Abstract
In a method for operating an internal combustion engine, a crankcase of the internal combustion engine has a vent into the intake section of the internal combustion engine, and upon outgassing of fuel out of engine oil present in the crankcase, the operating point of the internal combustion engine is modified so that the air-fuel ratio does not fall below a definable value.
