Abstract
A method for controlling the ignition point of a fuel/air mixture in an internal combustion engine by at least one corona discharge starting from an electrode, wherein at least one of the corona discharges is ignited at a crankshaft angle between 400° and 200° before the top dead center, with which the power stroke starts, by applying an ignition voltage to the electrode(s), and the energy input of the corona discharge or of the corona discharges is controlled by adapting the burn time of the corona discharge and the strength of the ignition voltage. The fuel/air mixture ignites at a crankshaft angle between 30° and 5° before the top dead center, with which the power stroke starts, and 50% of the fuel of the fuel/air mixture is combusted at a crankshaft angle between 6° and 10° after the top dead center point, with which the power stroke starts.
