Abstract:
An example method for operating an internal combustion engine may include: measuring pressure oscillations for a cylinder in the inlet tract at a defined operating point during normal operation; generating a corresponding oscillation signal; determining a crankshaft phase angle corresponding to the oscillation signal; and from the pressure oscillation signal, using discrete Fourier transformation to calculate the actual phase position of a selected signal frequency; determining a further comparison phase position in the same way from the selected signal frequency in the absence of fuel injection; calculating an actual phase position difference; on the basis of the difference, taking into consideration reference phase position differences of the same signal frequency for different fuel compositions, to identify a fuel composition of the presently used fuel; and adapting operating parameters of the engine based on the identified composition.

Claim (Index 4):
The method as claimed in  claim 15 , wherein the model function has been derived prior to the normal operation from the reference phase position differences of the selected signal frequency and the associated fuel compositions, and replicates the relationship between the reference phase position differences of the selected signal frequency and the fuel compositions.
