Abstract
The invention relates to a method for de-oiling crankcase ventilation gases of an internal combustion engine wherein an oil separating element, like a cyclone has crankcase ventilation gases flowing therethrough, and the oil droplets contained therein are separated. The method provides that the volume stream of the crankcase ventilation gases is divided in at least two partial volume streams, and at least one partial volume stream is guided through at least one oil separating element, wherein the magnitude of the at least two partial volume streams is controlled depending on the magnitude of the volume stream. Furthermore the invention relates to apparatus for accomplishing the method.
Claims34
A method for de-oiling crankcase ventilation gases from an internal combustion engine wherein the crankcase ventilation gases flow through an oil separating element and oil droplets contained in the stream are separated in the oil separating element, wherein a volume stream of the crankcase ventilation gases is divided into at least two partial volume streams, and at least one of said partial volume streams is guided through at least one said oil separating element, wherein a size of each of the at least two partial volume streams is controlled depending on a magnitude of the volume stream.
An apparatus for de-oiling crankcase ventilation gases flowing in a volume stream from an internal combustion engine comprising:
- at least two oil separating elements arranged downstream of the internal combustion engine to receive at least a portion of the volume stream;
- at least one control element, through which at least a part of the volume stream is directed, arranged upstream of and in communication with at least one of the oil separating elements, to control a portion of the volume stream directed to the at least one of the oil separating elements, depending on a magnitude of the volume stream.
