Abstract

A system, method and computer operable code is disclosed for reducing HC and liquid accumulation in an exhaust gas treatment system. A timer is used to monitor the amount of time the system spends in either absorption mode or desorption mode. If the exhaust gas temperature at the inlet of a oxidation catalyst device is below an absorption threshold, the timer is instructed to count up. If the exhaust gas temperature is above a desorption threshold, the timer is instructed to count down. At a predetermined timer threshold value, the engine is instructed to enter a thermal management mode operable to reduce accumulation of HC and liquid in the exhaust gas management system.
