When driving a car, the engine is one of the most important parts, and engine noise is one of the common problems for drivers. If your vehicle has an abnormal engine noise, you must take immediate measures to prevent the problem from aggravating and avoid causing risks to other vehicles and pedestrians.There may be many reasons for the abnormal sound, some of which may be mild, but others may be serious. If these problems are ignored, it will lead to very serious consequences. The following are some common reasons: 1. Oil pump problems Damage to the engine oil pump or oil line, or the oil pump stops working may be one of the reasons for the abnormal noise of the engine. This usually causes the engine to make abnormal noise as it accelerates, and the vibration will also become louder. Two. Piston ring wear The wear of the piston ring will cause abnormal noise, especially when the engine is running, the noise will be more obvious. Obtaining a new set of piston rings and replacing them is the best way to solve this problem. 3. The aging of the cylinder liner may cause abnormal noise between the cylinder and the piston rod of the engine. In this case, it is usually necessary to replace the cylinder liner. Four. Chirping is usually caused by friction between the belt and the pulley.Tire balance may also cause engine chirping. For such problems, we need to check and maintain, and we can add some lubricating oil to solve this problem. V. Improper valve gap adjustment If the valve gap of the engine is improperly adjusted, it may lead to many problems, including engine clicking, engine shutdown and other problems. Adjusting the valve gap is the best way to fix this problem. VI. Rust problem The engine may have rust problem, which will cause abnormal noise of the engine and affect the performance and life of the engine. When the user finds a rust problem, the vehicle should be sent to a professional car repair shop for inspection. VII. Fuel emulsification When water enters the fuel supply system, it will form fuel emulsification, which may lead to abnormal engine noise. The best treatment for fuel emulsification is to replace the fuel, clean the supply system and the fuel injection system.VIII. The fundamental reason for the wear of connecting rod bearings and crankshaft bearings is periodic maintenance and lack of oil. The engine will make abnormal noise when accelerating and working. When we find the problem, the best way is to replace the new bearing. The above are the common causes of abnormal engine noise, so if you hear abnormal noise from the car engine, please contact the auto repairman as soon as possible. For yourself, you should not try to fix the car problem by yourself, because incorrect operation may cause more problems. At the same time, regular maintenance of your car to ensure its normal operation can keep you away from many car problems, thus improving safety and reliability, and prolonging the service life of the car. Finally, I would like to emphasize that the abnormal noise of the engine does not mean that it cannot be used. But we can't ignore these voices, because not dealing with them may lead to bigger problems and dangers.If your vehicle starts to make abnormal noise, please make sure to transport it to a professional car repair shop for inspection and repair in time.
