Novel exhausting pipe of engine

Abstract

The invention discloses a novel engine exhaust pipe, comprising a drum core, an air inlet and an air outlet. The drum core is a sealed hollow cylinder structure formed by the air inlet and air outlet which extend into the drum core and a plurality of noise reducing chambers composed of a plurality of separating mesh plates; each noise reducing chamber is internally and peripherally provided with a mesh plate with meshes and noise reducing cotton; a plurality of noise reducing holes are arranged around the air inlet end extending into the hollow cylinder structure of the drum core; and the individually sealed noise reducing chamber with noise reducing cotton is arranged around the position of the noise reducing hole. The invention adopts a small quantity of separating mesh plates in the hollow cylinder structure of the drum core and a large amount of noise absorbing cotton to form a plurality of noise reducing chambers so as to efficiently realize the best noise absorbing effect on the basis of keeping unobstructed air exhaust; the unobstructed air exhaust reduces the load of the engine and causes the combustion chamber to get more sufficient air supply so as to guarantee that the air in the combustion chamber is completely combusted to best explore the power, thus realizing the effects of ultra silence, strong power and low oil consumption.

Description

technical field [0001] The invention relates to the technical field of manufacturing vehicle engine exhaust pipes, in particular to a novel engine exhaust pipe. Background technique [0002] At present, the structure of the engine exhaust pipe sold on the market is composed of the drum core and the air inlet and outlet holes connected to the drum core. The exhaust pipe diameter with a roundabout direction is arranged in the drum core and is composed of spacer mesh plates. The anechoic chamber is designed to control the sound below the sound decibels stipulated by the country. Its structure is simple, but its sound absorption effect is poor, and the exhaust gas is difficult to discharge. The exhaust inside the drum core is not smooth, which increases the load on the engine. The exhaust gas is stored in In the combustion chamber, the combustion efficiency of the combustion chamber is hindered, making it difficult to exert power, and the engine consumes high fuel.
