載の燃料蒸散制御装置。[Scope of Claim for Utility Model Registration] (1) A vehicle that has a supercharger in the engine intake passage and a throttle valve downstream of the supercharger, and the fuel vapor generated from the fuel tank mounted on the vehicle is transferred to activated carbon in the canister. In the fuel evaporation control device, the fuel vapor adsorbed on the canister is purged from the activated carbon by introducing outside air, and the purge air is introduced into the intake passage for combustion. A fuel evaporation control device, characterized in that the purge control valve is connected to an intake passage near or downstream of the tutle valve, and is provided in the middle of the purge air passage to control the amount of purge air according to the amount of intake air. (2) A utility model registration characterized in that the purge control valve consists of a plurality of solenoid valves with different opening degrees provided in the purge air passage, and the amount of purge air is controlled by switching the opening and closing of these solenoid valves. A fuel evaporation control device according to claim 1.
