Abstract
Abstract Energy provided by two circuits each of which has inductive and capacitive components which provide initial conditions for the ignition firing cycle, makes possible high modulated power components of the system for delivery to a high voltage distributor. Such conventional distributor sequences the igniter firing.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
84 words
A multiple double energy modulation ignition system, comprising the combination of: an ignition transformer having a primary winding and a secondary winding; a first circuit composed of the primary winding and a first capacitor in series therewith; a second circuit composed of a second capacitor and an inductor in series therewith, said first and second capacitors having a common electrical junction; and means electrically connected to the common junction for providing intermittent electrical connection between said junction and an electrical return of the system.
Claim 2
Dependent Claim
84 words
A multiple double energy modulation ignition system, comprising the combination of: an ignition transformer having a primary winding and a secondary winding; a first circuit composed of the primary winding and a first capacitor in series therewith; a second circuit composed of a second capacitor and an inductor in series therewith, said first and second capacitors having a common electrical junction; and means electrically connected to the common junction for providing intermittent electrical connection between said junction and an electrical return of the system.
Claim 3
Dependent Claim
43 words
The invention as stated in claim 1, wherein said means comprises an electrically conductive member driven during said operative mode and having electrically insulative inserts regularly positioned at its periphery within the confines thereof and an electrical contactor in cooperation with said periphery.
Claim 4
Dependent Claim
34 words
The invention as stated in claim 1, wherein said means comprises an electrically insulative cam driven during said operative mode and a pair of contactors intermittently actuated by said cam during said operative mode.
Claim 5
Dependent Claim
27 words
