Engine gas exhausting device

Abstract

The invention provides an engine gas exhausting device. The engine gas exhausting device comprises an exhaust pipe connected with an engine, and the exhaust pipe is connected with a silencing pipe ina detachable mode. The silencing pipe is provided with two end plates, and the two end plates are connected with an upper shell and a lower shell in a detachable mode. A plurality of gas outlet holesare formed in the position, located between the two end plates, of the silencing pipe. Two turntables are rotationally connected to the part, located between the two end plates, of the silencing pipe.A plurality of glass fiber mounting bases are connected to each turntable. A plurality of glass fibers are arranged between the front glass fiber mounting base and the rear glass fiber mounting base.Gear rings are arranged on the turntables, and a fixing pipe is arranged on each end plate. A plurality of fixed teeth are arranged at the end, located on the inner side of each end plate, of the corresponding fixing pipe. A rotating shaft is rotationally connected in each fixing pipe and provided with a gear. A plurality of movable teeth are arranged on each gear. Reset devices are arranged between the rotating shafts and the end plates. The engine gas exhausting device has the advantages that the whole silencer does not need to be replaced, and the use and maintenance cost of a vehicle is reduced.

Description

technical field [0001] The invention relates to the technical field of engine equipment, in particular to an engine exhaust device. Background technique [0002] When the engine is working, exhaust gas will be discharged continuously. Generally, the engine exhaust device includes an exhaust pipe connected to the engine. The exhaust pipe is connected with a muffler, and the muffler is detachably installed on the vehicle. Equipment such as a three-way catalytic converter is also installed on the exhaust pipe, and the exhaust gas produced by the engine enters the muffler through the exhaust pipe and is finally discharged. The existing muffler includes a muffler pipe, the muffler pipe is connected with a shell by welding, the shell is filled with glass fibers, and a number of air outlets are opened on the muffler pipe, through which the waste gas enters the shell. The formed cavity consumes energy under the action of glass fiber and plays the role of noise reduction. [0003] ...

AI Technical Summary

Problems solved by technology

[0003] The above technical solution has the following disadvantages: after long-term use, the glass fiber filled in the shell will break, and then enter the muffler pipe through the air outlet, and the light one will be ejected out of the muffler pipe with the exhaust gas, resulting in the reduction of the glass fiber filled in the shell , reduce the noise reduction effect; severe cases block the noise reduction pipe, resulting in poor engine exhaust and affecting the normal operation of the engine

[0004] However, since the muffler pipe and the shell are welded together, the glass fiber filled in the shell cannot be replaced separately, but the entire muffler can only be replaced, which is cumbersome to operate, and the cost of vehicle use and maintenance is relatively high
