  • at least one oil chamber forming an oil sump;

    at least one oil reservoir arranged separately from the oil chamber, the at least one oil reservoir at least partially arranged at the same geodetic height as the oil chamber;

    at least one fluid connection fluidically connecting the oil chamber to the oil reservoir;

    at least one electrically operable shut-off unit between the oil chamber and the oil reservoir, the at least one electrically operable shut-off unit blocking the at least one fluidic connection between the oil chamber and the oil reservoir in a blocking state and at least partially enabling fluidic connection between the oil chamber and the oil reservoir in a release state; and

    at least one electronic unit connected to the electrically operable shut-off unit regulating the blocking state and the release state based on a number of regeneration operations of the at least one soot particle filter and based on a degree of dilution of an oil present in the oil chamber.
