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 |
20130072347 | DRIVETRAIN FOR A PARALLEL HYBRID VEHICLE - A drivetrain ( | 03-21-2013 |
20130247870 | ENGINE STARTING METHOD - A motor vehicle has an internal combustion engine and at least one electric motor as a drive motor arranged on a common shaft. The internal combustion engine and/or the electric motor can introduce torque into a transmission downstream in the drivetrain, and a separating clutch is provided between the internal combustion engine and the electric motor. The method increases torque of the electric machine, increasing the rotational speed of the electric machine and setting slip conditions at a clutch of the downstream transmission, engaging the separating clutch to a torque between the reserve torque of the electric motor and the maximum transmissible torque, reducing the transmissible torque of the separating clutch when the rotational speed of the internal combustion engine has reached the ignition rotational speed, ending the slip conditions of the at least one clutch of the downstream transmission, ending the increase of the torque of the electric motor. | 09-26-2013 |

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 |
20120148464 | EXHAUST-GAS AFTERTREATMENT SYSTEM WITH CATALYTICALLY ACTIVE WALL-FLOW FILTER WITH STORAGE FUNCTION UPSTREAM OF CATALYTIC CONVERTER WITH IDENTICAL STORAGE FUNCTION - The present invention relates to an exhaust-gas aftertreatment system which comprises a preferably catalytically active particle filter (wall-flow filter) which is followed in turn by a throughflow monolith (flow-through monolith) which is preferably provided with a catalytically active function. Both components have the same storage functions for gaseous substances present in the exhaust gas of internal combustion engines. The system is suitable in particular for the simultaneous removal of particles and pollutants from the exhaust gas of both predominantly lean-operated internal combustion engines and also of internal combustion engines operated predominantly with a stoichiometric air/fuel mixture. Likewise described is a process for the production and the use of such a system for exhaust-gas aftertreatment. | 06-14-2012 |

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 |
