Abstract

A scooter-type motorcycle is provided with a storage box that stores an article disposed under a seat, a unit swing-type engine unit having an engine and a power transmission device integrated with each other and mounted at a vehicle lower portion below the article storage box, a fuel tank disposed at the vehicle lower portion in front of the engine unit, and further provided with a canister, that temporarily collects a fuel evaporative gas generated in the fuel tank and supplies the fuel evaporative gas to a cylinder assembly constituting a portion of the engine, the canister being arranged in front of the cylinder assembly and above a rear portion of the fuel tank to thereby control the fuel evaporative gas.

Description

technical field [0001] The present invention relates to a scooter having a canister that temporarily collects fuel evaporated gas generated in a fuel tank and can supply the gas to an engine side, and enables control of fuel evaporated gas. Background technique [0002] Conventionally, in the fuel tank of a motorcycle, the stored fuel may be vaporized and stagnated in the upper part of the fuel tank as fuel evaporated gas. There is known such a fuel vapor control technology: In order to prevent the fuel vapor gas from leaking into the atmosphere when the engine is stopped, the fuel vapor gas is introduced into the canister for temporary collection, and the fuel vapor gas in the canister is drained when the engine is started. supplied to the engine side. [0003] As an example of such a device, Patent Document 1 discloses such a small motorcycle: a storage box is arranged under the seat, an engine unit is arranged below the storage box, and an engine unit is installed in the...
