The invention discloses a silencer which comprises a barrel, an air inlet pipe and an air exhaust pipe. The air inlet pipe and the air exhaust pipe are arranged at the two ends of the barrel, separating plates are arranged inside the barrel and comprise the first separating plate, the second separating plate and the third separating plate, the barrel is sequentially divided by the separating plates into a first cavity, a second cavity, a third cavity and a fourth cavity, and a catalytic conversion carrier is arranged in the first cavity; and inner insertion pipes are arranged in the barrel andcomprises the first inner insertion pipe, the second inner insertion pipe and the third inner insertion pipe, the first inner insertion pipe penetrates the first separating plate, the second separating plate and the third separating plate, and the second inner insertion pipe and the third inner insertion pipe penetrate the second separating plate to be arranged in the second cavity and the thirdcavity. The silencer and the catalytic conversion carrier are integrated, the car internal space distribution is saved, cost is saved, and the silencer has the tail gas purification effect while the noise elimination performance is achieved.
Description
technical field [0001] The invention relates to the technical field of auto parts, in particular to a muffler and a manufacturing method thereof. Background technique [0002] With the rapid development of my country's automobile industry and the improvement of people's living standards, the number of urban automobiles is increasing day by day. However, while the rise and development of the automobile industry has brought huge economic benefits to our country, it also brings problems such as environmental pollution and noise pollution that need to be solved. [0003] Various investigations and measurement results show that urban traffic noise is the most important noise source in the urban environment at present, and reducing the noise of motor vehicles is the most important and fundamental way to reduce urban environmental noise. Therefore, the noise of automobiles as the main body of motor vehicles control becomes the key. Engine noise is the main noise source of a car, ...
