The Global trade news aggregationsound of the engine knocking on the cylinder appears frequently, and the owner looks sad. After the car is on the road for a period of time, some car owners will encounter the problem of engine "knocking on the cylinder". This kind of sound is annoying. It not only affects the driving comfort, but also causes great damage to the service life of the vehicle. So, what is the sound of the engine knocking on the cylinder? How to solve it? I. What is the sound of the engine knocking on the cylinder? The sound of knocking on the tank sounds scary, but it is not a dangerous sound. The sound of knocking on the cylinder is usually made by some parts of the engine. TheseComponents include pistons, connecting rods and crankshafts, etc. When these parts are running, they will frequently collide with each other, resulting in a knocking sound. When the knocking sound becomes louder and louder, it usually means that there is a problem with some parts of the engine. II. What causes the engine to knock on the cylinder? There are various reasons for the sound of the engine knocking on the cylinder, and the following situations are relatively common: 1. Lack of oil and lubrication is a key factor for the smooth operation of the engine. When the engine is running, the oil will form a lubricating film between hundreds of parts to prevent them from wearing and wearing out. If the level of oil is too low, the oil pump will not pump enough oil, which may lead to damage to the piston, connecting rod and crankshaft and the sound of the engine knocking on the cylinder. Two. The exhaust system is blocked. The exhaust system is the channel for the vehicle to discharge exhaust gas. When the exhaust system is blocked, the exhaust gas cannot be discharged, thus affecting the engine.These adverse effects include increasing the pressure of the cylinder block, causing the engine to overheat and knock on the cylinder. The reason for the blockage of the exhaust system may be the internal blockage of the exhaust pipe, the numbness in the exhaust garbage or the metal parts falling into the exhaust duct. 3. Engine gas distribution system problems When there is a problem with the engine gas distribution system, it may cause some parts of the cylinder head to lose lubrication and cooling. This may cause the heat of these parts to be too high, resulting in the sound of knocking on the tank. This problem is usually caused by coolant leakage, pump or fan failure, and other cooling-related problems. III. How to solve the sound of engine knocking on the cylinder? Although the sound of the engine knocking on the cylinder is not very dangerous, it still affects the performance and reliability of the engine. Here are some ways to solve the sound of engine knocking on the cylinder: 1. Check the oil level. First of all, you should check the oil level.If you find that the oil is too low, you should add the oil in time. If the oil is on the correct horizontal line, but the vehicle still makes a knocking sound, there may be a problem with the oil pump or other oil parts. Two. After replacing the oil filter and checking the oil level, it is also necessary to check whether the oil filter is blocked. If so, please replace the oil filter immediately. 3. If the above two methods do not work to replace the crankshaft bearing, it may be necessary to replace the crankshaft bearing. This is because the crankshaft bearing is one of the most easily damaged parts in the oil pump, which will affect the performance and reliability of the engine when damaged. Four. Check the exhaust system. If the knocking sound of the cylinder is caused by the exhaust system, the exhaust pipe and silencer should be checked immediately. If it needs to be replaced, it should be replaced in time. 5. If the above methods do not solve the knocking sound of the vehicle parts, it may be necessary to replace some parts of the vehicle.For example, parts such as connecting rods, pistons and crankshafts may need to be replaced. But it takes a certain amount of time and money. In short, although the sound of the engine knocking on the cylinder is not a fatal problem, it will have an adverse effect on your vehicle. If this happens, please don't ignore it. You should take immediate action to check and repair the engine to ensure that your vehicle is safer and more reliable on the road.
