EFFECT OF JATROPHA METHYL ESTER ON DIESEL ENGINE- A REVIEW

The world is being modernized and industrialized day by day. As a result vehicles and engines are increasing. But energy sources used in these engines are limited and decreasing gradually. The rapidly depleting conventional petroleum resources have promoted research for alternative fuels for diesel engines. There is an urgent need for suitable alternative fuels for use in diesel engines. Vegetable oil is a promising alternative because it has several advantages; it is renewable, environmentally friendly. But major disadvantage of vegetable oil is its viscosity, which is higher than that of mineral diesel. Hence neat vegetable oil does not give better performance. In the present paper transesterified jatropha oil and its blend with diesel has been introduced as an alternative fuel to overcome the above problems. The literature results suggest that transesterified jatropha oil can be used as a substitute for diesel fuel without any significant modification in engine.
