This document is a draft proposal of a new regulation prepared by the GFV informal working group to enable type approval of dual-fuel retrofit systems to be installed on already approved and in service heavy duty diesel engines and vehicles. GFV intends to submit a working document for the 73rd session of GRPE.

Reference Number: GRPE-72-12

Discussion(s):
Working Party on Pollution and Energy | Session 72 | 12-15 Jan 2016

Next steps for a final (working) document on Engine Dual-Fuel Retrofit Systems

14. Mr. Rijnders stressed that OEM D-F vehicles are not yet on the market so retrofit systems approval is important. The Informal Document GRPE-72-12 has been introduced to the GRPE for discussion this week. Diagrams on the application range and system family has been added to help clarify the complexities of type approval for the type approval authorities.

15. Annex 1 Appendix 4 (compliance statement) has not yet been discussed at length but is a very important element. A ‘good faith’ declaration must be made by the system manufacturer that all their systems meet the relevant emissions limits. This is added as an example and should also include the list of actual applications.

16. Text on the Installation Manual has been provided but will need further consideration.

56. The Chair of the IWG on GFV introduced a status report (GRPE-72-24) on the activities of the group. He updated GRPE on the status of information exchange on GFV related issues in other forums such as the Working Parties on General Safety Provisions (GRSG) and on the Transport of Dangerous Goods (WP.15). He presented a new draft Regulation on the requirements for the type approval of retrofit systems intended to be installed on heavy duty diesel vehicles to enable its operation either in diesel mode or in dual-fuel mode (GRPE-72-12). He mentioned that some provisions were not yet finalized and that the scope of the original version of the Regulation would include Euro V and Enhanced Environmentally friendly Vehicles (EEV). He explained that, similarly to Regulation No. 115, there should be a split between provisions at the UNECE level on the engine retrofit system and additional requirements at the national level on the examination or inspection of the complete installation of the system in the vehicle. He pointed out the complexity to consider within the new Regulation the installation manual of the engine retrofit system due to very different types and applications within heavy duty vehicles.

57. GRPE noted the intention of the IWG on GFV to submit an official document on a new Regulation on the requirements for the type approval of retrofit systems for heavy duty diesel vehicles at the next GRPE session, based on GRPE-72-12. GRPE acknowledged the work progress made by the group and noted the request for a meeting room for half a day during the GRPE week in June 2016.
