Proposal to clarify the text with regard to the extension of approvals for category N vehicles in order to avoid a possible misinterpretation that extensions may not be granted to vehicles with a reference mass greater than the mass of the type-approved vehicle.

7. The expert from OICA introduced ECE/TRANS/WP.29/GRPE/2018/6 proposing an editorial correction that removes possible misinterpretation. GRPE adopted the proposal.

9. GRPE requested the secretariat to submit ECE/TRANS/WP.29/GRPE/2018/6 and Annex IV to the report to WP.29 and the Administrative Committee of the 1958 Agreement (AC.1) for consideration and vote at their June 2018 sessions as draft Supplements 11 and 7 to the 06 and the 07 series of amendments to UN Regulation No. 83.

Updated proposal to adapt the 06 and 07 series of amendments to Regulation No. 83 to Selective Catalytic Reduction (SCR) warning and inducement systems to current vehicles, emissions requirements and reagent infrastructure. In light of further vehicle weight reduction for CO2 optimization and the resultant use of smaller AdBlue® reagent tanks, this proposal would allow for reagent refill inducement warnings as a percentage of tank capacity or as a function of the average driving range with a complete tank of fuel.

8. The expert from OICA introduced ECE/TRANS/WP.29/GRPE/2018/7 aimed at clarifying provisions on Selective Catalytic Reduction (SCR) systems. The expert from EC proposed editorial corrections (GRPE-76-34) to ECE/TRANS/WP.29/GRPE/2018/7. GRPE adopted the proposal as reproduced in Annex IV of the session report.

Proposal to adapt the 06 and 07 series of amendments to Regulation No. 83 to Selective Catalytic Reduction (SCR) warning and inducement systems to current vehicles, emissions requirements and reagent infrastructure. In light of further vehicle weight reduction for CO2 optimization and the resultant vehicle packaging challenges, diesel cars will likely have smaller AdBlue® reagent tanks. For passenger cars, the warning indicator to refill AdBlue® has to be activated at 2,400 km of remaining reagent range which could result in very frequent refills of smaller reagent tanks. This proposal would allow for reagent refill inducement warnings as a percentage of tank capacity or as a function of the average driving range with a complete tank of fuel.

Proposal to clarify the procedures and requirements related to the selection of driving modes for testing of OVC-HEV vehicles with a mode selection switch.

10. The expert from OICA also presented GRPE-76-22 introducing GRPE-76-03 and GRPE-76-04, proposing to clarify the rules related to the selection of driving modes for testing of Off-Vehicle-Charging Hybrid Electric Vehicles (OVC-HEV). The Netherlands had some comments on the proposals GRPE-76-03 and GRPE-76-04 since the new text opens the door for interpretation plus the absence of any type approval authority confirmation. The Chair asked the cooperation of OICA and the Netherlands to work on an improved text. GRPE supported the intention of the proposal.

12. GRPE agreed to reconsider at the June 2018 session GRPE-76-03, GRPE-76-04 and GRPE-76-32. GRPE requested the experts from OICA and EC to combine the documents in one formal document.

2. amend paragraph 5.3.1.2.4. to recognize that particulate pollutant emissions measurements are no longer limited to compression ignition vehicles,
3. amend paragraph 7.4.4.3. of Annex 7 to correct a typographical error,
4. amend paragraph 3.2.1.of Annex 8 to correct an error originating with UN R83 Revision 3 (2005),

Request for guidance from Transport Malta regarding a request to fit vehicles with a device capable of generating hydrogen from water for use as fuel for in a combustion engine.

13. GRPE reviewed the letter sent by the expert from Malta (GRPE-76-17). GRPE noted the statements of some delegations informing GRPE that they faced similar requests in the past and reporting that no evidence was provided that could convince of the environmental benefits of such retrofitted systems. GRPE noted also the need to verify the safety performance of such systems as the risk caused by the presence of hydrogen onboard of road vehicle is not insignificant. Experts from the automotive industry stated that they had reviewed the performance of such systems and that, due to the regulatory pressure on the industry concerning the CO2 performance of their products, they would have introduced such technologies on their vehicles, if the benefits would have been demonstrated. They also noted that hydrogen cause damage to the materials used in engines and that the retrofitting such systems on existing vehicles not foreseen for the use on hydrogen could pose durability issues. GRPE requested the secretariat to note in the session report that GRPE has not received sufficient evidences of benefits from these systems to start regulatory activities. GRPE expressed the idea that any country willing to approve such system on the national basis may wish to take into consideration the usual emission tests (Types I, II, III, and IV), low temperature tests, the durability (including Type V) and OBD provisions.
