Document Title Proposal for Supplement 5 to the 06 series of amendments to UN Regulation No. 49
Reference Number WP.29/2017/130
Date
30 Aug 2017
Summary 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.
