録請求の範囲第１項記載の燃料蒸散制御装置。[Scope of Claim for Utility Model Registration] (1) A vehicle that has a turbocharger in the engine intake passage and a throttle valve downstream of the turbocharger, which is a vehicle that uses fuel vapor generated from a fuel tank mounted on the vehicle to
In addition to adsorbing it to the activated carbon in the canister,
In the fuel evaporation control device, the fuel vapor adsorbed in the first canister is purged from the activated carbon by introducing outside air, and the purge air is introduced into the intake passage and combusted, the fuel tank being separate from the first canister. A second canister is provided, which communicates with the fuel tank when refueling the fuel tank, and adsorbs fuel vapor generated from the fuel tank to activated carbon inside, and the first and second canisters are connected to each other by purge air having purge control valves. A fuel evaporation control device, characterized in that the purge air passage is connected to an intake passage on the upstream side of the supercharger and an intake passage on the downstream side of the throttle valve via a switching means. (2) The switching means is a switching valve that introduces purge air into the downstream side of the throttle valve when the pressure is negative, and introduces purge air into the upstream side of the supercharger when the pressure is positive. A fuel evaporation control device according to claim 1 of the utility model registration claim.
