ABSTRACT:
An engine control system for an internal combustion engine of a type having a stratified combustion mode and a homogeneous combustion mode comprises a controller for controlling a swirl flow in the engine with a swirl control valve. The controller effects a changeover of a swirl control mode of the swirl control valve from a weak swirl mode to a strong swirl mode immediately in response to a changeover request signal before an actual changeover of a combustion control mode from the homogeneous combustion mode to the stratified combustion mode. In the case of a changeover from the stratified mode to the homogeneous mode, the controller effects a changeover of the swirl control mode from the strong swirl mode to the weak swirl mode in response to an actual changeover of the combustion control mode, with a delay after the changeover request signal.
