Performance of a diesel engine using sudanese peanut oil as a fuel

الملخص EN

The world has recently faced fossil fuel depletion and environmental degradation that triggers the research for using alternative modes.

Bio-fuels appear to be one of the most reliable and recommended ones.

Sudan potentiality of producing bio- fuels is highly promising and can be quite feasible since enough fertile land, water and suitable climate are available.

In this paper production of sudanese peanut oil methanol ester was attempted and tested in a 4-stroke diesel engine for performance evaluation and compared with fossil fuel.

Using transesterification process at volumetric ratio of 40oil: 12methanol: 1 NaOH, a temperature of 60 0c and stirring for one hour time, produced a bio-diesel of better properties as an acceptable substitute for conventional diesel fuel.

Without any need for engine systems modifications, engine performance was improved and exhaust emissions were highly reduced.
