The influence of oxygenated hydrocarbons as additives to diesel fuels on soot precursor production has been examined by using a detailed chemical kinetic reaction mechanism. N-heptane was used as a representative diesel fuel, and methanol, ethanol and dimethyl ether were used as oxygenated fuel additives. It was found that addition of oxygenated hydrocarbons reduced the production of soot precursors. In the case of fuel fraction constant, when the overall oxygen content in the fuel reached approximately 12% by mass, production of soot precursors was reduced effectively to zero due to dilution effect. On the other hand, in the case of equivalence ratio constant, it was revealed to occurring the difference for suppression effect of soot production in each fuel.
