The Method of Energy-Efficiency Investigations of the Newly Produced Marine Fuels Through an Application of the Laboratory Diesel Engine

Abstract The article deals with one of the scientific issue solved within frames of the research project financed by Voivodeship Fund for Environmental Protection and Water Management in Gdansk, namely, in particular, the method of energy investigations of the self-ignition engine in conditions of its supply with a non-standard (modified) marine fuel. The representative results of engine tests worked out on the especially built laboratory test bed have been presented. They aimed to elaborate energy profiles of a single-cylinder four-stroke Diesel engine in the form of Sankey diagrams of energy flows representing the most efficient and effective manner for the verification of a different kind of the modified marine fuels introduced on market. It is expected that the final results of the project will be interesting for their producers as well as the ship-owners of the operated ships, and also for the offices of sea administration as well as the inspectorates of environment protection.
