ANNEX I U.K. ADMINISTRATIVE PROVISIONS FOR EC TYPE-APPROVAL

5. REQUIREMENTS AND TESTS FOR IN-SERVICE TESTING U.K.

5.1. Introduction U.K.

This Section sets out the specifications and tests of the ECU data at type-approval for the purpose of in-service testing.

5.2. General Requirements U.K.

[F1 5.2.1. For the purpose of in-service testing, the calculated load (engine torque as a percentage of maximum torque and the maximum torque available at the current engine speed), the engine speed, the engine coolant temperature, the instantaneous fuel consumption, and the reference maximum engine torque as a function of engine speed shall be made available by the ECU in real time and at a frequency of at least 1 Hz, as mandatory data stream information.] U.K.

Textual Amendments

F1 Substituted by Commission Regulation (EU) No 133/2014 of 31 January 2014 amending, for the purposes of adapting to technical progress as regards emission limits, Directive 2007/46/EC of the European Parliament and of the Council, Regulation (EC) No 595/2009 of the European Parliament and of the Council and Commission Regulation (EU) No 582/2011 (Text with EEA relevance).

5.2.2. The output torque may be estimated by the ECU using built-in algorithms to calculate the produced internal torque and the friction torque. U.K.

5.2.3 The engine torque in Nm resulting from the above data stream information shall permit a direct comparison with the values measured when determining the engine power according to Annex XIV. In particular, any eventual corrections as regards auxiliaries shall be included in the above data stream information. U.K.

5.2.4. Access to the information required in point 5.2.1 shall be provided in accordance with the requirements set out in Annex X and with the standards referred to in Appendix 6 to Annex 9B to UN/ECE Regulation No 49. U.K.

5.2.5. The average load at each operating condition in Nm calculated from the information requested in point 5.2.1 shall not differ from the average measured load at that operating condition by more than: U.K.

(a)

7 % when determining the engine power according to Annex XIV;

(b)

[F2 10 % when performing the World Harmonised Steady state Cycle (hereinafter ‘ WHSC ’ ) test in accordance with Annex III, except for mode 1 and 13 (idle modes).]

Textual Amendments

F2 Substituted by Commission Regulation (EU) 2018/932 of 29 June 2018 amending Regulation (EU) No 582/2011 as regards the provisions on testing by means of portable emission measurement systems (PEMS) and the requirements for universal fuel range type-approval (Text with EEA relevance).

The UN/ECE Regulation No 85(1) allows the actual maximum load of the engine to differ from the reference maximum load by 5 % in order to address the manufacturing process variability. This tolerance is taken into account in the above values.

5.2.6. External access to the information required in point 5.2.1 shall not influence the vehicle emissions or performance. U.K.

[F3 5.2.7. If the difference between the measured torque value obtained with a declared market fuel and the torque calculated from the information requested in point 5.2.1 exceeds any of the values specified in point 5.2.5, a power correction factor for each additional market fuel permitted by the manufacturer in accordance with point 1.1.2 shall be determined for the engine family. The correction factor shall be calculated as the ratio between average measured peak torque [Nm] on the reference fuel according to Annex IX, and average measured peak torque [Nm] on the market fuel declared.] U.K.

Textual Amendments

F3 Inserted by Commission Regulation (EU) 2018/932 of 29 June 2018 amending Regulation (EU) No 582/2011 as regards the provisions on testing by means of portable emission measurement systems (PEMS) and the requirements for universal fuel range type-approval (Text with EEA relevance).

5.3. Verification of the availability and conformity of the ECU information required for in-service testing U.K.

5.3.1. The availability of the data stream information required in point 5.2.1 according to the requirements set out in point 5.2.2 shall be demonstrated by using an external OBD scan-tool as described in Annex X. U.K.

5.3.2. In the case where this information cannot be retrieved in a proper manner, using a scan-tool that is working properly, the engine is considered as non-compliant. U.K.

[F2 5.3.3. The fulfilment of the requirement referred to in point 5.2.5 shall be demonstrated for the parent engine of an engine family when determining the engine power in accordance with Annex XIV and when performing the WHSC test in accordance with Annex III and off-cycle laboratory testing at type-approval in accordance with Section 6 of Annex VI. U.K.

5.3.3.1. The fulfilment of the requirement referred to in point 5.2.5 shall be demonstrated for each engine family member when determining the engine power in accordance with Annex XIV. For that purpose, additional measurements shall be performed at several part load and engine speed operating points (for example at the modes of the WHSC and some additional random points).] U.K.

[F3 5.3.3.2. If applicable, the power correction factor for the engine family, as referred to in point 5.2.7, shall be determined with the parent engine of the engine family.] U.K.

[F1 5.3.4. In the case where the engine under test does not match the requirements set out in Annex XIV concerning auxiliaries, the measured torque shall be corrected in accordance with the correction method set out in Annex 4 to UNECE Regulation No 49.] U.K.

5.3.5. The conformity of the ECU torque signal is considered to be demonstrated if the torque signal remains within the tolerances set out in point 5.2.5. U.K.
