An Alternative Diesel Fuel Extracted from Strained Draff of Sunflower Oil (Part 1)

Fuel Extraction and Engine Performance

Abstract

To utilize the strained draff of sunflower seed oil (seed draff), the sunflower oil remaining in seed draff was extracted with kerosene. The extracted oil was used as a diesel fuel. The strained draff of the extracted oil (exracted draff) was also processed to solid fuel by mixing with wood chips.
To obtain an extracted oil with the the same viscosity as No. 2 diesel oil, the mixing ratio was 0.5g kerosene to 1cm³ seed draff. About 73% of the sunflower oil remaining in seed draff could be extracted with kerosene. The output performance with the extracted oil was similar to the No. 2 diesel oil. The cold startability with extracted oil was excellent, and there was no wear of the injection pump. A small amount of white deposit accumulated around the injection nozzle port during idling.
