ABSTRACT:
An exhaust gas recirculation (EGR) control system for an internal combustion engine, in which an EGR control valve including a vacuum-operated actuator governs the flow of recirculated exhaust gas according to the admission of air into the engine. To accomplish the control with high precision, the control system includes a flow sensor which provides an electrical signal representing the volume flow rate of air in the induction passage and a control circuit for controlling the magnitude of vacuum for the EGR valve through the operation of an electromagnetic valve based on the signal from the flow sensor. Optionally the control system has another flow sensor which provides an electrical signal representing the volume flow rate of recirculated exhaust gas to the control circuit to accomplish a feedback control.
