A governor system for an engine motive fluid induction system is shown as having a solenoid operated valve assembly communicating with a source of vacuum and with a vacuum motor assembly operatively connected to a variably positionable throttle valve of the induction system; an electronic control sensitive to the speed of a monitored parameter is effective to controllably energize the solenoid valve assembly to in turn regulate the magnitude of vacuum directed thereby to the vacuum motor assembly and consequently govern the then permissible amount of opening of the throttle valve.

Governor apparatus and system

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.
