Global supply chain risk assessment

Analysis of the reason for the high noise of the automobile engine Automobile is Global supply chain risk assessmentone of the most commonly used means of transportation in modern society, and engine noise is a common problem in the use of automobiles. Sometimes, engine noise even becomes a headache for drivers and passengers in the car. In this article, we will discuss the reasons for the high noise of automobile engines and how to reduce noise. 1. Engine wear or aging The wear or aging of the engine is one of the main factors causing high noise. When the engine is working, friction will inevitably occur, withWith the extension of the use time, the wear caused by friction will usually become more and more serious, resulting in increased engine noise. This is also one of the reasons why older vehicles are usually noisier than new cars. In addition, long-term neglect or neglect of maintenance needs will also lead to excessive engine wear, resulting in more noise. Two. Exhaust system failure The exhaust system is composed of exhaust pipes, silencers and exhaust gas purifiers, etc. The failure of any of these components may lead to increased engine noise. For example, leakage of the exhaust pipe or damage to the silencer will cause the gas discharged from the engine to make a clear sound. The materials in the exhaust gas purifier may also become less durable due to excessive use, which will also lead to increased noise. 3. Transmission system failure The transmission system includes components such as transmission, clutch and transmission shaft. If it fails or is damaged, it will also lead to increased engine noise.For example, if the gears of the transmission are damaged or worn, they will make noise. Similarly, the clutch panc is also one of the common sources of noise, especially when the transmission is in gear. Four. Wheel and tire problems. The reason for the increase in engine noise may also be related to wheel and tire problems. In fact, if your tires are old or worn too much, or use a rougher tire surface, you may hear more noise from road noise and body vibration during driving, which will also increase the noise level of the entire vehicle. How to reduce engine noise? The above factors are the main reasons for the high noise of car engines, so how can we reduce this noise? First of all, it is best to inspect and maintain the vehicle before use, especially for old vehicles, routine inspection and maintenance will be one of the necessary conditions to reduce engine noise.Secondly, choose the right tire style and specifications to reduce its friction with the ground to reduce the noise level of the whole vehicle. In addition, it should be noted that when buying a vehicle, if you want a relatively low-noise car, it is also very important to choose a low-noise exhaust system, better sound insulation and a comfortable car seat. To sum up, there are many reasons for the high noise of car engines, and there are also various ways to reduce noise. When choosing a car model and maintaining a vehicle, you should pay more attention to choosing a suitable vehicle and a way to use it to avoid problems and inconveniences caused by engine noise.
