Abstract
An ignition system for an internal combustion engine having a transistor switch means connected across a primary winding of an ignition coil wherein a base current input terminal of the transistor switch means is connected through a coil to an igniting exciter coil to supply a base current through the coil to the base current input terminal thereby decreasing a power loss at the interruption of a primary current flowing through an ignition coil and operating a transistor in a low power loss region, so that a high voltage may be induced across a secondary winding of an ignition coil.
