摘要： A method and a device are described for filtering a variable. A first filtering arrangement is used for forming an output variable as a function of an input variable, the first filtering arrangement having at least a delaying effect. The input variable of the first filtering arrangement is corrected using a correcting variable which is obtained by starting from the input variable of the first filtering arrangement and by filtering, using a second filtering arrangement.

摘要： Described is a method for controlling a temperature downstream of a catalyst in the exhaust tract of an internal combustion engine including a first control loop in which a first control variable is calculated from a first deviation that is calculated from a first actual value and a first setpoint value and influences an intra-engine heat generation. In the process, the first actual value is determined as a measure of a temperature downstream of the catalyst. The method features a second control loop in which at least one second control variable is calculated from a second deviation that is calculated from a second actual value and a second setpoint value; a temperature upstream of the catalyst being determined as the second actual value. Also described is a controller which controls the sequence of such a method.

摘要： This paper suggests a procedure for the operation of an internal combustion engine, which has a particle filter arrayed to its emission system, which, during regeneration, is cleansed of its stored particles. This also describes the procedure's comparison of the engine's amount of a load to the load threshold value. It also has a throttle cut-off, which suppresses the fuel supply entirely when the engine's amount of a load is lower than the load threshold value and the engine's revolutions are higher the revolution threshold value. The set load threshold value above null is further dependant on the particle filter's regeneration signal. These procedures, based in this invention, are to prevent the overheating of the particle filter during its regeneration.

摘要： A method for operating a sensor for recording particles in an exhaust gas flow and a device for carrying out the method are provided, in which at least one measure of the exhaust gas flow is ascertained and in which the measure of the exhaust gas flow is taken into consideration in the valuation of the particle sensor signal made available by the particle sensor. The procedure is based on the knowledge that the exhaust gas flow, for instance, the exhaust gas volume flow, has an influence on the particle sensor signal made available by the particle sensor, especially when the measuring effect is based on the depositing of particles on a sensor surface. Using the procedure, a possibly present cross sensitivity of the particle sensor with respect to different exhaust gas flows is taken into consideration, so that the measuring accuracy is increased.

摘要： The invention relates to a method and an apparatus for temporarily increasing the temperature in the exhaust gas of an internal combustion engine, comprising at least two associated turbochargers with a respective compressor in a fresh air feed to the internal combustion engine and a respective turbine in an exhaust gas line of the internal combustion engine, wherein a bypass is assigned to at least one compressor and/or one turbine, and comprising at least one exhaust gas retreatment system connected downstream of the turbines in the exhaust gas direction. In this case, the volumetric flow of fresh air and/or of exhaust gas directed past at least one compressor and/or one turbine through the bypasses is increased via regulating elements in the bypasses, which leads to a reduction in the charge pressure and hence to a reduction in the efficiency of the internal combustion engine and to an increase in the exhaust gas temperature.

摘要： A method for operating an internal combustion engine, in whose exhaust region, in the direction of flow of the exhaust gas, there are situated a first broadband lambda sensor which makes available a first lambda signal, an NOx adsorption catalyst and a second broadband lambda sensor which makes available a second lambda signal, in which the NOx adsorption catalyst cyclically stores the NOx emissions of the internal combustion engine, and is regenerated within the scope of a nominal regeneration by the operation of the internal combustion engine using a rich/stoichiometric air/fuel mixture, and a device for carrying out the method are provided. An intensified regeneration, compared to a nominal regeneration, of the NOx adsorption catalyst is undertaken, which supports a better setting of the thermodynamic equilibrium in the exhaust gas compared to the nominal regeneration. At the end of the intensified regeneration, at a still rich/stoichiometric air/fuel mixture, a plausibility check/correction of the first lambda signal using the second lambda signal is provided.
