摘要:
A method for controlling an internal combustion engine includes monitoring an engine operating state and selectively operating the engine in a multiple-injection, multiple-ignition combustion mode comprising three injection events based upon the engine operating state. The selective operation includes controlling a first injection during a recompression period of the combustion cycle, controlling a second injection event effective to establish a homogeneous fuel charge prior to a main combustion, and controlling a third injection late in the compression phase of the combustion cycle.
