Proposed Amendments for UNR 83.08 Series Regulations

Slide Note

This document outlines the initial draft of potential amendments for the new UNR 83.08 series focused on CO2 emissions, fuel consumption, and energy consumption monitoring in motor vehicles. It discusses expanding the scope, exclusions, current regulations, definitions, and application for approval within the regulatory framework. The content aims to provide clarity on technical requirements and conformity for vehicle type approval, emission measurements, and compliance with WLTP levels.

WLTP-24- 03e_Appendix 4 Regulation 83 08 series This document is a first draft of the potential full structure and content of a new UNR 83 08 series of amendments. It has been developed for initial discussion in the UNR Transposition Task Force Rob Gardner, TRL limited 14th September 2018

Regulation 83 08 series: Main Body Table of Contents 1. Scope Expand scope to include CO2 emissions and fuel consumption? This will be needed if there is a requirement to demonstrate compliance with Level 1a or Level 2 of UNR WLTP or if ATCT is included (rather than being in UNR WLTP) monitoring on board the vehicle the consumption of fuel and/or electric energy? Be clear as to what UNR83 08 series does not cover

Regulation 83 08 series: Main Body SCOPES OF CURRENT REGULATIONS COPIED BELOW FOR INFROMATION Scope of UNR 83 07 series 1.Scope This Regulation establishes technical requirements for the type approval of motor vehicles. In addition, this Regulation lays down rules for in-service conformity, durability of pollution control devices and On-Board Diagnostic (OBD) systems. 1.1.This Regulation shall apply to vehicles of categories M1, M2, N1 and N2 with a reference mass not exceeding 2,610 kg. At the manufacturer's request, type approval granted under this Regulation may be extended from vehicles mentioned above to M1, M2, N1 and N2 vehicles with a reference mass not exceeding 2,840 kg and which meet the conditions laid down in this Regulation. Scope of UNR 101 Revision 3 1. Scope This Regulation applies to vehicles of categories M1 and N1 with regard to: (a) The measurement of the emission of carbon dioxide (CO2) and fuel consumption and/or to the measurement of electric energy consumption and electric range of vehicles powered by an internal combustion engine only or by a hybrid electric power train, (b) And to the measurement of electric energy consumption and electric range of vehicles powered by an electric power train only. It does not apply to a category N1 vehicle if both: (a) The engine type fitted to that type of vehicle has received type approval pursuant to Regulation No. 49, and (b) The total annual worldwide production of N1 vehicles of the manufacturer is less than 2,000 units.

Regulation 83 08 series: Main Body 2. Definitions Relevant definitions from UNR 83 07 series Additional definitions from Article 2 of EU 2017/1151 as amended by 2nd Act Definitions from EU 2017/1151, Annex IIIA (RDE), Section 1.2. Definitions from EU 2017/1151, Annex XXII (Devices for monitoring on board the vehicle the consumption of fuel and/or electric energy), Section 2. Definitions needed for ATCT if that is not included in UNR WLTP

Regulation 83 08 series: Main Body 3. Application for approval Amend text in UNR 83 07 series as appropriate Include the requirement to demonstrate compliance with Level 1a of UNR WLTP (NB: this will cover the Type 1, Type 4 and Type 5 tests) 4. Approval Amend text in UNR 83 07 series as appropriate

Regulation 83 08 series: Main Body 5. Specifications and tests incl. ref to ATCT + incl. family definitions, e.g. ATCT & PEMS families Small volume manufacturers General Type 1 test only if needed for ATCT (i.e. if it is not included in UNR WLTP) Type 2 test copy paragraph 5.3.2. in 07 series Type 3 test - copy paragraph 5.3.3. in 07 series and incorporate text from Annex V of EU 2017/1151 (as amended by the 2nd Act) which allows use of NEDC and WLTP road loads see also the proposal for a new paragraph 14 for the 07 series in GRPE/2018/15 {or will this be obsolete when UNR WLTP comes into force?} Type 6 test - copy paragraph 5.3.5. in 07 series and incorporate text from Annex VIII of EU 2017/1151 (as amended by the 2nd Act) which allows use of NEDC and WLTP determined road loads) see also the proposal for a new paragraph 14 for the 07 series in GRPE/2018/15{or will this be obsolete when UNR WLTP comes into force?}

Regulation 83 08 series: Main Body 5. Specifications and tests (continued) OBD - copy paragraph 5.3.8. in 07 series and incorporate all relevant text from Annex XI of EU 2017/1151 (as amended by the 2nd Act) e.g. which allows use of NEDC and WLTP Type I/1 test cycles see also the proposal for a new paragraph 14 for the 07 series in GRPE/2018/15 {or will this be obsolete when UNR WLTP comes into force?} RDE - The information and requirements from the main body of EU 2017/1151 Annex IIIA (RDE) will be copied into the Main Body of the R83 08 where relevant. Some may be more relevant for the Part B Annex. OBFCM - Requirements for type-approval regarding devices for monitoring the consumption of fuel and/or electric energy. Use text from Article 4a of EU 2017/1151 2nd Act. Cross reference to the new Annex for OBFCM. Or does this remain as an additional EU requirement outside the Geneva regulations?

Regulation 83 08 series: Main Body & Appendices 6. Modifications of the vehicle type Standard UNR text? 7. Extensions to type approvals Align with EU 2017/1151 as amended by the 2nd Act 8. Conformity of production (COP) Type 3 & OBD [OBFCM?] TBD

Regulation 83 08 series: Main Body & Appendices 9. In-service conformity incl. Type 1 and Type 4 tests as ISC is not included in UNR WLTP? Align with EU 2017/1151 as amended by the 2nd Act Part A of EU 2017/1151 will be obsolete by the time of the introduction of the 08 series and therefore is not required in the 08 series Headings in Part B of 2nd Act: 1.
