Auspuffsystem für ein fahrzeug

Abstract

The invention discloses a vehicle discharging device, which connects a silencer (25) in a discharging device of a vehicle of a discharge pipe (23) which is extended from a motor (6), a catalytic convertor (30) is prepared in the middle way of the discharge pipe (23) and / or the silencer (25), in the catalytic convertor (30), a leading-in pipe (55) and a discharge pipe (57) which lead to a catalytic room (53) to discharge gas is centralized to allocate on one end side of the catalytic room. Thereby forming in the pattern of seeking distribution diversification of the catalytic convertor, and the invention can accelerate catalytic in a cold machine status to be activation.

Description

technical field [0001] The present invention relates to vehicle emission devices equipped with catalytic converters. Background technique [0002] Generally, there is known an exhaust system for a motorcycle in which a muffler is connected to an exhaust pipe extending from an engine (for example, refer to Patent Document 1). As such a vehicle exhaust device, a type in which the rear portion of the exhaust pipe is introduced into the inside of the muffler and the diameter of the rear portion of the exhaust pipe is enlarged rearwardly has been proposed in order to improve engine performance. In the above-mentioned conventional discharge device, generally, the catalytic converter is equipped with a catalyst chamber, and the introduction pipe of the exhaust gas leading to the catalyst chamber is connected to one side of the catalyst chamber, and the discharge pipe is connected to the other end of the catalyst chamber. side. [0003] (Patent Document 1) JP-A-6-10659 [0004] H...
