Abstract
The present invention relates to a method for monitoring the combustion chamber of a cyclically operating combustion engine in which an air-fuel-mixture is ignited by means of a corona discharge generated by an electrical oscillating circuit in which an ignition electrode, which is electrically isolated from the combustion chamber walls, and the combustion chamber walls form a capacitor, wherein by evaluating an electrical parameter of the oscillating circuit information about the combustion chamber is gained. The voltage exciting the oscillating circuit is reduced after the beginning of the combustion and the oscillating circuit is then excited with a reduced voltage.
