Abstract

The invention discloses an automobile exhaust main silencer. The silencer comprises a shell in any shape, wherein a first end cover is arranged on one side of the shell, a second end cover is arrangedon the other side of the shell, partition plates are arranged inside the shell, the partition plates comprise a first partition plate, a second partition plate, a third partition plate and a fourth partition plate which are sequentially arranged inside the shell, an inner gas inlet pipe, a left inner core pipe, a left inner gas outlet pipe, a right inner core pipe and a right inner gas outlet pipe are further arranged in the shell, wherein the left inner core pipe 9 and the left inner gas outlet pipe penetrate the first partition plate and the second partition plate respectively, the right inner core pipe and the right inner gas outlet pipe penetrate the third partition plate and the fourth partition plate respectively, a gas inlet pipe support is arranged on the inner gas inlet pipe, thegas inlet pipe support is connected to the second partition plate and the third partition plate, and a second supporting rod is arranged between the first partition plate and the second partition plate. The silencer can effectively solve the problem that an existing silencer cannot effectively reduce low-frequency noise.

Description

technical field [0001] The invention relates to an automobile accessory, in particular to an automobile exhaust main muffler. Background technique [0002] There is a main exhaust muffler for automobiles. The muffler includes a housing, an inner air intake pipe, four partitions and left and right inner outlet pipes. The space of the housing is divided into five chambers by the four partitions. The inner air inlet pipe extends into the third chamber, the left inner air outlet pipe passes through four partitions from the fifth chamber and extends out of the first chamber, and the right inner air outlet pipe extends from the first chamber A fifth chamber extends through the four partitions. [0003] In the case of a large number of three-cylinder engines, the muffler of this structure has the following shortcomings during use: this muffler cannot reduce low-frequency noise very well, and there is often ear-pressing sound at low speeds in the car during subjective evaluation. ...
