How to comply with EU trade regulations

Car engine water temperature monitoring Car engine water temperature refers to the temperature of the engine circulating coolant,How to comply with EU trade regulations which is one of the important indicators of engine performance and life. With the progress of automobile technology and the continuous updating of engine design, the water temperature monitoring system has become one of the important parts of automobile design. 1. The role of water temperature. First of all, the water temperature of the car engine is crucial to the performance and life of the engine. When the water temperature of the engine is too high, it will cause the metal parts inside the engine to deform due to thermal expansion, resulting in failure or even bursting. In addition, excessive engine temperature will also reduce the lubricity of the oil, thus increasing the friction and wear of the oil and further shortening the life of the engine. Therefore, it is very important to closely monitor the water temperature of the engine to ensure the normal operation of the engine.Two. Composition of water temperature detection system Water temperature detection system is generally composed of temperature sensor, water temperature meter, water temperature alarm, control module and related harness. Among them, the temperature sensor is mainly responsible for detecting the temperature of the engine circulating coolant. The water temperature gauge shows the engine water temperature through a pointer and a dial. When the water temperature of the engine is too high, the water temperature alarm will sound a warning sound or flash a warning light to remind the driver to overhaul the engine. The control module is responsible for receiving the signals of the temperature sensor and converting them into the electrical signals required by the water temperature gauge and water temperature alarm, so as to realize the monitoring and alarm functions. 3. Under normal circumstances, the water temperature of the car should be kept within the normal working range. When the engine water temperature is abnormal, there are often the following reasons: (1) The water pump fails: the water pump isIf the pump of the engine circulating coolant fails, it will cause the circulating coolant to be unable to circulate, thus raising the engine water temperature. ( 2) Radiator blockage: The radiator is a key part of engine heat dissipation. If dust, silt, rust and other impurities accumulate inside the radiator, it will affect the heat dissipation effect and lead to abnormal water temperature. ( 3) Insufficient circulating coolant: If the engine circulating coolant is insufficient, it will cause the circulating coolant to be unable to circulate and increase the engine water temperature. Four. How to deal with abnormal water temperature When the engine water temperature is abnormal, we should take timely measures to solve the problem. Specific methods include: (1) Check whether the circulating coolant is sufficient, and add or replace the circulating coolant in time. ( 2) Check whether the pump fails, and replace the pump in time if it fails. ( 3) Check whether the radiator is blocked, clean or replace the radiator.(4) Check the temperature sensor. If it fails, it should be replaced in time. 5. In summary, the water temperature monitoring system of the automobile engine is an important part of ensuring the normal operation of the automobile and prolonging the life of the automobile. Timely detection and treatment of water temperature abnormalities is crucial to maintaining the safety of drivers and passengers and the health of cars. Therefore, we must attach great importance to the maintenance and upkeep of the water temperature monitoring system to ensure that the car is always in a safe and reliable state.
