Proposal for Amendment 3 to the United Nations Global Technical Regulation No. 19 to introduce the evaporative emission test procedure for the Worldwide harmonized Light vehicles Test Procedure (WLTP EVAP).

Proposal for Amendment 3 to the United Nations Global Technical Regulation No. 19 to introduce the evaporative emission test procedure for the Worldwide harmonized Light vehicles Test Procedure (WLTP EVAP).

Amendments to the formal proposal for Amendment 3 to GTR 19 introducing new OBD provisions pursuant to the Phase 2 development of the GTR 15 WLTP emissions regulation. This document proposed during the 80th GRPE is also available in .docx format and in pdf format with the track changes showing the modifications.

The TF Chair reported on the plan for the transposition of GTR15 (WLTP) and GTR19 (Evap) into a new UN Regulation.

The Technical Report to amendment 3 gives the background to the amendment that proposes the need to modify the scope and to add procedures and requirements on Conformity of Production (CoP) as an Optional Annex. The amendment also replaces the previous cross-references to technical requirements in UN Regulation No.83 07 series with the full text of those requirements to align with UN regulation on WLTP.

Amendment to OBD requirements pursuant to the Phase 2 development of WLTP provisions.

Amendments to the global technical regulation on evaporative emissions to address:

1. Calibration requirements and intervals for test equipment;
2. Equation for the variable-volume enclosures;
3. Improvements to the text:
   1. Clarification of aged carbon canister and when to install;
   2. Clarification and review of test equipment;
   3. Clarification and review of requirements of an evaporative emission family;
   4. Clarification of “carbon canister”;
   5. Change to the term “carbon canister” used to catch depressurisation puff loss overflow.

Proposal to introduce improvements and amendments concerning the evaporative emission family definitions and the Type 4 test procedures with regard to test equipment requirements and calibrations, evaporative emission measurement enclosures, and use of variable volume SHED facilities

1. The text for this proposal is based on the CoP requirements in Section 4 of Annex I to European Commission Regulation (EU) 2017/1151, as last amended by Regulation (EU) 2018/1832.
2. The text has been edited to reflect the wording used in the GTR 15 and 19, and references to the applicable annexes and paragraphs have been revised.
3. The text is presented in the format and style of GTR, while containing all elements that will be needed for the UNR WLTP.
4. Editorial changes have been made to improve the text.
5. Issues that have to be discussed within the CoP TF are indicated in [text brackets].
6. Regional specific issues (such as for Europe on the OBFCM, eco-innovations, and family criteria for commercial vehicles etc.) are left out of this text, and will be added in a later stage.
7. The scope of vehicles is not specifically indicated in this text proposal, this is therefore identical to the scope and application specified for GTRs 15 and 19.
8. The final text proposal has to be in agreement with the outcome of discussions within the Transposition TF.
9. The administrative elements will be excluded from this text, to only reflect the technical elements for the GTRs.
