摘要： 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.

摘要： The invention relates to a method for detecting the start of combustion in a cyclically operating internal combustion engine in which a fuel/air mixture is ignited by means of a corona discharge, wherein, to generate the corona discharge, an electrical resonant circuit is excited, in which an ignition electrode that is electrically insulated with respect to combustion chamber walls constitutes a capacitor together with the combustion chamber walls, and, to identify the start of combustion, an electrical variable of the resonant circuit is evaluated. The position of an extremum is evaluated, the extremum occurring in the course of the electrical variable after ignition of the corona discharge and before extinguishment thereof, or the course of the electrical variable is compared with a reference course, wherein a threshold value is predefined and fuel combustion is concluded on the basis of a deviation by more than the threshold value.

摘要： A method for knock detection in an internal combustion engine in which a fuel/air mixture is ignited by means of a corona discharge. To generate the corona discharge, an electrical resonant circuit is excited, in which an ignition electrode that is electrically insulated with respect to combustion chamber walls constitutes a capacitor together with the combustion chamber walls. For knock detection, an electrical variable of the resonant circuit is measured and the course thereof is evaluated. The course of the electrical variable is checked to determine whether it has a local extremum after the start of the fuel combustion.
