Abstract

The ignition system consists of a free-running ignition final stage, a miniature induction coil, a static and/or dynamic determination of the ignition angle, and a power supply. The ignition final stage ensures that the ignition current is an alternating current and that the ignition energy is fed to the spark plugs in a current-controlled manner. The ignition point is determined by reading the ignition angle. The electrical supply to the entire ignition final stage and additional consumers in a motor vehicle is through a power supply that converts the current and voltage.
