Canister arrangement structure for straddle-type vehicles

Abstract

The filter tank configuration structure of cross -riding vehicles (69) has: engine (10A), which has a crankshaft box (11); the exhaust pipe (14A), the front of the engine (10A) in the crankshaft box (11) from the engine (10A) (11) of the crankshaft box (11)After extending below the front direction, pass the engine (10A) through the engine (10A); and the filter tank (70), the evaporation fuel generated in the fuel tank (8), of which, the filter tank (70) is in the crankshaft box (11) of the crankshaft box (11).The front is configured between the engine (10A) and the exhaust pipe (14A).

Description

technical field [0001] The present invention relates to a canister arrangement structure of a straddle type vehicle. Background technique [0002] Conventionally, as a canister arrangement structure for a straddle-type vehicle, there is, for example, a structure disclosed in Japanese Patent Application Laid-Open No. 5-86994. This structure is such that the exhaust pipe of the engine faces rearward along one side of the cylinder, and the canister is arranged in front of the crankcase on the side opposite to the exhaust pipe. In Japanese Patent Application Laid-Open No. 5-86994, by disposing the canister at the opposite position away from the exhaust pipe, it is possible to prevent the conduit connected to the canister from interfering with the exhaust pipe or being affected by heat. [0003] However, when the exhaust pipe extends downward from the front of the engine in front of the crankcase and passes below the engine, it may be difficult to secure a space for the canister...

Problems solved by technology

[0003] However, when the exhaust pipe extends downward from the front of the engine in front of the crankcase and passes below the engine, it may be difficult to secure a space for the canister to be arranged in front of the crankcase.
