  • Patent number: 4793135
    Abstract: The invention relates to a method for detoxification of the exhaust gas from an internal combustion engine 1 using a catalytic system. The main toxic components in the exhaust gas mixture are carbon monoxide (CO), nitrogen oxides (NO.sub.x) and hydrocarbons. The main toxic components CO and NO.sub.x are liberated from their interdependent relationship. The production of the main toxic components is quantitatively varied individually by regulation of separate combustion chambers. The toxic components from exhaust gas pipes of the respective combustion chambers are combined, in such a manner that in accordance with the proportions of the main toxic components, the composition of the exhaust gas mixture enables complete catalytic after-combustion conversion thereof in a known manner.
