Performance and Combustion Characteristics of Rice Bran Methyl Ester oil With Different Combustion Chambers by Varying Injection Pressure

摘要

Biodiesel crops such as Jatropha and Pongamia are being grown exclusively for biodiesel production. An alternative approach is to grow a food crop and use the waste material for biodiesel. Crude rice bran oil (RBO) is unpurified non-edible vegetable oil, which is available in huge quantities in rice enlightening countries the research in this area to utilize as a replacement for mineral Diesel in not much. Crude rice bran was obtained from solvent extraction process by using n-hexane. Presence of long carbon linear chain gives excellent solubility in diesel. The calorific value (CV) of RBMEO is high and is closer to diesel. The corrosiveness of it also very mild due to nature of phenolic compounds present in it. Higher viscosity is the only drawback of every vegetable oil and this can be lowered while blending with diesel and ethanol if necessary. From these studies, the RBMEO biodiesel have the properties much closer to the conventional diesel and which can be used as a biodiesel in addition with diesel fuel. The goal of this study is to bring the alternative usage of RBMEO biodiesel to the limelight and to mitigate the serious problems posed by the depleting petroleum reserves. This work precedes the RBMEO (B100) biodiesel performance by different combustion chambers like hemisphere (base), toroidal and shallow depth shape pistons, comparison with petroleum diesel processes at constant speed and by varying injection pressure from 180-240bar with the intervals of 20bar, as well as environmental impact and controls of the liquid as petrochemical feedstock.
