Biodiesel as an Alternative Fuel: A Review

Abstract

The global transport directly or indirectly depends upon petroleum and its product. As per the consumption, these petroleum products will be extinct within the upcoming 100 years. This review paper focuses on the change and prospects of the vegetable oil and their substitutes. Using different additives of diesel fuel with the biodiesel oil of a 4 stroke diesel engine for evaluating the performance, combustion, and emission characteristics. This is a review of experimental study in which biodiesel blends by volume (5, 10, 15, and 20%) and its denotation B5D, B10D, B15D AND B20D, respectively. The testing of such fuel shows that the viscosity and density of the blended kerosene fuel reduced as compared to the original fuel. There is a reduction in lubrication and wear problem.
