CONSTRUCTION OF EXHAUSTION PIPE FOR AUTOMOBILE

摘要

PURPOSE: An exhaust pipe structure for a vehicle is provided to improve the torque and fuel efficiency of an engine in low and middle speed ranges by reducing exhaust interference. CONSTITUTION: An exhaust pipe structure for a vehicle comprises left and right exhaust pipes(20,30) and a junction part(40). The left and right exhaust pipes are respectively connected to left and right manifolds(10b,10a). The left side exhaust pipe is extended to the rear of the engine. The right exhaust pipe comprises a straight part(31) formed toward the front of the engine and a bent part(32) which is arranged in parallel to a right exhaust plate. The end of the bent part of the right exhaust pipe and the end of the left exhaust pipe are connected and joined in the junction part. The junction part is connected to a catalytic converter. The bent part of the right exhaust pipe and the left exhaust pipe contact each other on the exterior surface, where the surface contact parts of the right and left exhaust pipes are in the shape of semi-circular pipes facing each other.
