Abstract
A method of preventing damage to a Gasoline Particulate Filter (GPF) of a vehicle adapted to Cylinder De-activation (CDA) may include monitoring GPF pressure difference that measures a pressure difference of the GPF and determines an accumulation amount of soot in the GPF in accordance with the measured pressure difference of GPF; comparing pressure difference that compares the measured pressure difference of the GPF with a predetermined reproduction pressure difference; calculating GPF temperature that calculates a temperature in the GPF in accordance with each one of CDA modes, based on the accumulation amount of soot and an average oxygen concentration of an exhaust gas for the each one of the CDA modes; and setting CDA mode that determines a number of cylinders available for an CDA operation based on the calculated temperature and a predetermined temperature established for preventing the GPF from a damage.
