Abstract:The coupling impacts between intake pressure and fuel physicochemical properties on hydrocarbon (HC) emission were studied through testing a modified single-cylinder compression ignition engine at the intake pressures of 120 kPa, 150 kPa and 180 kPa, fueled with pure diesel (B00), n-butanol-diesel blends with the blend ratio of 20% n-butanol-80% diesel by mass (B20) and B20 + EHN (adding 0.7% mass fraction 2-ethylhexyl nitrate (EHN) into B20) respectively. The results showed that: when ignition delay period is… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
