A CDI, or Capacitor Discharged Ignition is a system that is linked to the ignition of some petrol engine driven vehicles.Its purpose is to store an electrical charge that is discharged through the ignition coil and thus increases the power to the spark plug/s for a very powerful, high-energy spark.This prevents fouling of the spark plug/s.A CDI can be disconnected in some vehicles and the engine would still run, but with a less powerful spark to the spark plug/s.his prevents fouling of the spark plug/s.

The main advantage of the CDI is simply to make settlement of trades and custody of stocks easier for foreign securities. The broker doesnât need to make any arrangements for this in the stockâs home country, but can simply rely on the CREST infrastructure in the same way they would for a UK stock.lthough the structure of the CDI means that the underlying stock is held in the name of CREST rather than in your name being on the register of shareholders, the same is true for most share ownership today.
