20080289401METHOD TO DETERMINE A FUEL COMPOSITION - The invention concerns 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, wherein the first and the second fuel have different combustion rates and/or different specific energy contents and wherein 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. Provision is made according to the invention for the composition of a fuel mixture to be determined from the temporal pressure curve and/or the pressure curve under conditions of angular synchronism of the gas pressure in the combustion chamber, of which there is at least one. A fuel mixture from fuels with different combustion rates exists, for example, in an alcohol-gasoline mixture. Alcohol has a faster combustion process than gasoline. For that reason, the proportion of alcohol in the fuel mixture can, for example, be suggested from the time difference between ignition and maximum pressure in the combustion chamber. The method according to the invention has the advantage, in that the alcohol content can already be determined shortly after cold starting the engine, if a method based on the signal of a lambda probe can not yet be executed because the lambda probe has not yet achieved its operating temperature. It is also particularly advantageous, in that the influence of the alcohol proportion in the fuel mixture can be separated from the errors of the fuel mixture generation, which result from the air and fuel pathways. This is otherwise only possible when using a cost inflating alcohol sensor. Furthermore, the method according to the invention can be implemented in one or in a small number of combustion cycles, while methods based on the signal of the lambda probe require a significantly longer time period. The method can be employed in internal combustion engines, which have a pressure sensor in at least one combustion chamber. Provision can, however, be made for the method to be used in selected or in all of the cylinders of the internal combustion engine.11-27-2008
