The following fuel composition is considered:
Component  Molar ratio  Per cent mass
H           = 1.8529   wALF = 13.45
C           = 1.0000   wBET = 86.50
S           = 0.0002   wGAM = 0.050
N           = 0.0000   wDEL = 0.000
O           = 0.0000   wEPS = 0.000

 Step 1: Dry/wet correction (paragraph 8.1. of this annex):
 Equation 16:
kf = 0.55584 × 13.45 – 0.0001083 × 86.5 – 0.0001562 ×0.05 = 0.7382
                            Equation 13:

               Equation 12:

               cCO,i (wet) = 40 x 0.9331 = 37.3 ppm

               cNOx,i (wet) = 500 x 0.9331 = 466.6 ppm

Step 2: NOx correction for temperature and humidity (paragraph 8.2.1. of this annex):
               Equation 23:

Step 3: Calculation of the instantaneous emission of each individual point of the cycle (paragraph 8.4.2.3. of this annex):
               Equation 36:

               mHC,i = 10 x 3 x 0.155 = 4.650

               mCO,i = 37.3 x 0.155 = 5.782

               mNox,I = 466.6 x 0.9576 x 0.155 = 69.26

 Step 4: Calculation of the mass emission over the cycle by integration of the instantaneous emission values and the u values from Table 5 (paragraph 8.4.2.3. of this annex):
The following calculation is assumed for the WHTC cycle (1,800 s) and the same emission in each point of the cycle.
               Equation 36:

 Step 5: Calculation of the specific emissions (paragraph 8.6.3. of this annex):
               Equation 69:

               eHC = 4.01 / 40 = 0.10 g/kWh

               eCO= 10.05 / 40 = 0.25 g/kWh

               eNOx = 197.72 / 40 = 4.94 g/kWh
