  • Patent number: 4134368
    Abstract: A plurality of sensors generate signals representing engine parameters indicative of the engine fuel requirement. These signals are all applied to a single function generator to form a composite signal that is a nonlinear function of the engine fuel requirement. One of the sensors responds to absolute intake manifold pressure; responsive to this sensor, operation is inhibited, while the absolute intake manifold pressure is below a predetermined value representative of engine deceleration. An engine starter switch generates a trigger pulse to actuate an overriding multivibrator that overrides normal operation as the engine is started. One of the sensors also responds to engine coolant temperature; responsive to this sensor, the actuation duration of the overriding multivibrator is controlled in reverse relation to the coolant temperature.
