  • Boost pressure control
    Patent number: 10968818
    Abstract: An internal combustion engine is provided having at least one turbocharger having a compressor and an exhaust gas turbine, at least two actuating members for controlling a boost pressure by the compressor, a measuring device for measuring at least one measurement signal, and a control device adapted to actuate the actuating members by varying a degree of opening of the actuating members. The control device of the internal combustion engine is configured to calculate a total degree of opening of the actuating members necessary to achieve a desired boost pressure provided by the compressor. This is in dependence on the at least one measurement signal. The control device is also configured to determine the total degree of opening split between each of the at least two actuating members, and to control each of the actuating members according to its individual degree of opening to reach the desired boost pressure.
