RDE Moving Averaging Window #01

3.   MOVING AVERAGING WINDOWS

3.1.   Definition of averaging windows

Eliminate follows

The periodic verification of the instruments and/or after the zero drift verification
The cold start emissions, defined according to Appendix 4, point 4.4
Vehicle ground speed < 1 km/h
Any section of the test during which the combustion engine is switched off

(t2,j - t1,j) : jth averaging window

Mco2(t2,j) - Mco2(t1,j) > Mco2, ref

Mco2(ti,j) : CO2 mass between the test start and time (t2,j) (g)

Mco2, ref : 1/2 x WLTP test result

Mco2(t2,j - Δt) - Mco2(t1,j) < Mco2, ref =< Mco2(t2,j) - Mco2(t1,j)

Δt : Data sampling time

3.2.   Calculation of window emissions and averages

Mgas,j  :  Mass or PN emissions (g/s)

Mgas,d,j : all pollutants (g/km)
Mco2,d,j ; CO2 (g/km)

Vj : average speed (km)
