发明名称 EXHAUST PIPE MEMBER FOR VEHICLE
摘要 PURPOSE: An exhaust pipe member for a vehicle is provided to efficiently remove the noxious gas of a converter by keeping the temperature of the exhaust gas and to minimize the noise of the exhaust gas by using an air layer formed in a double pipe. CONSTITUTION: An exhaust pipe member(10) is prepared by fitting an outer pipe(12) to the outer circumference of an inner pipe(11). A mesh recess(13) or a protrusion is formed on the surface of the inner pipe. The exhaust pipe member is installed in between an engine and a converter of an exhaust pipe. The exhaust gas generated in the engine approaches the converter by passing through the exhaust pipe member. The noxious gas of the exhaust gas is removed by the converter. The cleaned exhaust gas is discharged. Then, the temperature of the exhaust gas is kept by the exhaust pipe member. Heat loss is minimized by an air layer(20) formed by the mesh recess and the protrusion between the inner pipe and the outer pipe. The air layer also reduces the noise due to the explosion of the exhaust gas.
