CONSTITUTION: In a control drive of a valve train having a variable adjusting stroke in a valve of an internal combustion engine, a camshaft(1) is rotatably installed to a cinder head(ZK) and the camshaft has a fixed position fixed with respect to valves(2) and stroke transmission arrangements(3). The stroke transmission arrangements are arranged to the valves arranged to the cylinder head and closed by spring action. An in-situ variable element(4) for valve stroke control is fixed and guided to the cylinder head and is rotatably arranged around a rotating shaft(A4) fixed to the cylinder head. A link(5) engaging with cams by spring action is supported and guided to the in-situ variable element. The link continuously engages with the valves of the camshaft fixed to the cylinder head and the stroke transmission arrangements arranged to the valves. A control lever to cope with torsion is provided to the in-situ variable element. The control lever is engaged with a control slide movably guided to the cylinder head. The control slide operated by a servomotor has a control bar. The control levers are situated at one or both sides of the control bar.

Abstract: A method according to the invention for controlling an internal combustion engine having a camshaft whose phase with respect to a crankshaft can be adjusted by means of an electric adjustment device, and a control device comprises the steps S1 to S3, wherein in step S1 a stop request is output from the control device to the electric adjustment device. Subsequently, in step S2 a manipulated variable in the form of a pulse duty factor is output from the electric adjustment device, wherein the pulse duty factor counteracts a camshaft torque. In step S3, the direction of rotation of the camshaft is monitored, wherein in step S4, when a reversal of the direction of rotation of the camshaft is detected, an intensity level of this reversal of the direction of rotation is calculated by determining a rotational speed gradient. Furthermore, in a step S5 the pulse duty factor is corrected as a function of the rotational speed gradient in such a way that the influence of the reversal of the direction of rotation on the position of the camshaft is compensated.

Abstract: An engine assembly includes a control module configured to receive a torque request and an engine configured to produce an output torque in response to the torque request. The control module includes a processor and tangible, non-transitory memory on which is recorded instructions for executing a method for supervisory model predictive control. The control module includes a multi-layered structure with an upper-level (“UL”) optimizer module configured to optimize at least one system-level objective and a lower-level (“LL”) tracking control module configured to maintain at least one tracking parameter. The multi-layered structure is characterized by a decoupled cost function such that the UL optimizer module minimizes an upper-level cost function (CFUL) and the LL tracking control module minimizes a lower-level cost function (CFLL). The system-level objective may include minimizing fuel consumption of the engine and the tracking parameter may include delivering the torque requested to engine.
