A Review on performance of Hybrid of Thumba and waste vegetable oil

Mechanical Engineering

ABSTRACT The research activities from past two decades have been vigorously done in the area of alternate fuel for CI engine and still it is going on. The rapid industrialization and motorization aims a serious threat to the draining of petroleum resources, also developing countries consuming huge amount of energy by fossil fuels for their development that also affects on depletion of fossil fuels. Due to depletion of fossil fuel and environmental concern has promoted to look over the bio fuel as an alternative fuel source. Many investigations and studies revealed that the oils from the vegetable origin can be successfully implemented to the existing CI engines without any major hardware modification and still further research is necessary to find a fuel resource from a waste recovery point of view. In this regard, generally biodiesel has obtained from vegetable oil and animal fat that have been considered as a promising alternate fuel. The research regarding blends of Diesel and single biodiesel have done already. Very few works have been done with combination of two different biodiesel blends with diesel (i.e. Hybrid fuel) and left a lot of scope in this area. Therefore waste cooking oil and thumba can be used as a potential alternative fuel. This paper reviews the production, potential, characterization, and engine performance of the waste cooking oil and thumba biodiesel through the experimental work carried out in various part of the world.
