These by-products are generally used as fish freed after being dried. In this study, crude fishing oil is applied to be raw material for biodiesel production. The biodiesel which is alternative fuel for engines or boilers can reduce impact of environmental pollution from fossil fuel. The biodiesel produced from the current process was tested its fuel properties and engine performance. The experimental results show that the biodiesel of crude fishing oil appeared to have larger heating values, cetane index, carbon residue and black smoke opacity while lower flash point in comparison with those of biodiesel from soybean oil. In the aspect of engine performance, biodiesel of crude fishing oil shows to have lower fuel consumption rate and higher brake fuel conversion efficiency. However, the brake fuel conversion efficiency of the super low sulfur diesel appeared to increase and larger than that of the biodiesel when the engine speed increased. The effects of antioxidant on oxidative stability of the biodiesel where studied as well. The biodiesel added with antioxidant has larger methyl ester content while lower acid number, kinematic viscosity and carbon residue. Keyword : Biodiesel, Crude fish oil
