摘要： Values for a raw NOx concentration of an internal combustion engine, that are stored on an operating point basis, are read out from a characteristic map and an adaptation of variations in concentration takes place on the basis of an output signal of an NOx sensor provided downstream of a NOx storage catalyst, either by modification of a reduction factor, which serves for the calculation of a corrected raw NOx concentration from the raw NOx concentration, or by direct correction of the values read out from the characteristic map for the raw NOx concentration with a raw concentration correction factor.

摘要： The present invention includes a method and apparatus for cleaning exhaust of an internal combustion engine. The internal combustion engine has a catalyst and a lambda probe disposed in an exhaust gas tract. The lambda probe is disposed upstream from the catalyst, and is capable of an output &lgr;o substantially close to lambda=1. The present invention includes determining a relationship between a downstream NOx concentration and a lambda value such that a lambda value substantially greater than 1 indicates a substantially greatly increased NOx concentration, and determining a relationship between a downstream NH3 concentration and a lambda value such that a lambda value substantially less than 1 indicates a substantially greatly increased NH3 concentration.

摘要： In a method for regenerating a NOx storage catalytic converter disposed in an engine exhaust operating with air excess, in operating ranges, the improvement includes storing NOx in the exhaust gas in the converter in a storage phase and catalytically converting the stored NOx in a regeneration phase. The signal of the NOx sensor disposed downstream of the converter is detected in the operating range of the overrun fuel cut-off and an average/minimum value is formed from the individual measured values. The average/minimum value is stored as an offset value of the sensor signal. In operating ranges beyond the engine overrun fuel cut-off, the signal of the NOx sensor is detected and the offset value is taken into account when the signal is processed further, in that the offset-corrected signal is compared with a threshold value. In the event that the threshold value is exceeded, a regeneration phase of the converter is initiated.

摘要： There is described a method for determination of an application time for a tank ventilation on an internal combustion engine. An excessive enrichment of the air/fuel mixture can be avoided by means of a timely application of injection correction as result of the tank ventilation. According to said method, a threshold value comparison is carried out for a modified lambda control deviation, made up of the lambda control deviation and a pseudo lambda control deviation, whereby the pseudo lambda control deviation depends on the deviation of the lambda values from a given lambda set value.
