The Delco ignition system, also known as the Kettering ignition system, points and condenser ignition or breaker point ignition, is a type of inductive discharge ignition system invented by Charles F. Kettering. It was first sold commercially on the 1912 Cadillac [1] and was manufactured by Delco.
An improved ignition system was invented by Charles Kettering at Delco in the United States and introduced in Cadillac's 1912 cars. [2] The Kettering ignition system consisted of a single ignition coil, breaker points, a capacitor (to prevent the points from arcing at break) and a distributor (to direct the electricity from the ignition coil to ...
Kettering was hired directly out of school to head the research laboratory at National Cash Register (later known as NCR Corporation). Kettering invented an easy credit approval system, a precursor to today's credit cards, and the electric cash register in 1906, which made ringing up sales physically much easier for sales clerks.
The name "Delco" came from the "Dayton Engineering Laboratories Co.", founded in Dayton, Ohio, by Charles Kettering and Edward A. Deeds in 1909. [1] Delco was responsible for several innovations in automobile electric systems, including the first reliable battery ignition system and the first practical automobile self-starter.
These effects can largely be overcome using electronic ignition systems, where the contact breakers are retrofitted by a magnetic (Hall effect) or optical sensor device. However, because of their simplicity, and since contact breaker points gradually degrade instead of catastrophically failing, they are still used on aircraft engines.
Charles Kettering, co-founder of Delco, was head of research at General Motors for 27 years. Herbert C. Harrison was President of Harrison Radiator until his death in 1927. [5] William C. Durant lost control of GM for the final time in 1920. United Motors Service would become a fully integrated division of General Motors in 1944. [6]
Kettering found an overhead valve (OHV) set-up to be the most viable engine design. Kettering's OHV engine was an advanced design for the time period. [3] The design was four-cylindered and called for a straight engine configuration. This type of engine allowed for better cooling on the top end of the engine, as well as between cylinders.
