Muffler provided with double exhaust pipes

Abstract

The invention discloses a muffler provided with double exhaust pipes. The muffler comprises a casing, a first end cover, a second end cover, a first partition board, a second partition board, a third partition board, a gas inlet pipe, a left exhaust pipe, a right exhaust pipe and a plurality of guiding pipes, wherein the first end cover and the second end cover are fixed at two ends of the casing respectively; the first partition board, the second partition board and the third partition board are arranged in the casing; the gas inlet pipe is L-shaped and comprises a first pipe body parallel to an axis of the casing, a second pipe body vertical to the first pipe body as well as a first guiding pipe, a second guiding pipe and a third guiding pipe which are welded in the tail end of the first pipe body; the left exhaust pipe penetrates through and is fixed on the first partition board and the first end cover, and two ends of the left exhaust pipe are communicated with a second chamber and outside atmosphere respectively; the right exhaust pipe penetrates through and is fixed on the second partition board, the third partition board and the second end cover, and two ends of the right exhaust pipe are communicated with the second chamber and the outside atmosphere respectively. The muffler is good in noise reducing effect, meanwhile, airflow circulation is smooth, pressure loss is smaller, and exhaust back pressure can meet related requirements.

Description

technical field [0001] The invention relates to a double exhaust pipe muffler, which belongs to the technical field of engine exhaust aftertreatment. Background technique [0002] At present, automobile exhaust noise has become one of the main noise sources affecting the environment, and installing exhaust mufflers is the main method to control exhaust noise. Due to the limitation of the installation space, it is usually impossible to ensure a large enough muffler volume. In the case of a small muffler volume, in order to ensure a good muffler effect, it is usually necessary to design the interior of the muffler very complicated, resulting in an increase in the exhaust back pressure. Large, the engine power loss increases, the economy is reduced, and the reliability of the muffler is greatly reduced. Contents of the invention [0003] The purpose of the present invention is to solve the existing technical problems and provide an automobile exhaust muffler with good noise ...
