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.
