  • Method and device for removing oxidic noxious substances in an oxygen-containing exhaust gas and engine which is operated therewith
    Patent number: 6247303
    Abstract: To clean the exhaust gas of internal-combustion engines or other machines which are operated with fossil fuel, it is proposed to firstly pretreat the exhaust gas in a non-thermal normal-pressure gas discharge and subsequently allow a selective catalytic reduction of oxidic noxious substances to take place with the addition of a suitable reduction substance, or to allow a selective catalytic decomposition to take place. The device for removing the oxidic noxious substances is characterized by a series circuit of at least one module with a gas discharge section and at least one module with a catalytic-converter section, and is suitable in particular for use in a diesel engine.
