Abstract: In this present study, performance, combustion and emission characteristics of jamun methyl ester in a direct injection diesel engine was experimentally investigated. Fuels were tested in a single cylinder, direct injection (DI), and water cooled diesel engine. The performance parameters such as brake thermal efficiency (BTE), brake specific fuel consumption (BSFC) and exhaust gas temperature (EGT) were evaluated. The emission parameters such as carbon monoxide (CO), unburned hydrocarbons (HCs), oxides of nitrogen (NO_x) and smoke were evaluated. The combustion parameters such as cylinder pressure, heat release rate (HRR), peak pressure, rate of pressure rise, combustion duration and ignition delay were analysed. It is found that JA20 (20% JA + 80% diesel) blend showed better performance and reduced emission. However, the NO_x emission for JA20 blend is higher than diesel fuel. The experiment shows that JA20 can be used as an alternate fuel for direct injection diesel engine without any modifications.
