Changes to the draft resolution from the Gaseous-Fuelled Vehicles (GFV) Informal Group.

Proposal to further develop GTR No. 15 with respect to system durability, evaporative emissions, and OBD requirements and to consider other items such as conformity of production, in-service conformity (in-use testing), crankcase emissions, emissions at idle, etc.

Proposal to incorporate the latest outcomes of discussions within the VPSD working group.

Letter expressing opposition to amending the current text of Annex 4 on fuel quality.

Presentation on Japanese plans for the integration of WLTP into national legislation.

Announcement and link to an EC survey seeking views on the impact of Regulation (EU) No 168/2013 with regard to benefits, costs and technical feasibility of the Euro 5 Environmental Step.

Summary from the GRPE secretariat’s review of Revision 7 (all valid text up to and including Supplement 7 to the 05 series of amendment) to UN Regulation 49 proposing issues with the proposed text requiring attention.

Proposed revisions to the text of document GRPE/2015/13.

Study on the durability of replacement catalytic converters.

Proposal to adapt the requirements related to fuel injection malfunction monitoring (OBD) to the current state of technology. The current requirements are kept as an option left to those manufacturers that have already agreed with their approval authority to implement a monitoring solution that differs from that specified in this proposal.

Proposal to align the requirements related to measurement equipment linearity verification in Regulation No. 49 with the provisions in Regulation No. 96.

OICA proposal to amend document GRPE/2015/9 (which provides recommendations for the minimum quality of market fuels (i.e. gasoline and diesel) that should be introduced concurrently with corresponding emissions standards). This proposal clarifies that no Contracting Party would be obligated to accept any fuel that does not meet its local standards.

Proposal to simplify the communication model (template), especially with respect to retrofitted equipment.

Proposal to correct the unit of the road load coefficient b used in the formula for the calculation of the resistance to progress force.

Proposal to align the tyre-selection criteria in the CO2 emissions/fuel consumption tests under UN R101 with those for pollutant emissions (UN R83).

Proposal for a set of uniform terms and definitions to promote consistency across powertrain-related regulations.

Proposal to avoid a redundant correction of the measured engine power of supercharged and turbocharged engines fitted with a self-correcting system for ambient conditions such as temperature and altitude. The current correction factor may yield inaccurate results for such configurations.

Proposal to clarify the determination of net power in cases where an additional fan or other method is used to maintain the temperature of the engine coolant within the prescribed range.
