ABSTRACT:
An electronic engine protector including an electronic pressure transducer that produces variable voltage output in proportion to the differential pressure of the engine crankcase and the atmosphere. Circuitry is provided for selectively adjusting the pressure trip point which represents the faulted mode wherein the engine's fuel solenoid is turned off. Further, circuitry provides for a selectively adjustable time delay to prevent engine shut down due to momentary engine overloads, atmospheric phenomena, or other such temporary conditions that generate a false shut down signal.
