Abstract
A saddle-riding type vehicle includes a driver's seat on which an occupant taking a driving posture sits, a fuel tank disposed in front of the driver's seat and extending in a front-rear direction and a canister formed into a long-length shape that defines a longitudinal direction of the canister, fuel vapors generated in the fuel tank being brought into the canister and adsorbed and held by an adsorbent provided in the canister. The canister is disposed under the fuel tank with the longitudinal direction aligned with the front-rear direction and is entirely covered by the fuel tank in vehicle side view.
Claims16
A saddle-riding type vehicle comprising:
- a driver's seat on which an occupant taking a driving posture sits;
- a fuel tank disposed in front of the driver's seat and extending in a front-rear direction and having a fuel vapor outlet at a bottom of the fuel tank;
- a canister formed into an elongated shape that defines a longitudinal axis of the canister, fuel vapors generated in the fuel tank being brought into the canister and adsorbed and held by an adsorbent provided in the canister;
- and
- a fuel vapor discharge pipe extending through the fuel tank and connecting a vapor phase part of the fuel tank to the fuel vapor outlet,
- wherein a bottom portion of the fuel tank includes a raised portion extending along a longitudinal axis of the vehicle at a center of the fuel tank with respect to a vehicle width, the raised portion being configured to extend above an axially-extending portion of a vehicle body frame extending along the longitudinal axis of the vehicle,
- wherein the canister is disposed under the bottom portion of the fuel tank with the longitudinal axis of the canister aligned with the front-rear direction and is entirely covered by the fuel tank in a vehicle side view, and
- wherein the canister is lower than an upper surface of the raised portion in the vehicle side view, has a length entirely overlapped by a length of the raised portion, and is lower than an upper surface of the axially-extending portion of the vehicle body frame where the canister is located.
A saddle-riding type vehicle comprising:
- a fuel tank including a tank outer plate made of metal and a tank bottom plate made of metal;
- and
- a canister in which fuel vapors generated in the fuel tank are brought and adsorbed and held by an adsorbent provided in the canister,
- wherein the tank outer plate has an approximately U-shaped cross-sectional shape orthogonal to the front-rear direction and opened downward,
- wherein the tank bottom plate closes a lower opening of the tank outer plate,
- wherein the tank outer plate and the tank bottom plate are welded to each other along respective lower peripheries,
- wherein the canister is entirely covered by the tank outer plate in the side view of the vehicle,
- wherein a bottom portion of the fuel tank includes a raised portion extending along a longitudinal axis of the vehicle at a center of the fuel tank with respect to a vehicle width, the raised portion being configured to extend above an axially-extending portion of a vehicle body frame extending along the longitudinal axis of the vehicle,
- wherein the canister is lower than an upper surface of the raised portion in the side view of the vehicle, has a length entirely overlapped by a length of the raised portion, and is lower than an upper surface of the axially-extending portion of the vehicle body frame where the canister is located.
