Draft amendments to the formal proposal WP.29/2017/93 submitted for the June World Forum session.

Proposal from the PTI informal working group.

Revision of document EPPR-20-05.

Presentation on the development of a testing cycle for fuel consumption/emission, including a national/regional CLTC (light-duty) and CHTC (heavy-duty), including new energy vehicles.

Information on Swiss detection of significant deactivation of Ad Blue diesel emissions reduction systems on EURO V vehicles (no EURO VI manipulated vehicles have been found to date).

Amendments as approved by the GRPE for submission to the World Forum for adoption.

Mutual resolution as approved by the GRPE for submission to the World Forum for adoption. This resolution concerns guidelines for measuring emissions of volatile organic compounds from vehicle interior materials.

Proposal to specify coolant or lubricant temperatures of at least 70°C during Type II testing. The current text specifies that the engine be “warmed up until all coolant and lubricant temperatures and lubricant pressure have reached equilibrium at operational levels.”

Proposal to correct and clarify the text, including to

1. correct the constants for equation (34) to calculate exhaust mass flow using carbon balance method,
2. correct constants used for CVS verification,
3. correct the formula for regression analysis according to Annex 4, Appendix 3, and
4. correct the rise time (to 3.5 s from 2.5 s) for the PEM analyzers under paragraph A.2.2.1. of the 06 series.

Proposal to introduce provisions to align UN R49 with recently introduced stage D EU legislation in order enable manufacturers to continue to utilize the provisions in paragraph 4 of Annex 9A to approve light commercial vehicles with a light duty OBD architecture under this regulation. This proposal incorporates all of the provisions of the latest amendment to EU legislation. As stage D is unrelated to OBD, the proposal is to make stage C and all subsequent stages equivalent to EOBD 6-2. The proposal corrects

1. the constants for equation (34) to calculate exhaust mass flow using carbon balance method,
2. the constants used for CVS verification,
3. the formula for regression analysis according to Annex 4, Appendix 3, and
4. the rise time (to 3.5 s from 2.5 s) for the PEM analyzers under paragraph A.2.2.1. of the 06 series.

Report on the development of Amendment 3 to GTR 15 on light vehicle emissions. The amendment aims to:

1. clarify phase, cycle and vehicle class terminology to enable interpolation between different levels of downscaling, cycle classes and speed caps (resulting in modifications to WLTC cycle phases and time/speed tables),
2. improve the gear shifting procedures, including changes to gear selection and shift point determination for vehicles equipped with manual transmissions,
3. define the possible and permissible combinations of test vehicle selection and family requirements,
4. define the calculation of the average test mass during road load determination,
5. define single and double roller dynamometers, and
6. make editorial improvements.
