A fuel dispensing system is provided wherein the fuel is provided only to authorized vehicles through verification of identification information, such as scanning a bar code disposed on the vehicle or fuel storage container. Each of the three segments is formed sequentially adjacent and aligned along an axis of the rotor. Characteristic variables are formed both on the basis of the starting materials or raw materials and of the chemicals, auxiliaries and energy supplied in the successive method steps as well as of the materials and emissions to be disposed of. An epitaxial layer can be grown atop the trenches after planarization, if desired. The permeable port is disposed in at least a part of a region between the central position of the whole length of an air intake duct and the central position of the whole length of the intake air passageway portion.
