Engine performance, combustion and emission studies of calcined chicken eggshell catalyzed marine fish waste oil biodiesel and their blends.

The current research is primarily oriented on determining the influence of marine fish waste (MFW) oil biodiesel catalyzed with calcined eggshell heterogeneous base catalyst (ESBD) and its blends on two-cylinder four-stroke diesel engine. The physicochemical and fuel properties such as free fatty acid content (0-0.25%), acid value (0-0.
