GRPE-74-07 | WP.29 highlights for the 74th GRPE session

GRPE/2017/2 | Proposal for a new Supplement to the 06 and 07 series of amendments to Regulation No. 83 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.

GRPE/2017/5 | Proposal for a new Supplement to the 06 and 07 series of amendments to Regulation No. 83 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.

GRPE-74-16 | Proposal for amendments to ECE/TRANS/WP.29/2017/42, ECE/TRANS/WP.29/2017/43 and ECE/TRANS/WP.29/2017/44 The subject documents would permit Contracting Parties applying UN R83 and/or UN R101 and which have transposed GTR No. 15 (WLTP) into their local legislation to refuse to accept type approvals granted under the UN R83 and/or UN R101 as a compliance alternative to their national/regional legislation (i.e., aligned with GTR No. 15). OICA proposes to clarify the intent by deleting allusions to the measure as a form of derogation, to replace the phrase "may no longer accept" with "may refuse", and to introduce a sunset clause to noting that the measure is intended as a stop-gap until such time as GTR No. 15 has been transposed into the corpus of UN Regulations.

GRPE-74-22 | Proposal of changes to document GRPE/2017/2 concerning amendments to Regulation No. 83 Pursuant to GRPE discussions, the proposal adds the following paragraph to the amendment: "At the manufacturer's request, type approval granted under this Regulation may be extended from vehicles mentioned above to special purpose vehicles of categories M1, M2, N1 and N2 regardless of their reference mass. The manufacturer shall demonstrate to the Type Approval Authority which granted the type approval that the vehicle in question is a special purpose vehicle."

WP.29/2017/42 | Proposal for Supplement 9 to the 06 series of amendments to Regulation No. 83 Proposal, subject to endorsement by the GRPE during its January 2017 session, to permit Contracting Parties applying UN R83 and GTR No. 15 (WLTP) to refuse type approvals granted under UN R83 as an alternative to compliance with their national/regional legislation from the date of entry into force of Supplement 9 to the 06 series of amendments to UN R83.

WP.29/2017/43 | Proposal for Supplement 5 to the 07 series of amendments to Regulation No. 83 Proposal, subject to endorsement by the GRPE during its January 2017 session, to permit Contracting Parties applying UN R83 and GTR No. 15 (WLTP) to refuse type approvals granted under UN R83 as an alternative to compliance with their national/regional legislation from the date of entry into force of Supplement 5 to the 07 series of amendments to UN R83.

WP.29/2017/44 | Proposal for Supplement 7 to the 01 series of amendments to Regulation No. 101 Proposal, subject to endorsement by the GRPE during its January 2017 session, to permit Contracting Parties applying UN R101 and GTR No. 15 (WLTP) to refuse type approvals granted under UN R101 as an alternative to compliance with their national/regional legislation from the date of entry into force of Supplement 7 to the 01 series of amendments to UN R101.

GRPE/2017/3 | Proposal for a new GTR on evaporative emissions test procedures under the Worldwide harmonized Light vehicles Test Procedure (WLTP EVAP) Text prepared by the Evaporative emissions Task Force of the WLTP informal working group in line with Phase 2 of its mandate (ECE/TRANS/WP.29/AC.3/44).

GRPE/2017/6 | Proposal for a new Supplement to the 06 series of amendments to Regulation No. 49 Proposal to introduce provisions to align UN R49 with recently introduced stage D EU legislation in order enable manufacturers to continue to utilize the provisions in paragraph 4 of Annex 9A to approve light commercial vehicles with a light duty OBD architecture under this regulation. This proposal incorporates all of the provisions of the latest amendment to EU legislation. As stage D is unrelated to OBD, the proposal is to make stage C and all subsequent stages equivalent to EOBD 6-2.

GRPE-74-09 | Proposal for amendments to document GRPE/2017/6 on a new Supplement to the 06 series of amendments to Regulation No. 49 Comprehensive amendment of document GRPE/2017/6 to align UN R49 with the latest amendments of EU Euro VI legislation (Reg. EU 2016/1718), including<ol class="alpha"><li>OBD equivalency option for light commercial vehicles to be continued with step ‘D’,</li><li>editorial corrections (incl. keeping optional THC PEMS measurement for gas engines),</li><li>implementation dates in Appendix 9 table 1 (2016/1718) and Annex 3 table 1 (R49),</li><li>implement rejection note for retroactive applicability with regard to in-service conformity (paragraph 13.4.),</li></li>clarification of type approval provisions for ‘new vehicle types as of 2017’,</li><li>deletion of infeasible requirement related to the PEMS test (“…void if … no valid windows left in urban only”), second part of sentence in Annex 8, Appendix 1: A1.4.2.2.2.2.</li><li>deletion of inconsistency between work based window and CO2 mass based method regarding valid integration windows (A.1.4.2.2.2.2. versus A.1.4.3.1.2.2).</li></ol>

GRPE-74-08 | Proposal for a new Supplement to the 05 and 06 series of amendments to Regulation No. 49 Proposal to correct and clarify the text, including to<ol class="alpha"><li>correct the constants for equation (34) to calculate exhaust mass flow using carbon balance method,</li><li>correct constants used for CVS verification,</li><li>correct the formula for regression analysis according to Annex 4, Appendix 3, and</li><li>correct the rise time (to 3.5 s from 2.5 s) for the PEM analyzers under paragraph A.2.2.1. of the 06 series.</li></ol>With regard to the 06 series, the proposal may be considered as an amendment to document GRPE/2017/6.

GRPE-74-14 | Update of Regulation No. 132 for EU Stage V In line with the need to update UN R96 in response to the new EU Stage V NRMM regulation, Regulation (EU) 2016/1628 would impact UN R132. Therefore, EUROMOT recommends updating UN R132 in parallel with UN R96 and UN R120. In particular, EUROMOT proposes establishing a specific annex to UN R132 in light of the similar stringencies of EURO VI heavy duty emissions requirements and those of NRMM Stage V that would specify all the necessary additional requirements for Stage V (in a manner similar to the existing Annex 12 for emission levels equivalent to the 06 series of amendments of UN R49).

GRPE-74-23 | Approval of replacement pollution devices within Regulation No. 49 Proposal to ensure that all replacement pollution control devices conform with the intent of UN R49 and to align UN R49 in this regard with Regulation (EU) 2016/1718. CLEPA proposes the establishment of a new annex under UN R49-05 R.49-05 to restrict the approval of a replacement device to one that “enables the engine and vehicle to comply with the rules with which it was originally in compliance”.

GRPE-74-09 | Proposal for amendments to document GRPE/2017/6 on a new Supplement to the 06 series of amendments to Regulation No. 49 Comprehensive amendment of document GRPE/2017/6 to align UN R49 with the latest amendments of EU Euro VI legislation (Reg. EU 2016/1718), including<ol class="alpha"><li>OBD equivalency option for light commercial vehicles to be continued with step ‘D’,</li><li>editorial corrections (incl. keeping optional THC PEMS measurement for gas engines),</li><li>implementation dates in Appendix 9 table 1 (2016/1718) and Annex 3 table 1 (R49),</li><li>implement rejection note for retroactive applicability with regard to in-service conformity (paragraph 13.4.),</li></li>clarification of type approval provisions for ‘new vehicle types as of 2017’,</li><li>deletion of infeasible requirement related to the PEMS test (“…void if … no valid windows left in urban only”), second part of sentence in Annex 8, Appendix 1: A1.4.2.2.2.2.</li><li>deletion of inconsistency between work based window and CO2 mass based method regarding valid integration windows (A.1.4.2.2.2.2. versus A.1.4.3.1.2.2).</li></ol>

GRPE-74-13 | Alignment of Regulation No. 96 to EU Stage V <a href="http://eur-lex.europa.eu/eli/reg/2016/1628/oj" target="blank" class="orange">Regulation (EU) 2016/1628</a>, also known as the NRMM Regulation or Stage V Regulation, restructures the EU regulation of non-road mobile machinery ranging from lawn mowers to snow mobiles to bulldozers, but excludes agricultural machinery (to be subjected to a separate EU regulation). In order to maintain the alignment between UN Regulations on emissions and EU emissions regulations, the EC proposes GRPE work on a new series of amendments to UN R96 (and by extension UN R120) for publication in 2018.

GRPE/2017/4 | Proposal for a Supplement to the draft Regulation on uniform provisions concerning the approval of Heavy Duty Dual-Fuel Engine Retrofit Systems (HDDF-ERS) to be installed on heavy duty diesel engines and vehicles During the June 2016 GRPE session, AEGPL raised concerns regarding the back-to-back approach for the simplified test of retrofitted dual-fuel engines because, in some cases, the hydrocarbons (HC) and/or carbon monoxide (CO) emission values of the original diesel engine are far below the emission limit (see GRPE-73 session report, para. 28). AEGPL proposed a solution in document GRPE-73-07. However the Netherlands is concerned that:<ol class="alpha"><li>The emission performance of the selected diesel engine is not known (above or below the emission limit and how far from the limit);</li><li>Non-methane hydrocarbons (NMHC) emission cannot be disregarded because NMHC is an important air quality regulated pollutant emission; and</li><li>The diesel emissions of CO and HC could be far below the emission limit and hence a factor of two would not be sufficient while increasing this factor is problematic.</li></ol> Contracting Parties and stakeholders have discussed a solution, presented in this proposal, to compare measured emissions of a retrofitted dual-fuel engine with the brake specific emission limits using a CO2 specific emissions approach. This proposal would amend the draft regulation pending before WP.29 (document WP.29/2016/110).

GRPE-74-25 | Proposal for amendments to ECE/TRANS/WP.29/GRPE/2017/4 on Heavy Duty Dual-Fuel Engine Retrofit Systems Proposal to restrict the application of CO2 specific emission limits only to NMHC and CO emissions (back-to-back comparison of NOx and PM to apply under the regulation in any case). The proposal also aligns the text where applicable with the intent of paragraph 2.3.15.: "R49 original emission limits" means the emission limits as defined in Regulation No. 49 to which the original engine system was approved."
