Biodiesel, derived from the transesterification of vegetable oils or animal fats, is composed of saturated and unsaturated long-chain fatty acid alkyl esters. In spite of having some application problems, recently it is being considered as one of the most promising alternative fuels in internal combustion engine. The aim of the present paper is to do a comprehensive review of engine performance and emissions using biodiesel from different feedstock and to compare that with the diesel. From the review it is found that the use of biodiesel leads to the substantial reduction in PM, HC and CO emissions accompanying with the imperceptible power loss, the increase in fuel consumption and the increase in NOx emission on conventional diesel engine with no or fewer modification. However, many further researches about modification on engine, low temperature performance of engine, new instrumentation and methodology for measurements, etc., are recommended while using biodiesel as a substitute of diesel.

The increasing demand of petroleum based fuel is because of rapid and fast industrialization of automotive sector. There are limited reserves for petroleum based fuels. These are available in limited amount in the world. Therefore the countries those are not having the sufficient stock of petroleum based fuel, are facing the problems of increase cost of fuel which mainly due to the cost involved in the import of the petroleum based fuel. Hence it is required to developed out and investigate the other resources of the alternative fuels, which can be produced easily and locally available sources such as Alcohol, Biodiesel, Vegetable oil, seed oil etc. Methyl or ethyl esters of fatty acids produced from vegetable oil or an animal fat is called biodiesel. Non edible oil or animal fats are the main recourses for production of biodiesel such as Jatropha, Palm, Marine fish oil, Soybean, Cottonseed etc. Biodiesel blends are prepared in a variable proportion with diesel to use in a conventional diesel engine. By using biodiesel in an engine there is also profitable in the reducing harmful pollutants in the environment. This paper reviews the production, properties, performance and emission analysis of different feedstock of blends of biodiesel and experimental work carried out in the various parts of the world. The objective of this study is to produce biodiesel from Jatropha oil, test its properties, and compare its properties with that of diesel. Due to the petroleum shortage the researchers take interest in finding the alternative fuels for internal combustion engine. There are various types of alternative fuels available for internal combustion engine but biodiesel is most important alternative to diesel engine. Biodiesel is popular due to its renewability, lower exhaust emissions, and biodegradability . Most of the researchers have defined transesterification is one of the
