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 (NOx) and hydrocarbons. The main toxic components CO and NOx 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. An internal combustion engine has at least two combustion chambers having independent fuel preparation systems, which regulate the combustion process in terms of the proportions of the main toxic components in such a manner that quantitatively predetermined proportions of toxic substances in the exhaust gases are produced. After being mixed, the toxic components are detoxified practically completely with known catalytic systems. In an internal combustion engine operating on the self-ignition principle, if there is an insufficient amount of the main toxic component carbon monoxide for complete catalytic detoxification of the exhaust gas mixture, additional CO is supplied to the catalytic converter from a separate CO source.

A method for detoxifying exhaust gas components of a diesel engine, the engine having at least two combustion chambers with separate, regulatable fuel preparation systems and separate exhaust gas lines, exhaust gas sensors in the exhaust gas lines, a catalytic converter and a carbon monoxide source, said method comprising the steps of: sensing the exhaust gas components in the individual exhaust gas lines; regulating the air/fuel mixture supplied by each fuel preparation system to its respective combustion chamber so that a predetermined proportion is reached of the exhaust gas components of the exhaust gas lines; delivering the exhaust gas components from the exhaust gas lines to the catalytic converter; and supplying carbon monoxide to the catalytic converter as needed for detoxification of the exhaust gas components.
