In a fuel supply system, at least one of a first negative pressure P1 and a second negative pressure P2 is adjusted such that a width of a negative pressure range P1, P2 of a condenser in a second state, that is, the difference P2\u2212P1 of the first and second negative pressure, becomes smaller as a concentration C2 of high-octane number component of a raw fuel F0 is lower. The planetary gearing includes at least one drive shaft, an output shaft, a sun wheel, a ring gear, planet wheels assigned to the planetary gear train, a gear casing, in particular a multipart gear casing, a planetary gear train, in particular the second planetary gear train, comprising a planet wheel arm immovably arranged in a casing. A derefinement procedure replaces each refinement type with a dependent pair type corresponding to the proof. The integrated circuit further comprises at least one packet inspecting unit for inspecting bits of said at least one packet to determine bits not required for said issued transaction and for matching said not required bits of said at least one inspected packet with other bits of the same packet. At least two such indicators are combined in order to detect the presence of an object within the detection zone and with changing range gates in each of the antenna beams the coverage of the detection zone can be varied.
