  • Method and device for controlling a combustion system and for catalytic cleaning of exhaust gas, and combustion system
    Patent number: 6343468
    Abstract: A method and a device for controlling a combustion system, in particular an internal combustion engine, and for catalytic cleaning of exhaust gases, as well as a combustion system, catalytically remove a noxious substance from the exhaust gas with the aid of a fluid which is added in a metered manner to the noxious substance. A desired value for a mass flow of the noxious substance in the exhaust gas is prescribed in order to control the combustion system. In this way, the metered addition of the fluid in accordance with the mass flow of the noxious substance is substantially simplified.
