Engine pressure reliefThe Global trade finance benchmarkingfunction and maintenance method of the pressure valve. The engine pressure relief valve, also known as the valve pressure relief valve, is a device used to relieve the pressure inside the engine. During the normal operation of the car engine, the compressed gas generated by the piston moving up and down will increase the pressure inside the cylinder. When the pressure inside the cylinder reaches a certain level, these pressures will begin to reversely affect the work of the piston, causing the piston to get stuck. The function of the engine pressure relief valve is to reduce the internal pressure of the engine in time through certain control, so as to ensure the normal operation of the engine. The main functions of the engine pressure relief valve can be summarized into the following three points: 1. Reduce the pressure inside the cylinder. Each cylinder of the engine has a valve relief valve. When the valve relief valve is opened, the high-pressure gas will be released to the outside of the cylinder, thus reducing the pressure inside the cylinder.Two. Prevent the engine from being locked due to excessive internal pressure. During the normal operation of the car engine, the piston produces compressed gas in the up and down movement, which will increase the pressure inside the cylinder. When the pressure inside the cylinder reaches a certain level, these pressures will begin to reversely affect the work of the piston. If the pressure inside the cylinder is too high, it will cause the piston to get stuck, resulting in engine damage. The function of the engine pressure relief valve is to reduce these pressures in time when the internal pressure of the engine is too high to ensure the normal operation of the engine. 3. Improve the stable operation performance of the engine. The engine pressure relief valve can help discharge high-pressure gas, control the flow of gas in the cylinder, and help improve the stable operation performance of the engine. The engine pressure relief valve needs to be cleaned and replaced regularly to ensure its normal operation. If the engine pressure relief valve fails, it will cause the following problems: 1.The engine sound becomes abnormal. When the engine pressure relief valve fails, the valve will be opened to release a considerable amount of residual gas. When the car expands or rejects the operation during operation, abnormal sounds will be heard. Two. Unstable engine operation. When the engine pressure relief valve fails, the pressure inside the cylinder will not be accurately controlled, which will cause the engine to be unstable or even broken during driving. 3. The fuel consumption of the engine increases, and the exhaust gas increases. In the event of the failure of the engine pressure relief valve, a reverse airflow will be formed between the throttle suction and the intake valve in the combustion chamber, which will weaken the pressure in the combustion chamber. This will lead to an increase in engine fuel consumption and produce excessive exhaust emissions. In order to avoid the above problems, we need to regularly check and replace the engine pressure relief valve. Under normal circumstances, it is recommended to carry out a comprehensive inspection of the engine pressure relief valve once a year and replace the faulty pressure relief valve in time.The maintenance methods of the engine pressure relief valve are as follows: 1. If you find that the operation of the car is unstable or there is an abnormal sound when replacing the pressure relief valve, the first thing to do is to check whether the pressure relief valve is faulty. If the pressure relief valve is found to be faulty, the pressure relief valve needs to be removed, cleaned and replaced. Two. Check the pressure relief hole under the pressure relief valve. Sometimes, there will be dirt accumulation between the pressure relief valve and the pressure relief hole, which will cause the pressure relief valve to not work properly. Therefore, when replacing the pressure relief valve, you should check the dirt under the pressure relief hole and clean it up. 3. Check the base of the pressure relief valve. The base of the pressure relief valve is the place where the pressure relief valve is fixed. If there is a problem with the base, it may cause the pressure relief valve to not work normally. Therefore, when replacing the pressure relief valve, you should check whether the base of the pressure relief valve is loose or worn. If so, it should be replaced in time.In a word, the engine pressure relief valve is a very important component in the car engine. It can ensure the normal operation and stability of the engine by controlling the pressure inside the cylinder. If the pressure relief valve fails, it will lead to unstable operation of the car, resulting in serious consequences. Therefore, during the driving process of the car, the engine pressure relief valve must be checked and replaced regularly to ensure the normal operation of the car.
