摘要： An exemplary embodiment of the present disclosure relates to a system for active regeneration of a DPF of a diesel engine, and more particularly, to a system and a method for active regeneration of a DPF including an electro-hydraulic pump, in which a non-work load is arbitrarily provided to the diesel engine to quickly perform active regeneration of the DPF even in a state in which substantial work of the construction machine having an electro-hydraulic pump is stopped, and to this end, provides a system and a method for active regeneration of a DPF of a construction machine in that, when performing the active regeneration of the DPF, a center bypass cut valve is driven to convert a hydraulic system of the construction machine to an open state, a predetermined flow rate of working fluid is discharged from the electro-hydraulic pump using an adjustor such as an electromagnetic proportional control valve (EPPR), and the working fluid is collected in to a tank through an opened center bypass line, thus allowing the working fluid to flow without driving a working machine to produce a so-called non-work load, and the engine is overheated by the load, and the temperature of the exhaust gas is raised to a predetermined temperature so as to satisfy a temperature condition required for the active regeneration of the DPF.
