ABSTRACT:
A method of purifying exhaust gases of an internal combustion engine by a manifold reactor, wherein secondary air is dividedly supplied at first and second stages especially in a cold starting or accelerating condition of the engine, to burn combustible components in a stepwise manner while avoiding too much cooling of the exhaust gases before the recombustion of the combustible components takes place. This method is effected by a two-staged secondary air supply port structure operated by a control system which responds to operational conditions of the engine.
