Title: Internal combustion engine control method

Patent ·
OSTI ID:1632491

A method for controlling an internal combustion engine having a plurality of cylinders including a first cylinder and one or more remaining cylinders includes selecting a desired auto-ignition dwell for a first combustion cycle for the first cylinder of the plurality of cylinders. A first fuel mass is provided to the first cylinder which is combusted during the first combustion cycle. An actual auto-ignition dwell for the first combustion cycle which results from the first fuel mass is determined and a dwell error is calculated. The dwell error is used to determine a second fuel mass which provided to the first cylinder and which is combusted during the second combustion cycle.
