# Commission Implementing Decision (EU) 2020/728 of 29 May 2020 on the approval of the efficient generator function used in 12 volt motor-generators for use in certain passenger cars and light commercial vehicles as an innovative technology pursuant to Regulation (EU) 2019/631 of the European Parliament and of the Council (Text with EEA relevance), Division: Formula 10

Extent: E+W+S+N.I.

Where,
MTminimum threshold [g CO2/km]
total CO2 saving [g CO2/km]
standard deviation of the total CO2 saving [g CO2/km]
CO2 correction coefficient due to the positive mass difference (Δm) between the motor-generator and the baseline alternator, calculated in accordance with Table 4
Table 4
CO2 correction coefficient due to the extra mass
Type of fuel
CO2 correction coefficient ()
Petrol/E85
Diesel
LPG
CNG
In this Table, Δm is the extra mass due to the installation of the efficient 12 volt motor-generator. The extra mass is the positive difference between the mass of the efficient 12 volt motor-generator and the mass of the 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 Secretary of State together with the application for certification.
