Emission problems associated with the use of fossil fuels have led to numerous research works on the use of renewable fuels. The aim of this study is to evaluate the effects of blends containing croton oil (CRO), 1-butanol (BU), and diesel (D2) on the engine performance, combustion, and emission characteristics. Samples investigated were 20% CRO-80% D2, 15% CRO-5% BU-80% D2, and 10% CRO-10% BU-80% D2, with D2 as the baseline. The density, viscosity, cetane number, and contents of carbon, hydrogen, and oxygen were measured by ASTM standards. A four-cylinder turbocharged direct-injection diesel engine was used for the tests. It was observed that the brake specific energy consumption of blends was found to be high compared to that of the D2 fuel. The addition of BU in the blend reduces the brake thermal efficiency values. BU-containing blends show peak cylinder pressures and heat release rates comparable to those of D2 on higher engine loads. Carbon dioxide and smoke emissions of the BU blends were lower in comparison to those of the D2 fuel.
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.
