Enhancing marine diesel engine compatibility with sustainable fuels: Key factors and adjustments.

This work explores biodiesel as an environmentally sustainable alternative fuel for marine diesel engines, aiming to reduce air pollution and dependence on traditional fuels. The analysis covers biodiesel's historical background, impact on engine performance, recent advancements, concerns about warranties, challenges, and potential solutions, particularly in maritime applications. The work underscores biodiesel's potential in the marine sector for reducing harmful gas emissions but acknowledges challenges like increased brake-specific fuel consumption (BSFC) and nitrogen oxide emissions. Many marine engine manufacturers offer conditional warranties for biodiesel engines, emphasizing the need for appropriate modifications and maintenance practices. Examining compatibility factors such as engine design, fuel injection systems, combustion chamber design, materials compatibility, and ignition systems, the study stresses the importance of comprehensive engine testing, calibration, and ongoing monitoring for peak performance and emissions control. This condensed report enhances our understanding of the benefits and challenges of adopting biodiesel as a sustainable fuel in the maritime sector.
