Influence of Butanol and Nano Titanium Oxide into Non Edible Cotton Seed Oil Biodiesel on the Performance of CI Engine 2020-01-2134

Nonedible oil biodiesels and alcohols are the available renewable resources (liquid fuels) to reduce the dependency of diesel to fuel compression ignition engine. This experimental investigation is to study the performance of compression ignition engine fueled with blends of non-edible cottonseed oil biodiesel and butanol with the assistance of nano Titanium oxide in various proportions. Initially, a solubility and property testing of various proportions of biodiesel and butanol were performed to obtain an optimal blend possessing similar properties in comparison to that of diesel. This optimal blend was ultrasonicated with nano titanium oxide (0-100ppm). The addition of titanium oxide nano into biodiesel butanol blends was attractive and it improved the essential properties. Results of the property testing showed that 35% butanol can be blended with biodiesel to obtain blend possessing similar properties in comparison to that of diesel. In-cylinder peak pressure and thermal efficiency produced by the biodiesel butanol blend containing 50 ppm of nano titanium oxide were found higher in comparison to that of diesel. Emissions of oxides of nitrogen, smoke, carbon monoxide and hydrocarbon produced by this blend were also found significantly lower compared to that of diesel. This was due to the inclusion of nano titanium oxide into the blend.
