Transportation is important for day-to-day operations and economic development. Transportation of different modes, power generation, agriculture, mining locomotives, and all of them are dependent on fossil fuels. Over the last six decades, crude oil use has risen 16-fold. The need for and use of petroleum-derived fuel is growing day by day, but there is scarcity. Biodiesel in place of fossil fuels will meet the current demand for gasoline. Biodiesel can be derived from both traditional and non-conventional sources with some modifications in order to meet the performance of diesel. The emission of CI engines causes adverse environmental impacts such as green-house gases, acid rain, ozone depletion, photochemical smog, etc. Biodiesel is the perfect replacement for fossil fuels. It can be prepared from vegetable oil and animal fats by the transestesterification process. National biofuel policy 2009 set the goal of meeting 20% of diesel demand with biodiesel. India is planning to mix 5% biodiesel with diesel." India has focused primarily on Jatropha. There are, however, around 400 species of non-edible oil seeds bearing trees in our country, where thrust must be made derived the biofuel. Based on the techno-economic viability for the development of biofuels in this paper thrust are made to review a different kind of biofuel utility and their impact on CI engine efficiency that explorer in the last decades.

In this paper, palm olein oil was used to produce biodiesel by reducing the percentage of free fatty acids in the oil and then performing a transesterification reaction. biodiesel is one of the sources of alternative fuels. Palm olein oil had treated with sulfuric acid as a catalyst at a ratio of 0.25 wt%. The reaction took place at a methanol-to-oil molar ratio of 3:1 at a temperature of 60 °C and stirred to 250 rpm and for 60 minutes after that, the methanol had separated from the oil. This process reduced the free fatty acid plant by 5%. The transesterification reaction was done by placing 50g of palm olein oil and the reaction had carried out with a methanol-to-oil molar ratio of 6:1, and the catalyst was 1wt%, where the reaction occurred at a temperature of 60 °C for 120 minutes and stirred at 300 rpm. The results of the produced 44.87g of biodiesel and12.34g of glycerin. Test showed an increase in dynamic viscosity, higher biodiesel density, lower calorific value, higher flashpoint, and a higher cetane number compared to fossil diesel. [ABSTRACT FROM AUTHOR]

Due to the limited availability of crude oil many countries across the world, moving towards alternative fuels derived from renewable sources and bio-fuels from vegetable, plants, animals and aquatic animal's fat or oil etc, are used to increase the energy for transportation system and to reduce the pollution impact on the countries environment. In order to reduce the demand and dependency of crude oil, bio-fuels are the best alternative for petroleum. Some bio-fuels are derived from edible oil which makes the negative impact on food chain causes the early depletion. In this context, review shows the use of easily available, non-edible, oil rich Michelia Champaca seeds are used for the production of biofuel and bio-lubricant for I C Engine. [ABSTRACT FROM AUTHOR]
