Abstract

The article presents an algorithm for creating software leading to the optimization of the combustion process of marine engines. Parameters determining the Existing Ships Energy Efficiency Index (EEXI) related to ship type, capacity, and propulsion principle are considered. Test data on the characteristics of a two-stroke main engine, model HYUNDAI 6S60MC-C for six types of loads were used as the basis. To present the working field of the engine, the necessary calculations have been carried out and dependencies have been derived for the power and the specific fuel consumption as a function of the revolutions. The implementation includes the development of a small software program using Delaunay's triangulation algorithm to create 3D graphics, as well as Python libraries and methods.
