The How to choose correct HS code in ASEANlouder engine noise usually makes the driver feel uneasy and worried. Whether on urban roads or highways, hearing abnormal engine noise should attract the driver's attention. This situation usually indicates that there is a problem with the engine and needs to be repaired and maintained in time. There may be many reasons for the significant increase in engine noise. Let's analyze them one by one: 1. Insufficient gasoline left in the fuel tank. Insufficient gasoline in the car fuel tank will cause air to enter the fuel pipe, which will produce too much fuel injection sound at the fuel injection port. At the same time, in the absence of lubricating oil, the car engine will become noisy due to friction.Solution: Refuel in time and maintain enough fuel. Every time you check the amount of oil in the car, you should also check whether the lubricating oil is sufficient. Two. Sensor failure Car sensors can sense various information, such as engine speed, position and temperature. When the sensor fails, it may lead to increased engine noise. Solution: The sensor needs to be changed or repaired. 3. The leakage of the exhaust pipe and silencer The exhaust pipe and the silencer are the two main components used to reduce the emission noise of diesel engines. In daily use, these parts may wear out or break, resulting in noise problems. Solution: Replace the damaged exhaust pipe and silencer. Four. Pulleys and transmission belts The problem of pulleys and transmission belts play an important role in automobile engine systems. If there is a problem with them, it may cause the engine noise to increase.Solution: Regularly check the belt and pulley for cracks, burn marks or wear, and replace them if necessary. 5. Insufficient or deteriorated engine oil plays a role in reducing friction and cooling the engine in vehicle operation. Insufficient oil or deterioration may cause the engine noise to become louder. Solution: Change the oil regularly to ensure that the quality of the oil meets the requirements. For the above situation, the car must be overhauled and maintained in time to avoid causing bigger problems. In addition, there are some other ways to help reduce engine noise. The following are several methods: 1. Regular replacement of oil and filter Regular replacement of oil and filter can ensure that the engine is running in good condition and reduce noise. Two. Installing soundproofing materials can effectively reduce engine noise. 3.Avoid high-load driving. High-load driving may cause engine noise to become louder. Therefore, avoiding high-load driving can reduce this situation. In a word, if you find that the engine noise of the car is louder, timely measures should be taken to deal with it. For those who need to replace car parts, it is recommended to go to a regular car repair shop for repair to ensure that the car can run safely. At the same time, good repair and maintenance habits can also reduce the maintenance costs and trouble of engine noise.
