In the case that upon request of the manufacturer the provisions defined in Article 15(5) of this Regulation are applied, the engine full load curve of that specific engine recorded in accordance with paragraph 4.3.1 shall be used as input data.

The input data shall be provided in the file format of ‘comma separated values’ with the separator character being the Unicode Character ‘COMMA’ (U+002C) (‘,’). The first line of the file shall be used as a header and not contain any recorded data. The recorded data shall start from the second line of the file.

6.1.2Full load curve

The input data shall be the engine full load curve of the engine recorded in accordance with paragraph 4.3.1.

6.1.3Motoring curve of the CO₂-parent engine

The input data shall be the engine motoring curve of the CO₂-parent engine of the engine CO₂-family defined in accordance with Appendix 3 to this Annex and recorded in accordance with paragraph 4.3.2.

In the case that upon request of the manufacturer the provisions defined in Article 15(5) of this Regulation are applied, the engine motoring curve of that specific engine recorded in accordance with paragraph 4.3.2 shall be used as input data.

6.1.4Fuel consumption map of the CO₂-parent engine

The input data shall be the values of engine speed, engine torque and fuel massflow determined for the CO₂-parent engine of the engine CO₂-family defined in accordance with Appendix 3 to this Annex and recorded in accordance with paragraph 4.3.5.

In the case that upon request of the manufacturer the provisions defined in Article 15(5) of this Regulation are applied, the values of engine speed, engine torque and fuel massflow determined for that specific engine recorded in accordance with paragraph 4.3.5 shall be used as input data.

The input data shall only consist of the average measurement values of engine speed, engine torque and fuel massflow over the 30 ± 1 seconds measurement period determined in accordance with subpoint (1) of paragraph 4.3.5.5.

The first column of the file shall be the engine speed in min^{– 1} rounded to 2 places to the right of the decimal point in accordance with ASTM E 29-06. The second column shall be the torque in Nm rounded to 2 places to the right of the decimal point in accordance with ASTM E 29-06. The third column shall be the fuel massflow in g/h rounded to 2 places to the right of the decimal point in accordance with ASTM E 29-06.

6.1.5Specific fuel consumption figures for WHTC correction factor

The input data shall be the three values for specific fuel consumption over the different sub-cycles of the WHTC – urban, rural and motorway – in g/kWh determined in accordance with paragraph 5.3.1.

The values shall be rounded to 2 places to the right of the decimal point in accordance with ASTM E 29-06.

6.1.6Specific fuel consumption figures for cold-hot emission balancing factor

The input data shall be the two values for specific fuel consumption over the hotstart and coldstart WHTC in g/kWh determined in accordance with paragraph 5.3.2.

The values shall be rounded to 2 places to the right of the decimal point in accordance with ASTM E 29-06.

6.1.7Correction factor for engines equipped with exhaust after-treatment systems that are regenerated on a periodic basis

The input data shall be the correction factor CF_RegPer determined in accordance with paragraph 5.4.

For engines equipped with exhaust after-treatment systems with continuous regeneration, defined in accordance with paragraph 6.6.1 of Annex 4 to UN/ECERegulation 49 Rev.06, this factor shall be set to 1 in accordance with paragraph5.4.

The value shall be rounded to 2 places to the right of the decimal point in accordance with ASTM E 29-06.

6.1.8NCV of test fuel

The input data shall be the NCV of the test fuel in MJ/kg determined in accordance with paragraph 3.2.

The value shall be rounded to 3 places to the right of the decimal point in accordance with ASTM E 29-06.

6.1.9Type of test fuel

The input data shall be the type of the test fuel selected in accordance with paragraph 3.2.

6.1.10Engine idle speed of the CO₂-parent engine

The input data shall be the engine idle speed, n_idle, in min^{– 1} of the CO₂-parent engine of the engine CO₂-family defined in accordance with Appendix 3 to this Annex as declared by the manufacturer in the application for certification in the information document drawn up in accordance with the model set out in Appendix 2.

In the case that upon request of the manufacturer the provisions defined in Article 15(5) of this Regulation are applied, the engine idle speed of that specific engine shall be used as input data.
