Abstract: An exhaust manifold apparatus for routing an exhaust gas produced by an internal combustion engine is described. The manifold includes a manifold log with a log wall that defines a log bore. The log bore is in fluid communication with an upstream opening of the manifold log and a downstream opening of the manifold log. An inlet runner includes a runner wall that defines a runner bore in fluid communication with the log bore. The inlet runner is engaged to the manifold log at a stress point, which also includes at least one stiffening rib disposed on an interior surface of the log wall and/or the inlet runner wall.

Abstract: Exhaust manifold assemblies for use in routing exhaust gas from engines are disclosed. An example assembly includes a first manifold section. The first manifold section includes a first body portion defining a first fluid passage. A first annular flange is disposed about a periphery of an end of the first body portion. The first annular flange has a first sealing face and an annular shoulder extending axially outward therefrom. A second manifold section includes a second body portion defining a second fluid passage. A second annular flange is disposed about a periphery of an end of the second body portion. The second annular flange has a second sealing face and a second annular shoulder extending axially outward therefrom. A bellows extends between and fluidly couples the first and second annular flanges and fluidly couples the first and second fluid passages.

Abstract: An engine assembly and methods of supporting components of an engine assembly. An internal combustion engine includes an intake port. A charge air cooler is coupled to the intake port. A turbocharger including a charge air output port is fluidly coupled to the charge air cooler. A charge air tube is coupled to the charge air output port of the turbocharger. The charge air tube fluidly couples the turbocharger to the charge air cooler for transfer of compressed charge air from the turbocharger to the intake port of the internal combustion engine. A charge air tube support assembly is coupled to the charge air tube. The charge air tube support assembly is configured to allow axial displacement of the charge air tube along an axis of the charge air tube extending from the output port of the turbocharger to the charge air cooler in response to thermal expansion of the charge air tube. The charge air tube support assembly comprises a wear sleeve and a clamp.

Abstract: An intake manifold is provided that controls swirl on entry to a combustion chamber. Each intake manifold includes a fin or rib portion positioned to reduce or eliminate swirl induced by the configuration of the intake manifold, particularly when used in a large engine having a left bank and a right bank of combustion chambers. By controlling swirl induced by the intake manifold, swirl consistency is improved between engine cylinders and between the left bank and the right bank, improving the consistency of power output and reducing emissions, particularly particulate emissions, also called smoke.
