Abstract

The invention provides a catalysis silencer structure. The catalysis silencer structure comprises a hollow shell, a first end cover, a second end cover and a first partition plate, wherein the first end cover and the second end cover are arranged at the two ends of the shell respectively, and the first partition plate is arranged in the shell. A cavity between the first partition plate and the first end cover is a first cavity, and a cavity between the first partition plate and the second end cover is a second cavity. The shell is provided with an air inlet pipe communicated with the first cavity, and the first end cover is provided with an air outlet pipe communicated with the first cavity. A catalysis device communicated with the first cavity and the second cavity is arranged at one end of the first partition plate. A silencing device is arranged at the other end of the first partition plate. One end of the silencing device is communicated with the second cavity. The other end of the silencing device is fixedly connected with the air outlet pipe. The catalysis silencer structure is easy to install, meanwhile, the space occupied by a tail gas post-treatment device can be effectively reduced, and the arrangement of a whole vehicle is greatly facilitated.

Description

technical field [0001] The invention relates to the technical field of automobile exhaust systems, in particular to a catalytic muffler structure. Background technique [0002] The exhaust system of a car usually has an exhaust after-treatment device including a catalytic converter and a muffler. While reducing noise, it also converts harmful gases such as carbon monoxide, hydrocarbons and nitrogen oxides in the car exhaust through oxidation and reduction. For harmless carbon dioxide, water and nitrogen. [0003] Such as figure 1 As shown, the existing catalytic converter 11 and the muffler 12 need to be installed in the exhaust system of the automobile respectively, so that the installation process of the exhaust gas after-treatment device is relatively complicated; meanwhile, since the catalytic converter 11 and the muffler 12 are independent parts, making The space occupied by the exhaust after-treatment device in the driving direction of the vehicle is relatively large...
