An Investigation into The Utilization of a Biodiesel Fuel Blend Supplemented with Mn(NO3)2 Additives in a CI Engine

Abstract

As it is known, due to the fact that petrol has a limited reserve, the search for renewable energy has an important place in all world states (by researchers). In this perspective, it was aimed to investigate the effect of a manganese standard solution for the improvement of combustion and other properties of biodiesel fuel. The experimental fuels had been created as follows: DF (diesel fuel), B25 (a blend of 25% biodiesel and 75% DF), and Mn100B25 (a blend of 25% biodiesel, 75% DF, and 100 ppm of Mn(NO3)2 additive). During the examination of the experimental fuels, the Mn100B25 fuel exhibited a decrease in density, viscosity, cetane index, and flash point compared to the B25 fuel. However, there was a slight improvement in the calorific value of the Mn100B25 fuel. The combustion and emission parameters were empirically investigated in a compression ignition (CI) engine operating at various load conditions and constant engine speeds. The analysis of the experimental data revealed that the Mn100B25 fuel exhibited the highest values for cylinder gas pressure, average gas pressure, and net heat release at the 6 bar bmep parameter. During analyzing the emission values, it emerged that the HC emissions of Mn100B25 fuel types exhibited 14.28% lower values compared to DF fuel under the 4 bar bmep conditions. At 4 bar bmep and 6 bar bmep, the CO emission values for DF and Mn100B25 fuels were the same; however, the emission value for B25 fuel was lower than that of the other two fuel types. As a result, it was observed that positive results were obtained by adding a mixture of biodiesel and manganese standard solution to the biodiesel fuel blend at a certain rate. As a result, it was observed that biodiesel and manganese standard solution blend can be used as an alternative fuel by adding to diesel fuel at certain ratios.
