    Abstract

    Fuels derived from biomass waste are of great interest because of their availability and renewable potential. Also, the depletion of fossil fuels and the subsequent search for new alternative fuels opened up a new arena of biomass research. Sweet lime oil (SLO), which is a waste biomass left from sweet lime fruit peel (Citrus limetta) contains flammable oil. The present work focuses on testing and promoting SLO as an alternative fuel in a diesel engine. Extracted SLO is blended with diesel in various proportions; the various test fuels used are a blend of 10 % SLO with 90 % neat diesel (denoted as SLO10), a blend of 20 % SLO with 80 % neat diesel (SLO20), a blend of 40 % SLO with 60 % neat diesel (SLO40), and 100 % SLO (SLO100). Experiments were conducted using a single-cylinder, constant speed, direct injection diesel engine at different load conditions. Outcomes were compared to conventional diesel fuel throughout the load. The results indicate that SLO100 has better results than the other test blends, with 33 % brake thermal efficiency. SLO diesel blends exhibited lower carbon monoxide and hydrocarbon emissions with comparatively higher carbon dioxide emissions with respect to neat diesel fuel. Oxides of nitrogen are higher for all SLO blends, especially SLO100, compared to neat diesel. The peak cylinder pressure for SLO100 and the peak heat-release rate for SLO10 is greater than that of other test fuels. It was concluded that SLO100 can be used in a direct injection diesel engine without any engine modifications.
