Abstract
The utility model discloses an automobile muffler, which is composed of a shell body, an end cover, a gas inlet pipe and a gas outlet pipe; a sound absorption pipe is arranged inside the shell body; and the middle part of the sound absorption pipe takes a spiral shape. A plurality of hollow sound absorption chambers are arranged on the surface of the sound absorption pipe wall and inside the pipe wall; and the sound absorption chambers are communicated with the porous channels among the surrounding adjacent sound absorption chambers. A lining board with the same structure as the sound absorption pipe wall is padded inside the shell body. The utility model has simple structure, small exhaust resistance to an automobile engine, wider noise elimination frequency band, as well as good noise elimination effect. Experiments show that compared with the automobile muffler in the prior art, the utility model can reduce noise by 7-10db; when the input wind source speed is 22.9 meters/second, the output wind speed of the automobile muffler in the prior art is up to 16.9 meters/second, while that of the utility model reaches 17.9 meters/second. Due to the exhaust resistance reduction of the automobile engine, the effective output power of the automobile engine is correspondingly improved.
Description
Technical field:
The utility model relates to a kind of mobile muffler, relates in particular to the mobile muffler in a kind of automobile exhaust path.
Technical background:
At present, the mobile muffler that is commercially available generally is made up of housing, end cap, suction tude, ram's horns, steam outlet pipe etc.What have also is provided with dividing plate in described housing, the housing inner chamber is divided into several noise elimination cavities.Contrast proof by experiment, the defective that above-mentioned mobile muffler exists is: structural design is undesirable, and easily the exhaust to motor car engine produces big resistance, has reduced the effective output of motor; Also depositing the defective that the noise elimination frequency range is narrow, the noise elimination effect is relatively poor simultaneously.
Summary of the invention:
The purpose of this utility model provides a kind of mobile muffler, and this baffler is little to the exhaust resistance of motor car engine, noise elimination frequency range broad, eliminate the noise effective.
The purpose of this utility model is finished by following proposal:
A kind of mobile muffler is made up of housing, end cap, suction tude, steam outlet pipe etc., also is provided with absorbing duct in described housing, and an end of described absorbing duct is communicated with suction tude, and the other end is communicated with steam outlet pipe, and the middle part of described absorbing duct twist.
As a kind of preferred version of such scheme, there be duct to be connected between the surface of described absorbing duct tube wall and the inner absorption chamber that is provided with a plurality of hollows thereof, absorption chamber and its adjacent absorption chamber on every side.
As a kind of preferred version of such scheme, in described housing, be lined with liner plate with absorbing duct tube wall same structure.
The utility model has the advantages that: simple in structure, little to the exhaust resistance of motor car engine, noise elimination frequency range broad, eliminate the noise effective.The results showed: the utility model can reduce noise 7-10db than the mobile muffler of prior art; Under the situation of input wind regime wind speed 22.9 meter per seconds, mobile muffler output wind speed 16.9 meter per seconds of prior art, the utility model output wind speed 17.9 meter per seconds.Owing to reduced exhaust resistance, the corresponding effective output that improves motor car engine to motor car engine.
