PURPOSE:To improve exhaust emission, by changing a moderation coefficient when an air flow meter is in a change of opening direction, in the case of an engine which performs a fuel injection control after an input data as an intake air amount is moderated by using the predetermined moderation coefficient. CONSTITUTION:When an engine is in operation, an input data TPn of intake air amount by an air flow meter 2 is fetched to a CPU40, and when an engine speed NE by a rotary angle sensor 26 is less than the predetermined value, the engine, obtaining a difference DELTATP of the input data TPn from its preceding time data, executes a moderating process when this difference DELTATP is in a positive value. In this moderating process, the engine obtains a moderation coefficient K corresponding to the difference DELTATP by using a predetermined map, when a flag value is '0', while uses the moderation coefficient K, obtained when the preceding time flag is '0', being left as it is when the flag value is decided to be except '0'. And an intake air amount Qp is calculated in accordance with a predetermined expression by using the moderation coefficient K as obtained in the above.
