IntroductionDiesel engine dominates the field of commercial transportation and agricultural machinery due to its superior fuel efficiency. However they emit more emissions. The use of oxygenated fuels appears to be a promising solution towards reducing emissions in existing and future diesel engines. Oxygenated fuel is a chemical compound containing oxygen. It is used to help fuel burn more efficiently and to reduce certain types of air pollution. Oxygenated fuels are characterized by the following molecular fuel conditions: molecular weights are low and the molecules have high hydrogen/carbon ratios and a low number of carbon/carbon bonds which reduce the formation of solid carbon particles, the molecules contain oxygen which suppresses soot formation, molecular bonds break into radicals with reasonable activation energy leading to high cetane numbers. Oxygenated blends typically improve combustion efficiency, burn rate, and the ability to burn more fuel and offer reductions in exhaust emissions. The use of oxygen to produce “cleaner burning” diesel fuels has been known for over fifty years. Oxygenates are known to reduce particulate emissions. Low molecular weight alcohols, such as methanol, ethanol, and t-butyl alcohol, have been reported to reduce emissions. Higher alcohols, carbonates, dieters, such as diglyme, and various glycol ethers have also been reported. Particularly attractive are glycol ethers of the P series, which contain both ether and a propylene glycol terminal group.
