UN R96 — 05 series of amendments

The Regulation now covers all engines of the paragraph 1.1. categories installed or intended to be installed in category T vehicles and non-road mobile machinery. Before, it covered gaseous and particulate pollutants from C.I. engines with an installed net power higher than 18 kW but not more than 560 kW. The title no longer says “compression ignition (C.I.)” engines. Paragraph 1.1. sets out the engine categories NRE, NRG, NRSh, NRS, SMB and ATS, divided into the sub-categories in Appendix 1. New paragraph 1.2. excludes monitoring of emissions from engines operated in category T vehicles or non-road mobile machinery over their normal patterns, conditions and payloads.

The applicant must give the Type Approval Authority an information folder, which includes an information document. The information folder may be on paper or in an electronic format that the technical service and the Type Approval Authority accept. The type-approval number is now followed by the engine category identification code, a slash and the Fuel Type Code (Appendix A.1 to Annex 3). Before, an additional two-letter symbol gave the emission level (a letter from D to R) and variable-speed (A) or constant-speed (B) operation. In addition to the approval mark, approved engines must bear markings that include the unique engine identification number and the engine production date. If the statutory marking is not visible without removing parts, the vehicle manufacturer must affix a visible duplicate to the vehicle or machinery.

Appendix 2 now gives the Stage V exhaust emission limits in Tables 13 to 18, one table for each engine category. Table 13 also sets a PN limit for sub-categories NRE-v-3 to NRE-v-6 and NRE-c-3 to NRE-c-6. Before, the table in paragraph 5.2.1. gave limits for carbon monoxide, hydrocarbons, oxides of nitrogen and particulate matter for each power band. Under paragraph 5.1.1., emissions must be effectively limited throughout the emission durability period in Appendix 3 and under normal conditions of use. Before, the paragraph said throughout the normal life of the engine. Paragraph 5.1.3. lists the reference fuels or fuel combinations for the tests, as appropriate, in accordance with Appendix 4.

Annex 4 now has the title “Test procedure”, and Annex 5 now has the title “Method for data evaluation and calculation”. Before, Annex 4A gave the measurement methods for power bands up to P, and Annex 4B for power bands Q and R. On request of the manufacturer and with Type Approval Authority agreement, Annex 4B could also be used for power bands up to P. Annex 4 now has appendices on particle number emissions measurement equipment and on procedures for the measurement of ammonia.

Annex 7 now gives technical requirements for dual-fuel engines operated simultaneously on both a liquid and a gaseous fuel (dual-fuel mode). Annex 9 now has requirements with regard to emission control strategies, NOX control measures and particulate control measures. Annex 9 now defines the on-board Particulate Control Diagnostic system (PCD) and the Particulate Control Malfunction (PCM). New Appendix A.3 to Annex 9 gives technical details for prevention of tampering. Where an ECU is part of the emission control system, the manufacturer must describe to the approval authority how it prevents ECU tampering and modification.

OEMs must install approved engines in non-road mobile machinery as the manufacturer instructs, without adverse effect on gaseous and particulate pollutant emissions. An OEM that ignores these instructions, or modifies the engine during installation with an adverse effect on emissions, counts as a manufacturer for this Regulation. Manufacturers must give OEMs the CO2 emissions value from type-approval and instruct them to pass it, with information on the test conditions, to the end-user. The engine family must comply with the criteria in Annex 10, and the parent engine is selected in accordance with Annex 10. Conformity of production procedures include an initial assessment of quality management systems and product conformity arrangements. Paragraph 10.2. now calls a change of particulars in the information package without repeated inspections or tests a ‘revision’.

Paragraph 12. now gives, for each engine category, dates for type-approval of engines and for placing on the market of engines and vehicles. From these type-approval dates, Contracting Parties applying this Regulation may refuse type-approvals to engine types or families not meeting the 05 series. From the placing on the market dates, they may also refuse the placing on the market of engines not approved under the 05 series. For engines intended for export under previous requirements, paragraph 12.4. now adds that markings must keep the format of the relevant series of amendments. Paragraph 12.5. lets Contracting Parties continue to grant approvals to engines that comply with any previous series of amendments, or any level. The engine must be intended as a replacement for an existing engine of the same or a less stringent emission level in an in-use vehicle.
