ABSTRACT:
An amount-of-air detecting time period Ti is preset based on an intake time period Tr during which intake air is actually drawn into a cylinder chamber. An intake air amount average value Qa during a time period, other than the time period Ti, between intake strokes is calculated. After confirmation that one half or more of an amount-of-air detecting time period Ti(n+1) has elapsed, an integrated value of the intake air amount is multiplied by a correcting coefficient Ka, and divided by the amount-of-air detecting time period Ti(n+1), thereby calculating an intake air amount Qin during the amount-of-air detecting time period Ti(n+1). The average value Qa of the intake air amount is subtracted from the amount Qin during the amount-of-air detecting time period Ti(n+1), thereby calculating an estimated amount Qp of intake air introduced into the cylinder chamber.
