APPARATUS, SYSTEM, AND METHOD FOR CONTROLLING PARTICULATE ACCUMULATION ON AN ENGINE FILTER DURING ENGINE IDLING

摘要

According to one representative embodiment, an apparatus (130) includes a regeneration event timing module (410) configured to determine a regeneration event timing strategy (415) for implementation during extended idling of an engine. The regeneration event timing strategy includes a first time period and a second time period. The apparatus includes an engine speed module (420) configured to operate the engine at a desired engine speed (423) during the second time period. The desired engine speed is greater than an idling engine speed associated with the first time period. An exhaust gas temperature module (430) of the apparatus is configured to determine a desired filter inlet exhaust gas temperature (440) for achieving noxidation regeneration of the filter. The apparatus also includes a thermal management module (275) configured to modulate at least one engine system component to achieve the desired filter inlet exhaust gas temperature during the second time period.
