Proposal to 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.

Proposal for a new Supplement to the 06 and 07 series of amendments to Regulation No. 83:
Adopted proposal to amend provisions on Selective Catalytic Reduction (SCR) warning and inducement systems, including reagent tank capacity and level specifications.

Proposal to modify the Constant Volume Sampling system temperature sensor time response requirement.

Proposal to modify the Constant Volume Sampling system temperature sensor time response requirement.

Proposal to modify the Constant Volume Sampling system temperature sensor time response requirement.

Proposal to

1. clarify the fuel tank capacity restriction for mono-fuel gas vehicles (insertion of word “nominal” in definition of “mono-fuel gas vehicle”;
2. modify the Constant Volume Sampling system temperature sensor time response requirement;
3. allow the use of WLTP-based Ki and Deterioration Factors (DF) as well as On-Board Diagnostics (OBD) demos under UN R83 to permit use of WLTP methods and test results under UN R83;
4. align the definitions for bi-fuel vehicles align with the new definitions in UN GTR 15,
5. amend paragraph 5.3.1.2.4. to recognize that particulate pollutant emissions measurements are no longer limited to compression ignition vehicles;
6. introduce provisions for reagent tank specifications and limits for triggering warning and driver inducement systems.

Revised proposal to amend provisions on Selective Catalytic Reduction (SCR) warning and inducement systems, including reagent tank capacity and level specifications. This proposal updates the previous document GRPE-76-34 (which updated the formal proposal GRPE/2018/7).

OICA changes to its proposal to modify the Constant Volume Sampling system temperature sensor time response requirement.

Addendum from GRPE to include amendments to provisions for reagent tank specifications and limits for triggering warning and driver inducement systems to the draft Supplement 11.

Addendum from GRPE to include amendments to provisions for reagent tank specifications and limits for triggering warning and driver inducement systems to the draft Supplement 7.

Presentation proposing to amend obsolete footnotes regarding the particulate number emissions limits applicable depending upon the reference fuel selected for the test procedure.

Proposal for changes to the draft new Supplement to the 06 and 07 series of amendments to UN Regulation No. 83.

Proposal to clarify the fuel tank capacity restriction for mono-fuel gas vehicles. The definition of “mono-fuel gas vehicle” was slightly amended between the 06 and the 07 series of amendments to UN R83. This proposal aims to align the definitions across both series in order to avoid divergent interpretations.
Although the reference to a 15 liters tank has always been understood to refer to the nominal capacity of the tank, the use of the term “nominal capacity” in UN GTR No. 19 in several places other than the definition of “mono-fuel gas vehicle” can lead to other interpretations of the definition. The word “nominal” should therefore be inserted into the definition in both series of amendments.

Proposal to explicitly specify requirements related to the selection of driving modes for testing of Off-Vehicle Charging Hybrid Electric Vehicles (OVC-HEV) with a mode selection switch.

Proposal to allow the usage of WLTP-based Ki and Deterioration Factors (DF) as well as On-Board Diagnostics (OBD) demos under UN R83. The proposal allows the use of the more robust WLTP and eases testing burdens by allowing manufacturers to use WLTP test results for UN R83.

Proposal to modify the Constant Volume Sampling system temperature sensor time response requirement.

Proposal to clarify the text with regard to the extension of approvals for category N vehicles in order to avoid a possible misinterpretation that extensions may not be granted to vehicles with a reference mass greater than the mass of the type-approved vehicle.

Proposal to clarify the text with regard to the extension of approvals for category N vehicles in order to avoid a possible misinterpretation that extensions may not be granted to vehicles with a reference mass greater than the mass of the type-approved vehicle.

Proposal of amendments to:

1. align the definitions for bi-fuel vehicles align with the new definitions in UN GTR 15,
2. amend paragraph 5.3.1.2.4. to recognize that particulate pollutant emissions measurements are no longer limited to compression ignition vehicles,
3. amend paragraph 7.4.4.3. of Annex 7 to correct a typographical error,
4. amend paragraph 3.2.1.of Annex 8 to correct an error originating with UN R83 Revision 3 (2005),
5. amend paragraph 6.5.3.5. to correct a cross-reference error introduced in Amendment 1 (reference should read para. 6.5.3.3. rather than 6.5.3.2.) and should refer to the “annex” rather than the “appendix”.

Updated proposal to adapt the 06 and 07 series of amendments to Regulation No. 83 to Selective Catalytic Reduction (SCR) warning and inducement systems to current vehicles, emissions requirements and reagent infrastructure. In light of further vehicle weight reduction for CO2 optimization and the resultant use of smaller AdBlue® reagent tanks, this proposal would allow for reagent refill inducement warnings as a percentage of tank capacity or as a function of the average driving range with a complete tank of fuel.

OICA request for clarification over whether the test results should reflect the energy (fuel and electric energy) used for vehicle propulsion or the energy used for vehicle propulsion and for energy conversion (recharging the battery – fuel energy to electric energy).

Proposal to clarify the procedures and requirements related to the selection of driving modes for testing of OVC-HEV vehicles with a mode selection switch.
