Tändningsreglering av en kolvförbränningsmotor med gnisttändning

摘要

The present invention relates to a method of a reciprocating combustion engine with at least two cylinders. Primary voltage is taken from a voltage supply and transformed to secondary voltage suitable for ignition purposes. The invention is based on an adaptive control method and means of a combustion engine ignition system. The spark plugs with the highest secondary voltage demand are recognised by continuously measuring the actual secondary voltage demand. The ignition timing is advanced (503) for individual cylinders before the secondary voltage demand reaches a level where misfire can occur.
