W praktyce kiedy spełniamy warunki do wypalenia siarki z katalizatora NOx? Jak długo i jak dynamicznie trzeba jechać? edit: Dla N43 http://www.bmw-planet.com/diagrams/release/zi_images/GR_FB1207011.png 1 Extended stratified-charge operation: lambda value very much greater than 1 2 Transition range: lambda value almost greater than 1 3 Homogeneous operating range: lambda value = 1 "Non-sulphur fuel contains a minimum of sulphur. The sulphur reduces the storage capacity of the nitrogen oxide catalytic converter. Sulphurisation of the nitrogen oxide catalytic converter means that the engine is only operated with homogeneous mixture, as no nitrogen oxides can be absorbed. The engine management system detects the sulphurisation of the nitrogen oxide catalytic converter. For desulphurisation, the nitrogen oxide catalytic converter is heated to 600 °C to 650 °C and operated with a rich mixture (lambda value = 0.94). The following vehicle operation is necessary to actively heat up the nitrogen oxide catalytic converter: Driving speed greater than 110 km/h for 25 minutes Fuel gauge higher than 50 % In the event of a fault code memory entry (NOx catalytic converter sulphurised), more frequent heating-up can be activated using a service function. This enabling remains active until the nitrogen oxide catalytic converter has been successfully desulphurised. No liability can be accepted for printing or other errors. Subject to changes of a technical nature" Zastanawia mnie ten wymóg 50% zbiornika paliwa. Czyżby w zbiorniku odkładała się siarka?
