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.
