A capacitative discharge device is provided as part of a magneto-based ignition system for enhancing the starting performance of the ignition system for an internal combustion engine. The ignition system incorporating the invention is applicable to conventional mechanically timed magnetos, including those intended to incorporate impulse coupling or inductive vibrators as starting aids. Although the ignition system incorporating the invention is primarily intended for aerospace applications, its relative small size the light weight make it also ideal for any type of portable application.

An ignition system for providing spark energy to a spark plug of an internal combustion engine having at least one reciprocating piston, the ignition system comprising in combination: a magneto having a primary coil, a rotary magnet driven by the engine and generating energy in the primary coil having a voltage of alternating polarity and a single breaker for timing a discharge of the energy from the coil to the spark plug; a capacitor for concentrating energy from a source of energy; an output circuit for delivering the concentrated energy to the primary coil of the magneto as discrete pulses whose timing is independent of the reciprocating motion of the piston; a converter responsive to the source of energy for pumping increments of energy from the source into the capacitor at a rate of at least several thousand increments per second; and a start switch for starting the internal combustion engine that enables the converter while the engine is being started and disables the converter thereafter.
