✦ Synopsis
The in#uence of oxygenated fuels on the soot formation process inside a burning diesel jet plume was examined using a detailed chemical kinetic reaction mechanism. Normal heptane was selected as a representative diesel fuel, and methanol, ethanol and dimethyl ether were used as oxygenated fuels. It was found that the production of soot precursors, such as small unsaturated hydrocarbons and PAHs, are dramatically reduced by the use of oxygenated fuels, leading to `soot-freea diesel jet #ame. Furthermore, there are remarkable di!erences in soot suppression e!ects between oxygenated fuels, which have the same molecular formula but di!erent structures of atomic bonded oxygen.
