Division: Formula 10 - Commission Implementing Decision (EU) 2017/785 of 5 May 2017 on the approval of efficient 12 V motor-generators for use in conventional combustion engine powered passenger cars as an innovative technology for reducing CO2 emissions from passenger cars pursuant to Regulation (EC) No 443/2009 of the European Parliament and of the Council (Text with EEA relevance)

Where:

MT

minimum threshold [g CO₂/km]

C_{{CO}_{2}}

total CO₂ saving [g CO₂/km]

s_{C_{{CO}_{2}}}

standard deviation of the total CO₂ saving [gCO₂/km]

{ΔCO}_{2_{m}}

CO₂ correction coefficient due to the positive mass difference between the efficient 12 V motor generator and the baseline alternator. For ${ΔCO}_{2_{m}}$ the data in Table 4 is to be used.

Table 4

CO₂ correction coefficient due to the extra mass

Type of fuel	CO₂ correction coefficient due to the positive mass difference ( ${ΔCO}_{2_{m}}$ )[g CO₂/km]
Petrol	0,0277 · Δm
Diesel	0,0383 · Δm

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.
