Diesel engine gaseous and particle emissions fueled with diesel-oxygenate blends

► Blends of Ethanol, biodiesel and diglyme with diesel separately were tested in a CI engine. ► Difference in gaseous and particulate emissions was found for different oxygenates. ► Physical properties and chemical structure also influence particulate emissions besides the oxygen content. ► Diglyme-diesel blend can simultaneously decrease PM and NOx emissions.
