Abstract
A system is provided for enhancing aftertreatment regeneration capability. The system includes an internal combustion engine producing an exhaust gas stream and an aftertreatment component that treats the exhaust gas stream, where the aftertreatment component includes a desired inlet exhaust gas temperature. The system includes an exhaust gas pressure device that modulates an exhaust pressure value, and a fuel injection system that provides a post-injection event. The system includes a controller that provides an exhaust pressure command and a fuel injection command in response to determining that a temperature of the exhaust gas stream is lower than the desired inlet exhaust gas temperature. The exhaust gas pressure device is responsive to the exhaust pressure command and the fuel injection system is responsive to the fuel injection command.
