EVAPORATIVE FUEL TREATMENT DEVICE FOR INTERNAL COMBUSTION ENGINE

PROBLEM TO BE SOLVED: To provide an evaporative fuel treatment device for an internal combustion engine, certainly discharging vapor accumulated in a canister and also stabilizing control over an air-fuel ratio. SOLUTION: This evaporative fuel treatment device 50 for the internal combustion engine includes a fuel tank 33, the canister 51 collecting the evaporative fuel V generated in the fuel tank 33, a fuel supply pipe 32 feeding raw material fuel F in the fuel tank 33 to a delivery pipe 31, and an evaporative fuel communication pipe 52 supplying the evaporative fuel V in the fuel tank 33 to the canister 51. The evaporative fuel treatment device includes a liquefying means 53 composed of a liquefying tank 55 pressurizing and liquefying the evaporative fuel V desorbed from the canister 51 and an evaporative fuel lead-out pipe 56 sucking out the evaporative fuel V collected with the canister 51 to the liquefying tank 55, and a liquefied fuel supply pipe 54 feeding the liquefied fuel L liquefied with the liquefying means 53 to the delivery pipe 31.
