The Capacitor Discharge Ignition (CDI) system is an electronic ignition system used in internal combustion engines. An ignition system provides a high-voltage spark in the engine’s cylinders to ignite the air-fuel mixture. The CDI system uses high-voltage capacitor discharge current output to fire the spark plug.
The SCR firing initiates the capacitor discharge which generates an alternative current. The SCR conducts during all the positive phases of the discharge current while the diode D acts for the negative parts. Figure 3. Discharge current through the circuit
„The Multi-Spark Capacitor Discharge Ignition system is housed in a diecast box which provides adequate heatsinking for the four Mosfets.“
The capacitor between 0.47 and 2μF is used firstly, to store the charge from the HV supply. During the second phase of the ignition cycle the capacitor is discharged through the ignition circuit. The switch transfers the energy stored in the capacitor to the primary of the ignition coil. This function is carried out by a SCR or a triac.
Third, CDIs used an SCR (silicon controlled rectifier) to discharge the dump capacitor and these are typically rated for an AC supply frequency of 400Hz maximum. While the SCRs will operate at higher frequencies, it is an unspecified condition and it ultimately also sets a limit on the maximum spark rate.
Components rated to operate up to 100°C. Twenty or so years ago, Capacitor Discharge Ignition (CDI) was the acknowledged solution for automotive enthusiasts wanting a high energy ignition circuit. CDI gave a really hot spark which would fire virtually any spark plug no matter how fouled or grotty it was.
