Tiivistelmä
The aim of the work was to provide an overview of the fuel supply system of the 32LG internal combustion engine. The work presents the function of the different modules in the fuel supply system, engine-related calculation, and the internal mass balances of the system. Additionally, the work discusses how different fuel properties affect the system design and requirements.
A steady-state simulation file was created to evaluate the existing design. The results presented in the thesis mainly focus on the suitability of the pipe sizes and the estimation of unknown mass flows within the system. Furthermore, an optional design for the cooling of the recirculated fuel was presented. However, to evaluate the design, further measurements and data are needed. The simulation file was constructed so that the operational parameters may be modified, and the file can be used to test different scenarios in the future.
The research has mainly been done by discussions with colleagues and by literature studies. Digital testing in the simulation software Aspen HYSYS has also been the basis for many of the topics presented in the thesis.
