| description | The European Commission is developing legislative proposals for Euro 7 emissions regulations for light- and heavy-duty vehicles. The new regulation will likely focus on ensuring the emissions from heavy-duty vehicles are minimized over extensive on-road operating conditions, in particular urban driving and cold-start operation. The vehicles will need to achieve low secondary emissions like NH3 and N2O as well. The paper outlines the ultra-low pollutant emissions achieved by a heavy-duty diesel demonstrator vehicle. The Euro VI long-haul truck is equipped with an innovative layout of state-of-the-art emission control technologies, combined with active thermal management. The new emissions control system integrates a close-coupled DOC including an electrically heated catalyst (EHC), a catalyzed DPF, dual-SCR system - one in a close-coupled position -, with twin AdBlue® dosing controlled by FEV-developed software. Both SCR catalysts contain an ammonia slip catalyst. The innovative system layout allows ultra-low NOx emissions and well controlled secondary emissions in even the most challenging conditions with minimal impact on CO2 emissions. Pollutant emissions were evaluated over a broad range of operating conditions, the testing was conducted with a single payload of 10% to show the emissions reduction potential. |
