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 4):
The controller for an internal combustion engine according to  claim 1 , wherein\n the internal combustion engine includes a valve property variable device that variably sets a closing timing of the intake valve, the calculating process includes calculating the returned air amount based on intake pressure and a parameter indicating a valve property of the intake valve determining the closing timing, and the calculated returned air amount increases as the closing timing is retarded and also increases as the intake pressure is increased.
