Abstract: An exhaust runner includes an exhaust runner inlet, an exhaust nozzle outlet aperture, and an impingement insulator. The exhaust runner inlet is configured to receive a first flow of an exhaust gas from an internal combustion engine. The exhaust nozzle outlet aperture is defined by an intersection of a tip flow passage and an internal surface of the exhaust runner. The exhaust nozzle outlet aperture is configured to introduce a second flow of the exhaust gas into the first flow of the exhaust gas. An impingement zone is defined by a projection of the outlet aperture onto the internal surface of the runner in a direction of the second flow of the exhaust gas. The impingement insulator is collocated with the impingement zone.

Abstract: A modular exhaust manifold includes a plurality of exhaust manifold segments coupled together along a common axis. Exhaust manifold segments include a water jacket tube defining a liquid coolant passage around each of the plurality of exhaust manifold segments. The internal combustion engine also includes a coupling assembly for joining adjacent exhaust manifold segments. The coupling assembly includes a plurality of annular sealing devices configured to fit within a first set of grooves formed on an end portion of a first exhaust manifold segment. The coupling assembly also includes a spacing collar configured to attach to the end portion of the first exhaust manifold segment and couple with a fixed radial flange formed on an adjacent end portion of a second exhaust manifold segment to join the first exhaust manifold segment and the second exhaust manifold segment.

Abstract: An exhaust nozzle tip for an exhaust runner conveying a first flow of an exhaust gas includes an inlet, outlet, and nozzle passageway. The inlet receives a second flow of the exhaust gas from an internal combustion engine. The outlet introduces the second flow into the first flow in the exhaust runner. The nozzle passageway conveys the second flow from the inlet to the outlet and is defined by an upstream curved surface, and a downstream surface. The downstream surface includes a first downstream curve, a straight portion, and a second downstream curve. The first downstream curve transitions from perpendicular to the first flow to between 60 degrees and 15 degrees relative to the first flow. The straight portion extends from the first downstream curve. The second downstream curve transitions from the straight portion to a downstream portion of the exhaust runner.
