چکیده انگلیسی
The anti-knock quality of fuels are of vital importance for improving spark ignition (SI) engine efficiency. 2-pheylethanol (2-PE) is one of potential high-octane booster, which can be derived from lignin as a biomass component. To ascertain the possibility of 2-PE as a bio-additive in SI engines, combustion characteristics and emission performance of 2-PE addition were investigated in a downsized gasoline engine. Blending 2-PE in gasoline resulted to a decrease in cylinder pressure and heat release rate. As increase of 2-PE addition, ignition delay and combustion duration of 2-PE-gasoline become postponed, combustion phasing is retarded, and COVIMEP increased significantly. The reason is thought to be correlated with its relatively lower gas-phase reactivity and higher heat of vaporization. At elevated intake pressure, the number of knock cycles and MAPO significantly increased of SI engine,addition of 2-PE exhibits good knocking resistance because of its high octane number and physicochemical properties. For regulated gas emissions, 2-PE addition produces more unburned hydrocarbon, carbon oxide and less nitrogen oxides. The blending of 2-PE in gasoline tends to increase particle matter emissions and enlarge the particle size.
