Abstract: An internally ventilated brake disc includes at least two friction rings, which are held apart from each other by ribs, and air blades, which are fastened to the brake disc and which extend essentially from the inner circumference of a friction ring in the radial direction by a defined amount in the direction of the axis of rotation of the brake disc. The air blades function to deliver a cooling air flow through the space between the friction rings when the brake disc is rotating. The air blades are formed by one or more sheet metal part(s) that is or are connected to at least some of the ribs. This connection can be by material bonding or can be shape locking or force locking. The air blades are machined out of a sheet metal ring and, thus, form an integral sheet metal part, wherein the sheet metal ring is provided with a plurality of clamps or clips for a shape-locking connection to the ribs and is not formed so as to be closed.

Abstract: A cutting tool, particularly for steel sheet billets, having a cutting blade fastened to a blade holder and a pressure cushion which is arranged on sides of the blade holder and, when the cutting blade penetrates into the material to be punched, is pressed onto the latter in the area of the useful punched part. During the passage of the cutting blade, a high-quality edge of the useful punched part is largely kept free of an interfering burr and elevation formation by the pressure cushion material being displaced radially outward during the punching stroke, such that the cutting blade is acted upon by pressure in the lateral direction under an increasing elastic deflection of the cutting blade edge.

Abstract: A process and system are provided for determining fuel consumption of a motor vehicle. A first mean fuel consumption, which cannot be reset under a user's influence, is determined. A second mean fuel consumption, which can be reset under a user's influence, is determined as a function of several measured values. A third mean fuel consumption is determined as follows: (a) at the beginning of a predefined time period, which starts with a resetting of the second mean fuel consumption, the third mean fuel consumption is set to be equal to the first mean fuel consumption; (b) between the beginning and the end of the predefined time period, the third mean fuel consumption is set to be a weighted mean of the first mean fuel consumption and the second mean fuel consumption; and, (c) starting at an end of the predefined time period, the third mean fuel consumption is set to be equal to the second mean fuel consumption. A signal indicative of the third mean fuel consumption is provided.

Abstract: A backrest for a vehicle seat includes a backrest frame, which is surrounded by a cover and has an upper backrest with an adjustable inclination. An additional frame is hinged so as to be pivotable about a pivot axis to a side plate, the cover, or the backrest frame. The pivot axis is arranged in an upper region of the backrest, and the additional frame extends upwards from the pivot axis in the installed position of the backrest. The additional frame can be secured in different angular positions in relation to the backrest frame, and, thus, a variable gap forms between the additional cover of the additional frame and the cover of the backrest frame.

Abstract: An internal-combustion engine can be operated in a homogeneous charge compression ignition mode at least under certain operating conditions. The combustion mixture present in the combustion chamber reaches auto-ignition conditions and ignites itself. The internal-combustion engine includes a triggering unit for triggering the auto-ignition during the homogeneous charge compression ignition mode before the auto-ignition conditions have been reached. The triggering unit is constructed as a corona ignition system and can be operated for triggering the auto-ignition during the homogeneous charge compression ignition mode, particularly by generating a non-thermal plasma.

If the internal-combustion engine is automatically turned off, an automatic starting of the internal-combustion engine by releasing the brake is prevented if the brake pedal was increasingly depressed beforehand while the internal-combustion engine was turned-off.

Abstract: A twin scroll exhaust gas turbocharger for an internal-combustion engine, includes a turbine housing and a first and a second gas inlet port separated from one another by the turbine housing. The inlet ports lead into a first and a second spiral duct, respectively, which extend radially on the outside around an exhaust gas turbine rotatable about an axis. The gas inlet ports are arranged at least in sections parallel to one another in the turbine housing and radially with respect to the axis of rotation in a mutually spaced manner. The first spiral duct, which connects to the first gas inlet port arranged closer to the axis of rotation, extends up to 180° around the exhaust gas turbine. The second spiral duct, which connects to the second gas inlet port farther away from the axis of rotation, extends up to 180° around the remaining circumference of the exhaust gas turbine. As a result, thermal stress to the turbine housing is significantly reduced.
