Text prepared by CLEPA to introduce a prohibition on any flow of a gaseous fuel into a diesel/gasoline reservoir and limiting the flow of diesel/gasoline into a gaseous fuel tank in bi-fuel vehicles.
20. The Chair recalled the purpose of ECE/TRANS/WP.29/GRSG/2012/17 (tabled by AEGPL) clarifying the provisions on the aerostatic pressure during the external leakage test of Class 0 components. The expert from Germany introduced GRSG-103-24 to amend and correct the current text of UN Regulation No. 67. GRSG adopted both documents, as reproduced in Annex II to this report, and requested the secretariat to submit the amendments to WP.29 and AC.1 for consideration at their March 2013 sessions as draft Supplement 12 to the 01 series of amendments to UN Regulation No. 67.
21. The expert from Germany presented ECE/TRANS/WP.29/GRSG/2012/18 clarifying the provisions of UN Regulation No. 67 with respect to hose assemblies. The expert from AEGPL supplemented the proposal with additional amendments as listed in ECE/TRANS/WP.29/GRSG/2012/19. GRSG noted some concerns and decided on the need to further clarify the responsibility and conformity of production procedures. Following the discussion, GRSG agreed to resume consideration of this subject at its next session on the basis of a revised proposal by Germany. GRSG recommended keeping ECE/TRANS/WP.29/GRSG/2012/18 and ECE/TRANS/WP.29/GRSG/2012/19 on the agenda as reference documents.
22. The expert from CLEPA introduced ECE/TRANS/WP.29/GRSG/2012/24 proposing new requirements for Liquefied Petroleum Gas (LPG) fuel selection systems. The expert from AEGPL presented GRSG-103-06 amending the proposed paragraphs. GRSG noted general support and some comments. GRSG agreed to resume consideration of this subject at its next session on the basis of a revised proposal by AEGPL/CLEPA, taking into the comments received.
23. As mentioned under paragraph 22 above, the expert from CLEPA introduced ECE/TRANS/WP.29/GRSG/2012/25. Thus, GRSG agreed to resume consideration of this subject at its next session on the basis of a joint proposal by AEGPL, CLEPA and NGVA Europe.
24. The expert from the Netherlands reported on the outcome of the most recent expert meetings of the task force on Liquefied Natural Gas vehicles (LNG), held in Geneva on 1-2 October 2012 (GRSG-103-14). As the secretariat had not been in the position to prepare in due time the official document, he presented GRSG-103-11-Rev.1, proposing to insert into UN Regulation No. 110 new provisions for LNG vehicles. GRSG acknowledged the work done by the LNG task force and noted a number of comments. Following the discussion, the Chair invited all experts to send their written comments by the beginning of November 2012 to the LNG Secretary (jseisler@cleanfuelsconsulting.org). GRSG noted the intention of the LNG task force to present a revised proposal at the forthcoming session of the Working Party on Pollution and Energy (GRPE) in January 2013 and to consider it in detail at the next session of GRSG on the basis of an official document, taking into account the comments received.
32. The expert from Germany presented ECE/TRANS/WP.29/GRSG/2013/6 superseding ECE/TRANS/WP.29/GRSG/2012/18 and clarifying the provisions of UN Regulation No. 67 with respect to hose assemblies. GRSG adopted the document, as amended below, and requested the secretariat to submit the amendments to WP.29 and AC.1 for consideration at their November 2013 sessions as draft Supplement 13 to the 01 series of amendments to UN Regulation No. 67.
Paragraph 2.7.1., the text in square brackets, amend to read (removing the square brackets):
“The assembly instruction shall be written in the language of the country to which the type of hose or couplings will be delivered, or at least in English. It shall include detailed characteristics of equipment used for the assembly operation.”
33. The expert from CLEPA introduced ECE/TRANS/WP.29/GRSG/2013/10 proposing to introduce into UN Regulation No. 67 type approval provisions for electronic control units (ECUs). GRSG adopted the document, not amended, and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their November 2013 sessions as part (see para. 32 above) of draft Supplement 13 to the 01 series of amendments to UN Regulation No. 67.
34. The expert from CLEPA presented ECE/TRANS/WP.29/GRSG/2013/11, ECE/TRANS/WP.29/GRSG/2013/12 and GRSG-104-18 proposing to introduce into UN Regulation No. 67 type approval provisions for fuel selection systems respectively for “valve control at the stop-start function”. Recalling the discussion on the same subject under agenda item 8 on UN Regulation No. 110 (see paras. 38 and 39 below), GRSG agreed to resume consideration on this matter at its next session. In this respect, the Chair invited the expert from CLEPA to prepare, if necessary, updated proposals.
35. On behalf of the task force on Liquefied Natural Gas vehicles (LNG), the expert from the Netherlands introduced ECE/TRANS/WP.29/GRSG/2013/7 proposing to insert into UN Regulation No. 110 new provisions for vehicles using LNG in their propulsion systems. He also presented GRSG-104-34, GRSG-104-35, GRSG-104-36, GRSG-104-37 and GRSG-104-38 proposing further improvements to the text as agreed by the task force during its meeting on 15 April 2013, prior to the GRSG session. GRSG noted GRSG-104-32 justifying the need for such amendments as well as GRSG-104-33 listing a number of questions and answers on general LNG background issues.
36. GRSG acknowledged the work done by the LNG task force and considered ECE/TRANS/WP.29/GRSG/2013/7 in detail. GRSG adopted the document, as reproduced in GRSG-104-44, and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their November 2013 sessions as draft Supplement 1 to the 01 series of amendments to UN Regulation No. 110, subject to a final review of GRSG-104-44 by the Working Party on Pollution and Energy (GRPE) at its forthcoming session in June 2013, particularly on environmental issues.
37. The expert from CLEPA introduced ECE/TRANS/WP.29/GRSG/2013/10 proposing to introduce into UN Regulation No. 110 type approval provisions for electronic control units (ECUs). GRSG adopted the document, as amended, and agreed to reflect the adopted text in GRSG-104-44, mentioned above.
38. The expert from CLEPA presented ECE/TRANS/WP.29/GRSG/2013/11 proposing to introduce into UN Regulation No. 110 type approval provisions for fuel selection systems. GRSG noted a number of concerns and preferred to refer the proposal to the informal group on Gaseous Fuelled Vehicles (GFV) for detailed consideration at the forthcoming session in Brussels. GRSG agreed to resume consideration on this subject at its next session on the basis of a revised document by CLEPA.
39. The expert from CLEPA also proposed to introduce type approval provisions for “valve control at the stop-start function” into UN Regulation No. 110 (ECE/TRANS/WP.29/GRSG/2013/12). The expert from OICA presented GRSG-104-19 improving the proposed text. GRSG agreed in principle on the both proposals, but preferred again to refer the proposal to GFV for detailed review. GRSG agreed to resume consideration on this subject at its next session on the basis of a revised document by CLEPA.
34. The expert from CLEPA presented ECE/TRANS/WP.29/GRSG/2013/11, ECE/TRANS/WP.29/GRSG/2013/12 and GRSG-104-18 proposing to introduce into UN Regulation No. 67 type approval provisions for fuel selection systems respectively for “valve control at the stop-start function”. Recalling the discussion on the same subject under agenda item 8 on UN Regulation No. 110 (see paras. 38 and 39 below), GRSG agreed to resume consideration on this matter at its next session. In this respect, the Chair invited the expert from CLEPA to prepare, if necessary, updated proposals.

GRSG agreed to resume consideration on this subject at its next session on the basis of a revised document by CLEPA.
20. CLEPA is asking for a simplification so that no separate R 110 or R67/01 type approval of the electronic control unit is required if the ECU is approved against R. 10 (regulation for electromagnetic compatibility) requirements through an EMC “vehicle approval”. The vehicle type approval shall also be pursuant to the applicable provisions laid down in the relevant annexes of gas Regulations (R.110 and R. 67/01). (Please see ECE/Trans/WP.29.GRSG/2013/10)
21. Though this topic is a GRSG (Group of Experts on General Safety) topic the GFV engaged in the discussion because the expertise for gaseous fuel vehicles is deeper with the GFV than the GRSG.
22. Mssrs. Dekker and Renaudin expressed concerns with the amendment as constructed, but not necessarily the language in the proposed amendment.
23. In particular, proposals for amendments concerning “fuel selection system” should apply to the gas system as a whole and not only to the “selection system” (please see ECE/Trans/WP.29.GRSG/2013/11)
24. Proposals for amendment ECE/Trans/WP.29.GRSG/2013/12 aims to allow the safety valves to remain open during Start-&-Stop phases. If the automatic valves are closed during activated stop phases, as a consequence of a more intensive operation of such valves, one of the following shall apply: a) a functional check for each valve shall be carried out once in a driving cycle. In the event that the functional check indicates that the valve is not closing, an indicator shall clearly inform the driver; or b) the valves shall comply with more stringent test cycling.
25. New requirements for test cycling now would be from 200,000 to 1,000,000, and this also is a fundamental change to the regulation. Furthermore, the cycle numbers are linked to the Start-&-Stop strategies, such as normal S-&-S, hybrid electric and S-&-S with coasting. But no definitions are proposed for these systems.
26. Mr. Rijnders asked a fundamental question about the procedure to communicate the discussion here at GFV to the GRSG and CLEPA. In principle GFV agreed with the intention of the amendment but there is concern about the actual language being used. There are several possibilities for GFV: 1) do nothing; 2) request CLEPA to improve the text of the document; or 3) ask a contracting party to improve the text in the GRSG as an informal document.
27. The decision is that Mr. Piccolo, as co-secretariat of GFV, will collect and summarize the comments from GFV and supply them to CLEPA prior to the next meeting of GRSG in April 2013. But their (CLEPA) formal document will have to become an new informal document due to the extent of the changes being suggested by the GFV.
28. Mr. Renaudin added that the concept of ‘start-stop’ (and also ‘stop-start’, as also used in the text) is not properly defined. He also expressed a concern that this same language could refer to heavy duty vehicles, thus creating additional ‘loop-holes’ in the regulation.
