摘要： There is disclosed an exhaust manifold comprising a plurality of exhaust intake conduits and an exhaust intake manifold. Each of the plurality of exhaust intake conduits is structured to be fluidly coupled to an engine and structured to receive exhaust gas from a corresponding cylinder of the engine. The exhaust intake manifold is fluidly coupled to an exhaust intake conduit outlet of at least one of the plurality of exhaust intake conduits. Each of the plurality of exhaust intake conduits and the exhaust intake manifold define an exhaust intake manifold core volume. Each of the plurality of exhaust intake conduits and the exhaust intake manifold are shaped so as to define the exhaust intake manifold core volume based on at least one of the displacement of the engine, the intended operating power of the engine, and the intended flow rate of the exhaust gas through the exhaust manifold.

摘要： An exhaust manifold comprises a plurality of exhaust intake conduits structured to be fluidly coupled to an engine and receive exhaust gas from a corresponding cylinder of the engine. At least one exhaust intake conduit provides a reduction in an exhaust intake conduit cross-sectional area from an inlet to an outlet. A plurality of bends are each defined by a respective one of the exhaust intake conduit outlets. An exhaust intake manifold is fluidly coupled to the exhaust intake manifold and defines an exhaust intake manifold flow axis. Each of the plurality of bends is shaped so as to define an angle of approach of exhaust gas flowing therethrough. A first angle of approach of the first bend relative to the exhaust intake manifold flow axis is smaller than a second angle of approach of an inner second bend.
