Abstract
A method for control of spark ignition in a spark-ignited internal combustion engine that includes an ignition plug and generates plasma to ignite an air-fuel mixture, where the plasma is caused by a reaction between a product resulting from spark discharge generated by a high voltage applied via an ignition coil connected to the ignition plug and an electric field generated in a combustion chamber by an electric generation means via the ignition plug, the method including generating the electric field by a positive pulsating current. Thus, the method allows a spark-ignited internal combustion engine to promote expansion of combustion after ignition.
