  • Device and method for venting a crank casing of an internal combustion engine
    Patent number: 10443460
    Abstract: The invention relates to a device for venting a crank casing of an internal combustion engine for a vehicle, having a plurality of venting ducts (13, 15, 53, 67, 84) by means of which gases flowing into a crank casing space (19) of the crank casing (7) can be conducted out of the crank casing space (19) again, wherein gas inlet openings (29, 55, 73), opening into the crank casing space (19), of the venting ducts are arranged in such a way that in a first defined inclination position of the internal combustion engine (3) a first venting duct does not dip with its gas inlet opening (29) into oil trough oil which is collected in an oil trough (5) of the internal combustion engine (3), and a second venting duct dips with its gas inlet opening (29, 55, 73) into the oil trough oil, wherein in a second defined inclination position of the internal combustion engine (3) which differs from the first inclination position the first venting duct (13, 67) dips with its gas inlet opening (29) into the oil trough oil and the
