3. (a) Light vehicles: Regulations Nos. 68, 83, 101, and 103

7. The expert from OICA introduced ECE/TRANS/WP.29/GRPE/2018/13 clarifying the basis of the petrol tank capacity restriction for mono fuel gas vehicles. GRPE adopted the proposal.

GRPE/2018/13 | UN R83: Proposal for a new Supplement to the 06 and 07 series of amendments Proposal to clarify the fuel tank capacity restriction for mono-fuel gas vehicles. The definition of “mono-fuel gas vehicle” was slightly amended between the 06 and the 07 series of amendments to UN R83. This proposal aims to align the definitions across both series in order to avoid divergent interpretations. Although the reference to a 15 liters tank has always been understood to refer to the nominal capacity of the tank, the use of the term “nominal capacity” in UN GTR No. 19 in several places other than the definition of “mono-fuel gas vehicle” can lead to other interpretations of the definition. The word “nominal” should therefore be inserted into the definition in both series of amendments.

8. The expert from OICA introduced ECE/TRANS/WP.29/GRPE/2018/14 and ECE/TRANS/WP.29/GRPE/2018/16 aimed at clarifying provisions on mode selection when measuring emissions from OVC-HEV and bi-fuel gas vehicles. The expert from the Netherlands proposed amendments (GRPE-77-02 and GRPE-77-03) to ECE/TRANS/WP.29/GRPE/2018/14 and ECE/TRANS/WP.29/GRPE/2018/16 respectively. The experts from France and Sweden supported the proposals from the expert from The Netherlands. GRPE adopted the proposals as reproduced in Annexes IV and V respectively.

GRPE-77-22 | WLTP informal group status report

16. The expert from EC, leading the task force on the transposition of WLTP into the 1958 Agreement, presented GRPE-77-21 on the activities of his group.

17. He introduced the implications that the forthcoming UN Regulation on WLTP would have on UN Regulations No. 83 and No. 101. Four options are now under consideration to assist Contracting Parties (CPs) once the UN Regulation on WLTP has been created. He stated that further analysis would be undertaken in the coming months. The secretariat mentioned some practices from GRE on the procedure to freeze unused UN Regulations, that could be explored to properly manage UN Regulations Nos. 83, 101 and on WLTP.

18. He reported on the progress done on durability and Conformity of Production (CoP) provisions, where three approaches are considered. The provision on durability and CoP could either be developed as new UN GTRs, as annexes to UN GTR No. 15 or directly into the forthcoming UN Regulation on WLTP. The expert from EC expressed her preference to have them included directly into the forthcoming UN Regulation on WLTP. India reminded GRPE that such issue had already been raised previously (ECE/TRANS/WP.29/GRPE/75, para. 8.), when India expressed its preference for separate UN GTRs. India also mentioned the possibility to have that as part of a Mutual Resolution. The chair of IWG on WLTP stated that a UN GTR for CoP would only include technical requirements, not administrative ones. GRPE agreed to develop durability and CoP as annexes to UN GTR No. 15.

19. GRPE discussed the possible alternatives to structure the future UN Regulation on WLTP to address regional specificities. Following the consultation of the Office of Legal Affairs (OLA) by the secretariat, GRPE agreed to tentatively adopt approach 2 as noted in GRPE-77-21.

GRPE-77-21 | WLTP transposition into UN Regulations update

20. GRPE endorsed ECE/TRANS/WP.29/2018/73/Add.1 submitted for formal adoption at the June 2018 session of the Executive Committee of the 1998 Agreement (AC.3).

21. GRPE acknowledged the progress made by the IWG on WLTP and noted the request for a meeting room for one and a half days during the GRPE week in January 2019.

3. (c) Light vehicles: Worldwide harmonized Real Driving Emissions test procedure

22. The expert from the European Commission advocated for a UN GTR on Real Driving Emissions (RDE) (GRPE-77-30). She briefly introduced draft Terms of References (ToR) that would guide the work of the forthcoming IWG on RDE (GRPE-77-15).

23. The expert from the United States of America showed interest and tentatively supported this nascent activity. He expressed the need to gain expertise, he showed understanding to the EC position but highlighted the need to accommodate regional specificities. He recognized the timeline detailed in the draft ToR to be very ambitious and requested time to study the draft ToRs presented for the first time at this session.

24. The expert of Canada also declared an interest in the work on RDE. He highlighted potential difficulties that the group could face trying to determine a globally harmonized stringency level for RDE.

25. The expert from India also supported this work and vowed to determine a list of parameters to be harmonized. He also stated that the timeline should allow enough flexibility for all CPs to contribute.

26. The expert from China informed that China includes RDE in the latest China 6 standard since the end of 2016. He stated China performed continuous improvements to the RDE regulatory texts and would therefore be interested to participate in the activities of the IWG on RDE.

27. The expert of EC heard the concerns about the timeline that could be adapted at the first meeting of the IWG on RDE. She invited all interested parties that would be interested to participate to the IWG on RDE, subject to AC.3 consent, to send an email to EC-RDE@ec.europa.eu.

28. GRPE supported the idea of activities on RDE and the draft ToRs.

29. The expert from OICA informed on the support to this work and would identify the best candidate to act as secretary to the IWG on RDE. He also expressed concerns about the ambitious timeline (GRPE-77-27).

30. The experts from Japan and the Republic of Korea reiterated their support and interest to be Vice-Chairs to the activity.

31. The Chair of GRPE stated that RDE activities were an important step towards more consistent approaches to ensure low levels of tailpipe emissions under a wide range of operating conditions and congratulated the large number of CPs that showed interest in the topic.

GRPE/2018/19 | UN R24: Proposal for amendments Proposal to align UN R24 (Compression Ignition Engines – Emission of Visible Pollutants – Power Measurement) with UN R85 with regard to correction factors.

39. The expert from Italy introduced GRPE-77-09 on the need to update UN Regulation No. 115 and the need to introduce a reference to WLTP instead of emission tests performed on the basis of the former test cycle (New European Driving Cycle (NEDC)). He proposed to host a meeting with all interested parties in order to develop a working document that would be presented at the January 2019 session of GRPE. He mentioned the letter from the expert of AEGPL showed support to the idea and interest to participate in the activities (GRPE-77-23). He stated that the difficulty for this work was that WLTC was not yet included in a UN Regulation but in a UN GTR.

GRPE-77-09 | UN R115: Proposal for amendments This document addresses the need to align Regulation No.115 to the new WLTC test cycle, defined in the GTR 15 and in the Commission Regulation (EU) 2017/1151 and later modifications.

40. The expert from OICA presented GRPE-77-06 proposing a new Supplement to UN Regulation No. 85 (Measurement of the net power) amending provisions on power measurement of air-cooled high-power engines. The expert from the Netherlands needed more clarifications on the actual proposal. The expert from OICA stated all questions would be answered before the next session of GRPE in January 2019.

GRPE-77-06 | UN R85: Amendment proposal Proposal to introduce an alternative test method for measuring charge-air-cooled engines net power for use with high power engines of those. The proposal would “decrease the charge air cooler outlet temperature by the same amount that the ambient conditions for the vehicle test varied from the standard temperature” in line with SAE J1349, “9.3 Application of Vehicle Transient Data to Net Power Test.”

7. Particle Measurement Programme (PMP)

43. The Secretary of the IWG on Particle Measurement Programme (PMP), on behalf of the Chair of the IWG on PMP, presented a status report on the activities of the group on exhaust and non-exhaust particle emissions (GRPE-77-14). She reported on the ongoing activities for exhaust and non-exhaust works streams.

44. She requested guidance from GRPE on exhaust emissions in the new activities on the impact of fuel quality on PN emissions and especially on the scope of the literature review: which emissions (engine out or tailpipe), what vehicle types (light-duty, powered 2-wheelers and/or heavy duty) and what engine type (positive ignition or compression ignition) should be considered in the research. The expert from EC expressed a preference for tailpipe emissions for all vehicle and engine types. GRPE agreed with the preference from the expert of EC.

45. The expert from Japan requested more information on non-exhaust emissions and how the braking schedule had been developed. The expert from OICA detailed that WLTP data had been used to develop a specific, new test cycle for brake tests. GRPE showed interest to validate the newly developed cycle and compare it with real driving conditions.

46. GRPE acknowledged the progress made by the IWG on PMP and noted that the group requested a meeting room for half a day during the GRPE week in January 2019.

9. Electric Vehicles and the Environment (EVE)

51. The Chair of the IWG on Electric Vehicles and the Environment (EVE) presented a status report on the ongoing activities of the group (GRPE-77-28) under the three areas of work. First, he explained the ongoing work on GTR development for the test procedure to determine power of electrified vehicles He requested input from GRPE on whether this work should be done as an annex to the UN GTR No. 15, as a standalone UN GTR or as a new part to UN Regulation No. 85. The experts from Sweden, UK and EC supported to have a standalone UN GTR, with the expert from the Netherlands further added that such standalone UN GTR could be then serve as a basis for an amendment to UN Regulation No. 85. The expert of Japan stated their preference to keep the existing mandate to have power system determination as an annex to UN GTR No. 15. The expert from OICA introduced GRPE-77-07 highlighting the strong connection between system power determination and UN GTR No. 15. The Chair of the IWG on WLTP informed GRPE that all options would be manageable without a need for substantially more resources. GRPE decided to consult AC.3 and the best way forward.

52. Second, he reported on the continuous research on battery durability and referred to activities from the Joint Research Centre (JRC) on a battery life parameterized simulation model validated by on-road testing (led by Canada). He highlighted that the final recommendations, likely to be prepared until 2019, would include a recommendation to seek authorization for relevant additional activities such as UN GTR development or may recommend concluding the topic. The expert from EC supported the development of a UN GTR on durability as this is a priority for EU legislation and as it is not covered by European legislation for the moment.

53.
