Abstract

An apparatus for producing spark ignition of an internal combustion engine in which a capacitor (C1) is connected in a resonant circuit with the primary (1a) of an ignition coil (1). An arrangement is provided to charge the capacitor (C1), and a thyristor (SCR) is connected in the circuit so that when fired an oscillatory current flows in the circuit so as to induce in the secondary (1b) of the coil (1) an oscillatory high voltage for producing spark ignition. The charging current to the capacitor (C1) is inhibited during the current discharge so as to maximise the period that the thyristor (SCR) can be held conductive without becoming locked in a permanently conductive condition.
