Abstract
A method to determine the fuel composition of a fuel mixture from a first fuel and a second fuel for the operation of an internal combustion engine. The first and the second fuel have different combustion rates and/or different specific energy contents and the internal combustion engine has at least one pressure sensor in at least one combustion chamber, with which a temporal pressure curve and/or a pressure curve under conditions of angular synchronism is determined.
