Experimental Investigation of I.C Engine using various Diesel Blends

Abstract

The diesel fuel used in engines for power generation in various industrial applications produce high exhaust pollutants because of poor engine performance. It has become a need to reduce these pollutants by using suitable additives along with diesel and improve the engine performance. The present research work focuses at improving the engine performance by using selected blending agents of linseed oil and watermelon seed oil, having low contaminants in the emission. The performance study of a diesel engine with these diesel blends were carried out at different compression ratios and loads using five chosen samples. The combustion performance parameters like Mechanical, Volumetric, Brake thermal efficiencies and Specific Fuel Consumption are studied. The fuel sample blends containing 90% Diesel has shown better combustion performance compared with diesel at high compression ratio. The Specific fuel consumption for the blend containing watermelon seed oil and ethanol (5% each by volume) is lesser than diesel at all compression ratios. The Brake thermal efficiency for the blend containing linseed oil and leishman's solution (5% each by volume) is higher at compression ratios 17 and 17.5.
