HCm is the mass of hydrocarbons emitted during the test part, in g/kmdist is the distance defined in paragraph 8.1.1.3. above;V is the <strong>to</strong>tal volume, defined in paragraph 8.1.1.4.1.,dHC is the density of the hydrocarbons at a temperature of 20 °C and a pressureof 101.3 kPa, where the average carbon/hydrogen ratio is 1:1.85;dHC = 0.577 kg/m 3 for gasolineHCc is the concentration of diluted gases, expressed in parts per million (ppm) ofcarbon equivalent (e.g. the concentration in propane multiplied by 3), corrected<strong>to</strong> take account of the dilution air by the following equation:HCc HCe HCd1 (1 )DFEquation 8-3where:HCe is the concentration of hydrocarbons expressed in parts per million (ppm) ofcarbon equivalent, in the sample of diluted gases collected in bag(s) A,HCd is the concentration of hydrocarbons expressed in parts per million (ppm) ofcarbon equivalent, in the sample of dilution air collected in bag(s) B,DF is the coefficient defined in paragraph 8.1.1.4.6. below.8.1.1.4.3. Carbon monoxideThe mass of carbon monoxide emitted by the vehicle's exhaust during the test shallbe calculated by means of the following formula:COmCOc V dCO3dist 10Equation 8-4where:COm is the mass of carbon monoxide emitted during the test part, in g/kmdist is the distance defined in paragraph 8.1.1.3.,V is the <strong>to</strong>tal volume defined in paragraph 8.1.1.4.1.,dCO is the density of the carbon monoxide at a temperature of 20 °C and a pressureof 101.3 kPa, dCO = 1.16 kg/m 3 ,COc s the concentration of diluted gases, expressed in parts per million (ppm) ofcarbon monoxide, corrected <strong>to</strong> take account of the dilution air by the followingequation:COc COe COd (1 1)DFEquation 8-5where:COe is the concentration of carbon monoxide expressed in parts per million (ppm),in the sample of diluted gases collected in bag(s) A,COd is the concentration of carbon monoxide expressed in parts per million (ppm),in the sample of dilution air collected in bag(s) B,DF is the coefficient defined in paragraph 8.1.1.4.6. below.8.1.1.4.4. Nitrogen oxidesThe mass of nitrogen oxides emitted by the vehicle's exhaust during the test shall becalculated by means of the following formula:
