PROPERTIES OF VEGETABLE OILS AND THEIR INFLUENCE ON PERFORMANCE AND EXHAUST EMISSIONS OF A DI-DIESEL ENGINE ? A REVIEW

Straight vegetable oil (SVO) as an alternative fuel in engines is a statement of controversy since many years as SVO has conflicting results in emissions, performance of engines. Many factors are involved in evaluating the emissions and performance characteristics of engines running on SVO. This paper presents a review on studies published regarding SVO’s with a focus on the physical and chemical properties and emission characteristics on different types of Diesel engines. A review is made considering different types of SVO’s such as Jatropha, Karanja, Cottonseed, Tobacco seed, Karanja, Mahua, Rubber seed, Soap nut, Deccan hemp, Palm, Soya bean and Neem oils.
