ABSTRACT:
A fuel control system comprises a probe in contact with the exhaust gases, a circuit for supplying fuel and air to the engine, having a solenoid valve for metering at least the fuel flow, a closed-loop electronic control circuit connected to the probe and energizing the solenoid valve in dependence on the signal from the probe. The loop is opened responsive to predetermined operating conditions of the engine. Further means control the solenoid valve in dependence on another engine operating parameter during open-loop operation. A memory is provided for storing a value representative of the control of the solenoid valve means during closed-loop operation.
