Abstract:
A fuel fractionation device for separating a low-boiling fuel fraction from a liquid fuel of an internal combustion engine, comprising a vessel which contains the liquid fuel, a gas extraction means generating a reduced pressure in said vessel by withdrawing gas and the low-boiling fuel fraction formed by the fuel fractionation device in the vessel from the vessel and making it available to the internal combustion engine, and a carrier gas supply means including a gas distributor arranged submerged in the fuel in the vessel for introducing a carrier gas into the liquid fuel in said vessel thereby enhancing removal of the low boiling fuel from the liquid fuel in sad vessel by said carrier gas as it rises through the fuel, said carrier gas being sucked out of said vessel together with the fuel fraction evaporated from he fuel in the vessel.
