Abstract
A compression ignition engine () has a control system (), one or more combustion chambers (), and fuel injectors () for injecting fuel into the combustion chambers. The control system controls fueling using a result of the processing of engine speed and engine load to select a particular domain for engine operation (HCCI, HCCI+CD, or CD, —FIG.). When the processing selects HCCI, the engine is fueled to cause alternative diesel combustion (such as HCCI) in all combustion chambers. When the processing selects CD, all combustion chambers are fueled for conventional diesel combustion. When the processing selects HCCI+CD, a first group of combustion chambers are fueled for HCCI combustion and a second group for CD combustion. Each group (G, G) has its own EGR valve () and turbocharger ().
