A system and method for desulfurizing an oxidation catalyst enhances fuel economy and reduces noxious exhaust gas emission as a consequence of increasing desulfurization period of the oxidation catalyst or shortening desulfurization time by reflecting desulfurization history consisting of natural desulfurization occurrence. The method may include detecting an inlet temperature of the oxidation catalyst, estimating natural desulfurization according to the inlet temperature of the oxidation catalyst, and resetting desulfurization time or desulfurization period by reflecting the estimated natural desulfurization. |
