When we operate the car, the engine often makes an abnormal noise when driving at high speed or accelerating rapidly.In this case, the owner should overhaul it in time so as not to affect driving safety. There are many reasons for the abnormal noise of the engine. Let's take a look at several of them. I. VALE GAP DISAGNORANCE. VALE GAP DISAGGE ADJUSTMENT USUALLY OCCURS AFTER THE ENGINE RUNS FOR A PERIOD OF TIME. When the operating cycle of the engine is completed and the nut on the valve is tightened rather than loose, the valve gap will be misaligned. This condition usually shows a slight hoarse sound and gradually becomes more frequent after the engine warms up. The repair of valve gap displacement requires the disassembly of the engine or intake valve assembly, so it requires high skills and experience. II. Damage to crankshaft bearings. The crankshaft bearing is a very responsible part inside the engine, which is often worn or damaged during use. The wear of the bearing usually leads to increased friction, resulting in abnormal noise.If this sound is particularly obvious when accelerating, it means that the crankshaft bearing is damaged. In order to repair the crankshaft bearing, the engine needs to be thoroughly overhauled and maintained, which requires professional skills and tools. III. The damage to the cylinder liner. If a slight clicking noise is found in the engine of the car, it may be caused by the damage to the cylinder liner. The cylinder liner is an important part that carries the cylinder wall and piston in the car engine. If the cylinder liner is worn or damaged, it will cause abnormal noise in the car. If the engine noise is found to be increasing, it means that the cylinder liner has been seriously damaged and needs to be renovated or replaced. The above situations are only part of the cause of abnormal engine noise, and other situations may also lead to engine noise. However, the abnormal noise caused by any reason needs to bring different degrees of losses to the car owner.Ordinary car owners should pay special attention to the abnormal noise and vibration of the car engine during the driving process, and find and solve problems in time to ensure driving safety. In fact, the noise of the car engine can be avoided through some daily maintenance: 1. Regularly check the engine oil and coolant. The engine oil is like the blood of the engine and needs to be replaced regularly. If there is too much or too little oil, it will cause engine noise. The car owner should regularly check the oil requirements in the driver's manual, and replace the oil filter in time once it is replaced. Two. Regular inspection of the engine belt Belt is part of the engine, which manages many functions of the engine. Regular inspection of the belt can ensure that it is in good working condition and prevent noise. If the belt is found to be twisted or damaged, it should be replaced immediately. 3.Regular inspection of valves is usually a key part of the engine to ensure its normal cleanliness and operation. If the valve is found to be loose or damaged, it should be repaired or replaced immediately to ensure that the engine is working properly. Car engine noise is a very common problem. If it is not repaired in time, it will cause other problems with the vehicle and damage to the engine. As a car owner, you need to always pay attention to the abnormal noise of the car and repair the engine in time to ensure driving safety.
