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.
