Division 8: Formula to calculate the CO2 savings - Commission Implementing Decision of 27 June 2013 on the approval of the Valeo Efficient Generation Alternator 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to Regulation (EC) No 443/2009 of the European Parliament and of the Council (Text with EEA relevance) (2013/341/EU) (repealed)

The CO₂ savings are to be calculated with the following formula:

Formula (9)

C_{{CO}_{2}} = {ΔΡ}_{m} \times V_{Pe} \times CF ∕ v

Where:

C_CO₂

CO₂ savings (g CO₂/km);

ΔΡ_m

Accountable share of saved mechanical power as per formula (8) (W);

V_Pe

Willans’ factors (l/kWh);

CF

Conversion factors (g CO₂/l)

v

mean driving speed of the NEDC (km/h)

For the Willans’ factors the data in table 1 is to be used:

Table 1

Willans’ factors

Type of engine	Consumption of effective power V_Pe[l/kWh]
Petrol (V_Pe-P)	0,264
Petro Turbo	0,28
Diesel (V_Pe-D)	0,22

For the conversion factors the data in table 2 is to be used:

Table 2

Conversion factors

Type of fuel	Conversion factor (l/100 km) → (g CO₂/km)[100 g/l]
Petrol	23,3 (= 2 330 g CO₂/l)
Petro Turbo	23,3 (= 2 330 g CO₂/l)
Diesel	26,4 (= 2 640 g CO₂/l)

The mean driving speed of the NEDC is: v = 33,58 km/h
