Abstract:
1. An internal combustion engine operable in homogeneous charge compression ignition mode, comprising: an engine body with a plurality of combustion cylinders formed therein; a combustion chamber formed in each combustion cylinder for combustion of a fuel and charge-air mixture; combustion parameter determining means for determining values of one or more combustion parameters of combustion in said combustion chamber, said combustion parameters characterizing the combustion event and reflecting at least changes in rates of said combustion from cycle to cycle; engine operation control means for adjusting one or more engine operating parameters to change one or more combustion parameter values for subsequent combustion events; and combustion control parameter control means, programmed to adjust combustion control parameter values responsive to said changes in said combustion parameter values, or in response to said engine operating parameter adjustments, and to limit or counteract changes in said combustion parameter values while one or more engine operating parameters are being adjusted by the engine operation control means.
