Abstract
A compression ignition engine () has a control system () for processing data, one or more combustion chambers (), and fuel injectors () for injecting fuel into the chambers (). The control system () controls fueling using a result of the processing of certain data, such as engine speed and engine load, to select one of three fueling modes (HCCI, HCCI+CD, CD) for operating the engine (). When the result of the processing selects the HCCI mode, the engine () is fueled to cause homogeneous-charge compression-ignition (HCCI) combustion in all combustion chambers (). When the result of the processing selects the HCCI+CD mode, the engine () is fueled to cause HCCI combustion in some chambers () and CD (conventional diesel) combustion in the remaining chambers (). When the result of the processing selects the CD mode, the engine () is fueled to cause CD combustion in all chambers ().
