| 20110203860 | METHOD FOR OPERATING A DRIVE SYSTEM FOR A MOTOR VEHICLE - A vehicle has an internal combustion engine, an electric drive device and a transmission with two component transmissions that can be selected simultaneously. Torque can be transmitted from the electric drive device and/or the internal combustion engine to at least one axle of the vehicle, and a torque can be transmitted from the axle to the electric drive device and/or the internal combustion engine. The internal combustion engine is adjusted from a deactivated state to an energized state. Torque is transmitted to the internal combustion engine by the axle and/or the electric drive device via one of two shifting elements to increase rotational speed of the internal combustion engine. The internal combustion engine is adjusted to a target rotational speed via one of the shifting elements. The connection between the internal combustion engine and the axle is produced via one of the shifting elements upon reaching the target rotational speed. | 08-25-2011 |

| 20100263357 | THREE WAY CATALYST - A double-layer three-way catalyst for purification of the exhaust gases from internal combustion engines which has excellent activity and thermal stability is described. The catalyst contains active aluminium oxide and a first cerium/zirconium mixed oxide which are both catalytically activated with palladium in the first layer applied to a catalyst support. In the second layer which is in direct contact with the exhaust gas, the catalyst likewise contains an active aluminium oxide and a second cerium/zirconium mixed oxide which are both catalytically activated with rhodium. The second cerium/zirconium mixed oxide has a higher zirconium oxide content than the first mixed oxide. | 10-21-2010 |

| 20100126154 | PALLADIUM-RHODIUM SINGLE-LAYER CATALYST - A one-layer three-way catalyst is described for the cleaning of the exhaust gases of internal combustion engines with outstanding activity and thermal stability. The catalyst comprises an active aluminum oxide, a first cerium/zirconium mixed oxide and a second cerium/zirconium mixed oxide. The first cerium/zirconium mixed oxide has a higher zirconium oxide content than the second mixed oxide. The first cerium/zirconium mixed oxide is catalytically activated with rhodium and the second cerium/zirconium mixed oxide with palladium. | 05-27-2010 |
| 20100135879 | TWO-LAYER-THREE-WAY CATALYST - A double-layer three-way catalyst is presented, which is formed from a catalytic coating applied directly to an inert honeycomb and a catalytically active coating thereon, and is suitable especially for cleaning of exhaust gases of motor vehicles with gasoline-operated internal combustion engines. The catalyst contains, in each layer, an active aluminum oxide and a cerium/zirconium mixed oxide, both of which are catalytically activated by palladium. The second layer on the gas side contains not only palladium but also rhodium, which is applied to the active aluminum oxide and the cerium/zirconium mixed oxide of the second layer in addition to the palladium. The cerium/zirconium mixed oxide of the second layer has a higher zirconium oxide content than the cerium/zirconium mixed oxide of the first layer. The catalyst is notable for exceptional activity coupled with outstanding aging stability. | 06-03-2010 |
