Abstract
A method and apparatus are provided to control combustion in a multi-cylinder internal combustion engine operating in a controlled auto-ignition mode with minimum combustion phasing error using a least amount of fuel reforming. This comprises monitoring combustion in each cylinder, and determining a target combustion phasing. Fuel delivery to each cylinder is selectively controlled effective to achieve the target combustion phasing, and, effective to achieve the target combustion phasing further comprises controlling the fuel delivery effective to equilibrate combustion phasing of the cylinders.
