Abstract
A device is provided for improving the measuring accuracy of a process for determining the alcohol content and/or the calorific value of fuels by measuring the electrically measurable qualities of fuel. At least one component of the fuel system of an engine is used with a counterelectrode for the capacitive dielectric measurement of the fuel. At the same time, it is suitable to also use a component of the fuel system with respect to a counterelectrode for the measurement of the conductivity of the fuel. The same counterelectrode can be used for the dielectric measurement and for the measurement of conductivity of the fuel.
