Abstract
In a fuel supply system for an internal combustion engine having a fuel tank for liquid fuel, a fuel pump which draws fuel from the fuel tank and pressurized the fuel to an injection pressure at which the fuel is made available to the internal combustion engine, a fuel-fractionating device which produces at least one liquid fuel fraction from the fuel, and an accumulator which receives the liquid fuel fraction from the fuel-fractionating device, stores it and makes it available to the internal combustion engine, the fuel fraction made available and the fuel made available being fed to the internal combustion engine by the fuel supply system as a function of demand, the accumulator is a pressure accumulator and includes pressure-generating means for pressurizing fuel fraction in the pressure accumulator to the injection pressure.
