<p>A high-frequency continuous-wave ignition system for internal combustion engines. It employs a unitary magnetic circuit in a square-wave oscillator. Starting and stopping the oscillator is controlled by a winding coupled to the magnetic circuit. A circuit including this control winding has a full-wave AC short-circuit connection for stopping the oscillator between sparking intervals. However, a predetermined half-wave path in the short circuit has a greater impedance than the other half-wave path. This acts so that the magnetic circuit is always set in a given state as the oscillator is stopped. As a result it ensures instant starting of the oscillator at the beginning of each sparking interval.</p> |
