ABSTRACT:
An evaporative fuel controller for an internal combustion engine to prevent blow-off of fuel and/or outflow of emissions immediately after fuel is fed into a fuel tank, and to prevent a large quantity of evaporative fuel from flowing into a canister during engine operation. The controller includes a filler tube having a filler passage therein; a check valve for closing the filler passage immediately after the supply of fuel to the fuel tank; a refueling vapor control valve disposed on the fuel tank and communicating with the evaporation passage; a tank-side communication passage for communicating the refueling vapor control valve with the filler passage upstream of the check valve; a first communication passage for communicating the tank-side communication passage and the canister with one another; a first two-way check valve positioned in the first communication passage; a fuel cut valve located on the fuel tank; a second communication passage for communicating the fuel cut valve and the canister with one another; a second two-way check valve disposed in the second communication passage; a third communication passage bypassing the second two-way check valve and communicating with the second communication passage; and a two-way solenoid valve provided in the third communication passage.
