This ignition system is based on the principle of energy storage in the ignition coil inductor. Here, the energy is output by a direct voltage transformer, prestored in a capacitor C5 and then fed to the ignition coil inductor L by means of a thyristor which is controlled by the breaker contact. A strong and enduring ignition spark is induced during the repeated exchange of electrical and magnetic energy between capacitor C5 and L of the ignition coil which now follows. C5.U<2> DIVIDED 2 = L.I<2> DIVIDED 2 A further oscillatory circuit extends the spark firing period. The said circuit consists of C6 and also of the ignition coil inductor L and oscillates with the residual energy of the ignition coil. C6 at the same time forms the R.C wiring for the thyristor in conjunction with the output resistance of the transformer. The problem of blocking the thyristor again after firing was solved by deactivating the transformer for a time > oscillation period T. In motor vehicles with a spark ignition engine, a fuel saving of approximately 10% is achieved. And the strong ignition spark also provides possibilities of using totally different types of fuel. An electrical circuit diagram (8) which is enclosed with the application clarifies the function of the capacitor ignition system.
