Abstract:
An internal combustion engine can be operated by a fuel mixture consisting of a base fuel and an alternative fuel. Concentration values (ETH_PERC) of the alternative fuel are determined in at least two different ways for operating the internal combustion engine. A reliable concentration value of the alternative fuel is determined depending on the various determined concentration values (ETH_PERC).
