The ignition control requirements of an internal combustion petrol engine are reviewed and the benefits of accurate ignition control are discussed. A design for a microprocessor-based open-loop ignition controller is described and the experimental results obtained with this controller presented. Various means of achieving further improvements are suggested, including a closed-loop controller for optimum ignition timing under all conditions of engine wear. This strategy uses peak cylinder pressure angle as the feedback signal on which the adaptive control is based.
