When a condition for the prediction of the occurrence transient knocking has held, that is, when a cooling water temperature &thetas;w is not less than a threshold value &thetas;wref and an intake air flow Qa is not less than a threshold value Qaref and a deviation of the intake air flow &Dgr;Qa is not less than a threshold value &Dgr;Qaref (S550 to S570), ignition is performed with timing on the delay angle side compared to timing FT1 by a delay angle amount α that tends to decrease as an amount increase coefficient Kf increases (S600 to S680). Because of this, it is possible to suppress the occurrence of knocking without causing the ignition timing to be delayed more than necessary. As a result of this, it is also possible to suppress the worsening of drivability.
