Research Paper: Role of Biodiesel in IC Engines and Its Impact on Performance, Combustion, Emissions, and Tribology

Abstract

The world is facing a critical energy crisis due to increasing fossil fuel consumption and its consequent environmental impacts. In India, the dependency on petroleum imports for energy needs has spurred the demand for alternative fuels, especially biofuels. This paper provides an in-depth analysis of the scenario of feedstock for biofuel production in India, with a focus on biodiesel. Biodiesel, derived from renewable sources such as plant oils, animal fats, and recycled greases, has gained attention due to its potential to reduce greenhouse gas emissions and improve energy security. The research explores various types of feedstocks, methods of biofuel production, blending techniques, and the properties that influence biodiesel's performance in internal combustion (IC) engines. The paper further delves into the role of biodiesel in improving engine performance, combustion efficiency, emissions, engine wear, and tribological impacts. Finally, the study highlights the need for engine modifications for biodiesel utilization and the future scope of biodiesel in the Indian energy landscape.
