Delco ignition system

The Delco ignition system, also known as the Kettering ignition system, is a type of Inductive discharge ignition system invented by Charles F. Kettering. It was first sold commercially on the 1910 Cadillac and was manufactured by Delco. Over time, this system was used extensively by all automobile and truck manufacturers until the development of capacitor discharge ignition (electronic ignition) systems in the 1960s. Delco ignition systems were also used by a number of early aircraft engines.
