ACTIVE REGENERATION DPF SYSTEM USING NON-WORKING LOAD AND METHOD OF THE SAME

摘要

PURPOSE: A vacuum compressor and a turbine generator structure are provided to rapidly increase the temperature of exhaust gas by applying non-work load to an engine and not the real work load of construction equipment. CONSTITUTION: A vacuum compressor and a turbine generator structure comprise an engine(110), DPF(diesel particle filter)(130), a diesel oxidation catalyst(DOC) unit(140), a fuel feeding unit(150), and a unit for forcibly generating loads. The DPF is placed in an exhaust line(120), in which exhaust gas from the engine is discharged outside. The diesel oxidation catalyst unit is placed in front of the DPF in the exhaust line. The fuel feeding unit injects the fuel, which exothermic-reacts with DOC(diesel oxidation catalysts to the diesel oxidation catalyst unit. The unit for forcibly generating the loads provides non-work loads to the engine. The unit for forcibly generating the loads comprises a main pump(160). The main pump discharges randomly generates working oil when the DPF is forcibly operated at the same time as that of the main pump generates the non-work loads.
