Main targets and objectives Goal: Investigate opportunities to enable CO 2 reduction using highly integrated SCR subsystem with improved low-temperature NOx reduction performance Background: EURO VI standards require significant NOx reduction, demonstrated in new WHTC cycle that is much colder than previously used ETC High NOx reduction efficiency of aftertreatment system enables a fuel consumption optimised combustion process. CO 2 reduction technology in CORE is expected to reduce exhaust temperatures Therefore, the aftertreatment efficiency must be increased at low temperatures. End result: a NOx aftertreatment system with increased NOx reduction efficiency, delivered to the vertical projects. Component and subsystem development and testing will be supported by numerical simulation models derived from laboratory-scale experimental data.

Technical approaches WP 25. SCR component development Metal oxide (Ce-Zr) SCR formulations Advanced zeolite-based SCR formulations Integration of new SCR formulations on chosen DPF substrates WP 26. Low-temperature AdBlue processing development AdBlue additive for improvement low-temperature activity of SCR catalysts via nitrate delivery to the surface AdBlue processor to enable low-temperature reductant injection WP 24. EAT system integration Assessment / definition of SCR system requirements via SCR system simulation Development of SCR component models: Advanced SCR washcoat and SCR / DPF technology AdBlue additive and AdBlue processor performance System simulation to assess interaction of SCR subsystem with other vehicle systems Development of algorithms & software to control new EAT components

Concluding remarks: CORE will contribute to CO 2 emissions reduction. Good progress has been made towards the target of 15% reduction CORE knowledge and technology will be used in near production (before 2020) CORE started to share information with the parallel NoWaste project on Waste Heat Recovery Next major review of CORE in October 2013
