Abstract: A method and a system for determining a fuel consumption of a vehicle. The method comprises determining a fuel consumption based on a consumption-dependent variable and based on at least one standard value of a fuel material property. The method further comprises determining a fuel material property of the fuel used by the vehicle, calculating a correction value based on the determined fuel material property, and determining a corrected fuel consumption based on the determined fuel consumption and the correction value. In particular, the net CO2 emission or the greenhouse gas emission can be determined from the renewable share.

Abstract: A fuel injection valve for an internal combustion engine includes a valve body having a valve seat face. A valve member has a valve sealing face that interacts with the valve seat face for forming a sealing cross section. The valve member is displaceable along an axial direction in the valve body. The valve body has a wall with injection holes formed therein which are provided downstream of the sealing cross section as seen in a fuel flow direction. The injection holes are coneshaped injection holes and at least two of the injection holes have different cone angles.

Abstract: A toothed belt drive or chain drive has at least one toothed gear wheel and at least one toothed belt or chain. At least one tooth of the toothed gear wheel and/or at least one tooth of the toothed belt or at least one link of the chain has a flank geometry which is different from that of each of the other teeth.
