Abstract:
A controller for an internal combustion engine includes a processing circuit configured to execute a calculating process that calculates a returned air amount and an operating process that operates a fuel injection valve so that an air-fuel ratio of a mixture that is burned in a combustion chamber is controlled to a target value. The operating process includes under a condition in which the returned air amount is increased, having the fuel injection valve inject fuel increased in amount from a constant fuel amount, which is an amount of fuel injected when the returned air amount is unchanged, and under a condition in which the returned air amount is decreased, having the fuel injection valve inject fuel decreased in amount from the constant fuel amount.

Claim (Index 8):
A method for controlling an internal combustion engine, wherein the internal combustion engine includes a fuel injection valve that injects fuel to supply the fuel into a combustion chamber, an intake passage connected to the combustion chamber, and an intake valve that opens and closes the intake passage, and the internal combustion engine is configured to allow a closing timing of the intake valve to be retarded from a bottom dead center timing, the method comprising:\n calculating a returned air amount, which is an amount of air that flows into the combustion chamber and returns to the intake passage before the intake valve closes; and operating the fuel injection valve so that an air-fuel ratio of a mixture that is burned in the combustion chamber is controlled to a target value, wherein the operating the fuel injection valve includes under a condition in which the returned air amount is increased, having the fuel injection valve inject fuel increased in amount from a constant fuel amount, wherein the constant fuel amount is an amount of fuel injected when the returned air amount is unchanged, and under a condition in which the returned air amount is decreased, having the fuel injection valve inject fuel decreased in amount from the constant fuel amount.
