Gas-exhausting silencer of internal combustion engine

Abstract

The invention discloses a gas-exhausting silencer of an internal combustion engine. The gas-exhausting silencer comprises a housing, wherein three sleeves which are parallel to one another are arranged inside the housing; the two ends of the three sleeves communicate by two four-way parts; the other connectors of the two four-way parts are separately connected to a gas inlet tube and a gas outlet tube; one end of the gas inlet tube and one end of the gas outlet tube penetrate through the housing and extend to the outer part of the housing; and the housing is formed by combining six silencing plates. The gas-exhausting silencer of the internal combustion engine is simple in structure and is reasonable in design; the housing of the silencer is formed by combining the silencing plates, so that good silencing effect is achieved; spiral breather tubes are arranged, so that a contact area between sound waves and tube walls is increased, and therefore, silencing effect also can be improved; a cooling liquid between each outer sleeve and the corresponding spiral breather tube further can be used for cooling gas, so that noises generated by exhausting high-temperature gas and gas are prevented from generating pollution on environment, and therefore, living environment of people is effectively improved.

Description

technical field [0001] The invention relates to the technical field of internal combustion engines, in particular to an exhaust muffler for internal combustion engines. Background technique [0002] An internal combustion engine is a kind of power machinery, which is a heat engine that directly converts the heat energy released by burning fuel inside the machine into power. The combustion of fuel inside the internal combustion engine will produce a large amount of exhaust gas, which will generate a lot of noise when it is discharged through the exhaust pipe. However, the exhaust end of the exhaust pipe of the existing internal combustion engine is not equipped with a silencer, which will cause noise pollution. It affects people's quality of life, so we propose an internal combustion engine exhaust silencer. Contents of the invention [0003] The object of the present invention is to provide an internal combustion engine exhaust muffler to solve the problems raised in the ...
