摘要： PROBLEM TO BE SOLVED: To provide an evaporated fuel processing device mounted on a vehicle which sufficiently suppresses emission of evaporated fuel generated inside an intake passage into the atmosphere after stopping an internal combustion engine.
SOLUTION: The device is provided with a canister 14 for adsorbing evaporated fuel generated in a fuel tank 10. The canister 14 communicates to an intake passage 26 through the medium of a purge passage 22. The purge passage 22 is provided with a purge VSV 24. A throttle valve 30 is arranged in the intake passage 26. While closing a throttle valve 30 for a set period after stopping an internal combustion engine, a purge control valve 24 is opened so as to make the canister 14 absorb evaporated fuel in the intake passage 26.

摘要： PROBLEM TO BE SOLVED: To prevent an air/fuel ratio from being leaned due to the adhesion of a fuel to a wall surface in an air/fuel control device of an internal combustion engine. SOLUTION: As the parameter indicating the degree of the shortage of the fuel adhered to the wall surface, the deviation ΔFPG between a purge correction factor FPG and a smooth value FPGSM provided by smoothening the purge correction factor FPG in the direction of time is provided (S100 to S104). An asynchronous injection time ASYFPG is determined according to the value of the deviation ΔFPG (S110). The shortage of the fuel adhered to the wall surface is eliminated by performing fuel injection by the asynchronous injection separately from the normal fuel injection according to the determined asynchronous injection time ASYFPG.
