Abstract

This comprehensive review examines biodiesel as a viable substitute for conventional diesel fuel in internal combustion engines, highlighting its environmental benefits such as reduced emissions. Despite these advantages, the review acknowledges technical challenges and environmental concerns. It discusses advancements in biodiesel production, especially the one-step transesterification process, and explores the efficiency and emissions profiles of various biodiesel blends in generator engines. The review analyzes the effects of injection timing (IT) and nozzle geometry on biodiesel spray characteristics, with a focus on diesel engines equipped with common rail direct injection systems. It investigates the influence of nozzle geometry, injection pressure, and bowl geometry on engine emissions and performance, emphasizing the role of IT and pressure in regulating engine behavior. While recognizing biodiesel’s potential as a renewable and biodegradable alternative, the review stresses the need for ongoing research to overcome technical limitations and address environmental concerns, aiming to fully realize biodiesel’s potential as a sustainable energy source.
