    Abstract: Disclosed is a method for controlling the spark ignition in an Otto engine, of the type including an ignition voltage-generating ignition system with a spark plug electrode fixedly arranged in the combustion chamber of the engine and with an earth electrode co-operating movably therewith and joined fixedly to the engine piston in question. For the purpose of producing a controlled ignition moment in such engines the ignition moment is controlled so as to occur later and with shorter sparking distance when the engine load increases from light load to whole load. At the same time, the ignition voltage necessary for spark formation is controlled so as to vary within relatively narrow limits over essentially the whole load range.
