Title:
SADDLE-RIDING TYPE VEHICLE
Document Type and Number:
WIPO Patent Application WO/2019/059258
Kind Code:
A1
Abstract:
This saddle-riding type vehicle (11) is provided with: a vehicle frame (12); an engine (28) suspended from the vehicle frame (12); a catalyst (43) which is disposed under the engine (28) and purifies exhaust gas discharged from the engine (28); a silencer (45) disposed downstream of the catalyst (43) in the flow direction of the exhaust gas; a downstream exhaust pipe (44) disposed downstream of the catalyst (43) in the flow direction, connected to the silencer (45), and having a smaller cross-section than the catalyst (43); and a connection pipe (47) which is sandwiched between the downstream exhaust pipe (44) and the catalyst (43) and has an expansion chamber (55) having a larger cross-section than the catalyst (43). Thus, a saddle-riding type vehicle is provided in which the length of the exhaust pipe is sufficient for each cylinder, and which can sufficiently reduce the exhaust pressure downstream of the catalyst.
