Proposal to update the on-board diagnostics (OBD) requirements, to delete the definition of “vehicles designed to fulfil specific social needs” in line with the Euro 6 stages of European Union Regulation (EC) No. 715/2007 and implementation Regulation (EC) No. 692/2008, and to clarify the wording of transitional provisions and align them with the General Guidelines for UN Regulatory Procedures and Transitional Provisions in UN Regulations (ECE/TRANS/WP.29/1044/Rev.1). In addition, the proposed wording would allow Contracting Parties not to accept UN type-approvals if the requirements specified in the 07 series of amendments are not met.

3 Feb 2015 2016-07-13 11:01:44 UTC 4 4 06 series of amendments | Supplement 4 Based upon the adopted proposal: WP.29/2014/40

Proposal to align the regulation with the full requirements for vehicles that meet “special social needs” under the regulatory framework of the European Union. In response to the extension of the scope of Euro VI legislation down to 2380 kg vehicles, this proposal would also add an exemption to take into account overlap between UN R83 and UN R101 with regard to light-duty vehicle CO2 emissions and fuel/energy consumption. This proposal was adopted by the Working Party on Pollution and Energy (GRPE) at its 68th session based on document GRPE/2014/3, as amended by para. 25. of the session report and document GRPE/2014/7, not amended.

UN R83 | Revision 5 | Amendment 4 (2017)
26 Jul 2017 2017-09-08 11:46:30 UTC 5 4 07 series of amendments | Supplement 4 Based upon the adopted proposal: WP.29/2016/109

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.
