Fuel injection fuel control system

A fuel control system for a fuel injected engine includes two vacuum control circuits, essentially identical in valve structure. One circuit controls the recirculation of exhaust gases into the engine intake manifold (14) and a change in engine ignition timing in response to engine throttle valve (3...

Beschreibung
Zusammenfassung:	A fuel control system for a fuel injected engine includes two vacuum control circuits, essentially identical in valve structure. One circuit controls the recirculation of exhaust gases into the engine intake manifold (14) and a change in engine ignition timing in response to engine throttle valve (34) angle by a regulator (310), in response to changes in engine temperature by a signal reducer (312), and in response to engine load by a manifold vacuum sensitive valve (314). A second circuit controls the engine fuel injection pump fuel flow rate as a function of changes in throttle valve angle by a valve (420), engine temperature levels by a valve (422), and load levels by a valve (424) to adjust an engine air/fuel ratio controller (52) to maintain either a base air/fuel ratio or air/fuel ratios as called for by the particular engine operating conditions.
