Title: Ignition apparatus

Abstract: An ignition apparatus for a gasoline engine of independent cylinder type with low-voltage wiring has no distributor, and a CDI (Capacitor Discharge Ignitor) is employed to improve the ignition characteristic of lean mixture. In order to lengthen a discharge time of the ignition apparatus of CDI type, the primary winding of a transformer in series with a switching element is connected in parallel to a capacitor, the ends of which are connected to a DC power supply. The switching element includes an IGBT and a diode connected in parallel to each other.
