Performance and Emission Characteristics of Biodiesel-Butanol Blended Fuel in Lhr Engine

The use of biodiesel as an alternative diesel engine fuel is increasing rapidly. However, due to technical deficiencies, they are rarely used purely or with high percentages in diesel engines. Therefore, in this study, we used butanol as an additive to research the possible use of higher percentages of biodiesel in a diesel engine. B۱۰۰ (۱۰۰% biodiesel) was prepared as the baseline fuel. Butanol was added to biodiesel as an additive by volume percent of ۵% ,۱۰%,۱۵% ۲۰%(denoted as B۹۵ but۵, B۹۰ but۱۰, B۸۵ but۱۵ and B۸۰ but۲۰), were used in a single cylinder, four strokes direct injection LHR engine. The effect of test fuels on brake specific fuel consumption, brake thermal efficiency, exhaust gas temperature, and NOX, smoke opacity emission was investigated. The experimental results showed that the performance and emission of LHR engine we can use of the ۱۰۰% biodiesel. Besides, the exhaust emissions for B۸۰ but ۲۰ were fairly reduced.
