Performance of Anisole and Isobutanol as Gasoline Bio-Blendstocks for Spark Ignition Engines

Several countries have set ambitious targets for the transport sector that mandate a gradual increase in advanced biofuel content coming years. The current work addresses this transition and indicates two promising gasoline bio-blendstocks: Anisole isobutanol. whole value chains of these bio-components were considered, focusing on end-use performance, but also analyzing feedstock its conversion, well-to wheel (WTW) greenhouse gas (GHG) emissions costs. Three alternative fuels, namely ternary blend (15% anisole, 15% isobutanol, 70% fossil an energy basis) binary blends anisole with 30% isobutanol gasoline), tested, their drop-in applicability spark ignition (SI) engines. formulated liquid fuels performed well showed potential to brake thermal efficiency (BTE) by 1.4% average. Measured unburned hydrocarbons (HC) carbon monoxide (CO) increased average 12–29% 17–51%, respectively. However, HC CO concentrations exhaust temperatures at acceptable levels proper catalyst operation. studied estimated bring 11–22% WTW GHG emission reductions compared base gasoline. Additionally, fleet performance benefits flexi-fuel vehicles (FFV) modeled blends.
