Zusammenfassung: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 transducer means become effective for controllably modulating the metering characteristics of the main fuel metering system and the idle fuel metering system; reciprocating type solenoid control valve means is employed for modulating actuating pressure applied to the structure of the main fuel metering system and idle fuel metering system in order to achieve the desired metering functions.
