Abstract

The invention provides an automobile muffler. The automobile muffler comprises a front sealing cover, a muffler main body and a rear sealing cover. A sound muffling cavity is formed between the front sealing cover and the rear sealing cover. A first separation plate and a second separation plate are arranged in the sound muffling cavity. A gas inlet pipe is arranged between the front sealing cover and the first separation plate. An exhaust pipe is arranged between the second separation plate and the rear sealing cover. The front sealing cover, the first separation plate, the second separation plate and the rear sealing cover are each provided with a through hole coaxially. One end of the gas inlet pipe is installed on the front sealing cover. The other end of the gas inlet pipe is installed on the first separation plate. One end of the exhaust pipe is installed on the second separation plate. The other end of the exhaust pipe is installed on the rear sealing cover. The space between the gas inlet pipe and a muffler wall is filled with filler. The space between the exhaust pipe and the muffler wall is filled with filler. A sound muffling chamber is formed between the first separation plate and the second separation plate. According to the automobile muffler, noise of an exhaust system of an automobile can be effectively muffled, and vibration of the automobile is reduced. Meanwhile, the service life is very long, the strength is very good, and the requirement of light weight of the automobile is met.
