ABSTRACT:
A system for determining a minimum ignition coil charge duration of an internal combustion engine to meet a desired level of combustion stability includes a sensor in communication with a controller. The sensor is configured to measure the ionization current of a cylinder of the internal combustion engine and output to the dwell controller. The controller is configured to determine a combustion stability criterion based upon the ionization signal and determine the minimum ignition coil charge duration based upon the combustion stability criterion.
