Supplemental information concerning document GRPE-85-01.

Proposal to permit use of equipment conforming to UN R154 for testing under UN R83 (and by extension to UN R101 which references UN R83).

Annex B6 procedures include references to rear position and other lamps. In line with UN R48 and its 08 series of amendments which would permit switching off of rear position and other lamps when ambient light conditions are above 7,000 lux to avoid unnecessary fuel consumption, this proposal would permit ambient lighting during dynamometer operation above this threshold.

Annex 5 procedures include references to daytime running lamps and rear position and other lamps. In line with UN R48 and its 08 series of amendments which would permit switching off of rear position and other lamps when ambient light conditions are above 7,000 lux to avoid unnecessary fuel consumption, this proposal would permit ambient lighting during dynamometer operation above this threshold.

Annex 4A-Type 1 tests include references to daytime running lamps and rear position and other lamps. In line with UN R48 and its 08 series of amendments which would permit switching off of rear position and other lamps when ambient light conditions are above 7,000 lux to avoid unnecessary fuel consumption, this proposal would permit ambient lighting during dynamometer operation above this threshold.

Also applicable for R85

Proposal:

1. To ensure and promote a high level of protection for the environment and human health. The underlying purpose of paragraph 3.5.7, when read in conjunction with paragraph 5.3.4, is to ensure a high level of protection for
   environment and human health. In making clear and encouraging the proper application of these provisions, this amendment furthers the aims sought to be achieved through paragraphs 3.5.7 and 5.3.4 of the Regulation.
2. To ensure and promote consumer confidence in the quality of vehicles subject to UN GTR No. 15. Given the widespread use of defeat devices (justified or otherwise) in the preceding years, consumer confidence in regulatory regime’s ability to conform with its underlying purpose has
   dwindled. This amendment makes clear and encourages the proper application of the text of the Regulation with respect to defeat devices. In doing so, consumers will be more confident in proper application of the provision.
3. To promote legal certainty. It is recognised that it is for the members of the WP.29 to interpret the provisions of Regulations at a national level. However, it is critical that Regulations of the WP.29 are clear and precise. The addition of the term “immediate” as an adjective to the term “damage” in subparagraph (a) to section 3.5.7 would make it clear that delayed or gradual damage to the engine does not justify the use of a defeat device.

Informal document GRPE-81-29 rev 1 was submitted to GRPE in June 2020 to clarify some elements surrounding the introduction of UN Regulation No. 154. This paper is updated here to add an additional clarification of the introductory provisions in the newly adopted 02 series of amendments. This document with tracked changes in word format and pdf version is also available.

Proposal to harmonize the requirements for the determination of CO2, fuel, and electric energy consumption of the discharge requirement for OVC-HEV with an operating mode switch with its stop criterion and the preconditioning requirement with the 01 series of amendments to UN R101 and 06 and 07 series of amendments of UN R83 (Annex 14, provisions for emissions test procedures for HEV). The intention is to reach consensus towards approving a proposal during the 88th (June 2023) GRPE session.

Proposal to correct inconsistencies in the time between the measurement of the end temperature and the end of the Type 1 test at 23°C for the ATCT family criterion check and in the f_jDyno force calculation.

Proposal to introduce levels in the draft new UN Regulation on Real Driving Emissions type approvals based on the following:

1. Since RDE testing has been introduced in the European Union, there has been criticism of the difficulties encountered when planning a valid RDE test.
2. This situation would be worsened by introducing the requirement for a test to be suitable for analysis according to both 3-phase and 4-phase concepts.
3. As levels have already been introduced in Regulation No. 154 and these are becoming accepted and understood by technical services and approval authorities, the introduction of these levels in this Regulation would be a clear alignment.
4. As the temperature boundary conditions from this draft Regulation are already being transposed into European legislation, OICA members see no need to differentiate between boundary conditions for the proposed levels.
5. The inclusion of these few amendments would return the planning burden to that currently experienced in the EU, at least for markets which apply the 4-phase WLTP concept.

Proposal to clarify and improve the text of the new Real Driving Emissions type approval regulation per the following justifications:

1. In paragraph 3.3.7. the text in brackets is a repeat of content in an Annex. It is good practice to keep definitions to one sentence where possible. Adding “of the tested vehicle” avoids any confusion with family test mass definitions.
2. The syntax of the term “power-to-mass-ratio” (with hyphens between all words) should be consistent throughout the document.
3. Where a requirement only applies to the approval authority which issued the approval this should be made clear in the text.
4. Additional to the technical specifications listed in Annex 5, the Regulation assumes measurement accuracy of PEMS equipment. It therefore appears reasonable that the PEMS equipment is required to also deliver these measurement accuracy.
5. As vehicles are designed to be driven predominantly forwards, and rearwards driving although normal practice is an exceptional situation, the possibility to drive rearwards for extended periods should be removed.
6. “Velocity” as a physical term is a vector and has to be accompanied by a direction. For clarity this should be replaced with “speed”.
7. A large (> 20 K) ambient temperature difference between one day and the next is not representative of real life and can result in unrepresentative catalyst performance. The possibility of a preconditioning at 23 °C followed by a test at below freezing should therefore be removed.

Proposal for a task force to identify regulatory aspects that can be improved to make tampering more difficult and easier to detect, along with the identification and definition of the most effective methods to detect tampering.
