摘要： The present invention relates to a process for determining the state of an exhaust-gas purification device. The exhaust-gas purification device is one which can store gas and/or particles. By means of the proposed process, it is for example possible for the loading state of the exhaust-gas aftertreatment system, for example the oxygen storage state of a catalytic converter which is provided with an oxygen-storing material, such as for example a three-way catalytic converter, to be analysed. The present process operates contactlessly through the analysis of resonances which arise upon the excitation of the catalytic converter using the purification device as microwave cavity resonator

摘要： The invention describes a method for determining the light-off temperature of a catalytic converter on board a vehicle. The aging condition of the catalytic converter is determined by means of the method. To test the catalytic converter, the latter is loaded for example with a CO/HC test pulse. During the combustion of the additional CO and HC on the catalytic converter, an axial temperature profile is generated. The position of the maximum of said temperature profile along the catalytic converter is dependent on the current light-off temperature. The temperature profile travels through the catalytic converter and can be measured at the outlet of the catalytic converter as a time-dependent profile. The original axial temperature profile can be inferred from the time-dependent profile. Using a calculation program, the current light-off temperature of the catalytic converter on the vehicle can be determined. The method has the advantage that the test can take place at exhaust-gas temperatures considerably higher than the light-off temperature. In this way, it is ensured that the test pulse does not lead to increased pollutant emissions.

摘要： The present invention relates to a method for purifying the exhaust gases of an internal combustion engine having a catalytic converter which comprises oxygen storage components. The invention is concerned particularly with the restoration of the optimum filling degree of the oxygen storage components for regulated stoichiometric operation after the engine has been operated under lean conditions for a relatively short or relatively long period of time.

摘要： When a nitrogen oxide storage catalyst is being regenerated, the regeneration may be terminated for example as a result of a premature load change in the engine, which can lead to incomplete emptying of the storage catalyst. The residual filling level which remains in the catalyst following an incomplete regeneration of this nature is used as the starting value for calculation of the filling level during the next storage phase. After incomplete regeneration, the nitrogen oxide conversion rate is initially greater than would be expected, on account of the residual filling level. By taking this increased conversion rate into account when calculating the filling level during the storage phase, it is possible to further improve the accuracy of the calculation.

摘要： A cost effective process is presented for carrying out catalytic, in particular also exothermic, endothermic or autothermal reactions with optimum yield and selectivity. The system used is a wall-flow monolith which forces a flow from the inlet channel through the porous wall into the outlet channel by reciprocal closure of the gas channels. This is operated such that mass transfer and heat transport are determined virtually exclusively by convection, and diffusion-related thermal conduction phenomena can be neglected.
