Within the EU funded Horizon 2020 “dieper” project (Diesel engine efficiency improvement and Particulate number Reduction), the authors are working to develop a Light Commercial Vehicle (LCV) demonstrator to enable emissions of 50% of Euro 6 limits and a >80% reduction in particulate numbers including the 10-23nm range. A fuel economy improvement of >5% is also required. The “dieper” project is yet in an initial phase. The paper will outline aspects of a Euro 6b compliant vehicle in the near-future testing environment (RDE, WLTP) with post Euro 6 emissions limits (2020). The baseline vehicle was measured at project start (2017) and the improved vehicle will be measured again the end of the project (2019) by an independent institution (Virtuelles Fahrzeug in Graz, ViF). The paper describes the baseline situation and improvement steps to reach the targets. Hybridization and electrification are excluded from this project and could be added in a further step to meet expected 2025 CO2 regulations.
