Proposal to correct the inadvertent deletion of a sentence in by WP.29/2015/57 adopted at the 166th session of the World Forum for Harmonization of Vehicle Regulations (WP.29).

Proposal to clarify that no more than four malfunction-indicator failures shall be simulated for type approval.

Proposal from the European Commission to provide clarifications and correct errors in the 06 series of amendments to Regulation No. 83.

Proposal from the European Commission to provide clarifications and correct errors in the 07 series of amendments to Regulation No. 83.

Tyre rolling resistance falls outside the scope of UN R0 because this attribute is used in the calculation of C02 emissions and IWVTA does not include UN R83 or UN R101.

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.

Proposal from the European Union to provide clarifications and correct errors in the 06 and 07 series of amendments to Regulation No. 83.

Proposal to correct the calculation of the coast-down resistance to progress force.

Proposal to correct the calculation of the coast-down resistance to progress force.

Presentation on the background and accomplishments of the GFV informal group from January 2008 to June 2016 as the group concludes its final effort on heavy-duty dual fuel engine retrofit systems.

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.

Proposal to allow the use of compliance assessments of vehicles with a reference mass less than 2,610 kg in extending the type approval to special purpose vehicles (including armoured ones) having a reference mass exceeding 2,840 kg. This proposal would align UN R83 with provisions of European Directive 2007/46/EC.

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.

During the 169th session of WP.29 (para. 39 of the session report), the World Forum was informed that, following the entry into force of the new European legislation on provisions on real driving emissions and Worldwide Harmonized Light Vehicle Test Procedure (WLTP) as of September 2017, no new vehicles will be allowed to enter into the European market without fulfilling these new provisions.

WP.29 agreed to introduce transitional provisions in UN Regulations Nos. 83 and 101 to specify that Contracting Parties applying UN Regulations Nos. 83 and 101 which would also apply WLTP as defined in UN GTR No. 15 (such as the EU) would have no obligation to accept type-approvals granted on the basis of test cycles other than WLTP as of September 2017 (para. 41 of the 169th session report). WP.29 requested the secretariat to prepare an official document for the WP.29 March 2017 session, subject to the endorsement of GRPE at its January 2017 session, on supplements to UN Regulations Nos. 83 and 101 introducing such transitional provisions.

Thus, the secretariat has prepared this text to allow for such a derogation from mutual recognition requirements under UN R83 and R101 until such time as GTR 15 has been transposed into UN Regulations under the 1958 Agreement.
