    摘要： A multi-cylinder internal combustion engine is equipped with an EGR control system in which the amount of the exhaust gases recirculated back to the cylinders of the engine is controlled in accordance with the intake vacuum in an intake passageway. The engine is constructed and arranged to control the number of cylinders operated in accordance with engine operating conditions. The EGR control system is provided with a device which can maintain a suitable exhaust gas recirculation even when a certain number of cylinders are not operated.

    摘要： An EGR (Exhaust Gas Recirculation) control system comprises EGR control valve means including a first fluid chamber the vacuum in which increases and decreases in accordance with operating conditions of the engine whereby EGR control valve means control the recirculated amount of exhaust gases back to the engine and a second fluid chamber receiving therein a suction vacuum to thereby cause multiplication of the vacuum in the first chamber without altering the correspondency between the operating condition of the engine and the degree of opening of the EGR control valve means whereby the variable range of the vacuum in the first fluid chamber is optimally enlarged.An EGR control system further comprises relief valve means for reducing the EGR ratio below a predetermined constant level upon high speed low load operating condition of the engine and which includes a fluid chamber directly communicating with the first fluid chamber of the EGR control valve means whereby the relief valve means is operated by the vacuum substantially equal to the vacuum in the first fluid chamber of the EGR control valve means.

    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.

    摘要： Exhaust gas is recirculated to an intake manifold of an engine by a shut-off valve and a fluidic amplifier for modulation in accordance with different engine parameters. The shut-off valve is normally biased to a closed position and it is opened to permit recirculation in response to a signal received from a fluidic NOR gate which operates in accordance with position of a carburetor throttle, engine speed and engine temperature. The fluidic amplifier includes a power jet chamber receiving a supply of exhaust and a vent chamber in fluid communication with a venturi disposed in the exhaust manifold, a receiver chamber and a pair of control jets. One of the control jets may be in fluid communication with the intake manifold or with a carburetor venturi. The other control jet may be open to atmospheric pressure compensated for the effect of changes in air density or engine speed.

    摘要： A flow control valve for an exhaust gas purifying system which is divided into a first valve chamber into which the exhaust gases flow and a second valve chamber out of which the exhaust gases flow. A first valve means responsive to the exhaust gases controls the communication between the first and second valve chambers and a second valve means controls the operation of the first valve means in response to the negative pressure in an air intake system.
