ANNEX XVISupplementary provisions
ANNEX XVI Annex VI to Delegated Regulation (EU) 2017/654 is corrected as follows: (1) in point 5.2.5.6, the second paragraph is replaced by the following: ‘Where the governor installed on the engine is used the 100 % speed shall be the engine governed speed as defined in Article 1(24).’; (2) point 6.3.1 is replaced by the following: ‘6.3.1. Basis for emission measurement The basis of specific emissions measurement is uncorrected net power as defined in Article 3(25) of Regulation (EU) 2016/1628.’; (3) in point 6.3.3, the last sentence of the second paragraph is replaced by the following: ‘The power absorbed by auxiliaries shall be used to adjust the set values and to calculate the work produced by the engine over the test cycle in accordance with point 7.7.1.3 or point 7.7.2.3(b).’; (4) in point 7.4.2.1, the two paragraphs below Figure 6.3 are replaced by the following: (a) point (a) is replaced by the following: ‘(a) the cold start run shall commence after either the engine and exhaust after-treatment systems have cooled down to room temperature after natural engine cool down, or after forced cool down, and the engine, coolant and oil temperatures, exhaust after-treatment systems and all engine control devices are stabilized between 293 K and 303 K (20 °C and 30 °C). The measurement of the emissions for this run shall be started with the start of the cold engine;’; (b) point (c) is replaced by the following: ‘(c) the hot-start run shall commence immediately after the soak period with the cranking of the engine. The gaseous analyzers shall be switched on at least 10 seconds before the end of the soak period to avoid switching signal peaks. The measurement of emissions for this run shall be started in parallel with the cranking of the engine. Brake specific emissions expressed in (g/kWh), or number per kilowatt-hour (#/kWh) for PN, shall be determined by using the procedures set out in this section for both the cold start run and hot-start run of the test cycle. Composite weighted emissions shall be computed by weighting the cold-start run results by 10 % and the hot-start run results by 90 % as detailed in Annex VII.’; (5) in point 7.6, the words ‘as defined in Article 2(12)’ are replaced by the words ‘as defined in Article 1(12)’; (6) in point 7.6.3.1, in point (b), the fourth and fifth sentences are replaced by the following: ‘The power recorded shall not exceed the rated power as defined in Article 3(27) of Regulation (EU) 2016/1628 by more than 12,5 %. If this value is exceeded the manufacturer shall revise the declared rated power.’; (7) in point 7.7.2.3 in the legend of equation (6-16), the second row is replaced by the following: ‘ max.torque is the maximum torque for the respective test speed taken from the engine mapping performed in accordance with point 7.6.2 adjusted where necessary in accordance with point 7.7.2.3(b).’; (8) in point 8.2.3.5, the last sentence is replaced by the following: ‘However, if a PM mass of 400 μg or more is expected, then the sample media shall be stabilised for at least 60 min.’; (9) in point 9.2.1(c), point (i) is replaced by the following: ‘(i) For removing background PM, the diluent shall be filtered with high-efficiency particulate air (HEPA) filters that have an initial minimum collection efficiency specification of 99,97 % (see Article 1(19) for procedures related to HEPA-filtration efficiencies);’; (10) in point 9.2.2(g), the last paragraph is replaced by the following: ‘For PM sampling, the already proportional flow coming from CVS goes through secondary dilution (one or more) to achieve the requested overall dilution ratio as shown in Figure 6.7 and set out in point 9.2.3.2;’; (11) in point 9.2.3.1, in the first paragraph, the last sentence is replaced by the following: ‘These need to satisfy other criteria such as in points 8.1.8.6 (periodic calibration) and 8.2.1.2 (validation) for varying dilution PFD, and point 8.1.4.5 as well as Table 6.5 (linearity verification) and point 8.1.8.5.7 (verification) for constant dilution PFD.’; (12) in point 9.2.3.3, the last paragraph is replaced by the following: ‘The system may be used also for a previously diluted exhaust gas where, via a constant dilution-ratio, an already proportional flow is diluted (see Figure 6.7). This is the way of performing secondary dilution from a CVS tunnel to achieve the necessary overall dilution ratio for PM sampling.’; (13) in Appendix 4, in point 3.4.1, the last sentence is replaced by the following: ‘The difference between the pre-test and post-test results shall be less than 2 % of full scale.’.
