Informal Group on Gaseous Fueled Vehicles | Session 34 | 3 Jun 2014
Geneva
Agenda Item 4.
Gaseous fuel issues at GRPE

4. There was a new document for GRPE from OICA (69-7e, amendment language and PowerPoint version 69-8, slide 7) on LNG trucks. Mr. Renaudin presented the summary of the document.

5. Alternative service mode for LNG dual-fuel vehicles currently states that the vehicle speed of a D-F truck should be limited to 20 km per hour when there is no longer gas in the LNG tank.rThe new proposal indicates to ‘Limit the power of the engine to 20% of the declared maximum power in D-F mode. It would apply only in the case when the gas has been drained out for repair reasons and would apply only to Type A dual-fuel engines (no diesel mode allowed). The rationale was that there is very poor density of LNG filling stations in some areas that would require a truck to be either towed or to operate over a long distance at 20km/h; both situations being undesirable.

6. There were no further comments and Mr. Rijnders concluded that there was consensus in the GFV regarding this amendment. He indicated it will be appropriate for OICA to mention this in their presentation at this week’s GRPE.
