  • Method for operating an active oil separator and device for separating oil
    Patent number: 11828211
    Abstract: A method for operating an active oil separator for separating oil from exhaust air of a crankcase of a motor vehicle with an internal combustion engine. An engine operating state of the internal combustion engine is detected. A first SET rotational speed of the oil separator is determined as a function of the detected engine operating state and a first characteristic map. A maximum SET rotational speed of the oil separator is determined as a function of the first SET rotational speed by the determination device. A preferred SET rotational speed is determined on the basis of the maximum SET rotational speed by a determination device. An electric motor is controlled to drive the oil separator at the preferred SET rotational speed by a control device. A device is also provided for separating oil from exhaust air of a crankcase of a motor vehicle with an internal combustion engine.
