BIODIESEL PRODUCTION THROUGH ULTRASONIC CAVITATION PROCESS AND PERFORMANCE TESTING

Abstract

Fuel crisis because of dramatic increase in vehicular population and environmental concerns have renewed interest of scientific community to look for alternative fuels of bioorigin such as vegetable oils. In this project biodiesel has been produced through various methods and its performance testing is done in C.I. engine. For this project biodiesel sample has been prepared by ultrasonic cavitation, hydrodynamic cavitation and magnetic stirrer method and comparison has been made between ultrasonic cavitation and magnetic stirrer method. For this project biodiesel has been prepared by three different oils namely jatropha oil, thumba oil and waste cooking oil and comparison also has been made between different oils. The performances of this biodiesels have been checked by the performance parameters like torque, brake power, brake thermal efficiency and specific fuel consumption and emission characteristics by opacity. Performance testing has been performed in 4-stroke, 4- cyli...
