Abstract
A carbureting type fuel metering apparatus has an induction passage into which fuel is fed by several fuel metering systems among which are a main fuel metering system 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 feedback signal means which through associated solenoid transducer means become effective for controllably modulating the metering characteristics of the main fuel metering system, and, if desired, the idle fuel metering system as to thereby achieve the then desired optimum metering functions.
