Abstract
A control apparatus for an internal combustion engine according to the invention obtains a first index that indicates the amount of fuel adhering to the wall surface of an intake passage, using intake valve timing; obtains a correction value that reduces the first index, using exhaust valve timing and the intake valve timing; and calculates a second index that indicates the amount of fuel adhering to the wall surface of the intake passage, using the correction value. The control apparatus controls the amount of fuel to be injected based on at least one of the first index and the second index.
