[0002] At present, the automobile manufacturing industry has gradually developed into an important pillar industry in my country. Among them, the driving power of automobiles is mainly generated by the combustion of oil-gas mixed fuel in the cylinder of the engine. In addition, in the automobile exhaust system, because the engine will produce a loud sound when it discharges the high-temperature and high-pressure gas after combustion, which will cause a certain degree of noise pollution, so a muffler is usually installed in the automobile exhaust system to reduce the exhaust noise of the automobile engine. To improve the user experience, some car mufflers can only handle a single type of noise. The noise reduction material filled in the car muffler will be worn out during use. After a period of use, the effective noise reduction effect can no longer be achieved and needs to be replaced. car muffler, a waste of resources and costs
