Abstract:
In the present comparative study, the biodiesel was produced from four non-edible seed oils sourced from Pongamia Pinnata, Scleropyrum Pentandrum, Calophyllum Inophyllum, Hevea Brasilensis Plants, and Waste Cooking Oil (WCO) from local hotels. The property of the biodiesel is determined by the fatty acid components of the base oil. When the fatty acid esters are formed, the individual fatty acid ester contributes to the overall fuel property of the biodiesel. If the physical property relationship is understood, then the desired quality biodiesel can be obtained by blending different proportions of fatty acid alkyl esters. Ultimately, the expected quality of biodiesel must perform the best in the engine. Based on this concept, the hybrid blends were prepared, and their important physical properties were compensated using a combination of biodiesels. To study the effect of hybrid blending, i.e., the internal mixing of biodiesels, a combination of hybrid blends with complementary fuel properties was obtained by mixing Pongamia (P100), Waste cooking oil (W100), Scleropyrum (S100), Calophyllum (C100), and Hevea (H100) biodiesels, referred to as PWSCH blends. The 10% and 20% individual and combination of these blends were investigated for engine performance, combustion, and emission characteristics on a single cylinder, four-stroke, direct injection, Compression Ignition (CI) Diesel Engine, and these data were compared with pure petroleum diesel characteristics. It was found that the hybrid blending technique can be applied to compensate for fuel properties, and a lower percentage of hybrid blends can be utilized in CI engines along with conventional biodiesel blends.
