ABSTRACT:
Various embodiments of an apparatus, system, and method are disclosed for managing regeneration event characteristics. For example, according to one embodiment, an apparatus for controlling the temperature of the outlet exhaust of an internal combustion engine for a regeneration event on a particulate matter filter includes a regeneration module and a fuel injection strategy module. The regeneration module is configured to determine a desired engine outlet exhaust gas temperature for a regeneration event. The fuel injection strategy module is configured to determine a regeneration fuel injection strategy for achieving the desired engine outlet exhaust gas temperature. The regeneration fuel injection strategy includes a main fuel injection, a first heat post-injection, and a second heat post-injection. In certain implementations, the fuel injection strategy also includes at least one or two non-heat post-injections for achieving a desired particulate filter inlet exhaust gas temperature.
