An Experimental Investigation on Four Stroke CI Engine with Diesel and Bio-Diesel Blend as fuel: Hazelnut

Abstract

An experimental investigation was carried out to analyze non-edible oils (hazelnut) in blending with normal diesel fuel with approximate proportions of 5%, 10 % , 15%, 20% and 25% by volume in a mono cylinder, four stroke vertical, water cooled, Compression Ignition engine. Experimentation was performed by using the above fuel blends in the compression ignition engine operating at different loads. A comparative analysis was made on the output parameters such as emissions like oxides of nitrogen(NOx), total unburned hydro carbons, oxides of carbon(COx), and partially burned hydro carbons, Brake specific fuel consumption, Brake Thermal Efficiency, smoke density, temperature of exhaust gases, for all blends prepared with bio-fuels mixing with normal diesel fuel at different proportions mentioned above. It was known that engine is giving better performance by using a blend B20 with proportions of 20% hazelnut bio-fuel and 80% conventional diesel fuel without any modifying in design parameters and operating characteristics of the engine. Engine working on bio-diesels blend as fuel are showing considerable reduction in emissions like oxides of carbon and hydro carbons but with marginal increase in oxides of nitrogen without effecting brake thermal efficiency when compared with conventional neat diesel fuel. The corresponding neat diesel fuel operation, the bio-fuel oil blends show decrease in emissions of smoke with marginal increase in NOx with unchanged brake thermal efficiency. Hazelnut bio-diesel having better properties next to diesel fuel in comparison with other bio fuels
