Abstract:
A method for identifying the fuel quality and for operating an internal combustion engine, as well as an engine control unit, in which the temperature of at least one sheathed-element glow plug of the engine is controlled, an engine response after a temperature change is compared to an engine response before the temperature change, and from the result of this comparison, the fuel quality is derived.
