<p>An ECU (20) of an internal combustion engine (1) estimates an anticipated air amount in response to a demand for the internal combustion engine (1) and causes an injector (12) to inject an initial amount of fuel determined in accordance with the anticipated air amount so that an air-fuel ratio of a mixture in a combustion chamber (3) is lower than a target value, and thereafter, calculates an amount of intake air aspired into the combustion chamber (3) based on a in-cylinder pressure in the combustion chamber (3) at a given timing during a compression stroke and before ignition, and causes the injector (12) to inject a correction amount of fuel determined based on the calculated amount of the intake air and the initial amount of the fuel so that the air-fuel ratio of the mixture in the combustion chamber (3) corresponds to the target value.</p> |
