Abstract
In a control apparatus, a peak engine revolution actual value gnepk during a present post-startup of an engine is calculated. A post-startup peak engine revolution target value tnepk is read from a map. An intake air flow QST used for the next startup is determined by multiplying the intake air flow QST used for the present startup by the ratio between the post-startup peak engine revolution actual value gnepk and the post-startup peak engine revolution target value tnepk, that is, tnepk/gnepk. This control apparatus is therefore able to control the engine revolution during the post-startup with good precision.
