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; electrical circuit means responsive to signals produced by associated engine exhaust gas analyzing means sensitive to selected constituents of such exhaust gas and also responsive to other selected indicia of vehicle and/or engine operating conditions, 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.
