Solid state starting and operating system for a constant combustion engine

Claim 1

A starting and operating system for a constant combustion engine having a starter motor and a driver circuit for said starter motor, having means for discharging fuel into a combustion chamber of said engine and a driver circuit for said fuel discharge means, and having an ignition system for igniting fuel discharged into said combustion chamber and a driver circuit for said ignition system, said constant combustion engine starting and operating system comprising, in combination: an engine starting switch; means for indicating combustion in said combustion chamber; means for sensing whether the speed of said engine is above or below a first predetermined level; means for sensing whether the speed of said engine is above or below a second predetermined level; NOR gate logic circuit means for energizing said starter motor driver circuit, said fuel discharge means driver circuit, and said ignition system driver circuit when said starting switch is actuated and the speed of said engine is below said first predetermined level; NOR gate logic circuit means for de-energizing said starter motor driver circuit and said ignition system driver circuit when the speed of said engine exceeds said second predetermined level; NOR gate logic circuit means for de-energizing said starter motor driver circuit, said fuel discharge means driver circuit and said ignition system driver circuit if said combustion indicating means does not indicate combustion at the end of a predetermined time interval initiated by actuation of said starting switch; and NOR gate logic circuit means for de-energizing said fuel discharge means driver circuit if said combustion indicating means does not indicate combustion when the speed of said engine exceeds said second predetermined level.
