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.

Draft letter intended for the UN Office of Legal Affairs to handle three planned series of amendments to the proposed UN Regulation transposing GTR 15 (WLTP) simultaneously. Normally, each series of amendments to a regulation must be implemented sequentially. In the case of WLTP, the informal group is proposing to use the series of amendment to implement stringency levels based upon regional needs (e.g., 00 series for the EU, the 01 series for Japan, and the 02 series as the most stringent set of requirements). The informal group is considering a request to handle this situation differently such that the 3 initial series would be implemented simultaneously, enabling future changes in regional stringency to proceed in a timely fashion (e.g., parallel development of new series based on regional objectives).

EC proposals regarding the OICA proposal on the UN R49.06 ECU torque signal validation requirement and dual-fuel or flex-fuel vehicles.

Document GRPE/2018/3 presents a consolidated revision of UN R96 to align the UN Regulation with Regulation (EU) 2016/162 concerning gaseous and particulate pollutant emission limits and type-approval for internal combustion engines for non-road mobile machinery. This proposal presents editorial improvements and corrects the provision allowing contracting parties to require in-service monitoring of engines by explicitly excluding its application from the scope of the Regulation.

Proposal to align UN R24 (Compression Ignition Engines – Emission of Visible Pollutants – Power Measurement) with UN R85 with regard to correction factors.

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).

Revised proposal, superseding document GRPE/2018/5, to clarify the wording of the determination of the net power for electric motors and to correct an error in the formula presented in paragraph 5.4.2. Diesel engines – Factor αd. The parameter “f_m” in the equation should be a superscript (e.g., meaning “to the power of f_m”). Through a transcription error, this factor was rendered in normal text.

OICA proposal to pursue gradual harmonization of heavy-duty vehicle fuel efficiency standards, beginning with an effort to define a uniform measurement procedure through a global technical regulation.

OICA proposal to explore the possibilities for harmonizing RDE procedures adopted around the world.

Revised proposal for Amendment 4 to GTR 15 from the WLTP informal group.

Revised proposal from the WLTP informal group pursuant to GRPE-76 discussions for Amendment 4 under the Phase 2 development of GTR 15.

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.

Proposal for a new UN Rule [No. 3] on Periodical Technical Inspections of motor vehicles using Compressed Natural Gas (CNG), Liquefied Petroleum Gas (LPG) and/or Liquefied Natural Gas (LNG) in their propulsion system

[Adopted with Canada and US abstaining.]

Report on the development of Amendment 4 to GTR 15. Amendment 4 is part of the second phase development of the GTR mandated to:

1. Introduce definitions of response time, delay time and rise time harmonized with those in GTR Nos. 4 and 11
2. Introduce improvements to the gear shifting procedures
3. Ensure consistency in the use of the terms accuracy, precision, resolution, tolerance, repeatability and deviation
4. Address bi-fuel and bi-fuel gas vehicles in accordance with UN R83
5. Clearly define the appropriate positioning of payload mass (25 kg plus the mass of vehicle load)
6. Correct terminology such as “classes of rolling resistance coefficients”
7. Correct minor spelling and/or punctuation mistakes, and restructuring some paragraphs
8. orrect some equations and to make them all consistent with Word’s use of mathematical symbols
9. Exclude all Rechargeable Electric Energy Storage Systems (REESSs) that do not contribute to vehicle propulsion from monitoring
10. Better define the purity of certain gases such as nitrogen and synthetic air
11. Define more specifically the difference in mass of CO2 during charge sustaining between the test with the highest and lowest positive and negative electric energy charge

Amendment 1 to UN GTR No. 19 adds a test procedure for sealed fuel tank systems in addition to modifications related to testing of non-sealed fuel tank systems which were raised during the work on sealed fuel tank systems.

Proposal of minor corrections to the draft Amendment 1 to GTR 19 (WP.29/2018/73).

Background information on the development of Amendment 1 to GTR 19.

Proposal to establish a WP.29 program to develop a UN GTR specifying a methodology for determining the real driving emissions of light-duty vehicles based on the European RDE methodology appropriately adapted for specific regional traffic conditions and boundaries.

Proposal to improve the “random check requirement” and define the rounding of test results calculated according to Annex 4A in the 05 series of amendments.

Proposal to improve the Engine Control Unit (ECU) torque signal validation requirement in the 06 series of amendments to R49 with regard to dual-fuel or flex-fuel vehicles. Under the regulation, the ECU torque information can be calibrated only to one fuel’s heat value (usually the basic reference fuel) even though the heat value of the alternative fuel is different. In order to increase the accuracy of the torque values used for calculating the emission results during in-service conformity testing, OICA proposes to change the provisions to either:

1. Demonstrate that both fuels comply because the ODB system is able to detect the fuel used, or
2. Determine the torque deviation caused by the alternative fuel heat value compared to the standard fuel and apply this correction factor to calculate a more accurate power signal for the emission calculation.

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 wording of the determination of the net power for electric motors and to correct an error in the formula presented in paragraph 5.4.2. Diesel engines – Factor αd. The parameter “f_m” in the equation should be a superscript (e.g., meaning “to the power of f_m”). Through a transcription error, this factor was rendered in normal text.

During discussion in WLTP/DTP, 40 CFR Part 1066 was not finalized yet. Therefore, the values from text in 2011 were used in GTR15. However, the value in CFR were changed to 1.0% from 0.5%. This changes were made to harmonize with other regulations and also because CH-DY manufacturers could not comply with this value.
