Abstract

PURPOSE:To connect or release overrevolution preventive means arbitrarily by providing a release means for control of the overrevolution preventive means. CONSTITUTION:Where frequency of a pulser coil 15 becomes more than constant in accordance as an engine revolution rises, the output end 27 of an overrevolution detection circuit 26 works on positive potential and a thyristor 20 is in conduction. A charging current by generating coils L1, L2 therefore escape by way of the thyristor 20, and a condenser 8 for ignition is prevented from being charged. A sparking plug works no more consequently, and the engine is not revved up any more. A release means 28 is provided with two release terminals 28a, 28b, which are connected to the output end 27 and the gate of the thyristor 20 respectively. From releasing the connection between the terminals 28a, 28b, the overrevolution preventive means is no more operative.
