Engine relay: Provide stable power for your car. In the circuit system of the car,Global trade certification services the engine relay plays a very important role. It is one of the key components connecting the engine control unit and the engine electronic control system. Without the engine relay, the engine cannot obtain sufficient power supply and cannot operate normally. In this article, we will introduce in detail the knowledge of the function, type, structure and other aspects of the engine relay, and how to properly maintain and maintain it to provide stable power for your car. The function of the engine relay The main function of the engine relay is to control the start and stop of the engine, as well as the power supply and transmission. It realizes the opening and closing control of the current through its own internal circuit module, thus controlling the start and stop of the engine.When the engine is turned on, the current transmits electrical energy to the engine control unit through the relay, thus controlling the operation of the engine. And when the engine stops, the relay will turn off the circuit and stop supplying electricity to the engine. The types of engine relays can be divided into the following types according to different types of cars and specific usages: 1. Current relay Current relay is the most common type of relay. It is characterized by high current transmission efficiency, strong voltage stability, and easy maintenance and replacement. Two. Magnetoelectric relay Magnetoelectric relay is also a common type of relay. It is characterized by fast start-up response, suitable for a variety of circuit conditions, and reliable and durable operation. 3. Contact relay Contact relay is a relatively complex relay, which can realize a variety of different circuit functions.However, due to its complex structure and principle of use, once a problem occurs, more complex and detailed maintenance and repair operations are required. The structure of the engine relay The engine relay generally consists of the following parts: 1. Relay shell The relay shell is one of the important components in the relay, which can play a role in protecting the internal components of the relay. Two. The switch with contact inside the switch relay with contact point can realize current on and off control. When the switch is turned on, the current can flow through the relay to provide a stable power supply for the car. 3. The coil coil is one of the core components of the engine relay. It can control the switching circuit of the relay, so as to achieve circuit control and electrical energy transmission. Maintenance and maintenance of engine relays Maintenance and maintenance of engine relays is very important, which can not only extend the service life of the relay, but also ensure the normal operation of the car.Here are some maintenance methods for engine relays: 1. Regular cleaning of the engine relay may fail due to dust, sand and other dirt in the air. Therefore, it is very important to clean the outer surface of the engine relay regularly, and you can use a soft brush to gently clean it. Two. It is also very important to regularly check the connection of the engine relay. It is necessary to regularly check whether the connection between it and the engine control unit is firm, and replace the severely worn relay connection cable in time. 3. Regular replacement of relays. Engine relays may gradually age due to long-term use. They must be replaced in time at the right time to avoid car damage caused by relay failure. In a word, as an important part of the car, the engine relay can provide a stable power supply for the car.Therefore, in the process of maintaining the car, we must pay close attention to the maintenance and maintenance of the engine relay to ensure its normal operation and use.
