Capacitor discharge ignition (CDI) or thyristor ignition is a type of automotive electronic ignition system which is widely used in outboard motors, motorcycles, lawn mowers, chainsaws, small engines, gas turbine-powered aircraft, and some cars.
So-called capacitive discharge ignition systems create coil voltages with much shorter rise times and can produce a spark across spark plugs with some fouling. Electronic ignition systems replace some or all of the components the Delco ignition system with solid state and/or optical devices and provide both higher voltages and more reliable ...
MSD Ignition was the first company in the world to experiment with Multiple Spark Discharge for the ignition system of internal combustion engines in 1970. The idea was first proposed by a group of engineers working on the White Sands Missile Range in southern New Mexico. The engineers worked for the research and development company Autotronic ...

The most famous aftermarket electronic ignition which debuted in 1965, was the Delta Mark 10 capacitive discharge ignition, which was sold assembled or as a kit. The Fiat Dino was the first production car to come standard with EI in 1968, followed by the Jaguar XJ Series 1 [ 9 ] in 1971, Chrysler (after a 1971 trial) in 1973 and by Ford and GM ...
Saab Direct Ignition is a capacitor discharge ignition developed by Saab Automobile, then known as Saab-Scania, and Mecel AB during the 1980s. It was first shown in 1985 and put into series production in the Saab 9000 in 1988.
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 ...
