Abstract (en)
[origin: WO2010075935A1] The invention relates to a method for operating an internal combustion engine having a crankcase, a crankcase vent, and a vacuum system. According to the invention, the pressure in the crankcase can be reduced as a function of a differential pressure between the vacuum system and the crankcase to a maximum of -500 mbar, particularly a maximum of -300 mbar, relative to the ambient pressure, for reducing lubricant consumption of the internal combustion engine.
