Abstract: An integrated intake manifold assembly including a first poppet valve assembly disposed at the air inlet to the manifold to regulate air flow into the manifold; a second poppet valve assembly disposed on the manifold to regulate exhaust gas flow into the air intake system; and a bi-directional camshaft with cams for operating simultaneously the manifold vacuum regulating (MVR) valve and the exhaust gas recirculation (EGR) valve. The valve bodies are integrally formed in the wall of the intake manifold. The camshaft is driven by a DC motor and gear train. The cams are arranged on the shaft to provide optimum synchronized opening and closing of the related valves. When used on a diesel engine, the manifold assembly may further include a swirl valve plate disposed between the manifold and the engine head and having a plurality of ganged swirl valves actuated by levers, connected to the camshaft internally of the manifold and swirl plate, for coordinated motion with the MVR and EGR valves. Preferably, the swirl valve plate is also ported as a distribution rail to receive exhaust gas from the single EGR valve and distribute it to the individual cylinders. The valve poppets of the MVR and EGR valves include forked yokes engaging the camshaft to minimize side loading of the valve stems by the cams.

Abstract: In a carburetor, a branch passage is connected to the fuel-air mixture passage for charging exhaust gases back into the fuel-air mixture. A control valve is positioned in the branch passage for regulating flow of the exhaust gases and a first spring biases the control valve into the closed position. A throttle valve in the fuel-air mixture passage is operatively coupled to the control valve by a linkage arrangement so that the two valves can be operated together. The linkage arrangement includes a second spring which permits movement of the throttle valve without corresponding movement of the control valve. Further, the linking arrangement provides a certain amount of play between the movement of the throttle valve and the control valve so that the operation of the control valve can be delayed relative to the opening movement of the throttle valve.
