be calculated according to Annex 6.  The number of operating cycles (d) measured for complete regeneration shall be recorded.

       3.3. Calculation of the combined carbon dioxide emission and fuel consumption

        n  2 ;

        where for each carbon dioxide emission and fuel consumption considered:
              M'sij = mass emissions of CO2 in g/km and fuel consumption in l/100 km over one part (i) of the operating cycle (or equivalent engine test bench cycle) without regeneration
              M'rij = mass emissions of CO2 in g/km and fuel consumption in l/100 km over one part (i) of the operating cycle (or equivalent engine test bench cycle) during regeneration. (when n>1, the first Type I test is run cold, and subsequent cycles are hot)
              Msi = mean mass emissions of CO2 in g/km and fuel consumption in l/100 km over one part (i) of the operating cycle without regeneration

              Mri = mean mass emissions of CO2 in g/km and fuel consumption in l/100 km over one part (i) of the operating cycle during regeneration
              Mpi = mean mass emission of CO2 in g/km and fuel consumption in l/100 km
              N = number of test points at which emissions measurements (Type I operating cycles or equivalent engine test bench cycles) are made between two cycles where regenerative phases occur,  2
              d = number of operating cycles required for regeneration
              D = number of operating cycles between two cycles where regenerative phases occur

 For exemplary illustration of measurement parameters see figure 10/1.
        Figure 10/1:  Parameters measured during carbon dioxide emission and fuel consumption test during and between cycles where regeneration occurs (schematic example, the emissions during 'D' may increase or decrease)

       3.4. Calculation of the regeneration factor K for each carbon dioxide emission and fuel consumption (i) considered

       Ki = Mpi / Msi

        Msi, Mpi and Ki results shall be recorded in the test report delivered by the Technical Service.

        Ki may be determined following the completion of a single sequence.
