Division 3.2.1

Original text. Later amendments are not shown.

Mass emissions of gaseous compounds per cycle phase shall be calculated using the following equations:

Mi,phase=Vmix,phase× ρi× KHphase× Ci,phase× 10− 6dphase

where:

Mi

  • is the mass emission of compound i per test or phase, g/km;

    • Vmix

  • is the volume of the diluted exhaust gas per test or phase expressed in litres per test/phase and corrected to standard conditions (273,15 K (0 °C) and 101,325 kPa);

    • ρi

  • is the density of compound i in grams per litre at standard temperature and pressure (273,15 K (0 °C) and 101,325 kPa);

    • KH

  • is a humidity correction factor applicable only to the mass emissions of oxides of nitrogen, NO2 and NOx, per test or phase;

    • Ci

  • is the concentration of compound i per test or phase in the diluted exhaust gas expressed in ppm and corrected by the amount of compound i contained in the dilution air;

    • d

  • is the distance driven over the applicable WLTC, km;

    • n

  • is the number of phases of the applicable WLTC.
