Method for determining an alcohol concentration of fuel fed to combustion in a motor vehicle after filling with a fuel of predetermined alcohol concentration

摘要

In the method for determining the alcohol concentration of the tank fuel after filling up with E85 fuel or E0 fuel, two corridors of possible lambda values for filling with E0 fuel and E85 are established according to the volumes of the tank fuel before and after filling, and the lambda values are taken into account in the evaluation.
