Abstract: A method for determining cylinder-specific combustion features of an internal combustion engine, the cylinder-specific combustion features being ascertained from a variable which represents the crankshaft speed, especially being ascertained from a signal of a crankshaft sensor or camshaft sensor. The cylinder-specific combustion features include a combustion position of at least one cylinder and/or a torque of the crankshaft.

Abstract: The invention relates to a method and a device for controlling an internal combustion engine for which, in the light of performance characteristics, control parameters for at least one control element (100) are specified. A parameter is determined which characterizes the uneven running.

Abstract: A method for operating an internal combustion engine in which a first rotation parameter is measured at a first end of a shaft of the internal combustion engine, and individual-cylinder rotation parameters are determined using the first rotation parameter. The method is characterized in that a second rotation parameter is measured at a second end of the shaft, and the individual-cylinder rotation parameters are determined using the first rotation parameter and the second rotation parameter. A control unit that controls the method is also presented.

Abstract: A method for operating an internal combustion engine in which a combustion characteristic is ascertained. The combustion characteristic is ascertained in a cylinder-specific manner, and one or more application functions for the operation of the internal combustion engine is/are carried out as a function of the combustion characteristic.

Abstract: A method and a device for operating an internal combustion engine, in particular a motor vehicle having a plurality of cylinder banks are described, making it possible to eliminate fluctuations in a time trend in an output quantity of the internal combustion engine that may result due to differences in operation of different cylinder banks of the internal combustion engine. A characteristic value of the output quantity of the internal combustion engine is determined repeatedly over time. The thus formed time trend in the characteristic value for the output quantity of the internal combustion engine is filtered as a function of the operation of the cylinder banks.

Abstract: A method and a device for operating an internal combustion engine, particularly of a vehicle, having several cylinder banks are provided, which allow for a simplified control. For this purpose, a resulting requirement is formed by coordinating several output variable requirements of the internal combustion engine. The coordination of the requirements for several cylinder banks is performed jointly, and the resulting output variable requirement is then divided into several individual output variable requirements of each particular cylinder bank.

Abstract: An electric machine, preferably a rotary current generator (10) with a rectifier unit (26) on the rear end region of its bearing plate (12), is proposed in which the dissipation of its lost heat is to be improved. PLUS and MINUS heat sinks (27, 28) with the MINUS and PLUS diodes (31, 32) are screwed firmly in sandwichlike fashion, insulated from one another, to a circuit board (30) for the switching connections between diodes and winding terminals (17A) on the bearing plate (12). In particular to improve the cooling of the MINUS diodes (31), these diodes are in direct metal-to-metal contact by their bases (31a) with the bearing shield (12) there.
