Abstract:
A control system for an internal combustion engine comprising:an internal combustion engine having a combustion chamber; an injector for supplying fuel to said combustion chamber to produce an air fuel mixture therein; an ignition plug provided for said combustion chamber to ignite said air fuel mixture; and a controller configured to: detect a need to convert a combustion mode from one of a homogeneous mode and stratified mode to the other of the homogenous mode and stratified mode, adjust a parameter that affects engine torque to adjust the engine torque while operating in said one of the homogeneous and stratified mode to reduce a torque difference due to mode conversion which would otherwise occur if the mode conversion would take place without such a torque adjustment, and convert the combustion mode to the other of the homogeneous mode and stratified mode after having completed the torque adjustment operation.
