Abstract

The invention discloses a tail gas heating compartment square silencer for a commercial vehicle. The silencer comprises a shell, a front end cover and a rear end cover. The silencer is characterized in that the head and the tail of the shell are provided with the front end cover and the rear end cover correspondingly, the portions, inside the shell, on the inner sides of the front end cover and the rear end cover are each provided with a set of net plates, the space between the front end cover and the corresponding net plates and the space between the rear end cover and the corresponding net plates are filled with glass fiber, and the center line position in the shell is provided with a front partition plate and a rear partition plate. The advantage that a resistant exhaust silencer has a good silencing effect on medium and low frequency noise is kept, the removal effect on high frequency noise is achieved through repeated airflow steering and multiple air through holes, and the whistling noise of an engine supercharge is well removed. An upper exhaust pipe is used for exhausting gas upwards, the function of heating a compartment is achieved, downward exhaust is used for a compartment which does not need to be heated, and heating can be carried out or not.

Description

technical field [0001] The invention relates to an engine exhaust muffler, in particular to a muffler for the exhaust gas heating compartment of a commercial vehicle. Background technique [0002] At present, the existing engine exhaust muffler mainly adopts the resistant exhaust muffler structure of pipe cross-section expansion and cross-section contraction. Due to the change of acoustic reactance at the sudden change of the section of the sound wave, part of the sound wave is reflected back to the sound source without passing through the muffler. The outlet, so as to achieve the purpose of noise reduction. This resistant exhaust muffler has a certain effect on high, medium and low frequency noise silencing. And for the compartment that needs antifreeze protection, the exhaust gas is discharged downwards and has just caused the loss of heat energy. Contents of the invention [0003] The object of the present invention is to provide a muffler for the exhaust gas heating ...
