The group yesterday (16 January 2012) finalized, for the most part, a document that will be brought to the GFV (R 49 rev6 Euro VI). The exceptions are two appendices based on a document submitted to GFV in September for specific calculations, in particular, on gas measurement. OICA and TNO will be working to complete this by the end of January and it will be discussed by the HDDF TF in Brussels at the next meeting on 8th February 2012.

The document GFV 17-4 will be circulated to the GFV this week and comments can be made from this latest version.

Yesterday (16 January) the group worked mainly on editorial changes.

These details will be worked out at the next meeting of the HDDF TF on 8 February 2012 (Brussels) and another meeting early in May. The draft of R.49 amendments (v.6 Euro VI) will be prepared as a formal document from the GFV for consideration at the June 2012 GRPE meeting. Thus the Euro V/R.49 amendments (retrofits) will be delayed by six months and will consider a formal document in January 2013.

Some specific points that need consideration of the GFV are:

• ► LNG20 was considered – pure methane — (modeled after G-20, one of the emission test fuels) but then it was thought to remove LNG20 because it is not a ‘recognized’ test fuel. Mr. Renaudin suggested that an informal document be prepared on this issue and not necessarily included in the complete HDDF TF document if it would slow down the discussion/adoption of the R.49 amendments.

• ► OBD requirements.
  • A question was raised about the possibility of having two OBD systems; one for the diesel mode and another for the dual-fuel mode. This would make the system more complex (and more expensive). The intention is to look carefully at this issue and consider adding the fuel requirements and include this for discussion at the next meeting. (This comes from the fact that R.83 — light duty — allows two OBD systems.)

• ► Comment made that the regulation should include some flexibility.

GFV 17-4 will be made into a informal document for the GRPE (less a few specific comments not necessary for GRPE) from R.49. Euro V requirements are not yet included but will be included in a later version. The appendix will be included in the version drafted in February. The document will be sent by the GFV secretariat in hopes of having comments back as soon as possible for the HDDF TF to consider and to be included in an informal GFV document. Two documents will be done: GFV-17-04 will be put on the UNECE website. A ‘cleaned’ version will become the informal document for GRPE.

Mr. Rijnders will work with Mr. Albus (Chairman, GRPE) to ensure that the documents submitted and the reports from the GFV by Mr. Rijnders at the June GRPE are done in the proper order on the agenda and not under point 8 (GRPE agenda item 4) to ensure that the GFV issues are dealt with logically so that participants clearly understand the work and progress of the GFV/HDDF TF.
