摘要： An integrated intake manifold assembly (10) including a poppet valve (16) disposed at the air inlet (96) to the manifold (12) to regulate air flow into the manifold; a poppet valve (20) disposed on the manifold to regulate exhaust gas flow into the air intake system; and a bi-directional camshaft (82) with cams (86,88) for operating simultaneously the manifold vacuum regulating (MVR) valve (16) and the exhaust gas recirculation (EGR) valve (20). The valve bodies (14,18) are integrally formed in the wall of the intake manifold. The camshaft is driven by a DC motor (70) and gear train (72,74,76,78,80) . The cams are arranged on the shaft to provide optimum synchronized opening and closing of the related valves. When used on a diesel engine (32), the assembly may further include a swirl valve plate (44) disposed between the manifold and the engine head and having a plurality of ganged swirl valves (50) actuated by levers (28,56,58) connected to the camshaft for coordinated motion with the MVR and EGR valves. Preferably, the swirl valve plate is also ported as a distribution rail (64) 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 (130) engaging the camshaft to minimize side loading of the valve stems by the cams. Prefreably, the cam operating the MVR valve includes a hook to positively bias the valve closed against the valve seat.

摘要： An integrated intake manifold assembly (10) including a poppet valve (92) disposed at the air inlet to the manifold to regulate air flow into the manifold; a poppet valve (108) disposed on the manifold to regulate exhaust gas flow into the air intake system; and a bi-directional camshaft (82) with cams (86, 88) 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 (70) and gear train (72, 74, 80). 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 assembly may further include a swirl valve plate (44) disposed between the manifold and the engine head and having a plurality of ganged swirl valves (50) actuated by levers (138) connected to the camshaft for coordinated motion with the MVR and EGR valves. Preferably, the swirl valve plate is also ported (66) as a distribution rail to receive exhaust gas from the single EGR valve and distribute it to the individual cylinders. The valve stems of the MVR and EGR valves are modified as forked yokes (130) engaging the camshaft to minimize side loading of the valve stems by the cams.

摘要： Vorrichtung zur Strömungsbeeinflussung der Ansaugluft in einem Saugkanal einer ventilgesteuerten Brennkraftmaschine mit einem, in Strömungsrichtung vor einem Ventilsitz angeordneten, den Saugkanalquerschnitt mit einer Wirkfläche beeinflussenden Steuerelement, wobei das Steuerelement weitestgehend ringförmig ausgebildet und um die Saugkanallängsachse exzentrisch drehbeweglich angeordnet ist. Diese Lösung zeichnet sich vor allem dadurch aus, dass das Steuerelement in den Saugkanal oder den Zylinderkopf vollständig integriert werden kann, ohne die für die Ansaugluft strömungsoptimierte Geometrie zu verändern. Je nach Lage der Wirkfläche des Steuerelementes, kann die Drallbeeinflussung entweder ganz ausgeschaltet sein oder kontinuierlich zur Verstärkung des Dralls im Brennraum zugeschaltet werden.
