A method for controlling mode transitions, such as from stratified to homogeneous
mode, in a direct injection engine adjusts an intake manifold outlet control device,
such as a cam timing, to rapidly control cylinder fresh charge despite manifold
dynamics. In addition, a coordinated change between an intake manifold inlet control
device, for example a throttle, and the outlet control device is used to achieve
the rapid cylinder fresh charge control. In this way, engine torque disturbances
during the mode transition are eliminated, even when cylinder air/fuel ratio is
changed from one cylinder event to the next.
