50. The expert from Japan introduced a proposal for corrigendum to UN GTR No. 2 (GRPE-64-05), to correct some equations in accordance with the units used, as well as a figure on the gear use during acceleration phases.

51. The experts from India and IMMA requested more time to analyze this document in detail.

52. Taking the new criteria for corrigenda into account, GRPE considered the proposal from Japan as an amendment rather than a corrigendum and requested the expert from Japan to ask for a mandate to amend UN GTR No. 2 from WP.29 and AC.3. GRPE also asked Japan to discuss with India and IMMA the concerns expressed and to submit an updated version of GRPE-64-05, so that the secretariat can distribute it as an official document for consideration at the next GRPE session, in January 2013, subject to the consent of WP.29 and AC.3 on a mandate to amend UN GTR No. 2.

53. The expert from the EC introduced documents GRPE-64-02 and GRPE-64-09. He explained the European process of revising type approval procedures for L-category vehicles, introduced a proposal containing the terms of reference for the establishment of an Informal Working Group on International L-category vehicle approval in the area of Environmental Performance and Propulsion Requirements (IEPPR), confirmed the invitation to GRPE participants to attend a stakeholder consultation workshop on the topic, and briefly outlined its content. He announced that the documents GRPE-64-10, GRPE-64-12 and GRPE-64-22 were to be introduced during the stakeholder consultation workshop.

54. The expert from Switzerland asked whether there would also be other working groups in other Working Parties subsidiary to WP.29. The expert from the EC clarified that the main focus is on environmental issues and that this is not foreseen at the moment, also stating that he would be open to such a development, if needed.

55. The expert from the EC introduced GRPE-64-11, containing draft Terms-of-Reference (ToR) for the IEPRR informal working group. The expert from the UK introduced GRPE-64-26, elaborating on the draft ToR of GRPE-64-11 with the aim to align them with the overall objectives of regulatory harmonization, technology neutrality and real-world representativeness in order to clarify the aims of the group. He explained that GRPE-64-26 also contains the addition of procedural issues such as project plans, document submission deadlines, meeting arrangements. He noted that the candidates as of Chair and Secretary should also be specified once they have been identified.

56. The expert from Japan supported the initiatives of the EC and the UK and expressed interest in the activity. The expert from IMMA thanked the EC and the UK for presenting the draft ToR and for considering items that help its effectiveness. He underlined the notion that the informal group should at least maintain, and ideally increase, current levels of harmonisation, he supported the idea of real world representativeness of the tests considered in this activity, and announced that IMMA is willing to discuss engagement in the informal group after a clarification of its scope and its ToR.

57. GRPE expressed the intention to agree, in principle, to ask for a mandate for the setup of an informal working group as soon as some remaining issues, such as the identification of an informal group Chair and Secretary, will be addressed. The GRPE Chair asked Japan, the UK, the EC, IMMA and other interested Parties to work on this, so that a formal request for a WP.29 mandate can be finalized at the next GRPE session, in January 2013. He also suggested that the work should be set up in a two-step approach, first focusing on the development of a roadmap and then concentrating on the development of the draft Regulation(s).

Proposal to align UN R96 with European Directive 97/68/EC as amended in 2012 and to align table of 8 mode cycle with 2010/26/EU.

45. The expert from the EC gave a presentation (GRPE-64-25) introducing GRPE-64-03, which contains a proposal to amend UN Regulation No. 96 so that its provisions are aligned with the 8 mode cycle of European Directive 2010/26/EU and the 2012 amendment of European Directive 97/68/EC.

46. GRPE agreed and requested the secretariat to distribute GRPE-64-03 as an official document for consideration at the next GRPE session in January 2013.

Letter from the Retrofit Emissions Control Devices (REC) informal group to solicit input regarding the proposed two-stage implementation of stringency levels in the new REC regulation under development.

29. The Chair of the informal group on REC mentioned that good progress is being achieved in drafting the UN Regulation and added that a draft UN Regulation is expected to be ready by the next GRPE session, in January 2013.

30. GRPE took note of the work progress and agreed that the group should meet in conjunction with its session in January 2013.

31. The REC Chair explained some issues that may emerge from the way the group intends to tackle the need for two levels of stringency in the UN Regulation (original version and, in parallel, a first series of amendments), illustrating the content of a letter addressed to GRPE participants (GRPE-64-04) asking for an indication of the level of stringency that they would be ready to accept. Having reported that he received an indication from some member States of the European Union to accept a higher stringency level (level 2), and having informed GRPE that the Russian Federation was the only Contracting Party that indicated its willingness to adopt lower stringency requirements (level 1), he invited other Contracting Parties to express their intentions. He also clarified that, if level 1 requirements are favoured by less than 20 per cent of the Contracting Parties, the group will have to use the level 2 requirements directly.

32. The expert from the Russian Federation confirmed the intention to apply level 1 of stringency. The expert from the UK warned that, since there is no European legislation on retrofit systems leading to the need to accept only level 2 stringency levels, the UK would see no issues with the support of the approach involving two levels of stringency by single member states of the European Union. The expert from the European Commission clarified that Germany and Italy indicated their willingness to accept level 2 stringency. In disagreement with the expert from the UK, he also stated that, should the European Union adopt the stringency level 2, then single member States would not be in a position to adopt a different level of stringency.

33. GRPE asked the experts from the EC and the UK to clarify the situation by the end of August 2012, and asked all Contracting Parties to indicate, also by the end of August 2012, their position on the level of stringency to the REC Chair.

Responding to a question from the expert from OICA, the GFV Chair clarified that the proposal assured the necessary accuracy needed for type approval. Similar proposals concerned UN Regulation No. 115 (para. 63.).

19. The expert from OICA introduced ECE/TRANS/WP.29/GRPE/2012/11/Rev.1, proposing to align UN Regulation No. 83 with the Regulation (EU) No. 566/2011. He explained that the initial transposition of the Euro 5 requirements could not take these amendments into account because they have been published later. He also underlined that clarity has been introduced to the definition of cold start, in response to the concerns raised by the expert from Poland at the sixty-third GRPE session.

20. The expert from the UK requested to revise the amendment proposed for paragraph 5.2.3., Table A so that the text “particulate number” is replaced by “particle number”.

21. The secretariat introduced GRPE-64-15, containing a proposal to delete the references made to Annex 4 in Supplements 1 and 2 to the 06 series of amendments (Revision 4) to UN Regulation No. 83, since they include changes to Annex 4, while Annex 4 is missing from the text of the Revision 4 of the UN Regulation.

GRPE expressed the intention to agree, in principle, to ask for a mandate for the setup of an informal working group as soon as some remaining issues, such as the identification of an informal group Chair and Secretary, will be addressed. The GRPE Chair asked Japan, the UK, the EC, IMMA and other interested Parties to work on this, so that a formal request for a WP.29 mandate can be finalized at the next GRPE session, in January 2013. He also suggested that the work should be set up in a two-step approach, first focusing on the development of a roadmap and then concentrating on the development of the draft Regulation(s).

Roadmap projecting submission of the draft global technical regulation to WP.29 in March 2014.

11. The Secretary of the WLTP informal working group introduced GRPE-64-27, containing an updated roadmap, illustrating its main modifications and confirming the need for a special GRPE session, in late 2013, for the final review and adoption of the draft UN GTR.

12. The Secretary of the WLTP informal working group also reported on the progress made by the sub-group on the Development of the Harmonized driving Cycle (DHC), introducing GRPE-63-28. He summarized the results of validation phase 1, he introduced briefly the profile of the version 5 of the World Light Duty Test Cycle (WLTC), and touched upon the work on the gear shift prescription. He mentioned that five out of nine open issues have been solved, explaining that further discussion is needed for cycle modifications and next actions, with a solution expected by the end of the year. He added that mode construction and gear shift points were the remaining items to address.

13. The WLTP Secretary reported about the proposal from Japan to introduce further modifications to version 5 of WLTC. The expert from the EC expressed some concerns on such modifications to the test cycle, underlining that the EC favours the version 5 of the WLTC, as agreed before. The experts from France and Italy underlined the importance of the representativeness of the test cycle with respect to pollutant emissions, CO2 emissions and fuel consumption, also underlining the need to take into account regional specificities and to the importance of the WLTC for accurate consumer information, since the WLTC is expected to be used for the characterization of energy efficiency labels.

14. The Chair of the sub-group on the Development of the Test Procedure (DTP) introduced GRPE-64-30, informing GRPE on the development of validation phase 2 by the Validation Task Force (VTF), on the activities of the Lab Process-Internal Combustion Engines (LabProcICE) subgroup, on the work of the Lab Process-Electric Vehicles (LabProcEV) sub-group, and the progress of the Additional Pollutants (AP) sub-group. Speaking about the UN GTR drafting work, he announced a draft UN GTR text should be submitted at the next GRPE session.

15. GRPE took note of the updated roadmap, acknowledging it does not result in a postponement of the WLTP finalization. The Working Party agreed that the special session the final adoption of the draft GTR should be held back to back with the WP.29 session of November 2013, subject to the confirmation from WP.29 and the secretariat. GRPE also agreed that the WLTP subgroups should meet in conjunction with its session in January 2013 (note by the secretariat: at its 157th session, WP.29 gave its consent to hold the special session of GRPE on Thursday afternoon, 14 November 2013).

(a) International Whole Vehicle Type Approval (IWVTA);
(b) Recyclability of M1 and N1 vehicles;
(c) Vehicle Propulsion System Definitions (VPSD).

3. The informal documents distributed during the session are listed in Annex I to the session report.

4. GRPE delegates were informed that the next session of GRPE will take place from 15 to 18 January 2013 and that the deadline for the submission of official working documents is 19 October 2012.

Revised submission by the Chair of the informal group on Gaseous Fuelled Vehicles (GFV) to redefine the class of bi-fuel vehicles to permit the simultaneous use of gas and petrol in gas mode in UN Regulation No. 83. This document replaces GRPE/2012/6.

18. The Chair of the informal group on Gaseous-Fuelled Vehicles (GFV) presented ECE/TRANS/WP.29/GRPE/2012/6/Rev.1, proposing to amend UN Regulation No. 83 regarding the simultaneous use of gas and petrol under certain conditions on some bi-fuel vehicles equipped with petrol direct injection systems. He also introduced GRPE-64-21 (updating GRPE-64-06), proposing to amend ECE/TRANS/WP.29/GRPE/2012/6/Rev.1 for issues concerning the G₂₀ and G₂₅ reference fuels. Responding to a question from the expert from OICA, the GFV Chair clarified that the proposal assured the necessary accuracy needed for type approval. Similar proposals concerned UN Regulation No. 115 (para. 63.).

19. The expert from OICA introduced ECE/TRANS/WP.29/GRPE/2012/11/Rev.1, proposing to align UN Regulation No. 83 with the Regulation (EU) No. 566/2011. He explained that the initial transposition of the Euro 5 requirements could not take these amendments into account because they have been published later. He also underlined that clarity has been introduced to the definition of cold start, in response to the concerns raised by the expert from Poland at the sixty-third GRPE session.

20. The expert from the UK requested to revise the amendment proposed for paragraph 5.2.3., Table A so that the text “particulate number” is replaced by “particle number”.

21. The secretariat introduced GRPE-64-15, containing a proposal to delete the references made to Annex 4 in Supplements 1 and 2 to the 06 series of amendments (Revision 4) to UN Regulation No. 83, since they include changes to Annex 4, while Annex 4 is missing from the text of the Revision 4 of the UN Regulation.

22. GRPE adopted ECE/TRANS/WP.29/GRPE/2012/6/Rev.1, as amended by GRPE-64-21, as well as ECE/TRANS/WP.29/GRPE/2012/11/Rev.1, incorporating the amendments proposed in GRPE-64-15 and correcting it as indicated below:
Paragraph 5.2.3., Table A, replace “particulate number” by “particle number”.
GRPE requested the secretariat to submit these two proposals to WP.29 and AC.1 for consideration at their November 2012 sessions, as Supplement 3 to the 06 series of amendments to the UN Regulation No. 83.

Mr. Rijnders notes that in the UNECE website document 2012/7 was listed as pertaining to R.83. In fact this pertains to R.115. Mr. Seisler will contact Pierpaolo Cazzola (GRPE secretariat) to make the necessary change.

Mr. Harry Scheule (Continental) Amendment presents the CLEPA document Regulation R83 and document GRPE Working Document GRPE/2012/6 regarding the use of petrol in gas mode and its limitation for bi-fuel gas vehicles and the verification during type approval.

In Appendix 1 and 2 of GRPE/2012/6, it is proposed to determine the amount of consumed fuel during the type 1 test by measuring the weight of an additional external fuel tank for the gaseous fuel (NG or LPG or H2). From the CLEPA point of view this procedure might entail practical and safety problems during development and type approval. For that reason CLEPA proposes an alternative procedure in order to determine the fuel consumption of petrol and the gaseous fuel in the test cycle as an equivalent option as a new Appendix 3.

Alternative proposal by CLEPA

• - Based on the injection time and flow rate through the fuel injectors
• - Values should be available in the ECU or in the additional gas control unit (GCU).
• - Implement a new Parameter ID for generic SCAN tool (J1979/ISO 15031-5)

Comparison of fuel consumption has been made for engine management systems and the exhaust of the system.

What needs to be done by the car industry?

• - A new PID has to be requested at J1979- community. (All vehicles according to R.83 have to support ISO 15031-5 = J1979.)
• - The new PID has to be implemented into the engine management or in the controller of the secondary fuel system.

Advantage of the proposed method is:

• - Weighing of an external and separate CNG tank is not required
• - No risk of gas leakage or contamination
• - Mpetrol could be easily verified by comparison with the Fuel Consumption calculated based on the bag analysis.
• - Mpetrtol and Mgas could be verified by calculation of resulting CO2 emission of Mpetrol and Mgas and comparison with the C02-Emission based on the bag analysis.
• - Mpetrol and Mgas could be verified by comparison with the injection pulses; if the pulses on both kinds of injections, Mpetrol and Mgas must increase.

AEGPL would support this change. But they would prefer an official test based on official data.

The discussion surrounds whether this method can be used for type approval because the data is provided by the manufacturer it is not necessarily good enough to use for type approval. Mr. Rijnders makes a point that a lot of this data may not give a good picture of the amount of energy consumed. It also is a complicated procedure to adopt. Mr. Dekker (TNO) indicates that the data from the manufacturer would have to be ‘trusted.’ For manufacturers the method is fine but not necessarily from a regulatory view. But it is agreed that the suggested method is an ‘elegant’ alternative to weighing the gas in an external cylinder. But Mr. Rijnders has some doubts about bringing this recommendation to the GRPE at this stage of its development.

There is a way of cross checking the petrol and gas values and adding them together: Portion of injection gasoline mass to portion of injection natural gas mass. The only requirement is to prove that the amount of injected petrol has to be lower than 20%.

This method would have to be justified as a good alternative at the GRPE. Mr. Scheule can work to improve the test, and that we would work in the GFV group for alternatives to this methodology (different than weighing-the-tank methodology). While there are concerns about safety these should not be the principle reasons for changing the test procedure. There is general agreement that this method is an ‘elegant’ solution and is an improvement over the weighing methodology and that it has merit. But some few questions still need to be answered and CLEPA will work to revise the method and satisfy questions at an upcoming GFV, but not necessarily in the short-term for the June GFV session. CLEPA will try to demonstrate that the method be made more robust from a type approval perspective. Mr. Schuele agrees that it is good to have the feedback from this group in order to refine the methodology. The proposal is much more likely to have success at the GRPE once a consensus is achieved at the GFV.

View on GRPE formal documents for R83 and R115 (highlight discussion at GFV-20 and anticipated at GRPE-64). With respect to informal documents on which the two formal ones are based, in line with comments received in GRPE-63rd and as agreed by the group in GFV-18th, only that concerning R 115 has been subject to a significant modification: new requirements for petrol use in the gas mode have been restricted to direct injection petrol engines.

GFV-21-02 aims at introducing a mass correction factor for CNG reference fuel G25 in both documents ECE/TRANS/WP.29/GRPE/2012/6 and /7. A minor correction for the formulae used in both documents and for both gaseous fuels is highlighted: the proposed requirements make reference to gas ratios in percentage while the formulae generate decimal numbers. Attendees agree to correct the formulae making them consistent with the related requirements. Mr. Piccolo commits to drafting a proposal to be circulated to the group for final approval before tomorrow.

16. Mr. Rijnders informed the group that the changes to Regulation 83 and Regulation 115 were approved by the GRPE. The Technical Committee for Motor Vehicles (TCMV) in Brussels will vote on this regulation next week to mandate the Commission to vote positively in WP.29 in November 2012.

17. The new proposal tabled by CLEPA (GFV-22-02) represents an updated version of the document GFV-20-03 that was presented by Harry Scheule (Continental/CLEPA) and discussed at the last GFV in Bologna, 14-15 May 2012. Winfried Langer (CLEPA/Bosch) introduced the new document: since the weighing-of-gas-tank procedure, which the current amendments are based on, may, from CLEPA’s viewpoint, raise practical and safety problems during development and type approval. An alternative method is proposed for the identification of gas fuel mass as calculated by the ECU, making use of the injection time and flow rate through the fuel injectors,

18. Ms. Leifheit (ACEA/VW) said that she has not had a chance to check this alternative approach with her colleagues. She would have preferred to see the document earlier, therefore, they cannot make any comments but it looks very promising.

19. Mr. Del Alamo (NGVAE) also indicates that the document looks very good but that some more time is needed to review the proposal.

20. Mr. Piccolo (AEGPL) agrees that, even if based on proprietary data, the use of ECU outputs is undoubtedly more ‘elegant’ than the weighing procedure, and, if accepted by the authorities, it would be a valuable alternative to gas tank weighing, that could still be the method in the event of a dispute.

21. Mr. Dekker sees some potential problems regarding 2% accuracy measuring CO2. The 2% error in CO2 can mean a 10% error in petrol consumption in percentage. The proposed validation procedure of ECU data needs further investigation and, furthermore, a detailed legal text about this process must be included in the regulation. The advantage of the weighing method is that it can be checked. So, additional work has to be done to get a consistent proposal.

22. As regards the errors, Mr. Langer points out that 2% error in the petrol mass would imply a 2% error in the CO2 by calculation.

23. Mr. Rijnders understands that the work of the OEM can be accurate, but from the regulator’s view as a type approval procedure they have to be able to check.

24. Mr. Rijnders indicates that we must wait for OICA/ACEA’s response. He suggests that by December the GFV members should make comments in a written paper so the issue can be discussed again in January 2013. He asks CLEPA to prepare in detail, in the next two-three weeks, two informal documents (both R. 83 and R. 115) for the GRPE January 2013 session, possibly taking into account the comments expressed today. These informal documents will be sent to the GFV members before the end of October for consideration. Deadline for comments from GFV members must be provided by the end of November/early December Thereafter CLEPA will try to revise their proposals in accordance with the collected comments. If needed, a possible telephone conference can be arranged in December among GFV members in advance of the January 2013 GFV. Otherwise, the final drafts will be dealt with directly in the January 2013 GFV.

Revised submission by the Chair of the informal group on Gaseous Fuelled Vehicles (GFV) to redefine the class of bi-fuel vehicles to permit the simultaneous use of gas and petrol in gas mode in UN Regulation No. 115. This document succeeds Informal document GRPE-63-06-Rev.1 and replaces GRPE/2012/7.

63. The Chair of the informal group on Gaseous-Fuelled Vehicles (GFV) presented ECE/TRANS/WP.29/GRPE/2012/7/Rev.1, proposing to amend UN Regulation No. 115, regarding the simultaneous use of gas and petrol in gas mode under certain conditions on some bi-fuel vehicles equipped with petrol direct injection systems. He also introduced GRPE-64-21 (updating GRPE-64-06), concerning the use of G20 and G25 reference fuels and proposing to amend ECE/TRANS/WP.29/GRPE/2012/7/Rev.1. Similar proposals concerned UN Regulation No. 83 (para. 18).

64. GRPE adopted ECE/TRANS/WP.29/GRPE/2012/7/Rev.1, as amended by GRPE-64-21, and requested the secretariat to submit a consolidated text to WP.29 and AC.1 for consideration at their November 2012 sessions, as Supplement 5 to the UN Regulation No. 115.

Mr. Rijnders notes that in the UNECE website document 2012/7 was listed as pertaining to R.83. In fact this pertains to R.115. Mr. Seisler will contact Pierpaolo Cazzola (GRPE secretariat) to make the necessary change.

44. GRPE adopted ECE/TRANS/WP.29/GRPE/2012/9/Rev.1, as amended below:

Paragraph 11.19., point (a), amend to read:
“… divided by the average minimum track width for each axle exceeds 0.90, the maximum design speed is restricted to 30 km/h;”
Paragraph 11.19., point (b), amend to read:
“… divided by the average minimum track width of all of the axles exceeds 0.90, the maximum design speed shall not exceed 30 km/h.”

GRPE requested the secretariat to submit it to WP.29 and AC.1 for consideration at their November 2012 sessions, as Supplement 1 to the 03 series of amendments to UN Regulation No. 96.
