Definitions

  • the invention relates to a method for fractionating motor fuel on board a motor vehicle.
  • the object of the invention is a method for separating a low-boiling Fuel fraction from a motor fuel on board a motor vehicle to create, for its implementation only a small volume and a low building weight is required.
  • the required low-boiling Fuel fraction already available when the vehicle is started stand.
  • the invention solves the above object by fractionating the fuel by means of a gas feed pump by vacuum evaporation with subsequent Pressure condensation takes place.
  • the process can be done at ambient temperature be carried out. There is no additional heat or heat dissipation needed.
  • the separated low-boiling fuel fraction is particularly suitable as Motor fuel, with a reduction in hydrocarbon emissions can be reached during the cold start phase of the engine.
  • the separated low-boiling fuel fraction can be used as a reducing agent used for denitrification catalysts in lean engine exhaust will.
  • the fractionation of the fuel can both from the fuel tank of the motor vehicle or from an additional intermediate container respectively.
  • the higher boiling remaining after the separation Fraction in suitable engine operating phases as engine fuel be used.
  • the method according to the invention is suitable on the basis of the advantages mentioned for use in all mobile systems, such as passenger and commercial vehicles.
  • the equipment required to carry out the method is low. On complex Components such as evaporators can be omitted. Hence can Construction volume and weight can be kept small.
  • Another important advantage of the method according to the invention is in that the desired fuel fraction due to the available in the motor vehicle electrical power to operate the gas feed pump immediately at Start of the engine can be provided.
  • the need for one is eliminated Storage tanks for the obtained fuel fraction.
  • the method according to the invention can in particular at ambient temperature be carried out.
  • the suction side of the gas feed pump can also be heated and / or the pressure side of the gas feed pump are cooled.
  • Fig. 2 shows the composition of a with the inventive method obtained low-boiling fuel fraction (hatched bars) in the Comparison of the composition of the starting fuel before separation.
  • the boiling points of the individual components are given in brackets.
  • the pressure on the suction side was 100 to 300 mbar, on the pressure side 1 to 2 bar. 2 shows, low-boiling components highly enriched, while higher-boiling fuel components (including aromatics) are almost no longer included.
