Proposal to permit the use of hydrogen (H2) as fuel for emissions type approval of heavy-duty vehicles.

Proposal to permit the use of hydrogen (H2) as fuel for type approval of heavy-duty vehicles and to explicitly permit the usage of the reference fuel required for emission testing when the manufacturer applies for UN Regulations Nos. 24 and / or 49 type approval at same time.

Proposal from the PTI informal group to add the possibility to perform a particle number (PN) test on diesel cars of categories M and N into Resolution R.E.6.

Proposal to harmonize the requirements of the 06 and 07 series of amendments, align with UN R48 wording to ensure consistent type-approval test conditions with the introduction of the 08 series of amendments (to introduce the possibility to switch OFF rear position lamps and other lamps when ambient light conditions outside the vehicle are above 7,000 lux in order to avoid unnecessary fuel consumption). The aim of the document is to reach consensus to enable adoption of a proposal during the next GRPE session (88th session in June 2023).

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 add assembly plant(s) to the approval information document.

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 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 for changes to the draft amendments to the 05, 06, and 07 series per the following justifications:

1. In GRPE-86-12, the introduction of SAE J 1979-2 was proposed for Series 05, 06 and 07 of Regulation No. 83. Due to the different structure of Series 05 and 06 compared to 07, this proposal was not adopted. This proposal introduces the new standard to Series 05 and 06 and aligns the standards with Series 07.
2. The standards used for transmission of OBD information are maintained by international standardisation bodies (ISO, SAE). These standardisation body have to be informed.
3. Alignment of wording between the first sentence of paragraph 3.2.1.2. (“ambient or engine temperatures”) and the second sentence, where “or engine” was missing to avoid misunderstanding and ambiguity. Engine temperature is sometimes used as a substitute for ambient temperature. In this case, the engine temperature is evaluated once after a longer engine shut off phase. Only in this case an approval is necessary, as this is the only case, where an OBD monitor is disabled for the complete trip.
4. Align Paragraph 6.5.1.3. with GTR No. 15 to avoid ambiguity.

Proposal to harmonize the requirements of the 00, 01, 02 and 03 series of amendments to UN R154 based on the following justifications:

1. Correction of a wrong reference. In Paragraph 3. the functional requirements for the OBD system are included. Paragraph 4. describes the requirements relating to type-approval including the provisions for deficiencies.
2. For Series 02 and 03, SAE J 1979-2 was allowed as a standard for the transmission of OBD relevant information. ISO 14229 was removed from the list of allowed standard. This proposal aligns series 00 and 01 with series 02 and 03.
3. The standards used for transmission of OBD information are maintained by international standardisation bodies (ISO, SAE). The standardisation body maintaining the affected standard has to be informed.
4. Alignment of wording between the first sentence of paragraph 3.2.1.2. (“ambient or engine temperatures”) and the second sentence, where “or engine” was missing to avoid misunderstanding and ambiguity. Engine temperature is sometimes used as a substitute for ambient temperature. In this case, the engine temperature is evaluated once after a longer engine shut off phase. Only in this case an approval is necessary, as this is the only case, where an OBD monitor is disabled for the complete trip.
5. The OBD requirements for Diesel engines in Paragraph 3.3.4 of Annex C5 are limited to Level 1A. The requirements in paragraphs 6.3. (“Failure modes to be tested”) and 6.4. (“OBD system test”), are not limited to Level 1A. This proposal corrects this.
6. Align Paragraph 6.5.1.3. with GTR No.15 to avoid ambiguity.
7. Alignment with Series 01/03. Those allow the use of alternative preconditioning
   methods for Level 2.

Background: Manufacturers design OBD monitoring conditions and functionalities for market specific driving conditions. Reliable monitors need enable conditions, which run the OBD monitors under circumstances, where failure detection works properly. Those enable conditions are not for all monitors represented by a three-phase WLTC, e.g. some monitors require higher load conditions. For those monitors alternative preconditioning methods are necessary.

Proposal to promote harmonisation in use of reference fuels for testing, including hydrogen fuel, based on the following justifications:

1. The use of test fuels is permitted for certification testing of gaseous and particulate pollutants and power/smoke testing in Europe. However, other countries that have adopted and referenced UN R85 may not allow this. In this case, manufacturers have to prepare fuels with different characteristics, which is costly and requires a long time due to the current inconsistent situation.
2. We believe that the use of test fuels for gaseous and particulate pollutant measurement tests should be a priority as a precondition for the introduction of more stringent emission levels.
3. Hydrogen fuelled vehicles are covered in UN Regulation No. 83, but hydrogen is not yet covered in UN R49 and UN R85.
4. Hydrogen fuelled engines could be one complementary option to reduce CO₂ emissions of future heavy-duty vehicles.
5. Therefore, hydrogen fuel should be integrated in UN R49 and UN R85 for better alignment with UN R83.

Proposal to allow higher tolerance for pressure measurement under paragraphs 4.7 and 4.8 (+ aligned intake and exhaust) in order to avoid refusal of test due to the non-compliance of pressure accuracy and based on the low impact on the αd. Value or approach (linearity?) to be discussed.

The current format of the type approval mark illustrated in Annex A3 is not consistent with the requirements of Section 5.2.1, which may unintentionally lead to approval marks not being issued or accepted in the correct format. The proposed amendment to Annex A3 aligns the illustrated approval marks with the requirements of Section 5.2.1 and Schedule 4 of Revision 3 of the 1958 Agreement. This proposal is available with tracked changes in a pdf version and in a .docx format.
