Abstract

An apparatus for treating the exhaust gas of internal combustion engine comprises an injector, a valve for shutting off the cooling water which flows into a cylinder head, an exhaust manifold increasing the fluidity of the exhaust gas, a close-coupled catalyst (CCC) increasing the activation of a catalyst with high loading operation in case of low temperate, an HC-absorber catalyst including an HC absorber and a TWC catalyst component for removing the HC component in the exhaust gas, and a electrically heated catalyst and a light off catalyst for removing the HC component at high temperate.
