HS code mapping for duty optimization

Tuguan engine is HS code mapping for duty optimizationloud: why is the noise interference serious? Tuguan is a very popular SUV, which is deeply loved by consumers. However, Tuguan owners generally reported that the noise of the vehicle engine is particularly loud, which seriously affects the driving and riding experience. Why is the engine of Tuguan so loud? This is a question worth exploring. First of all, you need to understand the working principle of the car engine. The engine needs to burn mixed gas to generate energy and push the vehicle forward, and the process will produce noise. If the noise of the engine is not effectively controlled, its noise will be transmitted to the compartment through the chassis, etc., causing interference and discomfort, and seriously affecting the safety of driving and the pleasure of riding.So, what are the reasons for the engine sound of Tuguan? First of all, the engine power of Tuguan is relatively high. The engine of Tuguan usually adopts a 2.0T four-cylinder engine with high power and torque output, which will produce more exhaust sound and mechanical noise. Compared with low-power engines, high-power engines are generally noisy. Secondly, Tuguan's exhaust system not only shows a loud sound, but also shows a low-frequency and powerful sound. Tuguan's exhaust system usually consists of an exhaust head, several exhaust pipes and a silencer. This system is relatively simple to design, so the noise will be louder. Moreover, the Tuguan exhaust system adopts a low-frequency tone design, which increases the sound of the subwoofer of the engine and further increases the noise. In addition, the insulation effect of the Tuguan's body and engine compartment is relatively poor.Many car owners reported that when driving at high speed, the engine sound is significantly increased, especially when the engine is under heavy driving load. This is because the sound insulation of the car body is poor, and the soundproofing measures of the cabin are insufficient, which makes the noise of the vehicle transmitted to the compartment more obvious. Finally, the engine of Tiguan itself has technical problems, which is also one of the reasons for the serious noise interference. Some owners of Tuguan reported that when the vehicle is driving at low speed, there will be a "dada gyro" sound caused by gravity, and the running sound of the engine will be louder. This sound may be caused by certain faults, such as bearing damage, gear wear, etc., which will cause the engine noise to become louder. In summary, there are many reasons for the loud noise of the Tuguan engine, which may be due to high engine power, too simple exhaust system, poor sound insulation of the body and engine compartment, and technical problems with the engine itself.In order to solve this problem, we can start from the following aspects: First, repair and maintain the engine, regularly replace the oil and filter, repair faults, and ensure the normal operation of the engine and all parts around the engine; Second, improve and upgrade the exhaust system, use high-quality materials and reasonable use The silencer can effectively control the noise; III. Improve the sound insulation effect of the body and engine, install soundproofing materials, and improve the noise reduction function of the car body. Through the above means, combined with the maintenance and debugging and subjective feelings of the owner of Tuguan, the problem of loud noise of the Tuguan engine can be gradually solved, making this brand, which is already deeply loved by people, more perfect. In a word, to improve the safety, comfort and driving experience of the car, in addition to taking into account various performance requirements, special attention should be paid to noise control, because it is related to the physical health, mood and mental health of the driver and passenger.In the process of solving the problem of Tuguan engine sound, it is necessary to fully consider the feelings of drivers and passengers to provide a high-quality driving experience.
