ABSTRACT:
A restrictor in an exhaust gas feed conduit to the intake manifold has therein an opening operable to allow the exhaust gases passing through the opening to have a sonic velocity. A valve operates in response to the flow rate of the intake air passing through the carburetor for proportionally controlling the flow rate of the feeding exhaust gases with that of the intake air. The flow rate communicated to the valve has an atmospheric bleed controlled by a solenoid valve energized by a transmission switch.
