Abstract (en)

[origin: WO2005106216A2] Disclosed is an internal combustion engine in an operating gear, comprising an oil reservoir (6) for holding oil in the area of a crankcase (10). An oil gauge (12) is used for detecting oil contained in the oil reservoir (6) and generating a corresponding signal which is evaluated in an evaluation unit (13) so as to generate a piece of oil level information. Preferably, said piece of oil level information is generated only when starting the internal combustion engine or for a certain period of time following starting of the internal combustion engine. Once the internal combustion engine has reached its operating speed, the oil level is no longer monitored.
