Abstract:
In an adjusting mechanism which is connected to first and second camshafts of a camshaft drive arrangement including a control device for adjusting the phase position of at least one of the camshafts relative to a crankshaft of an internal combustion engine, and having a drive device for driving the camshaft arrangement, a first partial mechanism for driving the first camshaft and a second partial mechanism for driving the second camshaft are provided so as to be driven in parallel by means of a common drive device for adjusting the angular position of the first and second camshafts relative to the crankshaft of the engine.
Abstract:
In a device for actuating at least one gas exchange valve of an internal combustion engine, comprising at least one pivoting armature, which is operatively connected to the gas exchange valve, and at least one first and at least one second electromagnetic units for actuating the pivoting armature, the pivoting armature is included in a first functional group with an armature housing and at least one of the two electromagnetic units is included in a second functional group and the functional groups are interconnected by connection means.
Abstract:
In an arrangement for providing electrical connections between an engine control unit and electric power consumers disposed on a cylinder head of an internal combustion engine, particularly an electromagnetic valve control arrangement, wherein the cylinder head comprises a first housing part and a second housing part consisting of a frame structure mounted onto the first housing part. The second housing part includes electrical components with receptacles which are connected outside the second housing part to the engine control unit and the power consumers have communication lines provided with plugs plugged into the receptacles within the second housing part for electrical connection to the engine control unit. A cylinderhead cover is mounted onto the frame structure.
Abstract:
