              3.2. RDE result evaluation factor for OVC-HEV

              The value of the RDE result evaluation factor depends on the ratio  between the distance-specific CO2 emissions measured during the RDE test and the distance-specific CO2 emitted by the vehicle over the applicable WLTP test conducted in Charge Sustaining vehicle operation including all appropriate corrections. The ratio  is corrected by a ratio reflecting the respective usage of the internal combustion engine during the RDE trip and on the WLTP test, to be conducted in charge sustaining vehicle operation.

              For either the urban or the total driving:

              where ICk is the ratio of the distance driven either in urban or total trip with the combustion engine activated, divided by the total urban or total trip distance:

              With determination of combustion engine operation in accordance with paragraph 3.6.3. of this Regulation.

              4. Final RDE emission results taking into account the PEMS margin

              In order to take into account the uncertainty of the PEMS measurements compared to the ones performed in the laboratory with the applicable WLTP test, the intermediate calculated emission values MRDE,k shall be divided by 1+marginpollutant., where marginpollutant defined in the Table A11/2.

              The PEMS margin for each pollutant is specified as follows:

       Table A11/2

Pollutant        Mass of oxides of nitrogen (NOX)  Number of particles (PN)  Mass of carbon monoxide (CO)  Mass of total hydrocarbons (THC)  Combined mass of total hydrocarbons and oxides of nitrogen (THC + NOX)

Marginpollutant  0.10                              0.34                      Not yet specified             Not yet specified                 Not yet specified

Any negative final results shall be set to zero.
Any Ki factors which are applicable, according to paragraph 8.3.4. of this Regulation, shall be applied.
These values shall be considered the Final RDE emission results for NOX and PN
