Proposal for Supplement 8 to the 06 series of amendments to Regulation No. 83
UN Regulations Nos. 49 and 83 include provisions for a “driver inducement system” that alerts drivers of low reagent levels (urea, etc.) critical to correct emissions control performance and eventually prevents vehicle operation if the reagent tank is empty. Under UN R49 (para. 5.2), rescue, police, and other emergency/special use vehicles are exempted from this requirement. This proposal would extend the same treatment under UN R83. The proposal also makes several corrections and clarifications (see document GRPE/2016/11) with respect to extensions of approval, reduction in efficiency of the catalytic converter with respect to emissions of NMHC and NOx, and OBD.
This proposal (WP.29/2016/108), No, was adopted by the World Forum. Thirty-seven Contracting Parties out of the 47 applying UN R83 were present for the vote by AC.1. Thirty-seven voted in favor with zero against and zero abstaining.
