A method for determining a soot concentration in an engine oil of internal combustion engines, in which method a defined quantity of the engine oil is conducted with a defined flow speed along and/or through a measurement path. In a region of the measurement path, the engine oil is acted on with energy from at least one energy source in such a way that the soot particles contained in the engine oil at least partially absorb the energy. An energy quantity absorbed in the measurement path region is subsequently detected, and from this a soot concentration in the engine oil is determined. A device for determining the soot concentration in the engine oil of internal combustion engines is provided for performing the method. |
