This paragraph (paragraph 9.4.) sets out the specifications and tests of the ECU data at type approval for the purpose of in-service testing.
9.4.2. General requirements
9.4.2.1. 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 OBD system in real time and at a frequency of at least 1 Hz, as mandatory data stream information.
9.4.2.2. The output torque may be estimated by the ECU using built-in algorithms to calculate the produced internal torque and the friction torque.
9.4.2.3. 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 Regulation No. 85. In particular, any eventual corrections as regards auxiliaries shall be included in the above data stream information.
9.4.2.4. Access to the information required in paragraph 9.4.2.1. shall be provided in accordance with the requirements set out in Annex 9A and with the standards referred to in Appendix 6 to Annex 9B.
9.4.2.5 The average load at each operating condition in Nm calculated from the information requested in paragraph 9.4.2.1. shall not differ from the average measured load at that operating condition by more than:
(a) 7 per cent when determining the engine power according to UN Regulation No. 85;
(b) 10 per cent when performing the World Harmonised Steady state Cycle (hereinafter "WHSC") except for mode 1 and 13 (idle modes) according to Annex 4, paragraph 7.7.
UN Regulation No. 85 allows the actual maximum load of the engine to differ from the reference maximum load by 5 per cent in order to address the manufacturing process variability. This tolerance is taken into account in the above values.
9.4.2.6. External access to the information required in paragraph 9.4.2.1. shall not influence the vehicle emissions or performance.
9.4.2.7. If the difference between the measured torque value obtained with a declared market fuel according to paragraph 4.2.6. and the torque calculated from the information requested in paragraph 9.4.2.1. exceeds one of the values specified in paragraph 9.4.2.5. the following paragraph 9.4.2.8. applies.
9.4.2.8. A power correction factor for each additional market fuel permitted by the manufacturer 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 5 and average measured peak torque [Nm] on the market fuel declared.
9.4.3. Verification of the availability and conformity of the ECU information required for in-service testing
9.4.3.1. The availability of the data stream information required in paragraph 9.4.2.1. according to the requirements set out in paragraph 9.4.2.2. shall be demonstrated by using an external OBD scan-tool as described in Annex X.
9.4.3.2. 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.
9.4.3.3. The conformity of the ECU torque signal to the general requirements specified in paragraph 9.4.2. shall be demonstrated when determining the engine power according to Annex XIV and when performing the WHSC test according to Annex III.
9.4.3.3.1. The conformity of the ECU torque signal to the requirements of paragraphs 9.4.2. shall be demonstrated for each engine family member when determining the engine power according to UN Regulation No. 85. For this 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). If applicable, the power correction factor for the engine family according to 9.4.2.8. shall be determined with the parent engine of the engine family.
9.4.3.4. In the case where the engine under test does not match the requirements set out in Regulation No. 85 concerning auxiliaries, the measured torque shall be corrected in accordance to the correction method for power as set out in Annex 4, paragraph 6.3.5.
9.4.3.5. The conformity of the ECU torque signal is considered to be demonstrated if the torque signal remains within the tolerances set out in paragraph 9.4.2.5.
10. Penalties for non-conformity of production
10.1. The approval granted in respect of an engine or vehicle type pursuant to this Regulation may be withdrawn if the requirements laid down in paragraph 8.1. are not complied with, or if the engine(s) or vehicle(s) taken fail to pass the tests prescribed in paragraph 8.3.
