IntroductionThe diesel 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 to reduce emissions from current and future diesel engines. Oxygenated fuel is a chemical compound containing oxygen. It is used to help fuel burn more efficiently and reduce certain types of air pollution. Oxygenated fuels are characterized by the following molecular conditions of the fuels: 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 removes the During soot formation, molecular bonds break into radicals at a reasonable activation energy, leading to high cetane numbers. Oxygenated blends generally improve combustion efficiency, burn rates and the ability to burn more fuel and these blends provide reduced exhaust emissions. The use of oxygenates to produce “cleaner burning” diesel fuels has been known for over fifty years. Oxygen compounds are well known for reducing particulate emissions. Low molecular weight alcohols, such as methanol, ethanol, and t-butyl alcohol, have been reported to reduce emissions. Higher alcohols, carbonates, diethers, such as diglyme, and various glycol ethers have also been reported. Of particular interest are the P-series glycol ethers, which contain both ether and a propylene glycol end group.
