The investigation of the effects of washing process on biodiesel production to fuel properties and engine performance
The major part of all energy consumed worldwide comes from fossil sources (petroleum, coal and natural gas). The search for alternative fuels, which promise a harmonious correlation with sustainable development, energy conservation, efficiency and environmental preservation, has become highly pronounced in the present context. One of the more promising approaches is the conversion of vegetable oils (VOs) and other feed stocks, which primarily contain triglycerides (TGs) and free fatty acids (FFAs), into biodiesel. Injection, atomization and combustion characteristics of vegetable oils are very different from those of diesel fuel. Experiments were made on single-cylinder, four-stroke, water-cooled, direct injection diesel engine. Crude biodiesel was produced utilizing refined cottonseed oil through the transesterification method. Crude biodiesel was subjected to wash with pure water (distilled water DW) and deionized water (DEW). At the end of this process biodiesel is obtained. The effect of the specifications of diesel fuel with these produced-biodiesels on engine performance has been observed. Result of the experiments prove that COME (DEW)fuel obtained by being washed with deionized water gives better performances than COME (DW) fuel obtained by being washed with distilled water on engine torque, effective power and specific fuel consumption respectively at the values as following %0.8, %0.75 and %0.81. © Sila Science.
