  • Catalytic converter for a lean burn internal combustion engine
    Patent number: 6413483
    Abstract: A layered exhaust gas catalyst containing Pt in a first layer and Rb in a second layer is more selective for catalyzing the reaction between NOx and/or nitrate with hydrocarbons and/or CO than for catalyzing the reaction between hydrocarbons and/or CO with oxygen.
