Engine squeak (engine buzzing) When the car engine buzzes,DigiPlus stock many people will think that the car is working, but if the buzzing continues or becomes louder, then it needs to be noticed. Engine failure will not only lead to a decline in car performance and affect the driving experience, but also pose a threat to safety.This article will introduce the causes of engine buzzing and how to solve these problems. Causes of engine buzzing 1. Engine oil pump with too low engine pressure is a component responsible for supplying engine lubricant. If the engine is found to make a squeaking or buzzing sound, it is likely to be caused by insufficient supply of the oil pump. The working principle of the oil pump is to use a mechanical pump to suck the oil out of the fuel tank and send the oil to the moving parts of the engine for lubrication. If the oil supply of the oil pump is insufficient, the fluid power chain of the engine will become thinner, resulting in runaway or stalling. Two. There are several moving parts in the car engine, such as pistons, connecting rods and crankshafts, and the sliding between these parts requires lubrication. If the engine lubricant is insufficient or has aged, there will be jams, rust, etc.The problem leads to an increase in friction between moving parts and will cause squeaking or buzzing. 3. Throttle transmission system failure. The car throttle system is one of the key components to control the engine speed. If you find the engine squeaking or buzzing, it may be a problem with the trottle chain, trottle torsion spring or trottle circuit assembly, etc. If the trottle drive component fails, it may cause squeaking or buzzing. Four. Faults of engine belts or gears. The belts and gears in automobile engines are key parts that generate movement from the rotation of engine torque. If a buzzing or squeak is found, it may be caused by a failure of the belt and gear. Among them, the belt may have corrosion or aging problems, resulting in buzzing or squeaking. ToothWheel failure may be caused by transitional use, strong vibration, improper gear assembly or lack of lubrication. How to solve the engine buzzing 1. Replace engine oil and oil filter. When using the engine, the car manufacturer will specify what type and level of oil to use. If the same model of engine oil is used for a long time, it may cause the gradual loss of additives in the engine oil, causing the aging of the engine oil, resulting in squeaking or buzzing. In order to avoid this situation, it is recommended to read the instructions of the relevant equipment before replacing the engine oil and oil filter to understand the type and brand of oil to be used. Two. Regularly replace car abnormal noise parts. Automobile abnormal noise parts may become aging due to mileage and usage time, resulting in a buzzing or squeaking sound in the engine. If you find a buzzing sound in the engineOr other problems, such as slow acceleration, obvious black smoke in the exhaust pipe, etc., may be caused by abnormal noise parts. If it is indeed caused by these parts, it is recommended to replace them regularly. 3. Regularly check the car wheels. Sometimes there is a buzzing or squeaking sound, abnormal sound, etc. of the engine, which is caused by the tightness of the car tire or the failure of the tire. In order to avoid such problems, it is recommended to regularly check the wheel, the tightness of the tire and/or whether the tire needs to be replaced. Four. Regular maintenance Regular maintenance of your car can help you check and replace various lubrication and mechanical parts in the engine and related equipment. For example, oil replacement, spark plug replacement, brakes, tire replacement, wipers, etc. must be checked and replaced regularly to ensure that your car maintains good performance under severe road conditions. In summary, the squeak or buzzing sound of the engine is caused by the decline in car performance.If you only want a car to make a slight noise in normal driving, don't worry too much. However, if you find the engine buzzing or squeaking louder and louder, be sure to handle it with caution. By regularly changing the oil, regularly checking abnormal parts, and paying attention to comprehensive inspection and maintenance, this situation can be minimized and the life of your car can be extended.
