Abstract:
A combination speed limiter and transmission interlock system for an engine-transmission power train, the engine having a coil that outputs an ignition pulse and an igniter that ignites an air-fuel mixture, the transmission being interconnected to a switch that indicates one of a neutral position of the transmission and an in-gear position of the transmission, the combination speed limiter and transmission interlock system comprising:an ignition control circuit, connected in circuit with the coil, that prevents the igniter from igniting the air-fuel mixture; a speed control circuit, connected in circuit with the ignition control circuit, that causes the ignition control circuit to prevent the igniter from igniting the air-fuel mixture when the engine exceeds a limit speed; and a start control circuit, connected in circuit with the switch and the ignition control circuit, that causes the ignition control circuit to prevent the igniter from igniting the air-fuel mixture when the transmission switch indicates the in-gear position of the transmission during starting of the engine.
