‘Pi = engine power for the mode i [kW] calculated by adding to the measured power Pmeas [kW] the power required to drive auxiliaries PAUX [kW] determined in accordance with equation (6-8) of Annex VI (Pi = Pmeas + PAUX).’;

(b) in point 2.3, the first sentence is replaced by the following:

‘The final NRSC and weighted average NRTC test results shall be rounded in one step to three significant figures in accordance with ASTM E 29–06B.’.

Annex VIII to Delegated Regulation (EU) 2017/654 is amended as follows:

(1) in point 4.2.2.2, in the last paragraph, the following sentence is added:

‘A description of the connection for, and method to read, those records shall be included in the information folder as set out in Part A of Annex I of Implementing Regulation (EU) 2017/656.’;

(2) in point 4.5.1, point (b) is replaced by the following:

‘(b) In case of a Type 2 engine, the resulting difference between the highest and the lowest maximum GERcycle within the family shall never exceed the range set out in point 2.4.15 of Annex IX to Implementing Regulation (EU) 2017/656, except as permitted by point 3.1.’;

(3) point 6.4.1 is replaced by the following:

‘6.4.1. The manufacturer shall present the approval authority with evidence showing that the GERcycle span of all members of the dual-fuel engine family remains within the range set out in point 2.4.15 of Annex IX to Implementing Regulation (EU) 2017/656, or in the case of engines with an operator-adjustable GERcycle satisfy the requirements of point 6.5 (for example, through algorithms, functional analyses, calculations, simulations, results of previous tests, etc.).’;

(4) the following point 6.8 is inserted:

‘6.8. Documentation of the demonstration

A demonstration report shall document the demonstration conducted pursuant to points 6.1 to 6.7.1 The report shall:

(a) describe the demonstration performed, including the applicable test cycle;

(5) Appendix 2 is amended as follows:

(a) in point 7.1.3.2.1, the introductory wording of the first paragraph is replaced by the following:

‘In the case that the exact equations are applied to calculate instantaneous values of u gas in accordance with paragraph 7.1.3.2(a) then, when calculating the mass per test of a gaseous emission for transient (NRTC and LSI-NRTC) test cycles and RMC, u gas shall be included in the summation in equation (7-2) of point 2.1.2 of Annex VII by means of equation (8-1):’;

(b) in point 7.1.3.3, the second paragraph is replaced by the following:

Some CFV flow meters consist of a single venturi and some consist of multiple venturis, where different combinations of venturis are used to meter different flow rates. For CFV flow meters that consist of multiple venturis, either calibration of each venturi independently to determine a separate discharge coefficient, C d, for each venturi, or calibration of each combination of venturis as one venturi may be performed. In the case where a combination of venturis is calibrated, the sum of the active venturi throat areas is used as A t, the square root of the sum of the squares of the active venturi throat diameters as d t, and the ratio of the venturi throat to inlet diameters is the ratio of the square root of the sum of the active venturi throat diameters (d t) to the diameter of the common entrance to all of the venturis (D). To determine the C d for a single venturi or a single combination of venturis, the following steps shall be performed:

(a) With the data collected at each calibration set point an individual C d for each point shall be calculated using equation (7-140);

(b) The mean and standard deviation of all the C d values shall be calculated in accordance with equations (7-155) and (7-156);

(c) If the standard deviation of all the C d values is less than or equal to 0,3 % of the mean C d, then the mean C d shall be used in equation (7-120), and the CFV shall be used only down to the lowest r measured during calibration;

r = 1 – (Δp/pin) (7-148)

(d) If the standard deviation of all the C d values exceeds 0,3 % of the mean C d, the C d values corresponding to the data point collected at the lowest r measured during calibration shall be omitted;

(e) If the number of remaining data points is less than seven, corrective action shall be taken by checking calibration data or repeating the calibration process. If the calibration process is repeated, checking for leaks, applying tighter tolerances to measurements and allowing more time for flows to stabilize, is recommended;

(f) If the number of remaining C d values is seven or greater, the mean and standard deviation of the remaining C d values shall be recalculated;

(g) If the standard deviation of the remaining C d values is less than or equal to 0,3 % of the mean of the remaining C d, that mean C d shall be used in equation (7-120) and the CFV values only down to the lowest r associated with the remaining C d shall be used;

(h) If the standard deviation of the remaining C d still exceeds 0,3 % of the mean of the remaining C d values, the steps set out in points (d) to (g) shall be repeated.’;
