Ignition system

Abstract

Abstract 1. IN AN IGNITION SYSTEM FOR SUPPLYING ELECTRICAL ENERGY TO A SPARK PLUG IN AN INTERNAL COMBUSTION ENGINE WHEN THE CONTACTS OF THE IGNITION SYSTEM ARE OPEN, SAID SYSTEM INCLUDING: A SOURCE OF DC ENERGY, CONTROLLED OSCILLATOR MEANS COUPLED TO SAID SOURCE FOR SUPPLYING OSCILLATING ELECTRICAL ENERGY IN RESPONSE TO THE DC ENERGY, SAID OSCILLATOR MEANS INCLUDING AN OUTPUT MEANS AND A CONTROLLED INPUT MEANS, TRANSFORMER MEANS INCLUDING A PRIMARY WINDING COUPLED TO THE OUTPUT MEANS OF SAID OSCILLATOR MEANS, A SECCONDARY WINDING, AND A FEEDBACK CONTROL WINDING BEING COUPLED TO THE CONTROL INPUT MEANS OF SAID OSCILLATOR MEANS, RECTIFIER MEANS COUPLED TO THE SECONDARY WINDING OF SAID TRANSFORMER FOR CONVERTING INDUCED OSCILLATING SIGNALS TO A DC SIGNAL, SAID RECTIFIER MEANS INCLUDING AN OUTPUT MEANS, ENERGY STORAGE MEANS BEING COUPLED TO THE OUTPUT MEANS OF SAID RECTIFIER MEANS FOR STORING THE DC ENERGY FROM SAID RECTIFIER MEANS, GATING MEANS BEING COUPLED TO SAID ENERGY STORAGE MEANS FOR DISCHARGING THE ENERGY STORED IN SAID ENERGY STORAGE MEANS, SAID GATING MEANS INCLUDING A GATE INPUT MEANS FOR GATING SAID GATING MEANS ON WHEN THE CONTACT POINTS OF SAID IGNITION SYSTEM ARE OPEN, AND ADJUSTABLE FEEDBACK CONTROL MEANS BEING COUPLED TO THE FEEDBACK CONTROL WINDING OF SAID TRANSFORMER MEANS AND TO THE OUTPUT MEANS OF SAID RECTIFIER MEANS FOR VARYING THE AMOUNT OF ENERGY TO THE CONTROLLED OSCILLATOR MEANS AND FOR SELECTING THE ENERGY LEVEL FROM SAID OSCILLATOR MEANS TO SAID TRANSFORMER MEANS.
