<p>The present invention relates to an active DPF regeneration system of an engine of a construction machine, and more particularly, to an active DPF regeneration system and method, in which a non-work load is arbitrarily provided to the engine to quickly perform an active DPF regeneration, and, for example, provides an active DPF regeneration system and method, in which an engine is driven by arbitrarily receiving a non-work load by controlling a main pump to discharge a maximum flow of working fluid without performing substantial work, and thus a high temperature exhaust gas is discharged to facilitate an exothermic reaction between a DOC and a fuel, and thus the active DPF regeneration is more quickly performed compared to a case where the engine is driven in the idle state having no substantial load, and thus regeneration efficiency may be improved in terms of a time and cost by completing the active DFP regeneration within a decreased time compared to the related art.</p> |
