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.
The contact breaker is operated by an engine-driven cam.On an engine with a distributor, the contact breaker can be found beneath the distributor cap.The position of the contact breaker is set so that it opens (and hence generates a spark) at exactly the optimum moment to ignite the fuel/air mixture.
The discharge capacitor within the CD ignition had the ability to provide a powerful spark in excess of 4 times the spark power of the Kettering system using the same coil, with the exception that spark energy could be maintained at high rpm unlike the Kettering system.
Later patent applications to the US Patent Office make reference to the "Kettering ignition system". This type of ignition system was used on automobiles, trucks, lawn mowers, tractors, chainsaws, and other gasoline-powered machinery with great success for many decades until the development of capacitive-discharge ignition systems.
A variation coil-on-plug ignition has each coil handle two plugs, on cylinders which are 360 degrees out of phase (and therefore reach top dead center (TDC) at the same time); in the four-cycle engine this means that one plug will be sparking during the end of the exhaust stroke while the other fires at the usual time, a so-called "wasted spark ...
The ignition coils for these can be combined into a single casing (a coil pack) and located away from the spark plugs; however it is increasingly common for coil-on-plug systems to be used, whereby the individual ignition coils are small units attached directly to the top of each spark plug. An advantage of coil-on-plug systems is that in the ...
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.
High energy ignition, also known as H.E.I., is an electronic ignition system designed by the Delco-Remy Division of General Motors. It was used on all GM vehicles, at least in the North American market, from 1975 through the mid-1980s.
