Abstract

• Recent studies have shown that biobutanol can play a significant role in a sustainable, non-petroleum-based, industrial system. In regard to the use in a spark-ignition engine, butanol blended with conventional hydrocarbon fuels can increase fuel octane rating and power for a given engine displacement and compression ratio. Several reference studies have measured performance, fuel consumption and exhaust emissions for spark-ignition engines fuelled with butanol-gasoline blends. Very few experiments have been performed on in-cylinder butanol-gasoline combustion process. In this paper, an experimental investigation was carried out in a port fuel-injection, spark-ignition engine with an external boosting device. The fuel used for the experiments was a blend of 20% of n-butanol in volume with commercial gasoline. The optical accessible engine was equipped with the head of commercial SI turbocharged engine with the same geometrical specifications (bore, stroke, compression ratio) as the research engine. The engine worked in stoichiometric mixture at 2000 rpm, medium boosting and wide open throttle. Knocking condition was realized by advancing the spark timing. In cylinder UV-visible natural emission spectroscopy was applied to follow the formation and the evolution of the principal compounds and radical species that characterize the normal and abnormal combustion process from the spark ignition until the exhaust. Particular interest was devoted to OH evolution. (literal)
