ABSTRACT:
A target torque map is determined by an engine rotation number and an acceleration pedal opening degree. Plural control constant groups are provided to correspond the respective target torque map. A fuel precedent control is carried out by the plural constant control groups. By detecting an engine combustion condition, under a worse combustion condition a transfer to a higher torque side is carried out with a time function according to a complementary control of the control constant group. In a direct injection system engine, a controlling apparatus in which a stratified combustion and a homogeneous stoichiometric combustion are easily and stably.
