For example, according to one embodiment, an apparatus for controlling the temperature of the output exhaust of an internal combustion engine for a regeneration event on a particulate matter filter includes a regeneration module, a turbocharger thermal management module, a fuel injection thermal management module, and an air intake thermal management module. The regeneration module determines a desired particulate matter filter inlet exhaust gas temperature for a regeneration event. The turbocharger thermal management module determines a variable geometry turbine (VGT) device position strategy. The fuel injection thermal management module determines a fuel injection strategy. The air intake thermal management module determines an intake throttle position strategy. The VGT device position strategy, the post-injection fuel injection strategy, and the intake throttle position strategy cooperatively achieve the desired particulate matter filter inlet exhaust gas temperature and maintain a fuel dilution level of the engine below a maximum fuel dilution level.
