force. Inside the solenoid valve, there is a coil and a movable iron heart. When the current passes through the coil, a magnetic field will be generated, which will attract the iron heart and make it move in the direction of the coil, thus opening the valve. When the current stops, the iron heart returns to its original position due to the action of elastic force, and the valve is also closed. In this way, the solenoid valve can control the opening and closing of the valve. Of course, the solenoid valve needs a certain control circuit to open and close the current, which can be controlled by the engine control module. Types and applications of engine solenoid valves There are actually many types and applications of engine solenoid valves. Different engines may use different solenoid valves, but in general, they are all used to control the switches of the valve. At present, there are mainly three types of engine solenoid valves on the market.One is a plug-type solenoid valve, which is easy to install, but requires professional technology for debugging; the other is a threaded solenoid valve, which is relatively simple to install and debug, but requires more accurate installation position and valve cooperation; the third is a switch solenoid valve, which can be used to control The opening and closing of the motor intake and exhaust valve. In terms of application, engine solenoid valves are mainly used in internal combustion engine equipment such as automobiles, motorcycles and ships. With the continuous development of electronic technology, new electronic equipment can achieve more refined valve control, such as traditional throttle control through multi-stage adjustable camshafts, and handing over the control of intake valves and exhaust valves to more flexible electronic control. Conclusion The engine solenoid valve is an important part of the engine, which can effectively control the intake and exhaust of the cylinder.In the design and manufacture of the engine, it is necessary to configure the corresponding solenoid valve according to different needs to achieve the best control effect. Engine solenoid valve is the product of the cross-application of electronic technology and engine technology, which plays an important role in improving engine efficiency and performance.
