ENGINE PERFORMANCE MANAGEMENT DURING A DIESEL PARTICULATE FILTER REGENERATION EVENT

摘要

Embodiments of an apparatus, system, and method are disclosed for managing regeneration event characteristics. For example, in one embodiment, an apparatus (130) for controlling the temperature of the output exhaust of an internal combustion engine (110) for a regeneration event on a particulate matter filter (150) includes a regeneration module (260) that determines a desired particulate matter filter inlet exhaust gas temperature (425) for a regeneration event, a turbocharger thermal management module (405) that determines a variable geometry turbine (VGT) device position strategy, a fuel injection thermal management module (415) determines a fuel injection strategy, and an air intake thermal management module (420) that determines an intake throttle position strategy. The VGT device position strategy, post-injection fuel injection strategy, and 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.
