Abstract: A circuit for recognizing and providing full-load enrichment fuel compensation for an electronic fuel control system is described herein. The circuit is adapted to recognize a signal which may be an engine operating parameter indicative of engine operation under full load and to thereafter incrementally increase the duration of the fuel injection command pulse generated by the main electronic fuel control system. In those electronic fuel control systems which provide a fuel injection command pulse whenever a generated voltage waveshape is below a threshold value, the present invention contemplates altering the shape of the generated waveshape to delay its excursion through the threshold value.

Abstract: A tip-in fuel enrichment circuit is disclosed for the fuel delivery system of an internal combustion engine which senses a closed throttle position signal generated by a switch associated with the engine''s throttle in its closed position and generates a fuel enrichment signal providing a predetermined increase in the fuel delivery to the engine each time the closed throttle position signal is terminated.

Abstract: By deriving a substantially linear voltage signal from a pressure transducer and using that signal to control a plurality of current sources and current sinks, the controlled current may be passed through a resistance of known value to produce a usable output signal having a nonlinear relationship with respect to the pressure sensed by the transducer. If current sources to be controlled are designated by N, the resultant curve can have N-1 break points where the slope of the curve of output voltage with respect to sensed pressure changes.
