Distributorless coil ignition system (DIS)

Advancements in the area of ignition from conventional coil ignition (CI) and transistor ignition (TI) to electronic ignition (EI) and to fully electronic ignition (FI) have happened since 1982. While the high-voltage distribution is still mechanical for EI, it is purely electronic in FI. The latter thus contains no parts susceptible to wear. The spark advance happens electronically, taking into account different variables such as the engine speed.

With the components of this equipment set the basics of the DIS ignition can be investigated. DIS means 'distributerless ignition system' and thus describes a system without rotatinbg distributor.
