| Abstract: | Fossil fuels fulfill a major part of the world's energy demand. Higher demand for energy, depletion of fossil fuels and environmental impacts are the key motivational factors to explore alternate energy sources. Biogas and Hydrogen seem to be the promising alternate gaseous fuels. In this paper, the performance and emission studies were performed on a stationary dual fuel engine using fuel combinations of diesel, biogas-diesel, hydrogen-diesel, and hydrogen-biogas-diesel. Experimental results reveal that the performance of dual fuel mode with hydrogen-biogas-diesel fuel improved, and emissions were reduced in comparison to the neat diesel operation. The Brake Thermal Efficiency (BThEff) was improved by 3.09%, Brake Specific Diesel Consumption (BSDC) was reduced by 71.05%, and Brake Specific Energy Consumption (BSEC) decreased by 12.13%. The emission parameters CO, HC, and NOx, were reduced by 88.09%, 5.68%, and 83.01% respectively. Injection timing, which was obtained at 21°CA BTDC, was optimized experimentally for the selected optimum hydrogen-biogas-diesel fuel. |
