Investigation of the Effects of Linseed Oil Biodiesel and Diesel Fuel Blends on Engine Performance and Exhaust Emissions

Abstract

In this study, linseed oil was obtained with the aid of screw presses and linseed oil biodiesel (B100) (linseed oil methyl ester) production was performed by transesterification method. Linseed biodiesel was blended with regular diesel fuel at different ratios as B2 (98% diesel + 2% biodiesel), B5 (95% diesel + 5% biodiesel), B20 (80% diesel + 20% biodiesel), B50 (50% diesel + 50% biodiesel). Fuel properties tests were performed on all fuels. Results revealed that engine performance values of linseed biodiesel and fuel blends were similar with the standard diesel fuel. With regard to maximum torque, while the highest value was obtained as about 59.6 Nm at 1000 rpm with diesel fuel, the value was observed as about 53.8 Nm at 1200 1/min with B100 fuels. The highest maximum power output was recorded as approximately 10.96 kW at 2100 rpm with diesel fuel and as approximately 10.23 kW at 2000 rpm with B100 fuels. With regard to minimum specific fuel consumption, while the lowest value was measured as about 231.36 g/kWh at 1000 rpm with diesel fuel, the value was measured as about 296.73 g/kWh at 1200 rpm with B100 fuels. Exhaust emissions are generally improved by the addition of linseed biodiesel to diesel fuel.
