Abstract
For cleaning of crankcase gas produced by an internal combustion engine, that is arranged for propelling a vehicle, use is made of a centrifugal separator having a centrifugal rotor that is mounted on the vehicle. The cleaning efficiency of the centrifugal separator is changed by changing the rotational speed of an electrical motor, that is connected to a source of current on the vehicle and arranged for driving said centrifugal rotor.
