Exhaust emissions from a spark-ıgnition engine operating on Iso-propanol and unleaded gasoline blends. Technology, 13(3), pp. 183-188.https://hdl.handle.net/20.500.12402/3850In this study, the effect of blends of iso-propanol and unleaded gasoline on exhaust emissions of a sparkignition engine were experimentally investigated. Exhaust emission tests were conducted on a four-stroke, four cylinder and direct injection spark-ignition engine. The engine tests were performed at three-fourth throttle opening position at four various speeds in the range of 1000-4000 rpm with 1000 rpm period. The experimental results compared with unleaded gasoline showed that emissions of carbon monoxide (CO) and hydrocarbon (HC) decreased with iso-propanol-unleaded gasoline blends while carbon dioxide (CO2) emission increased.eninfo:eu-repo/semantics/openAccessAttribution-NonCommercial-ShareAlike 3.0 United StatesSI EngineIso-PropanolUnleaded GasolineExhaust EmissionsSI MotorKurşunsuz BenzinEgzoz EmisyonlarıArticle133183188
