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.

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.

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

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)

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).

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.
