Description

Technical Field

[0001] The utility model relates to the technical field of automobile exhaust pipelines, in particular to an environmentally friendly automobile exhaust pipeline. Background Art

[0002] At present, with the continuous development of my country's economy, motor vehicles have become very popular. Almost every family now owns a car. When people choose a car, they not only pay attention to the appearance of the car, but also pay great attention to the safety, stability and environmental awareness of the car. In recent years, the number of urban motor vehicles has increased rapidly, and the accompanying traffic noise pollution has become increasingly prominent. Surveys show that motor vehicle noise accounts for 85.5% of urban traffic noise. With the development of automobile energy conservation and emission reduction, cars are required to reduce noise and save energy consumption. The main noise of a car comes from the exhaust system of the car, that is, the noise of automobile exhaust emissions. In order to reduce the noise of automobile exhaust emissions and meet the requirements of automobile environmental protection, a muffler is usually set on the exhaust pipe of the car. The muffler is an important measure to eliminate aerodynamic noise and prevent dynamic noise. It is a heavy component in the automobile exhaust system, which is conducive to reducing noise pollution during the driving process of the car. It is made using the principle of sound wave superposition interference. The traditional automobile exhaust system achieves noise reduction by installing a muffler, but the installation and sealing effect of the muffler is not good. Therefore, an environmentally friendly automobile exhaust pipeline is proposed. Utility Model Content
