To meet energy demand as well as emission regulations of today’s world moved the researchers towards the use of alternative fuels such as alcohols, biofuels in CI engine. Present work is to examine the performance and emission characteristics of fumigated butanol on a duel fuel mode HCCI engine. Experiments were performed for n-butanol fumigation (nBF) at constant speed 1500rpm with fixed mass flow rate under varying engine loads at compression ratio 17.5:1 and injection pressure 210 bar. Obtained test results showed that the mechanical efficiency increased by 7-8%, brake thermal efficiency increased by 7-13%, specific fuel consumption decreased by 4-10%. Emissions like smoke, oxides of nitrogen decreased significantly however carbon monoxide & hydrocarbons increased compared to diesel fuel. Finally, it is concluded that nBF method is best suitable for CI engines at medium engine loads for better engine efficiency and less smoke and NOx emissions.
Key words: n-butanol fumigation / Duel fuel HCCI engine / Alternative fuels / Performance / Gaseous emissions
