Definitions
- the invention relates to a method for desulfurizing a NO x storage device in an internal combustion engine according to the preamble of claim 1.
- NO x accumulator in order to reduce the environmental impact and are then regularly eliminated in a regeneration process in the case of a rich mode of operation of the internal combustion engine.
- NO x sensor can be used to identify the nitrogen oxide load in the storage and thus to control the regeneration process.
- suitable models can also be used to infer the sulfur loading of the NO x storage.
- a sulfur loading model is conventionally used to assess the extent of sulfur storage in the NO x storage, the sulfur loading model usually being designed in such a way that an artificial, sufficiently early desulfation is requested and carried out, even for predominantly short distances and in urban use becomes.
- the object of the present invention is a method of the aforementioned Provide species with a desulfation that meets the needs.
- a normal model calculation as is already known from the prior art used.
- the knock signal or the knock control which is in the engine control in is present in most cases, evaluated and a knock sensitivity of the Fuel determined.
- the amount of fuel used, determined and evaluated in particular during lean operation. On fuel consumption can be done, for example, by evaluating the injection processes or close the tank level evaluation.
- Size can be determined, which is included in the model calculation and so affects that with a fuel with a high tendency to knock in shorter intervals desulfation is carried out. For a fuel with one less With a high tendency to knock, the desulfation intervals are selected further apart.
- a map there is a relation between the knock sensitivity and the sulfur concentration in the fuel, depending on the tendency to knock deduces the sulfur concentration.
- the present invention thus allows a simple and very inexpensive way perform a needs-based adaptation of the desulfation steps.
