A transesterification process study on the performances, emission, and combustion characteristics of sheep fat oil as biodiesel.

Abstract

The purpose of the inquiry is to evaluate the development and application of sheep fat oil as biodiesel as well as the effects of biodiesel on combustion engine efficiency and emissions The thermophysical characteristics of biodiesel derived from the transesterfication process as well as their blends from the processes were examined in a single cylinder watercooled DI Diesel engine with an eddy current dynamometer The test fuel was created using the following ratios STB 25 STB 50 STB 75 and STB 100 yielding a blend of vacation diesel fuel and sheep fat oil biodiesel The experimental results reveal a small difference when comparing the brake thermal efficiency to that of solo gasoline The emission tests were conducted using an AVL DI Gas analyzer and the findings showed that while NOx greatly decreased as compared to the sole fuel CO HC and Smoke density increased somewhat on one side The cylinder pressure and heat release rate were also measured using the AVL DI Gas Analyzer
