Engine Calculations

This was also university assignment on the subject of internal combustion engines and ecology, the task given to me was to perform all of the thermodynamic calculations as well as calculate the mechanics of a 69 kW diesel engine. Unfortunately I have the projects only written in Macedonian language and I am working on having it translated, but for now I will just upload the Macedonian version of it and some screenshots from the diagrams I got. The diagrams were created using Matlab.
