摘要（英）：

A muffler comprises a muffler body. The muffler body comprises a first interface part, a first transition part, a cylinder part, a second transition part, and a second interface part. The first interface part comprises a first interface port and a first channel. The first transition part comprises a first transition channel. The cylinder part comprises a cylinder channel. The second transition part has a second transition channel. The second interface part comprises a second interface port and a second channel. The first interface port, the first channel, the first transition channel, the cylinder channel, the second transition channel, the second channel and the second interface port are communicated with each other. The through-flow area of the cylinder part is greater than the through-flow area of the first interface part; the through-flow area of the cylinder part is greater than the through-flow area of the second interface part; the muffler comprises at least one filtering component; and the filtering component is arranged in the cylinder channel.
