| description | This article presents the results of a study of energy and ecological indicators at different engine loads (<i>BMEP</i>) adjusting the Start of Injection (<i>SOI</i>) of a Compression Ignition Engine fuelled with blends of diesel (D), rapeseed methyl ester (RME)-based biodiesel and isopropanol (P). Fuel blends mixed at D50RME45P5, D50RME40P10 and D50RME30P20 proportions were used. Alcohol-based fuels, such as isopropanol, were chosen because they can be made from different biomass-based feedstocks and used as additives with diesel fuel in diesel engines. Diesel fuel and its blend with 10% alcohol have almost the same thermal efficiency (<i>BTE</i>). In further examination of energy and ecological indicators, combustion parameters were analysed at <i>SOI</i> 6 CAD BTDC using <i>AVL BOOST</i> software (<i>BURN</i> subprogram). Increasing alcohol content in fuel blends led to a reduced cetane number, which prolonged the ignition delay phase and intensified heat release in the premixed combustion phase. Higher combustion temperatures and oxygen content in the fuel blends increased NO<sub>x</sub> emissions. Lower C/H ratios and higher O<sub>2</sub> levels affected by RME and isopropanol reduced smoke emissions. |
