Abstract
A method and apparatus for controlling the ignition timing in an internal combustion engine. The angular position of peak cylinder pressure is measured and to the extent such angular position deviates from a preselected set point, the time of spark ignition is advanced or retarded to restore the position of peak cylinder pressure to the set point.
