A METHOD AND A DEVICE FOR CLEANING OF CRANKCASE GAS |
摘要 |
Upon cleaning of crankcase gas generated during operation of an internal combustion engine (31; 41) in its crankcase, a centrifugal separator (34; 50) is used, which includes a rotor arranged for rotation by means of a driving motor (9; 49) and arranged by its rotation to suck crankcase gas from the crankcase through a conduit (51) to the centrifugal separator. During operation of the combustion engine (31; 41) a parameter, e.g. a measurement of the load on the combustion engine (31; 41), is sensed, the magnitude of said parameter being related to the amount of crankcase gas generated per unit of time in the crankcase. Depending upon a sensed change of the sensed parameter the rotational speed of the rotor of the centrifugal separator (34; 50) is changed in a way such that the gas pressure in the crankcase is maintained at a predetermined value, or within a predetermined pressure interval, during the operation of the combustion engine (31; 41).
