ABSTRACT:
A mode control system for a direct injection spark ignition engine is controlled to operate in either homogeneous air/fuel modes or stratified air/fuel modes. When transitioning from homogeneous to stratified mode, the throttle is used to adjust manifold pressure to a level where it is possible to operate in a stratified mode with a torque equal to that of the homogeneous model. When transitioning from a stratified to a homogeneous model, the throttle is used to adjust manifold pressure to a level where it is possible to operate in a homogeneous model with a torque equal to that of the stratified mode. During the transition, other engine operating conditions are used to assist in controlling engine torque.
