摘要： For an internal combustion engine with a common rail system including individual accumulators, a process for open- and closed-loop control is proposed, in which the individual accumulator pressure (pE) is detected within a measuring interval and stored, an absolute minimum value of the stored individual accumulator pressure (pE) is interpreted as the end of the main injection, and on the basis of the end of the main injection, a mathematical function is used to calculate a virtual starting time for the main injection. In the measuring interval after the end of the main injection, the individual accumulator pressure (pE) is filtered within a time window, a local minimum value of the filtered individual accumulator pressure is interpreted as the end of a post-injection, and a mathematical function is used to calculate a virtual start of the post-injection.

摘要： A method for controlling an internal combustion engine having a common rail system together with individual accumulators. A rotational speed-control deviation (dn) is determined from a target rotational speed (nSL) that represents the set point for an outer control loop to control the rotational speed, as well as from an actual rotational speed (nIST). A target torque (MSL) is determined from the rotational speed-control deviation (dn) via a rotational speed controller as a master controller. A target injection duration (SD(SOLL)) is determined from the target torque (MSL). The target duration injection (SD(SOLL)) represents the set point for an inner control loop for controlling cylinder-specific injection duration. An injection duration deviation is determined from the target injection duration (SD(SOLL)) and from an actual injection duration. A correcting variable is determined from the injection duration deviation via an injection duration controller as a follow-up controller, and an injection duration is determined from the correcting variable and the target injection duration for activating the injectors.

摘要： In a method for a model-based determination of a temperature distribution of an exhaust gas post-treatment unit, a differentiation is made between steady operating states and non-steady operating states by taking into account the axial and the radial temperature distribution, and, on the basis of virtual segmentation of the post-treatment unit, in particular the radial heat transfer to the surroundings is taken into account in the model-based determination for steady operating states, and for non-steady operating states the heat transfer from the exhaust gas which flows axially through the post-treatment unit to the segments is taken into account by a heat transfer coefficient k.

摘要： A method for automatically controlling an internal combustion engine, in which an axial displacement (s(t)) and an angle of rotation (w(t)) of a gas-exchange valve are measured during a valve stroke. A displacement deviation is computed from the displacement (s(t)) relative to a reference valve, and an angle of rotation deviation is computed from an initial value and an end value of the angle or rotation. The further operation of the internal combustion engine is set on the basis of the displacement deviation and the angle of rotation deviation.

摘要： A method for automatically controlling the speed of a ship, in which the engine speed (nMOT) is automatically controlled by a closed-loop engine speed control system as an inner closed-loop control system, the ship's speed (vS) is automatically controlled by a closed-loop ship's speed control system as an outer closed-loop control system, and the ship's set speed (vSL) is influenced as a reference input of the closed-loop ship's speed control system as a function of an external signal source. The ship's set speed (vSL) is corrected as a function of the underwater topography (TOPO).
