Abstract
To monitor adequate oil lubrication of an internal combustion engine, air bubbles in the oil flow are detected by means of a sensor arranged in an oil line of a pressure circulation lubrication system and connected to an electronic evaluation system. These air bubbles are an early indicator of inadequate lubrication of the internal combustion engine.

A method for monitoring adequate oil lubrication of an internal combustion engine, in particular that of a vehicle, by a sensor arranged in an oil line of a pressure circulation lubrication system and connected to an electronic evaluation system adapted to generate a warning signal, wherein gas bubbles in the oil flow are detected by the sensor and the electronic evaluation system, and the electronic evaluation system generates a warning signal when the presence of air bubbles exceeds a predetermined level.
An internal combustion engine with a device for monitoring adequate oil lubrication by means of a sensor arranged in an oil line of a pressure circulation lubrication system and connected to an electronic evaluation system adapted to generate a warning signal, wherein the sensor and the electronic evaluation system are designed to detect gas bubbles in the oil flow and to generate a warning signal when the presence of air bubbles exceeds a predetermined level.
