Abstract
A method for adjusting fuel injection timing in an internal combustion engine including a cylinder and configured to operate multiple fuel injections in the cylinder per combustion cycle includes monitoring in-cylinder pressure through a first combustion cycle, determining actual combustion phasing metrics based upon the in-cylinder pressure, monitoring a baseline fuel injection timing comprising a first injection timing and a second injection timing, providing expected combustion phasing metrics based upon the baseline fuel injection timing, comparing the actual combustion phasing metrics to the expected combustion phasing metrics, and adjusting the baseline fuel injection timing in a second combustion cycle based upon the comparing.
