Abstract
A bipolar activated magnetic pulse timer (50, Q.sub.a, Q.sub.b) is shown for an ignition system (Q1, Q2, Qn, Qp, 80, 90, 40, 40a) of a fuel burning engine. Such system includes a pair of semiconductor switches (Q.sub.a, Q.sub.b) wherein the output circuits of such switches are serially connected. A magnetic pulse timer (50) having an output winding (53) is connected to the input circuits of such switches. Such switches and timer intermittently activate a variety of ignition circuits.
Claims6
