An investigation Performances, Emission and Combustion Characteristics on Sheep Fat oil as Biodiesel with help of Ultrasonic assisted Transesterification Process

M.Selvam, C.Ananda Srinivasan

The aim of the study is to evaluate the effective production and utilization of Sheep fat oil as biodiesel and investigate the authority of biodiesel over the engine performance, Emission and combustion characteristics. The work is carry out in a single cylinder water cooled Di Diesel engine with Eddy current Dynamometer, Biodiesel produced from  Ultrasonic assisted transesterfication process and thermo-physical properties of biodiesel and their blends from both the process were analyzed. The test fuel were prepared in the ratio of SUB 25, SUB 50, SUB 75 and SUB 100, which represent the blend ratio of Sheep fat oil biodiesel and the rest diesel fuel. The investigational results reveal a marginal decrease in brake thermal efficiency when compared to that of sole fuel.  In this analysis, the emission test were conducted with the help of AVL Di gas analyzer, in which CO, HC and smoke density are marginal increased on the other hand and NOx are significantly reduced when compared to that of sole fuel. Cylinder pressure and H.R.R. were also performed with help of AVL Di Gas Analyzer.
