Summary

The Corporate Average Fuel Economy (CAFE) regulation demands for a continuous fuel consumption reduction of light-duty vehicles in the US. As light-duty vehicles operated with diesel engines provide higher fuel efficiencies compared to gasoline vehicles and higher cruising ranges than electric vehicles, an increase of the diesel market share would help to meet the US market´s requirements. However, the emission limits for nitrogen oxides and nonmethane organic gas (NO_x + NMOG) have to be concurrently reduced below levels, which can be achieved with today´s production technologies for diesel emission concepts. In this study, an advanced exhaust gas aftertreatment concept is developed for a Jaguar XF E-segment vehicle with an I4 2.2l diesel engine to meet the emission standards for super ultra low emission vehicles, SULEV.
