10. The expert from OICA also presented GRPE-76-22 introducing GRPE-76-03 and GRPE-76-04, proposing to clarify the rules related to the selection of driving modes for testing of Off-Vehicle-Charging Hybrid Electric Vehicles (OVC-HEV). The Netherlands had some comments on the proposals GRPE-76-03 and GRPE-76-04 since the new text opens the door for interpretation plus the absence of any type approval authority confirmation. The Chair asked the cooperation of OICA and the Netherlands to work on an improved text. GRPE supported the intention of the proposal.

11. The expert from EC presented GRPE-76-32 proposing to amend the definitions for bi-fuel vehicles and align these definitions with those in UN Global Technical Regulation (UN GTR) No. 15. GRPE supported the intention of the proposal.

Go to session report

12. GRPE agreed to reconsider at the June 2018 session GRPE-76-03, GRPE-76-04 and GRPE-76-32. GRPE requested the experts from OICA and EC to combine the documents in one formal document.

Go to session report

13. GRPE reviewed the letter sent by the expert from Malta (GRPE-76-17). GRPE noted the statements of some delegations informing GRPE that they faced similar requests in the past and reporting that no evidence was provided that could convince of the environmental benefits of such retrofitted systems. GRPE noted also the need to verify the safety performance of such systems as the risk caused by the presence of hydrogen onboard of road vehicle is not insignificant. Experts from the automotive industry stated that they had reviewed the performance of such systems and that, due to the regulatory pressure on the industry concerning the CO2 performance of their products, they would have introduced such technologies on their vehicles, if the benefits would have been demonstrated. They also noted that hydrogen cause damage to the materials used in engines and that the retrofitting such systems on existing vehicles not foreseen for the use on hydrogen could pose durability issues. GRPE requested the secretariat to note in the session report that GRPE has not received sufficient evidences of benefits from these systems to start regulatory activities. GRPE expressed the idea that any country willing to approve such system on the national basis may wish to take into consideration the usual emission tests (Types I, II, III, and IV), low temperature tests, the durability (including Type V) and OBD provisions.

Previous Discussion(s)

Working Party on Pollution and Energy | Session 74 | 10-13 Jan 2017

14. The Vice-Chair of the IWG on WLTP reported on the progress made by the group on each of the tasks of the Phase 2 activities (GRPE-74-11).

15. The drafting coordinator of the IWG on WLTP presented ECE/TRANS/WP.29/GRPE/2017/7 on amendments to UN global technical regulation (GTR) No. 15 on WLTP. He also presented GRPE-74-02-Rev.1 introducing some changes to ECE/TRANS/WP.29/GRPE/2017/7 and he referred to GRPE-74-03-Rev.1 as a consolidated version of both documents. He introduced the technical report on the further development of WLTP (GRPE-74-05). He clarified that the technical report was a consolidated version combining all phases of the development of GTR No. 15 up to now.

16. GRPE adopted ECE/TRANS/WP.29/GRPE/2017/7 as amended by Annex V to this report and requested the secretariat to submit it to WP.29 and the Executive Committee of the 1998 Agreement (AC.3) for consideration and vote at their June 2017 sessions as draft Amendment 2 to GTR No. 15 on WLTP. GRPE also adopted the technical report (GRPE-74-05) as reproduced in Addendum 1 to this report and requested the secretariat to submit it to WP.29 and AC.3 for consideration and vote at their June 2017 sessions.

17. The expert from EC presented ECE/TRANS/WP.29/GRPE/2017/3 on a draft new GTR on evaporative emission test procedure for WLTP (WLTP EVAP). He clarified that the current proposal focuses on the evaporative emissions that can occur during parking events, so running losses and refuelling emissions are out of the scope for the time being. He explained that the test procedure for sealed fuel tank systems will be introduced at a later stage. He introduced the technical report on the development of the draft new GTR (GRPE-74-04).

18. The expert from ETRMA presented GRPE-74-10 to highlight that emissions from tyres should be excluded from the test procedure in the draft new GTR on WLTP EVAP. He explained that tyres should be removed at the stage of vehicle preparation, since they are not part of the fuel storing system and they may add some uncertainty to the test.

19. GRPE adopted ECE/TRANS/WP.29/GRPE/2017/3 and requested the secretariat to submit it to WP.29 and AC.3 for consideration and vote at their June 2017 sessions as a new draft GTR on evaporative emission test procedure for WLTP (WLTP EVAP). GRPE also adopted the technical report (GRPE-74-04) as reproduced in Addendum 2 to this report and requested the secretariat to submit it to WP.29 and AC.3 for consideration and vote at their June 2017 sessions.

20. The expert from EC presented a status report on the WLTP Task Force dealing with the transposition of WLTP into the 1958 Agreement (GRPE-74-20). He informed that the Task Force had not met yet, but the first meeting would take place in February 2017. For the [adaptation] of the 1958 Agreement to include WLTP, he explained the intention was to follow a two-step approach: first, introduction of transitional provisions in Regulations Nos. 83 and 101 (see paras. 11-13 above); second, full transposition of GTR No. 15 into new Regulations under the 1958 Agreement. He recalled previous presentations by EC and the Secretariat on possible ways to structure these new Regulations (GRPE-72-18 and GRPE-73-26).

21. GRPE agreed to further discuss the transposition of WLTP into the 1958 Agreement at the next GRPE session on the basis of the work carried out by the WLTP Task Force dealing with this topic.

22. GRPE acknowledged the progress made by the IWG on WLTP and noted the request for a meeting room for one day during the GRPE week in June 2017.

7. The expert from the Russian Federation presented ECE/TRANS/WP.29/GRPE/2017/2 on amendments to the scope of Regulation No. 83. He explained that the proposal was aimed at allowing extensions of type approvals granted under Regulation No. 83 to special purpose vehicles.

8. The experts from CLEPA and OICA expressed some concerns on the limitation of 2,610 kg reference mass introduced by the definition of special purpose vehicle in ECE/TRANS/WP.29/GRPE/2017/2. The expert from Hungary suggested the use of existing definitions in the Consolidated Resolution on the Construction of Vehicles (R.E.3). Following the discussion, the experts from Hungary and the Russian Federation presented GRPE-74-22 to amend ECE/TRANS/WP.29/GRPE/2017/2 by deleting the definitions of special purpose vehicle and armoured vehicle and referring to R.E.3 instead.

9. GRPE adopted ECE/TRANS/WP.29/GRPE/2017/2 amended by GRPE-74-22 as reproduced in Annex IV and requested the secretariat to submit it to WP.29 and the Administrative Committee of the 1958 Agreement (AC.1) for consideration and vote at their June 2017 sessions as draft Supplement 10 to the 06 series of amendments and draft Supplement 6 to the 07 series of amendments to Regulation No. 83.

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.

11. The Secretary of GRPE presented ECE/TRANS/WP.29/2017/42, ECE/TRANS/WP.29/2017/43 and ECE/TRANS/WP.29/2017/44 on transitional provisions to be introduced in Regulations Nos. 83 and 101 as an interim solution while the Worldwide harmonized Light vehicles Test Procedure (WLTP) is transposed into the 1958 Agreement. He explained that these documents were prepared by the Secretariat as agreed by WP.29 at its June 2016 session. Following the request of WP.29 and taking into account the urgency of the topic, he explained that the three proposals were already submitted to WP.29 and AC.1 for consideration and vote at their March 2017 sessions, but subject to the endorsement of GRPE at this session.

12. The expert from OICA presented GRPE-74-16 on some modifications to the wording of ECE/TRANS/WP.29/2017/42, ECE/TRANS/WP.29/2017/43 and ECE/TRANS/WP.29/2017/44. The expert from EC stated that he was not in the position to accept the changes introduced by GRPE-74-16.

13. Following the discussion, GRPE endorsed ECE/TRANS/WP.29/2017/42, ECE/TRANS/WP.29/2017/43 and ECE/TRANS/WP.29/2017/44 to be further considered by WP.29 and AC.1 at their March 2017 sessions.
