CO2 REduction for long distance transport

CORE –


Chris Such, Ricardo On behalf of CORE Project Coordinator Johan Engstrom, Volvo




CORE Vision

CO2RE focus is on highly efficient drivelines for long distance transport with a target of 15% reduction in CO2 Development of innovative and competitive solutions for HD engines with a

market introduction target before 2020 Development of engine technologies able to integrate the contribution

coming from electrification or the use of alternative/renewable fuels.

SPA2 High efficiency Diesel engine for long haul




• New boundary conditions

– Higher PCP

– Variable valve actuation (VVA)

– Highly efficient two-stage turbo

– Highly efficient aftertreatment system

• Allows for new combustion system & new advanced combustion strategies with reduced emissions of CO2

– Development of Miller (late or early) cycle as a combustion strategy

– Down speeding

– Improved NOx- soot trade off yielding improved efficiency

Main targets and objectives

• Goal: Investigate opportunities to enable CO2 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.

• CO2 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 CO2 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
