ABSTRACT:
A method and an apparatus for reducing harmful emissions in the exhaust gases of an internal combustion engine which may be a Diesel engine or an Otto engine operated by a lean fuel air mixture. The exhaust gases are subjected to a catalytic treatment for oxidizing carbon monoxide and hydrocarbons, and the exhaust gases are throttled to increase their temperature under operative conditions of heat deficiency such as at cold start. The exhaust gases are subjected to an additional catalytic treatment for reducing nitrogen oxides in a deoxidation means. The throttling of the exhaust gases is controlled such that the temperature of the exhaust gases will be within a predetermined temperature range at which said deoxidation means is operative.
