Combustion phasing control methodology in HCCI combustion
Controlling combustion in a spark-ignition direction-injection internal combustion engine includes providing an initial injected fuel mass timing and an initial spark ignition timing. A combustion phasing error is monitored and compared with each of the initial injected fuel mass timing and the initial spark ignition timing. An adjusted injected fuel mass timing and an adjusted desired spark ignition timing is determined based on the comparing for maintaining a desired combustion phasing.
