Abstract
A system includes an internal combustion engine, an EGR flow path having an EGR cooler path and an EGR cooler bypass path, a turbocharger, a compressed intake flow path, an EGR bypass valve that selectively divides the EGR flow between the EGR cooler path and the EGR cooler bypass path, a charge air cooler bypass valve that reduces an amount of cooling of compressed intake air out of the compression side of the turbocharger, and an aftertreatment component that receives the exhaust stream from the turbine side of the turbocharger. The aftertreatment component requires at least intermittent exhaust stream temperature elevation. The system includes a controller that determines that an exhaust stream temperature elevation request is present, and provides a charge air cooler bypass valve command and an EGR bypass valve command in response to the exhaust stream temperature elevation request.
