TL;DR: In this article, a control system for a direct-injection spark-ignition internal combustion engine is presented, which includes a first control section for switchably controlling a combustion mode between a homogeneous combustion mode and a stratified stoichiometric combustion mode.
Abstract: A control system for a direct-injection spark-ignition internal combustion engine is provided which includes a first control section for switchably controlling a combustion mode between a homogeneous combustion mode and a stratified stoichiometric combustion mode, and a second control section for advancing, at a time of switching from the homogeneous combustion mode to the stratified stoichiometric combustion mode, an ignition timing by an amount for offsetting a variation of torque simultaneously with switching of the combustion mode, gradually retarding the ignition timing after the switching of the combustion mode, and after the ignition timing has retarded a predetermined amount, retarding a compression stroke fuel injection timing in the stratified combustion mode while retarding the ignition timing further. A control method is also provided.
