 Green diesel fuel is a type of biodiesel that can be used in diesel engines. It has improved lubricity compared to traditional diesel fuel, which reduces engine wear and improves performance. Additionally, green diesel fuel can be composed of various components, including hydro-treated diesel fuel, bio-additives, and other components. This allows for greater flexibility in terms of producing the desired fuel quality. Furthermore, the optimal composition of green diesel fuel with improved lubricity has been determined, allowing for more precise control over the fuel's properties. Finally, a mathematical equation has been developed to describe how the addition of anti-wear additives affects the wear-scar diameter of the fuel. This article was authored by Anselika M.
