  • Intake manifold with improved exhaust gas recirculation
    Patent number: 6691686
    Abstract: Intake manifolds for an internal combustion engine and methods of using the same are disclosed. The intake manifolds accommodate the introduction of exhaust gas that has been recirculated from the main exhaust gas stream. The exhaust gas can be introduced into the intake manifold through aerodynamically shaped members that are located inside the manifold. Alternatively, the exhaust gas can be introduced into the manifold at or near the intersection of the primary runners and the plena, or the exhaust gas can be introduced into a mixing chamber located between the primary runners and the plena.
