Revised proposal to introduce definitions for the terms “permanent” and “Limp-home routines” and to clarify ‘permanent emission default modes.

Revised proposal to complete the clarification of the basis of the petrol tank capacity restriction for mono fuel gas vehicles and address some administrative issues that have been highlighted during the transposition of WLTP.

Proposal to complete the clarification of the basis of the petrol tank capacity restriction for mono fuel gas vehicles and address some administrative issues that have been highlighted during the transposition of WLTP.

Proposal from the GRPE secretariat to correct omissions found in document WP.29/2018/148 (proposal for Supplement 8 to the 07 series of amendments) as adopted by WP.29. The proposal formulated as a Corrigendum was adopted in principle as document WP.29/2019/60 during the June 2019 session but is resubmitted here as a Supplement for administrative reasons.

Proposal to amend current definitions to allow fault code erasing in cold regions (< -7°C) and high altitude (> 2440m), harmonizing the definitions with those used in China and the United States.

Proposal to allow for the use of use special denominator conditions for certain components or systems. The current definitions of the specific denominators are based on engine/aftertreatment system combinations designed as one TWC for gasoline vehicles and DOC, DPF and SCR respectively NSC for diesel engines. Upcoming emission requirements will bring up additional aftertreatment components like Gasoline Particulate Filters (GPF) or new designs with more than one SCR catalyst. Such new systems or catalyst combinations might require specific conditions to enable the monitoring, especially when their purpose is designed for such conditions.

Proposal to clarify “permanent default” and “limp-home mode” in UN R83.

OICA request for clarification on the interpretation of Supplement 6 to the 07 series of amendments to UN R83 which enables the use of compliance assessments of vehicles with a reference mass less than 2,610 kg for the purposes of extending the type approval to special purpose vehicles (including armoured ones) having a reference mass exceeding 2,840 kg.

Proposals to inhibit tampering with emissions systems and to facilitate detection of such tampering.

Proposal to

1. clarify the relationship between approval levels, reference fuels and PN limits for PI vehicles and to modify the calculation formulae for determination of evaporative emissions in accordance with changes already agreed in UN GTR No. 19
2. correct errors in Working Paper 2019.08
3. expand 2019.08 to clarify the special provisions, and
4. resolve a contradiction in requirements concerning the provision of SCR reagent consumption data via the serial port of the standard diagnostic connector.
