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.
Delco Electronics Corporation was the automotive electronics design and manufacturing subsidiary of General Motors based in Kokomo, Indiana, that manufactured Delco Automobile radios and other electric products found in GM cars. In 1972, General Motors merged it with the AC Electronics division and it continued to operate as part of the Delco ...
Ignition was by Delco coil and breaker points, with the distributor at the end of the generator/starter unit. [5] With a 2.875 in (73.0 mm) bore and a 5 in (127.0 mm) stroke, [6] the engine had a displacement of 260 cu in (4.3 L).
A predecessor system called "Unitized Ignition" was optional on 1972 and 1973 Pontiacs. [citation needed] Most—but not all—HEI systems have the ignition coil mounted in the distributor cap. A control module and magnetic pickup are mounted in the distributor, in place of a conventional ignition system's breaker points and condenser.
Inductive discharge ignition systems were developed in the 19th century as a means to ignite the air–fuel mixture in the combustion chamber of internal combustion engines. The first versions were low tension coils , then low-tension and in turn high-tension magnetos , which were offered as a more effective alternative to the older-design hot ...
Kettering's key insight lay in devising an electrical system performing the three functions it still serves in modern cars: starter; producer of spark for ignition; and source of current for lighting. [15] Leland ordered 12,000 self-starters for his 1912 models; Delco had to then transition from its research and development activities to ...
Breaker arm with contact points at the left. The pivot is on the right and the cam follower is in the middle of the breaker arm. A contact breaker (or "points") is a type of electrical switch, found in the ignition systems of spark-ignition internal combustion engines. The switch is automatically operated by a cam driven by the engine.
