Performance And Emission Characteristics Of Biodiesel-Butanol Blended Fuel In Ci Engine

摘要

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. B100 (100% biodiesel) was prepared as the baseline fuel. Butanol was added to biodiesel as an additive by volume percent of 10%, 20%, 30%, 40% (denoted as PME90 B10, PME80 B20, PME70 B30, PME60 B40) were used in a single cylinder, four strokes direct injection diesel engine. The effect of test fuels on brake specific fuel consumption, brake thermal efficiency, exhaust gas temperature, and NO_X, smoke opacity emission was investigated. The experimental results showed that the performance and emission of CI engine we can use of the 100% biodiesel PME70 B30, PME60 B40. Besides, the exhaust emissions for PME60 B40 were fairly reduced.
