GPF Method for Prediction of Soot Burning During GPF Regeneration

摘要

The present invention relates to a method for accurately predicting soot combustion during GPF regeneration. The method for predicting soot combustion during GPF regeneration according to the present invention predicts soot combustion by a soot combustion rate calculated by dividing a regeneration process into an initial combustion period in which combustion suddenly occurs and a later combustion period thereafter. In addition, the method for predicting soot combustion during GPF regeneration according to the present invention calculates a soot combustion rate by applying an outside temperature factor.
