Definitions

  • the present invention relates to a gas dynamic pressure wave machine according to the preamble of the claim.
  • catalysts are used in both gasoline and diesel engines in the exhaust system.
  • gasoline engines these consist of ceramic filters coated with catalyst materials, for example platinum powder. This reduces the emissions of pollutants in the exhaust gases, such as carbon monoxide, unburned hydrocarbons and nitrogen oxides.
  • pollutants such as carbon monoxide, unburned hydrocarbons and nitrogen oxides.
  • the most common exhaust gas catalysts are so-called three-way catalysts, ie NO is reduced to N 2 , CO is oxidized to C0 2 , the oxygen from NO being converted into this compound, and the hydrocarbons are oxidized.
  • These catalysts work with lambda values, ie with excess air values of 1 ⁇ 0.02. A lambda probe is required to adjust the mixture accordingly.
  • Similar catalysts are used for diesel engines, with ceramic or metallic support materials also being used.
  • the task of the diesel engine is pure oxidation, because a reduction is not possible due to the excess air.
  • a catalytic converter therefore has the task of burning carbon monoxide, hydrocarbons and soot.
  • soot particle filters are used in diesel engines to reduce the soot impact, which can also be catalytically coated in order to reduce the ignition temperature of the soot that has accumulated and thus burn the soot particles. Filter regeneration can then be achieved.
  • the exhaust gas emission is also influenced favorably.
  • the three-way catalytic converter When charging a gasoline engine with a gas-dynamic pressure wave charger, the three-way catalytic converter must be arranged on the high-pressure side, since the excess air in the low-pressure exhaust pipe can reach very high values as a result of flushing the cellular wheel of the pressure wave charger and thus the condition for the lambda value l Z 0.02 is not to be met. Furthermore, when the catalyst is arranged in the low-pressure exhaust, its back pressure rises sharply, so that adequate flushing of the cells of the cellular wheel would not be ensured.
  • the supercharger can also perform the function of a catalyst for exhaust gas detoxification. It can take over the oxidation effect alone or in addition to a conventional catalyst.
  • the three-way catalytic effect in the cell rotor is not possible, the reduction from NO to N 2 is not possible due to the excess air.
  • the catalytic effect of the rotor satisfies the oxidation requirements of the diesel engine; in the gasoline engine, it only meets the pure oxidation requirements.
  • 1 denotes the hub of the cell wheel of a pressure wave machine, which is formed from individual cells 2 that conduct the air and gas flow and which are encased on the outside by a jacket 3.
  • the surfaces of the individual cells 2 surrounded by exhaust gas and air are coated with a catalyst material 4 known per se, for example platinum or rhodium.
  • a surface-enlarging ceramic underlayer is applied to the metal rotor in a conventional manner, to which the actual catalytic material is then applied.
  • the surface area can also be increased by increasing the number of cells and / or the number of floods . of the rotor.
  • the cellular wheel 1 In an embodiment of the cellular wheel 1 according to FIG. 2, it consists of a ceramic material.
  • the catalyst material 4 can be sprayed onto the ceramic cells 2 either before the cellular wheel 1 is fired or only after the firing process in an additional operation.
