Experimental evaluation of the effects of diesel/biodiesel/N-Pentanol blends usage in a diesel engine on emission parameters in different actions. Presented at the 10th International Congress on Life, Engineering and Applied Sciences in a Changing World, August 12-14, İzmir.978-625-6879-17-1https://hdl.handle.net/11468/12601The rapid increase in global warming and the approaching depletion of fossil fuel reserves are steadily increasing the interest in alternative biofuels. Biodiesel, along with heavy and light alcohols and other biomass sources, such as bioalcohols derived from various biomass sources and vegetable oils, plays a significant role as alternative fuels. Ethers, alcohols, and esters, which are oxygenated compounds, enhance the efficiency of fuels by promoting complete combustion and exhibiting high octane/cetane values. Due to these desired properties, they stand out as suitable fuel additives. Additionally, biodiesel and alcohols belong to the class of aliphatic alcohols, which means they do not contain aromatic compounds (such as benzene and its derivatives) in their chemical structures. This offers potential additional advantages in reducing emissions of soot, particles, and toxic substances, including polycyclic aromatic hydrocarbons (PAHs). In this study, the effects of mixtures of DF, B100, and n-pentanol on emissions were investigated. The pure and blended fuels investigated in emission studies are as follows: Pure DF and pure B100, 50%/50% volume ratio diesel/biodiesel (DF50B50), 50%/50% volume ratio diesel/n-pentanol (DF50PE50), 50%/25%/25% volume ratio diesel/biodiesel/n- pentanol (DF50B25PE25), 50%/35%/15% volume ratio diesel/biodiesel/n-pentanol (DF50B35PE15), and 50%/45%/5% volume ratio diesel/biodiesel/n-pentanol (D50B45PE5). The fuels DF50B50, DF50PE50, and DF50B25PE25 reduced the smoke opacity (SO) by 80.17%, 96.69%, and 61.98%, respectively, compared to pure DF under maximum load conditions. Under the same load conditions, DF50B50, DF50PE50, and DF50B25PE25 also decreased NOx emissions by 19.18%, 32.08%, and 14.15% compared to DF, while reducing CO emissions by 23.08%, 33.85%, and 6.92%, respectively. These results indicate that the mentioned fuel blends have significantly improved the reduction of smoke opacity and emissions of nitrogen oxides (NOx) and carbon monoxide (CO) when compared to pure DF at maximum load conditions.eninfo:eu-repo/semantics/openAccessBiodieselN-pentanolHeavy alcoholFFAsTransesterificationEmissionConference Object94104
