Abstract
In a fuel fractionation device for separating a low-boiling fuel fraction from a liquid fuel of an internal-combustion engine, including a vessel which contains the liquid fuel, and in which a reduced pressure is generated by withdrawing the low-boiling fuel fraction in vapor form from the vessel and making it available to the internal combustion engine, the efficiency of the fractionation is improved by utilizing a carrier-gas which is introduced into the liquid fuel, and which is withdrawn from the vessel together with the fuel fraction vapor.
