Abstract
A method for determining the Ethanol content of the fuel in a motor vehicle uses the dependence of the lean-running limit of the internal combustion engine on the ethanol content of the fuel to determine the ethanol content, by the fact that the ethanol content is arrived at from the required reduction in the injected fuel quantity to reach the lean-running limit.
