Original text. Later amendments are not shown.

Msi=∑nj=1M′sijn for n ≥ 1

Mri=∑dj=1M′rijd for d ≥ 1

Mpi=Msi×D+Mri×dD+d

where for each compound i considered:

M′sij

  • are the mass emissions of compound i over test cycle j without regeneration, g/km;

    • M′rij

  • are the mass emissions of compound i over test cycle j during regeneration, g/km (if d > 1, the first WLTC test shall be run cold and subsequent cycles hot);

    • Msi

  • are the mean mass emissions of compound i without regeneration, g/km;

    • Mri

  • are the mean mass emissions of compound i during regeneration, g/km;

    • Mpi

  • are the mean mass emissions of compound i, g/km;

    • n

  • is the number of test cycles, between cycles where regenerative events occur, during which emissions measurements on Type 1 WLTCs are made, ≥ 1;

    • d

  • is the number of complete applicable test cycles required for regeneration;

    • D

  • is the number of complete applicable test cycles between two cycles where regeneration events occur.

    • The calculation of Mpi is shown graphically in Figure A6.App1/1.
