Abstract
A carbureting type fuel metering apparatus has a primary and secondary induction passage into which fuel is fed by several fuel metering systems among which are primary and secondary main fuel metering systems and an idle fuel metering system, as generally known in the art; engine exhaust gas analyzing means sensitive to selected constituents of such exhaust gas creates a feedback signal which through an associated solenoid transducer becomes effective for controllably modulating the metering characteristics of the main fuel metering system systems, and, if desired, the idle fuel metering system as to thereby achieve the then desired optimum metering function; the solenoid transducer is shown as simultaneously controlling two valving members and is effective upon experiencing a failure to assume a position providing for a rich fuel mode of engine operation.
