Patent number: 11319888Abstract: A method for regulation of an internal combustion engine with an SCR catalytic converter in which the operating point of the engine is predefined by an engine control unit and the operating point of the catalytic converter is predefined by an SCR control unit. An overall system quality measure is calculated by an optimizer in accordance with fed back values of the engine control unit and fed back values of the SCR control unit, by changing the default values for the engine control unit and the SCR control unit, the optimizer minimizes the overall system quality measure for a prediction horizon regarding operating costs. On the basis of the minimized overall system quality measure the optimizer sets the default values for the engine control unit and the default values for the SCR control unit as decisive for setting the operating point of the engine and the catalytic converter.Type: GrantFiled: March 26, 2021Date of Patent: May 3, 2022Assignee: Rolls-Royce Solutions GmbHInventors: Knut Graichen, Daniel Bergmann, Roman Geiselhart, Jens Niemeyer, Jörg Remele, Karsten Harder, Tim Späder

Patent number: 11156183Abstract: A method for model-based open-loop and closed-loop control of an internal combustion engine, in which method injection system setpoint values for activating the injection system control elements are calculated dependent on a setpoint torque by a combustion model, and gas path setpoint values for activating the gas path control elements are calculated by a gas path model. The combustion model is adapted during ongoing operation of the internal combustion engine. A quality measure is calculated by an optimizer dependent on the injection system setpoint values and the gas path setpoint values, the quality measure is minimized by the optimizer by varying the injection system setpoint values and gas path setpoint values within a prediction horizon. The injection system setpoint values and gas path setpoint values are set by the optimizer, based on the minimized quality measure, as being definitive for setting of the operating point of the internal combustion engine.Type: GrantFiled: February 27, 2019Date of Patent: October 26, 2021Assignee: MTU FRIEDRICHSHAFEN GMBHInventors: Daniel Bergmann, Michael Buchholz, Knut Graichen, Jens Niemeyer

Publication number: 20210180535Abstract: A method for the model-based control and regulation of an internal combustion engine. The method includes calculating, as a function of a set torque, injection system set values for controlling the injection system actuators via a combustion model and calculating gas path set values for controlling the gas path actuators via a gas path model.
