    摘要: A particle separator and method for removing particles from an exhaust gas stream of an internal combustion engine. A prescribed number of flow cells are formed in the particle separator. The exhaust gas stream flows into and/or out of the flow cells via, as viewed in a main direction of flow of the exhaust gas stream, side wall regions of the flow cells. At least one storage space is formed in the flow cells for storing particles removed from the exhaust gas stream, which flows through at least portions of the particle separator.

    摘要: The process and apparatus according to the invention allow the production of hydrocarbons and ammonia without the use of catalysts. For this purpose, waste gases containing CO2 or N2 from an upstream process are fed to compression reactors. In addition, hydrogen from an electrolyzer is fed to these reactors to enable hydrogenation of the fed substances. Methane, alcohols and ammonia, for example, can be produced by this process. In order to increase the yield of the process, it is planned to raise the reactant pressure with the aid of a compressor.

    摘要: An arrangement and method for reducing the nitrogen oxide content in the exhaust gas of an internal combustion engine with the aid of ammonia and/or ammonia-releasing reduction agents, whereby ammonia and/or ammonia-containing reduction agent is added to the exhaust gas stream upstream of a catalyst combination composed of an SCR catalyst and a subsequent NH3-oxidation catalyst in such a way that a homogeneous mixture of exhaust gas and ammonia is present upstream of the SCR catalyst. To optimize the reaction or conversion of nitrogen oxides, disposed downstream of the combination of a first SCR catalyst and a first NH3-oxidation catalyst is at least one second catalyst having SCR activity in order in this way to reduce the nitrogen oxides formed at the first NH3-oxidation catalyst due to insufficient selectivity of the catalyst to nitrogen with not yet oxidized NH3.

    摘要: A method for determining a deviation of a fuel quality from a reference quality and for determining a change in exhaust gas emissions caused by this deviation by evaluating pressure waves in a fuel system of an internal combustion engine outfitted with one of a discontinuous fuel delivery and a fuel take-off. The method includes detecting pressure oscillations in the fuel system during operation by at least one sensor; determining at least one of a fuel type and the deviation from a reference fuel quality by analyzing the detected pressure oscillations in an electronic monitoring unit; and at least one of changing behavior of an exhaust gas aftertreatment system downstream of the internal combustion engine based at least in part on deviations of the untreated emissions of the internal combustion engine from the untreated emissions occurring when using the reference fuel, changing service intervals when a deviation from the reference fuel quality is determined, changing engine oil change intervals are changed when a deviation from the reference fuel quality is determined displaying information about use of a fuel deviating from the reference fuel is, displaying the changed service interval, changing operating parameters of the internal combustion engine, and changing operating parameters of the exhaust gas aftertreatment system downstream of the internal combustion engine.

    摘要: An exhaust gas post treatment system for nitrogen oxide and particle reduction of internal combustion engines operated with excess air. An oxidation catalytic converter is disposed in the exhaust gas stream of the engine for converting at least a portion of the nitric oxide in the exhaust gas into nitrogen dioxide. The first particle separator or filter is disposed in the exhaust gas stream downstream of the oxidation catalytic converter for converting carbon particles accumulated in the separator or filter into carbon monoxide, carbon dioxide, nitrogen and nitric oxide with the aid of nitrogen dioxide contained in the exhaust gas. A partial exhaust gas stream is branched off from the exhaust gas stream upstream of the first separator or filter. A metering device adds reduction agent to the partial exhaust gas stream in the form of ammonia or a material that releases ammonia downstream of the supply location due to hot exhaust gas. A second particle separator or filter is disposed in the partial exhaust gas stream downstream of the supply location. The partial exhaust gas stream returns to the exhaust gas stream downstream of both particle separators or filters. An SCR catalytic converter is disposed downstream of the return location for reducing nitrogen oxides in the exhaust gas to nitrogen and water vapor with the aid of ammonia or released ammonia by way of selective catalytic reduction.
