摘要： An engine exhaust gas recirculation system has an E.G.R. passage extending from an exhaust system of the engine to an intake system thereof downstream of an engine throttle valve. First and second E.G.R. control valves are provided at first and second points in the E.G.R. passage to control the exhaust gas-flow cross-sectional area of the E.G.R. passage at the first and second points, respectively. The first E.G.R. control valve is operatively connected to the throttle valve and disposed downstream of the second E.G.R. control valve. The intake air pressure upstream of the throttle valve is compared with the exhaust gas pressure between the first and second E.G.R. control valves to control the second E.G.R. control valve such that the exhaust gas pressure in the E.G.R. passage between the first and second E.G.R. control valves is made substantially equal to the air pressure in the engine intake system between the throttle valve and a venturi of a carburetor.
