    摘要: A process is provided for drawing low-boiling volatile components, such as 2-methylbutane, 2,3-dimethylbutane and pentane, out of fuel in a fuel tank of a passenger car or utility vehicle by applying a vacuum to the fuel tank by means of a diaphragm pump; suctioning off the low-boiling volatile components and condensing the low-boiling volatile components under a pressure that is greater than 1.0 bar. The low-boiling volatile components may be stored in a storage tank and used as engine fuel during cold start of the engine or used as a reducing agent for nitrogen oxides in the exhaust gas from the engine.

    摘要: 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.
