Abstract

See full text

Methods and systems are provided for integrating engine water injection technology with a CVT transmission. Responsive to a driver demand, a controller may determine whether to maintain a current water injection state or transition to an alternate water injection state based on each of the efficiency of the transition, water availability, and any engine limitations that may be incurred at the engine speed-load following the transition. To improve the net fuel economy benefit while addressing the engine limitation, the water injection state transition may be combined with a CVT adjusted engine speed-load regime, while maintaining engine power output.
