EXHAUST DEVICE FOR ENGINE

摘要

An exhaust device 29 for an engine includes a silencer 32 connected to a downstream side of an exhaust pipe 31. The exhaust pipe 31 includes a catalyst 50 and the silencer 32 includes an expansion chamber 60. The expansion chamber 60 includes a first expansion chamber 61 and a second expansion chamber 62, which are connected to each other by a first fluid communication pipe 71. The exhaust device includes an oxygen sensor 54 for detecting an oxygen component in the exhaust gas, the oxygen sensor being disposed downstream of the catalyst 50 and facing an opening 71k of the first fluid communication pipe 71. The oxygen sensor 54 is disposed outwardly of a downstream edge 31 b of the exhaust pipe 31 when the exhaust pipe 31 is viewed along a longitudinal axis thereof.
