Abstract:
In this research jatrophacurcas have been used to extract oil and convert it to bio-fuel by adding 50 ml of methanol and 3 mg of sodium hydroxide.
Four different samples of fuel were prepared by blending jatropha bio-fuelwith diesel fuel by four different ratios (10BJ90, 20BJ80D, 30BJ70D and 50BJ50D).
Experiments were conducted on four cylinders, four stroke, compression ignition engine, at five different speeds and five different fuel samples (diesel fuel and the other four blends).
According to the results obtained it was found that the blend 30BJ70D gives the highest brake power at engine speed of 2000 rpm and lowest brake specific fuel consumption at speed of 1500 rpm, as for the blend 50BJ50D it gives lowest CO and SO2 emissions level for all engine speeds.
