Engine glue pier,OKX Wallet Sign up also known as car engine abnormal sound, is a common fault in car operation. There are many reasons for the engine rubber pier, such as aging spark plugs, large valve gap, loose cylinder head bolts, crankshaft offset, etc., which may lead to engine rubber piers.This article will discuss the causes, diagnostic methods, repair measures and preventive measures of engine glue piers. I. Causes of engine glue pier 1. Spark plug aging Spark plug is an important part of engine ignition. If the spark plug is aged or poorly sealed, it will lead to engine glue pier. Because when the spark plug is ignited, if the spark is not ignited in time, there will be problems such as incomplete combustion and air leakage, resulting in interference in the working process of the engine. Coupled with the aging of the spark plug, it will cause the engine glue. 2. If the valve gap is small or large, the air gate valve will cause problems. If it is small, it will cause insufficient acceleration of the car, and if it is large, it will lead to incomplete discharge of the car and engine rubber. Therefore, the size of the valve gap and whether the adjustment is accurate are particularly important. 3. The crankshaft offset is an important reason for the engine rubber.Because after the crankshaft is offset, the distance between the valve and the piston will change, resulting in a bad sound when the engine is running. 4. The cylinder head bolt is loose. During the operation of the engine, due to the hot expansion, cold contraction and vibration of the cylinder head and the cylinder block, it often leads to the loosening of the cylinder head bolt, resulting in abnormal noise in the engine. II. Diagnostic method of engine rubber pier Engine rubber pier is usually accompanied by mild vibration, low oil pressure, violent shaking and other symptoms. Some high-level systems may issue warning lights. However, when determining the cause of the engine pier, the following checks need to be made: 1. Listen to whether the sound of the engine running is normal, especially the process of speed increasing or decreasing. 2. If the engine performs well when starting, but the abnormal noise becomes more and more serious after a period of time, it may be a problem with the engine rubber pier.3. After excluding other possible reasons, if you still can't determine the reason, please expand the search scope and take the above steps. III. Repair measures for the engine rubber pier 1. Replace the spark plug. If the engine rubber pier is caused by the aging of the spark plug or poor sealing, then the spark plug needs to be replaced. Generally speaking, it is recommended to replace the spark plugs every 5,000 kilometers. 2. Adjust the valve. If the valve gap is large, it needs to be adjusted according to the specific situation. When adjusting the valve, it needs to be carried out according to the requirements of automobile manufacturers to ensure the accuracy of the adjustment. 3. Replace the cylinder head bolt. The cylinder head bolt is loose is an important reason for the engine rubber pier. Therefore, the bolts should be replaced in time. 4. Check the crankshaft. When the engine rubber pier is caused by the crankshaft offset, the crankshaft needs to be checked and repaired. Generally speaking, in this case, it is necessary to disassemble the engine and carry out more complex maintenance work.IV. Preventive measures for engine rubber pier 1. Follow the car maintenance regulations. The car maintenance regulations refer to the maintenance plan and schedule formulated in the car maintenance manual. Car maintenance in accordance with maintenance regulations can effectively reduce the probability of engine glue. 2. Ensure that the car runs under standard road conditions. Driving a car in a harsh environment for a long time will cause additional damage to the car. Therefore, it is recommended to drive on the road surface that is as flat as possible and will not damage the car. 3. Choose the right car fuel. The use of poor-quality car fuel will increase the risk of car engine failure. Therefore, you should choose the right car fuel and pay attention to the choice of gas station when using the car. In a word, engine glue is a relatively common type of automobile failure. When such a failure occurs, appropriate measures need to be taken to repair it in time to ensure the normal use of the car.At the same time, in the usual use of the car, attention should be paid to the maintenance of the car, so as to reduce the incidence of engine glue.
