<p>While an "injection time representative crank angle", which is a timing for obtaining a "representative swirl velocity" according to an operation state of an engine is specified, a "spray representative position", which is a specified position in spray for obtaining a "representative swirl velocity" is specified. A "representative swirl velocity" at the specified "injection time representative crank angle" and in the specified "spray representative position", and an "actual representative swirl velocity", which is obtained by performing temperature correction on the "representative swirl velocity" are calculated. A "target representative swirl velocity" according to an operation state of the engine is calculated, and an opening degree of a swirl control valve is adjusted such that the "actual representative swirl velocity" matches the "target representative swirl velocity".</p> |
