Abstract
Systems, methods and apparatus are disclosed that include an exhaust system and an air source external to the exhaust system that is configured to force additional air into the exhaust stream downstream of the engine and aftertreatment system to help mix cool air with the exhaust. The amount and timing of the mixing of the forced air with the exhaust can be determined by an electronic controller so that mixing air is provided in response to one or more predetermined operating conditions and/or anticipated operating conditions.
