INITIAL DPF REGENERATION METHOD

摘要

PURPOSE: An initial DPF(diesel particulate filter trap) regenerating method is provided to reduce error by correcting soot measurement by comparing the differential pressure after regeneration with an initial value. CONSTITUTION: An initial DPF(diesel particulate filter trap) regenerating method is as follows. Regeneration related variables are monitored and a DPF is re-generated(S20,S30). The differential pressure is compared after regeneration of the DPF (S40). The compared differential pressure is corrected according to accumulated soot mass(S60). The execution of the regeneration task is determined based on the corrected soot mass(S70). The regeneration is performed (S80).
