How do I determine the emission factor value of CO2 in diesel engines Euro III?
Since there seems to be no reference value, I think you could start from some information about the fuel consumption and then use the emission factor for diesel oil.
Dear Prof. Luis,
For combustion engines, emission factors relate to the quantity of substance emitted from an engine to its power or fuel consumption and, for road transport vehicles, the distance traveled. When an emission factor related to engine power is used, the annual engine operating hours are required.
When an emission factor related to engine power is used, the annual engine operating hours are required.
Different emission factors have different units. Emission factors based on engine power are expressed as kg of substance per kWh, factors based on fuel usage are kg of substance per m3 of fuel and factors based on distance traveled are kg of substance per km traveled in the reporting year.
(MASS BALANCE APPROACH)
You can estimate the emission factor with A mass balance approach which identifies the quantity of substance going in and out of an entire facility, process or piece of equipment. Emissions can be calculated as the difference between input and output of each listed substance. Accumulation, depletion and chemical reactions of the substance within the equipment should be accounted for in your calculation.

Dear Prof. Michel Noussan
Thank very much for your information. How I relation this with for road transport vehicles?
