Informal Group on Gaseous Fueled Vehicles | Session 45 | 8 Jun 2016

6. Following GFV-43 five additional web-teleconferences and one more face-to-face meeting (GFV-44) were held to address concerns about these changes and to finalise the administrative provisions. Concerns of the European Commission and Germany were addressed and resolved despite concerns of AEGPL that the changes made the testing procedures too restrictive. The final version of the regulation was prepared as a GRPE Working Document for consideration in June 2016. ECE/Trans/WP.29/GRPE/2016/12 as well as an Informal Document containing some minor corrections (GRPE-73-04).

7. No comments were raised by the participants. The chairman concluded that the working document and the informal document tabled by the GFV to the GRPE could be adopted by the GRPE session. The Chair noted, however, that an informal GRPE document had been submitted by the AEGPL with amendments to the GRPE Dual-Fuel working document and asked an explanation from the AEGPL participants in the meeting.

8. AEGPL indicated that the recommended change comes from a number of important members and that the stringency of current version of the regulation presents a problem. They indicated that there is general agreement between their members that a good resolution must be attempted.

9. Mr. Rijnders took note of the AEGPL informal document for the GPRE and was disappointed that this initiative was not brought to the attention of the GFV informal working group. He indicated still to be positive that CP’s of the GRPE will adopt the new Dual Fuel retrofit regulation in the GRPE session tomorrow.
