Abstract

Ethanol/gasoline blends have been studied in a spray-guided GDI engine. Tests were conducted under cold and warm conditions (20°C, 80°C). The spray images and combustion analysis show that ethanol addition results in protracted injection and an increased combustion duration. The mixture inhomogeneity increased as the ethanol content was increased, and this led to slower combustion and increased levels of cycle-by-cycle variations in combustion. For stoichiometric mixtures, as the ethanol content was increased, both the particulate emissions increased but for rich mixtures the Particulate number emissions were at least an order of magnitude lower than the base fuel.
