Abstract:
A fuel supply system for an internal combustion engine, having a fuel tank for liquid fuel, a fuel pump for withdrawing fuel from the fuel tank and pressurizing the fuel to an injection pressure for supply to the internal combustion engine, a fuel processing device which produces at least one liquid fuel fraction from the fuel, and an accumulator to which the liquid fuel fraction from the fuel-processing device is supplied to be stored therein and from which it is made available to the internal combustion engine by the fuel supply system as a function of demand, and pressure generating means for the fuel fraction in the pressure accumulator, said pressure-generating means comprising a bellows arranged in the pressure accumulator and a pressure source connected to the bellows supplying the injection pressure of said fuel to said bellows for pressurizing said accumulator.
