Experimental investigation of the effects of using low ratio n-butanol/diesel fuel blends on engine performance and exhaust emissions in a turbocharged DI diesel engine

Environmental contamination has been increasing day by day due to increase in use of fossil fuel, therefore world is moving towards unconventional sources of energy generation. In this study, a diesel engine characteristic was analysed in a single cylinder, four strokes, water cooled, direction injection (DI) diesel engine by using two different fuel blends, one is non-edible oil (Moringa oleifera) and another one is alcohol (Ethanol) and operating at different engine load. Diesel engine characteristics were examined in terms of engine performance, emission and combustion characteristics by using Diesel-RK software and before that validate the numerical result with experimental result. The result shows that MB20 has reduction of 2.26%, 7.37%, 2.6%, 8.3% and 15.02% in BTE, EGT, Smoke emission, MRPR and NOX respectively and increases 8.9% and 12.34% in SFC and CO2 emission. The MBE20 has increased by 2.9% and 18.75% in SFC and CO2 emissions and decrease of 1.25%, 2.45, 5.44%, and 3.06% in BTE, EGT, MRPR and NOX respectively was found as compare to diesel fuel. In this paper, mixing various blends 20% of Moringa Oleifera biodiesel fuel with 20% of ethanol gives optimum blends ratio.

Abstract The article deals with the effects made by using various n-butanol-diesel fuel blends on the combustion history, engine performance and exhaust emissions of a turbocharged four-stroke, four-cylinder, CRDI 1154HP (85 kW) diesel engine. At first, load characteristics were taken when running an engine with normal diesel fuel (DF) to have ‘baseline’ parameters at the two ranges of speed of 1800 and 2500 rpm. Four a fossil diesel (class 1) and normal butanol (n-butanol) fuel blends possessing 1 wt%, 2 wt%, 3 wt%, and 4 wt% (by mass) of n-butanol-bound oxygen fractions were prepared by pouring 4.65 wt% (BD1), 9.30 wt% (BD2), 13.95 wt% (BD3), and 18.65 wt% (BD4) n-butanol to diesel fuel. Then, load characteristics were taken when an engine with n-butanol-oxygenated fuel blends at the same speeds. Analysis of the changes occurred in the autoignition delay, combustion history, the cycle-to-cycle variation, engine efficiency, smoke, and exhaust emissions NOx, CO, THC obtained with purposely designed fuel blends was performed on comparative bases with the corresponding values measured with ‘baseline’ diesel fuel to reveal the potential developing trends.
