A wall film can form around a temperature sensor as a result of the temperature sensor being fitted in the intake port of the internal combustion engine, in such a manner that at least some of the fuel jet from the injection valve is sprayed onto it. The reduction in temperature that occurs as a result of the enthalpy of vaporization at the temperature sensor is measured and used as a criterion for determining the quality of the fuel supplied to the internal combustion engine. This information can be used to correct the change in injection time exclusively or in addition to adapting the starting quantity and/or using the lack-of-smoothness method.
