Δm (in Table 4) is the extra mass due to the installation of the motor generator. It is the positive difference between the mass of the efficient 12 V motor generator and the mass of baseline alternator. The mass of the baseline alternator is 7 kg. The extra mass is to be verified and confirmed in the verification report to be submitted to the type approval authority together with the application for certifications.

7.   The efficient 12 V motor generator to be fitted in vehicles

The type approval authority is to certify the CO2 savings based on measurements of the 12 V motor generator and the baseline alternator using the test methodology set out in this Annex. Where the CO2 emission savings are below the threshold specified in Article 9(1) of Implementing Regulation (EU) No 725/2011 the second subparagraph of Article 11(2) of that Regulation shall apply.
