ABSTRACT:
An internal-combustion engine having an electric starting motor, an ignition system, and an electric power source is provided with a control system allowing the engine to be stopped and restarted very easily. This system comprises a main ignition switch connected in series between the power source and the ignition system and closable to energize the ignition system from the power source. A manual start switch and an automatic start switch are connected in series between the main ignition switch and the electric starting motor and both are closable when the main ignition switch is closed to energize the starting motor from the power source. A speed-sensing circuit is connected to the engine and to the automatic start switch and is set up to open the automatic start switch and thereby deenergize the start motor when the engine is operating above a predetermined rate of approximately 500 rpm. A manual restart switch, which may be closed when the accelerator pedal and clutch pedal are both depressed, is connectable across the manual restart switch when the engine speed lies below a very low rate as detected by an oil-pressure switch. An interrupter switch is connected in series between the main ignition switch and the ignition system and is effective only when the vehicle is standing still. Thus the engine can be killed when the vehicle is standing still by means of the stop switch, but can be restarted simply by operation of the accelerator and clutch pedals.
