Noise-proof motorbike exhaust pipe with large discharge capacity function

Abstract

The invention discloses a noise-proof motorbike exhaust pipe with a large discharge capacity function. The pipe comprises an air inlet pipe body. One end of the air inlet pipe body is fixedly connected with an air outlet pipe body, and an inner cavity of the air inlet pipe body communicates with an inner cavity of the air outlet pipe body. An exhausting assisting device is arranged in the inner cavity of the air inlet pipe body. The inner wall of the air outlet pipe body is fixedly connected with the surface of a gas gathering pipe body. One end of the gas gathering pipe body is fixedly connected with the surface of a gas dispersing pipe body. Gas dispersing holes are formed in the surface of the gas dispersing pipe body. According to the noise-proof motorbike exhaust pipe with the large discharge capacity function, waste gas in the air inlet pipe body can blow fan blades on the exhausting assisting device when being exhausted, the fan blades are rotated, suction force is produced, thedischarge capacity of the exhaust pipe is increased, and accordingly, the phenomenon that waste gas in the exhaust pipe of a motorbike fails to be exhausted in time is avoided; by arranging the gas gathering pipe body and the gas dispersing pipe body, all the waste gas enters the gas dispersing pipe body, and then the waste gas is exhausted out of the gas dispersing pipe body; and since the gas dispersing holes are formed in the surface of the gas dispersing pipe body, when the waste gas in the exhaust pipe is to burst out, the waste gas is exhausted into the air outlet pipe body through thegas dispersing holes, pressure produced by the waste gas in the gas dispersing pipe body is reduced, and the phenomenon that noise is produced when the waste gas bursts out of the gas dispersing pipebody is avoided.

Description

technical field [0001] The invention relates to the technical field of exhaust pipes, in particular to an anti-noise motorcycle exhaust pipe with a large displacement function. Background technique [0002] The exhaust pipe is a part of the engine exhaust system. The exhaust system mainly includes the exhaust manifold, the exhaust pipe and the muffler. Generally, the three-stage catalytic converter that controls the emission of engine pollutants is also installed in the exhaust system. The exhaust The pipe generally includes a front exhaust pipe and a rear exhaust pipe. [0003] At present, most of the exhaust pipes of motorcycles use a single tubular form to discharge exhaust gas. After this exhaust pipe is installed on some motorcycles with large displacement, when the speed of the motorcycle reaches a certain level, the exhaust pipe will increase. Fuel consumption, so the combustion of gasoline in the motorcycle engine will produce a large amount of exhaust gas, and if t...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a noise-proof motorcycle exhaust pipe with large displacement function, which can make the exhaust gas in the exhaust pipe be discharged into the air outlet pipe through the air diffuser hole when the exhaust gas in the exhaust pipe is about to be sprayed out, so as to reduce the exhaust gas emission. The advantage of the pressure generated by the exhaust gas in the trachea solves the problem that the exhaust pipe of the motorcycle not only cannot discharge the exhaust gas in the exhaust pipe in time, but also causes a large noise even when the exhaust gas is ejected from the exhaust pipe
