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.

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.

Comprehensive amendment of document GRPE/2017/6 to align UN R49 with the latest amendments of EU Euro VI legislation (Reg. EU 2016/1718), including

1. OBD equivalency option for light commercial vehicles to be continued with step ‘D’,
2. editorial corrections (incl. keeping optional THC PEMS measurement for gas engines),
3. implementation dates in Appendix 9 table 1 (2016/1718) and Annex 3 table 1 (R49),
4. implement rejection note for retroactive applicability with regard to in-service conformity (paragraph 13.4.),
clarification of type approval provisions for ‘new vehicle types as of 2017’,
5. deletion of infeasible requirement related to the PEMS test (“…void if … no valid windows left in urban only”), second part of sentence in Annex 8, Appendix 1: A1.4.2.2.2.2.
6. deletion of inconsistency between work based window and CO2 mass based method regarding valid integration windows (A.1.4.2.2.2.2. versus A.1.4.3.1.2.2).

Swiss report on circumvention of pollution-control systems through the use of aftermarket AdBlue emulators that stop AdBlue injection while preventing detection of the failure by the engine management system.
