Breakerless ignition system for a multicylinder internal combustion engine

Claim 1

A breakless ignition system for a multicylinder internal combustion engine comprising a plurality of ignition circuits each including an ignition coil and solid state switching means to control said ignition coil so as to allow a primary current to flow through said ignition coil and to cut off said primary current so that a high voltage is established across said ignition coil and a control circuit to control each of said solid state switching means of said ignition circuits, said control circuit associated with a signal generator rotating in time with a multicylinder internal combustion engine for generating signals to operate said control circuit, the improvement wherein said control circuit comprises a corresponding number of flip-flop circuits to that of said ignition circuits, said flip-flop circuits each having one of the output terminals connected to the control terminal of the corresponding solid state switching means so that it interrupts said solid state switching means with one of the adjacent flip-flop circuits signaling the other flip-flop circuit to cause conduction of the corresponding solid state switching means with said other flip-flop circuit when said one flip-flop circuit interrupts the corresponding solid state switching means, said signal generator including a corresponding number of signal coils to that of said ignition circuits, which control said flip-flop circuits.
