Proposal to adapt the 06 and 07 series of amendments to Regulation No. 83 to Selective Catalytic Reduction (SCR) warning and inducement systems to current vehicles, emissions requirements and reagent infrastructure. In light of further vehicle weight reduction for CO2 optimization and the resultant vehicle packaging challenges, diesel cars will likely have smaller AdBlue® reagent tanks. For passenger cars, the warning indicator to refill AdBlue® has to be activated at 2,400 km of remaining reagent range which could result in very frequent refills of smaller reagent tanks. This proposal would allow for reagent refill inducement warnings as a percentage of tank capacity. For heavy-duty vehicles, the warning has to be activated at least at a reagent level of 10 per cent of total reagent tank volume. The inducement system has to be activated at least at 2.5 per cent of reagent level.

10. The expert from OICA withdrew ECE/TRANS/WP.29/GRPE/2017/5 on amendments to Regulation No. 83 to adapt the provisions on selective catalytic reduction warning and inducement systems to current vehicles, emissions requirements and reagent infrastructure. He mentioned that this is an urgent topic and that differences between European legislation and UN Regulations should be minimized. He announced his intention to address this topic first at the European level, and he invited all stakeholders to contribute to the discussion since the beginning.
