Abstract
A method for operating an internal combustion engine includes determining an actual combustion heat release during ongoing engine operation, calculating an expected combustion heat release corresponding to engine operation associated with the actual combustion heat release during ongoing engine operation, determining a difference between the actual combustion heat release and the expected combustion heat release, and operating the internal combustion engine in a homogeneous-charge compression-ignition combustion mode to achieve a preferred combustion phasing during each combustion cycle in response to the difference between the actual combustion heat release and the expected combustion heat release.
