The present invention relates to a method for determining a DOC regeneration cycle, capable of improving purification performances by determining a cycle to repeatedly approve rich mixed air during operation of a diesel engine and activating DOC generation. The temperature of a DOC end is maintained at a range between 250-750°C in a condition approving step (S130). [Reference numerals] (AA) Start; (S130) Density condition?; (S150) Measure a DOC end temperature in a sparse condition; (S170) Accumulated heat load value > Threshold? |
