A Methanol Fueled Marine Engine Simulator for Fast Craft Application
Description
The paper presents a thermodynamic simulator of a marine four-stroke
medium speed engine, fueled by methanol. The study stems from the current lack of
information on methanol marine engines, whereas there is a growing interest in this
type of alternative fuel, also in the maritime field. The numerical model, developed
in Matlab©-Simulink© language and structured in a modular form, is derived from
a natural gas marine engine simulator, developed by the authors and already
described and validated in a previous research study. In the methanol engine model,
for the in cylinder phenomena calculation, the zero dimensional actual cycle
approach is adopted, while the turbocharger compressor and turbine are simulated
by their performance maps. After a short description of the original natural gas
simulator, the paper reports the variations introduced for adapting the engine model
to the methanol fuel mode. The obtained outcomes are compared with data referring
to a dual fuel natural gas engine, available in the literature. This comparison,
between the simulated results of the two fuel modes of the engine, aims at
highlighting the differences in efficiency and carbon dioxide emissions, in order to
improve the environmental impact of the medium and high-speed vessels.
