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.
