ABSTRACT:
When fuel vapor flows to an intake passage from a canister, the amount of fuel injected to an internal combustion engine is corrected to suppress fluctuation of the air-fuel ratio in the engine due to the fuel vapor. An EGR mechanism variably sets the EGR rate. When the pressure in a fuel tank is greater than or equal to a predetermined value, a tank sealing system releases gas containing fuel vapor from the fuel tank to the canister on condition that fuel vapor is flowing to the intake passage from the canister. A controller controls the EGR mechanism to reduce the EGR rate when gas is released from the fuel tank to the canister. Therefore, combustion is stabilized even if EGR is executed when gas in the fuel tank is released.
