Abstract

The present study investigates the use of  hydro treated vegetable  oil  as  fuel  and   analyzes the  emission and performance characteristics of the Direct Injection 4 – stroke Diesel engine, air-cooled single cylinder, 4.4 kW, constant speed of 1500 rpm, and compression ratio 17.5:1.  The Refined Palmolein oil was hydrotreated using Ni-Mo as catalyst at 60 bar and 360°C. The hydrotreated refined palmolein oil was used as a fuel and compared with the transesterified fatty acid methyl esters. The properties of petro diesel, FAME, and hydro treated refined palmolein oil were compared with Euro IV Indian standards. The experiments were conducted systematically by blending the hydro treated refined palmolein oil by 25% (B25) and 100% (B100) by volume and at different loads such as 0%, 25%, 50%, 75%, and 100%.  The emission (CO, HC, NOx, and FSN), performance (BSFC and Brake thermal efficiency) combustion analysis were   measured.  The experimental results showed that there was   abatement in CO, HC, NOx, and BSFC while there was increase in brake thermal efficiency when compared with petro diesel fuel. The combustion pressure and heat release rate for B100 were almost equal to the diesel. No modification was required in the diesel engine.
