Abstract (en)
An apparatus for producing spark ignition of an internal combustion engine, comprising an ignition coil having primary and secondary windings (1a, 1b), a capacitor (c) connected to the primary winding (1a), voltage generating means (4) for receiving a supply voltage (5:12V) and arranged to charge the capacitor to a voltage greater than the supply voltage, switching means (SCR) arranged to cause the capacitor (c) to discharge through the primary winding (1a) and thereby produce in the secondary winding (1b) a voltage pulse for producing spark ignition of the engine, and control means (8) arranged to apply to the output of the secondary coil a direct current capable of sustaining a spark established by said voltage pulse.
