摘要： A method for adjusting a camshaft of an internal combustion engine during a stop phase and during a subsequent new startup phase of the internal combustion engine. Such methods are used, in particular, in so-called start-stop designs for combustion engines. The camshaft controls intake valves and/or exhaust valves of the internal combustion engine and is adjustable by a camshaft adjuster. By a desired startup position of the camshaft adjuster, control time points of the intake valves and/or the exhaust valves are defined in which mechanical work necessary for starting the internal combustion engine is reduced and/or pollutant emissions of the internal combustion engine are reduced. In the method according to the invention it is provided that the camshaft adjuster is set in a desired stop position during the stop phase. During a first section of the startup phase, the camshaft adjuster is set from the desired stop position into the desired startup position. During a second section of the startup phase, a setting of the camshaft adjuster is performed as a function of measured operating parameters of the internal combustion engine. Furthermore, the invention relates to an internal combustion engine with a camshaft that can be adjusted by a camshaft adjuster.

摘要： An electromotive camshaft adjuster for adjusting the angle of rotation of the camshaft (14) of an internal combustion engine relative to the crankshaft thereof is provided. The camshaft adjuster includes a triple-shaft gear mechanism, which has a driving wheel (2, 2a′) that is fixed to the crankshaft and is embodied as a sprocket or a synchronous belt wheel, an output part which is fixed to the camshaft, and an adjustment shaft (18, 18′) which is connected in a rotationally fixed manner to a rotor of an electric adjustment motor, having a stator that is fixed on the internal combustion engine. In order to keep the effort for producing the adjusting gears relatively low, the triple-shaft gear mechanism is preferably constructed as a swashplate or single eccentric internal gear drive (1, 25), the effort for production thereof being minimized by forming the same in a non-cutting manner, reducing the number of components, and inexpensively adjusting or compensating the backlash.

摘要： The invention relates to an electrically driven device (1) for the angular adjustment of a shaft relative to its drive (2), said device comprising an eccentric gearing that comprises at least one internally geared wheel and one spur gear that meshes with the internally geared wheel and can be driven by an electrically rotatable eccentric shaft. The considerable structural complexity and space requirement as also the noise level of prior art devices is reduced by the fact that the internally geared wheel is configured as a first and a second internally geared wheel (6, 9), and the spur gear is configured as a first and a second spur gear (16, 17) that have the same number of teeth and are rotatable in opposite directions, the internally geared wheels (6, 9) are connected to the drive (2) and the spur gears (16, 17) are connected to the camshaft and can be driven through a double eccentric shaft (20) comprising identical eccentrics (18, 19) arranged offset at 180° to each other.
