ABSTRACT:
An exhaust gas recirculation control system employs a flow rate valve in the recirculation line. The valve is operated by suction pressure obtained from two suction ports in the engine intake passage. Suction lines from those ports contain air inlet valves which dilute the suction pressure with atmospheric air, depending upon engine operating conditions. A fuel supply increasing valve is connected to a venturi in the engine intake passage and suction operated control means control operation of that valve. The result is an improved acceleration characteristic for the engine under load without substantial increase in discharge of pollutants into the atmosphere.
