The minutes were adopted without any comment.

EPPR-13-24 | Draft minutes of the 13th EPPR informal group session

EPPR-14-08 | Draft minutes of the EPPR audio-web conference on 9 December 2015

Mr Zardini/EC JRC provided an update on the Euro 5 Study

• After a Pre-Study (so-called Phase 0, completed) which was an input for the “real” Euro 5 Effect Study and after Phase 1 (Public Survey and Market statistics, completed) of the Euro 5 Effect Study, now the Effect Study is in its Phase 2 (Experimental work), the core of the Effect Study.
• The contractor who is carrying out Phase 2 is TNO+LAT+EMISIA, mainly hosted at JRC.
• Phase 0 and Phase 1 were instead carried out by JRC alone.
• Phase 0 report to be available next month, slide 5.
• Document EPPR-14-18 is part of phase 1 of the study; was not discussed in detail during the meeting as it is European oriented, but some hints/advice can be found useful for extra-EU Parties.
• PN:
  • Same methodology as the one used for passenger cars, as starting point. Not decided if this method will be used for L-cat, but taken as initial as reference. At the moment there is no discussion or plan to introduce any PN measurement for L-cat type approval. It’s an exploratory investigation.
  • JRC expected L-cat to be dirtier than passenger cars due to their simple after treatment technology and absence of particle filters but had not expected this to make such a difference: For mopeds, PN level is 3-20 times the PN limit set for passenger cars; for motorcycles, it is 2-4 times higher.
• The group exchanged comments.
• IMMA thanked JRC for the update on the study and asked for some clarification on the selection of vehicles used in the tests, and noted the importance to compare recent motorcycle models (Euro 4) when comparing the performance with the latest cars (Euro 6). Mr Zardini replied that their tests were with Euro 2 mopeds, and mainly with Euro 3 motorcycles as there were relatively few Euro 4 vehicles made available today.
• Mr Narusawa-san/Japan asked to clarify whether it was correct to say that 2-strokes was main reason for this high levels for mopeds.
• JRC clarified that not, all of them display high levels of PN. The quality of 2-strokers’ PN is anyway different than the one of 4-strokers (soft organic material condensed on the particles), which may lead to more artefacts (re-condensation).
• JRC reminded that 2-strokers emit high level of PN, because of the presence of the oil in fuel and because of the easy re-condensation of material inside the measurement system after the heating treatment. A lot of particles below 23 nm and also below 10 nm had been noted. Probably JRC will need some modification for the different categories which are going to be tested.
• Chair asked whether PN should be kept on the agenda of the group. Since there was no comment, the issue was left on the agenda for next meeting.

GRPE-2016-02: No discussion necessary.

EPPR-14-12: Secretary recalled the importance of confirming such document, especially on the controversial open point about 3-wheelers. He suggested taking EPPR-14-15 by IMMA as a basis for review, since it was an improved version of 14-12, with editorial comments highlighted in track changes.

EPPR-14-15 was reviewed in details.

• Item 2 on 3W vehicles: Japanese (EPPR-14-10) and Indian (EPPR-14-13) comments were reviewed. As proposed by Japan and supported by India and EC, it was agreed to delete complete sub-para. (c) of GRPE-2016-02, para. 19 in Section 1.
• Item 3 was changed as follows:
  • 24 bis was renamed 25 and all sub-sequent paragraphs were re-numbered.
  • same similar family criteria
  • IMMA editorial improvement was accepted by India, by EC, by Japan.
  • India proposal (highlighted in blue font) was accepted.
  • Item 4 – 14: proposals agreed.

  EPPR-14-16 (IMMA), containing following additional editorial corrections to ensure consistency throughout the document, was agreed upon:

  • 1 Change fuel storage and supply system into fuel storage and delivery system.
    • Justification: To make the wording consistent throughout the gtr.
  • 2 Change Fuel storage tank into Fuel tank
    • Justification: To make the wording consistent throughout the gtr; In line with equal proposals made earlier by China and adopted by other EPPR members.

  Conclusion
  EPPR-14-15 and EPPR-14-16 were adopted; will be consolidated in a new informal document amending GRPE-2016-02 and submitted to January 2016 GRPE.
  GRPE-72-06, Technical Report, was agreed upon.
  Secretary explained that compared to previous final draft document (EPPR-14-09e):

  • The ‘authorisation’ was deleted, since the GRPE Secretariat had pointed out that it was not necessary to add the authorisation in the informal document. The ‘authorisation’ will be added by the UNECE Secretariat once the GTR and Tech. Report are adopted.
  • Some adjustments on the paragraph numbering had been made.

GRPE/2016/2 | Proposal for a new global technical regulation on the measurement procedure for two- or three-wheeled motor vehicles equipped with a combustion engine with regard to the crankcase and evaporative emissions Proposal for a new GTR on motorcycle crankcase and evaporative emissions prepared by the Informal Working Group on Environmental and Propulsion Performance Requirements (EPPR). This draft contains text in square brackets requiring decision-making by the GRPE.

Background
EPPR-13-23, Excel table, containing the development of the draft OBD GTR, up to the November meeting included.

Afterwards, the EC prepared a new proposal (EPPR-14-06), which differs from the previous one both in terms of contents and layout. It was published on 08.12.2016 but not discussed during the EPPR telco of December, since such meeting focussed on EVAP only. It was taken as new version of draft OBD GTR: version No.5

Japan inserted their comments on EPPR-14-06.

Discussion
Chair introduced the 3 latest documents available (EPPR-13-23, EPPR-14-06 and 14-14) and suggested to have EPPR-14-14 introduced by JPN.

EPPR-14-06 was presented by Japan.

EC thanked Japan and asked to add the definition of default mode in their proposal. Japan agreed to provide such definition at the next meeting.

Mr Nakhawa/India requested for a study reservation, especially on issues like repair information, assessment of OBD, items relating to intellectual property which are going to be submitted to authorities.

As requested by the Chair, stakeholders were invited to send written comments by Friday 05.02.2016, in good time for a fruitful discussion at the next telephone conference early February.

India asked for a clarification on pag.28 and deemed that there was no justification for the proposal on Grade A.

EPPR-13-23 | Draft GTR on motorcycle emissions OBD requirements (from 26-27 November discussions)

EPPR-14-06 | European Commission draft of the motorcycle OBD GTR Updated version of the draft GTR on motorcycle emissions OBD prepared for the EPPR informal group by the European Commission.

EPPR-14-14 | Japan comments on the latest EC draft of the motorcycle OBD GTR Proposed edits and refinements to the text of the draft motorcycle OBD GTR.

The Chair noted that the first priority is finalising GTR on OBD, before going-on tackling all other EPPR areas. Activities will continue in Phase 2 starting with the review of GTR2.

IMMA proposed a methodology of work for GTR2. Since GTR2 adoption a number of amendments have followed which have not been consolidated in a published document by UNECE. . EC had submitted to EPPR a proposal for GTR 2 revision [EPPR-11-15 Rev1].

IMMA proposed to use Excel within the group as a tool to keep track of the review and further development of the GTR2. This approach would enable to make correct reference to the paragraphs at stake. Upon finalisation of the activities on ODB, IMMA volunteered to prepare a comparison in Excel, containing two columns, one with the latest status of GTR2 Consolidated with the latest amendments and supplements and one with the EC proposal. The differences between the two versions would become apparent. . It would be appreciated if EC could then justify the main changes of EPPR-11-15 Rev1 and if every stakeholder could provide their further comments in new columns.

The above proposed methodology of work was approved by the group.

Chair showed EPPR-14-20, Roadmap and Project Planning, which would become also the basis for the report of the upcoming GRPE-72 session.

EPPR-14-19, draft “EPPR Meeting Schedule 2016”, was introduced by the Chair and reviewed by the stakeholders.

• Chair explained intention to submit an Official Document for GRPE, deadline is 14th of March
• Thus the face-to-face meeting was anticipated from April to March 3-4.
• Since 04.05.2016 is National holiday in Japan, it was proposed 25 or 26 April, and 12.04.2016 deleted.
• India asked to avoid collision with WLTP at the next meeting in conjunction with GRPE
