Abstract

The invention relates to a purification type automobile silencer which comprises a shell, wherein the shell is provided with an air inlet pipe and an air outlet pipe; the air inlet pipe comprises an S-shaped air inlet elbow and a straight air inlet pipe; the straight air inlet pipe is partitioned into a first straight air inlet pipe and a second straight air inlet pipe by a partition board; the number of silencing holes in the second straight air inlet pipe is twice of that of silencing holes in the first straight air inlet pipe; the air outlet pipe comprises an S-shaped air outlet elbow and a straight air outlet pipe; at least two layers of filter screens are arranged in the straight air outlet pipe; and a solid catalyst is filled between the two layers of filter screens. The purification type automobile silencer improves the silencing and noise reduction effects to enable the wavelength range of noise elimination to be wider and the frequency band to be wider, improves the comfort of a finished automobile and has a better automobile emission purification function to greatly reduce pollution of city atmosphere caused by automobile exhaust.

Description

technical field [0001] The invention relates to the technical field of vehicle parts and components, in particular to a purifying automobile muffler. Background technique [0002] The muffler is a device that allows airflow to pass through, but can prevent or reduce sound transmission, and is an important measure to eliminate aerodynamic noise. The muffler can block the propagation of sound waves and allow airflow to pass through, which is an effective tool for noise control. [0003] Existing mufflers at the rear of automobiles do not have a good effect on exhaust gas treatment and noise reduction, and air pollution is becoming more and more serious. Therefore, those skilled in the art need to provide a kind of purification type automobile muffler, which can not only improve the performance of the muffler. Excellent noise reduction effect, at the same time, it can purify exhaust gas and improve air quality. Contents of the invention [0004] The object of the present in...
