Abstract:
An internal combustion engine is configured to operate in a homogeneous-charge compression-ignition combustion mode. A method for operating the internal combustion engine includes determining a desired effective charge dilution for a cylinder charge for a cylinder firing event. A desired air/fuel ratio, a desired intake air mass and a desired intake oxygen are determined to achieve the desired effective charge dilution for a combustion event. The desired air/fuel ratio is adjusted based upon a difference between the desired intake oxygen and the actual intake oxygen, and engine operation is controlled to achieve the adjusted desired air/fuel ratio.
