A method and apparatus for vaporizing liquid fuel. Each component is powdery or finely granulated and includes at least one powdery or finely granulated active agent or additive having a higher dosage than the desired concentration for the application. The flexible pouch includes a gusset with a bottom surface. The decreased usage of the cooling system reduces energy consumption and increases vehicle driving range. According to the invention, a slide element is arranged in the recess in such a manner that it abuts on a radial and an axial abutment surface. A charged particle reference beam is directed to a selected TSV within a first net and a charged particle primary beam is then rastered across the TSVs in the first net.
