To stable supply gasified fuel not recondensed to an internal combustion engine under a warm-up process, in a gasified fuel supply device supplying gasified fuel to the internal combustion engine in cold start.
An air suction port 34 of a canister 32 for gasifying fuel is selectively connected to either a hot air suction pipe or a cool air suction port 36 by a vacuum switching valve (VSV) 30. The hot air suction pipe 28 sucks hot air heated by exhaust heat. Fuel necessary for generating the gasified fuel to be supplied in the warm-up process is supplied to the inside of the canister 32 by a fuel injection valve 40 for gasification. In the warm-up process, gasified fuel not to be recondensed is supplied to the internal combustion engine 10, by purging the fuel with cool air. After the warm-up, a weight component of the fuel remaining in the canister 32 is purged with hot air.
