Contactless ignition system

Claim 1

AN IGNITION SYSTEM FOR AN INTERNAL COMBUSTION ENGINE, COMPRISING IN COMBINATION, A POWER SUPPLY, AT LEAST ONE SPARK DISCHARGE DEVICE, AN ENERGY STORAGE DEVICE FOR STORING ELECTRICAL ENERGY FROM SAID POWER SUPPLY, AND A TRIGGERING MEANS FOR CAUSING THE TIMED INTERMITTENT DISCHARGE OF ENERGY FROM SAID ENERGY STORAGE DEVICE TO SAID SPARK DISCHARGE DEVICE, SAID TRIGGERING MEANS COMPRISING A CONTROLLED OSCILLATOR OPERABLY CONNECTED TO SAID POWER SUPPLY AND TO SAID ENERGY STORAGE DEVICE, SAID OSCILLATOR INCLUDING A TRANSISTOR HAVING A CONTROL ELECTRODE, A PAIR OF MAGNETICALLY COUPLED COILS OPERABLY CONNECTED TO SAID CONTROL ELECTRODE, A TIMING DISC DRIVEN BY SAID ENGINE AND HAVING EQUALLY SPACED PORTIONS OF EFFECTIVE HIGH PERMEABILITY SEPARATED BY AREAS OF EFFECTIVE LOW PERMEABILITY WHEREBY ROTATION OF SAID DISC WILL SERIALLY PASS SAID PORTIONS OF EFFECTIVE HIGH PERMEABILITY PAST SAID PAIR OF COILS TO CAUSE PROGRAMMED VARIATIONS IN THEIR MAGNETIC COUPLING WHEREBY SAID PROGRAMMED VARIATIONS IN SAID MAGNETIC COUPLING CAUSE PROGRAMMED VARIATIONS IN THE OUTPUT FREQUENCY OF SAID OSCILLATOR, MEANS OPERATIVELY CONNECTED TO SAID OSCILLATOR AND RESPONSIVE TO SAID PROGRAMMED VARIATIONS IN OUTPUT FREQUENCY TO VARY THE AMPLITUDE OF SAID OUTPUT DURING SUCCESSIVE PERIODS IN TIMED PROPORTION TO ENGINE SPEED, AND MEANS TO DETECT SAID SUCCESSIVE PERIODS OF OUTPUT AND EFFECTIVE TO PRODUCE TIMED VOLTAGE PULSES AT A FREQUENCY PROPORTIONAL TO ENGINE SPEED, SAID DETECTOR MEANS OPERATIVELY CONNECTED TO SAID ENERGY STORAGE DEVICE TO CAUSE SAID INTERMITTENT DISCHARE OF ENERGY FROM SAID ENERGY STORAGE DEVICE TO SAID SPARK DEVICE IN TIMED PROPORTION TO ENGINE SPEED.
