Division 6.2.3

United Kingdom

For each measured point of the conformity of the certified CO₂ emissions and fuel consumption related properties test and its corresponding point of the type approved map, the efficiency shall be calculated with:

η_{i} = \frac{T_{out}}{i_{axle} \times T_{in}}

where:

η_i

Efficiency of the grid point from each single control area 1 to 9

T_out

Output torque [Nm]

T_in

Input torque [Nm]

i_axle

axle ratio [-]
