    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： The invention relates to a process for preparing a Pt/zeolite catalyst material, the material itself, and the use of the material in removing carbon monoxide from a gas. In a preferred embodiment, the invention relates to a process for preparing a Pt/zeolite catalyst material for the catalytic removal of CO in H.sub.2 -rich gas by means of selective CO oxidation and the use of such a catalyst material. The catalyst materials of the invention can be prepared by employing Pt(NH.sub.3).sub.4 Cl.sub.2.H.sub.2 O and a zeolite material. The resulting material can be used for the catalytic removal of CO from an H.sub.2 -rich outlet gas mixture from a methanol reforming reactor. The compositions and methods to produce catalytic materials result in products with high and prolonged catalyst activity. In particular, the methods and compositions of the invention can be used in removing CO from the hydrogen fed to fuel cells in electric vehicles having stored methanol fuel.

    摘要： An Ag-containing solid, such as Ag2O, Ag2CO3, and AgOH, is used for storing/releasing nitrogen oxides in an exhaust gas from an engine during controlled cycling of the &lgr;-value of the exhaust gas. The nitrogen oxides are stored at &lgr;-values of the gas greater than 1 in the Ag-containing solid and the nitrogen oxides are released at &lgr;-values of the gas less than or equal to 1 from the Ag-containing solid. The Ag-containing solid may include a precious metal or a microporous carrier, for example, ZrO2, SiO2, TiO2, Si—Al mixed oxide, and zeolites.

    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.
