Do CDI ignition systems use mechanical points for controlling the ignition event?

CDI, or Capacitor Discharge Ignition systems, operate based on electronic components rather than relying on mechanical points to control the ignition event. The CDI system uses a capacitor to store electrical energy and then releases it to the ignition coil at the appropriate moment to generate a high-voltage spark for the ignition of the fuel-air mixture in the engine.

The absence of mechanical points differentiates CDI systems from traditional ignition systems, which often use mechanical points and a distributor to manage timing. This electronic approach allows for more precise control over ignition timing, enhanced reliability, and reduced maintenance since there are fewer moving parts that can wear out. Therefore, it is correct to state that CDI systems do not utilize mechanical points in their operation.
