Beginning mid-2008, a vehicle will be sold on the US market that complies with the exhaust emission standards Tier 2 Bin5: the VW Jetta. This objective was achieved by applying modifications to the Euro 5 Common-Rail engine already available in Europe for the VW Tiguan and the Audi A4 and by introducing the NOx exhaust gas after treatment system. The previous article provided information on the optimisation of the injection system and on the implementation of low-pressure exhaust gas recirculation and cylinder pressure control. These measures have a decisive impact on the improvement of the raw emissions, on the reduction of the emission range and on the reliability of the engine’s operating procedure. The following article discusses the development of the NOx exhaust gas aftertreatment system and the new operating-mode control for overall system management and also describes the OBD functions.
