Proposal for amendments to the draft supplements to the 06 and 07 series of amendments to:

1. correct errors in Working Paper 2019.08,
2. expand 2019.08 to clarify the special provisions, and
3. resolve a current contradiction of requirements concerning the provision of SCR reagent consumption data via the serial port of the standard diagnostic connector.

Presentation raising concerns during the transition from NEDC to WLTP and proposing measures to facilitate this transition pending adoption of WLTP under the 1958 Agreement.

Proposals from the WLTP informal group to clarify and make editorial corrections to its original submission (document GRPE/2019/2).

Proposal to correct and clarify provisions of the regulation.

Proposal for amendments to the draft supplements to the 06 and 07 series of amendments to:

1. correct errors in Working Paper 2019.08,
2. expand 2019.08 to clarify the special provisions, and
3. resolve a current contradiction of requirements concerning the provision of SCR reagent consumption data via the serial port of the standard diagnostic connector.

Editorial corrections from the WLTP informal to its original submission.

This proposal amends UN Regulation No. 115 to list conditions, especially with regard to retrofit systems, to be met by indirect and direct injection vehicles to be considered as belonging to the same vehicle family. Gasoline direct injection vehicles which operate in indirect gas injection mode should be listed in the same family as indirect gasoline injection vehicles, as the applied gas injection technology is the same and provided that at least one such vehicle is tested as parent vehicle according to the requirements of this Regulation.

Proposal to allow an alternative test method to “set the charge air cooler outlet temperature during bench test to temperature which was observed by vehicle test and corrected to the reference temperature specified in paragraph 5.2.1.” of Annex 5. This alternative method is well recognized in SAE J1349.

The objective of this document is to provide recommendations for the minimum quality of market fuels (i.e. gasoline and diesel) that should be introduced in parallel, and at the same time, with the corresponding emissions standards.They complement the motor vehicle and NRMM pollutant emission standards that a country or a region may be considering to introduce, or to update

Amendments to GTR (WLTP) as approved by GRPE based upon documents GRPE/2019/2 and GRPE-78-25/Rev.1. The amendment package will be sent to WP.29 for consideration during its June 2019 session.

Amendment 2 to UN GTR No. 19 (WLTP EVAP) as approved by GRPE based upon documents GRPE/2019/4 and GRPE-78-28.

Document prepared by the GRPE chair and secretariat to propose areas for short, medium, and long-term attention.

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

“On Emission of Particulate Matters Less Than 10 Microns to Air Environment of Large Cities and Megalopolises During Operation of Vehicles”, translated from the original documents in Russian (pdf format and .docx format).

Request to extend mandate WLTP Informal Working Group and for guidance on future work plan.

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.

Update on the status of work regarding the transition from NEDC to WLTP, particularly pending the transposition of GTR 15 into one or more UN Regulations under the 1958 Agreement.

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

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.

This document is also available with tracked changes: pdf format and word format.

Consolidated document to inform and update the GRPE on phase 1 of the OBD2 program.

Proposal to allow an alternative test method to “set the charge air cooler outlet temperature during bench test to temperature which was observed by vehicle test and corrected to the reference temperature specified in paragraph 5.2.1.” of Annex 5. This alternative method is well recognized in SAE J1349.

Proposal to further harmonize test procedures for two-wheeled vehicles equipped with conventional combustion engine technology, including restructuring to dedicate separate sections to test types I (tailpipe emission after cold start), II (idle / free acceleration emissions) and VII (energy efficiency). The amendment aligns the GTR with technological progress, including changes related to

1. reference fuels
2. temperature conversion
3. forced induction systems (turbo/super-chargers)
4. treatment of open/closed systems
5. test room humidity
6. CO₂ tolerance, and
7. reference mass of the vehicle.

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 for a new 00 series of amendments to a new UN Regulation on uniform provisions concerning the approval of light duty passenger and commercial vehicles with regards to criteria emissions, emissions of carbon dioxide and fuel consumption and/or the measurement of electric energy consumption and electric range (WLTP). The 00 series of amendments contains two levels against which approvals can be granted; Level 1A which relates to vehicles tested using a 4-phase WLTC; and Level 1B for vehicles tested on a 3-phase WLTC.

Proposal for a new 01 series of amendments to a new UN Regulation on uniform provisions concerning the approval of light duty passenger and commercial vehicles with regards to criteria emissions, emissions of carbon dioxide and fuel consumption and/or the measurement of electric energy consumption and electric range (WLTP)

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

Proposal to permit the usage of the gaseous reference fuels described in UN Regulation No. 83 in order to reduce potential testing complexity.

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

Proposal to adapt the provisions in UN R101 to allow the usage of road load powers which have been derived from those determined in accordance with UN GTR No. 15 (WLTP).

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.

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