Abstract
An adaptive ignition controller for an internal combustion engine provides for engine operation at substantially peak thermal efficiency for all engine operating conditions by controlling the ignition advance angle initiating combustion to a crankshaft angle before top dead center that establishes the burn center at a predetermined crankshaft angle, the burn center being determined by monitoring the value of an indicator function PV.nu. during the combustion period.
