Abstract
With the increase in pollution due to burning fossil fuels and soaring prices of fossil has compelled us to adopt alternative fuels which are environment friendly in nature as well as cheap to the pockets of the consumers. Biodiesel, a type of diesel fuel made of long-chain fatty acid esters produced from plants or animals, is one of the acceptable substitutes. When using biodiesel fuel in automobiles, it is blended with regular diesel fuel. Biodiesel reduces the formation of pollutants such as particulate matter, soot but it contributes to rise in nitrogen oxides (NOx) emissions as a result of a surge in combustion chamber temperature. Increase in NOx concentration causes breathing problem, cancer and ultimately lead to death. The area of research here includes the proposed system of exhaust gas recirculation to reduce NOx emissions from biodiesel fuel.
