A simple soot particulate emission model for a computational fluid dynamics calculation is developed based on a reduced kinetic model for a combustion process of four components of fuels (n-heptane, i-octane, n-cetane and hexamethylnonane) and a production process of pyrene (A4) with soot particulate production model by a moment method. To adjust a reaction rate of acetylene addition reaction of surface of soot particle, soot yield profile of the calculation result agrees with that of experimental data. Also, soot production profile against an equivalence ratio and temperature is reasonably obtained by this model. In addition, effect of ring number of nucleation aromatic hydrocarbon on the soot production process is investigated for reduction of calculation load.
