Abstract: A method for operating an internal combustion engine having an exhaust gas purification system. Intake air throttling is carried out in order to raise an exhaust gas temperature in a low-load mode and in a traction mode. The amount of intake air throttling is determined as function of an expected load demand so that, with an expected unchanged or decreasing load demand, an increased or maximum possible intake air throttling is set. With an expected rising load demand, however, no or reduced intake air throttling is set, and the expected load demand is estimated based on operating and ambient parameters of the internal combustion engine.

Abstract: An air supply mechanism for a vehicle seat has an air discharging opening which is provided in the upper region of the vehicle seat and via which the head, shoulder, and neck region of a seat occupant can be subjected to an airflow in order to reduce undesirable draft phenomena. The airflow can be regulated with a control device, by regulating a blower speed of a fan, and can be heated via a heating element. The heating element has three heating stages which can be selected by a manually setting a regulating device by the seat occupant in order to select a heating stage and/or by the control device in response to an external parameter value. It is possible for the control device to regulate the blower speed of the fan in response to a further external parameter value. This construction makes it possible for the sensation of heat experienced by the seat occupant to be taken into account in the elimination of a sensation of a draft.

Abstract: In an engine braking method for a supercharged internal combustion engine, wherein combustion air, which is under boost pressure and is supplied to the cylinders under the control of engine inlet and outlet valves, is compressed in the cylinders and is subsequently discharged into the exhaust tract, engine braking takes place in a two-stroke operating mode.

Abstract: The invention relates to a twin clutch transmission of high efficiency which is compact in every dimension. This twin clutch transmission can be used particularly in vehicles having a longitudinally installed engine. For this purpose, the transmission input shaft and the transmission output shaft are arranged coaxially with respect to one another, whereas the two countershafts are arranged parallel to one another. Furthermore, the shift sleeves are arranged in a special way, thus making seven forward gears and a plurality of reverse gears possible.

Abstract: A method for detecting surroundings by an automotive night vision system comprising several areas, including a detection area (3) in which surroundings related data is detected, an evaluation area within which the surroundings-related data detected by the night vision system is evaluated, and an area of representation in which information about the surroundings-related data detected therein is represented to the driver by an optical display unit. The area of representation is therefore restricted in the inventive method for detecting surroundings such that the area of representation comprises no more than the high beam area (2). The driver is shown only the surroundings related data which he/she would see anyway when actuating the conventional high beam due to the fact that the area of representation is restricted.
