Analysis of the Pre-injection Configuration in a Marine Engine Through Several MCDM Techniques
(University of Zagreb Faculty of Mechanical Engineering and Naval Architecture, 2021)[Abstract] The present manuscript describes a computational model employed to characterize the performance and emissions of a commercial marine diesel engine. This model analyzes several pre-injection parameters, such as ... -
Analysis of the Pre-Injection System of a Marine Diesel Engine Through Multiple-Criteria Decision-Making and Artificial Neural Networks
(Mathematical Institute, Slovak Academy of Sciences, 2022-01-01)[Abstract] The present work proposes several pre-injection patterns to reduce nitrogen oxides in the Wärtsilä 6L 46 marine engine. A numerical model was carried out to characterise the emissions and consumption of the ... -
Effect of multiple injection strategies on emissions and performance in the Wärtsilä 6L 46 marine engine. A numerical approach
(Elsevier, 2019-01-01)[Abstract] The present paper proposes a Computational Fluid Dynamics model to analyze the operation cycle and exhaust gas composition in a four-stroke marine diesel engine, the Wärtsilä 6L 46. Once validated, the numerical ... -
Multi-criteria analysis to determine the most appropriate fuel composition in an ammonia/diesel oil dual fuel engine
(MDPI, 2023-03-24)[Abstract] The possibility to employ alternative fuels is gaining special interest in the marine sector. There are several suitable candidates for traditional fossil fuels substitution. Among them, ammonia is a promising ... -
Numerical Analysis of Emissions from Marine Engines Using Alternative Fuels
(Sciendo, 2015-12-30)[Abstract]: The current restrictions on emissions from marine engines, particularly sulphur oxides (SOx ), nitrogen oxides (NOx ) and carbon dioxide (CO2 ), are compelling the shipping industry to a change of tendency. In ... -
Possibilities of Ammonia as Both Fuel and NOᵪ Reductant in Marine Engines: A Numerical Study
(MDPI, 2022-01)[Abstract] Nowadays, the environmental impact of shipping constitutes an important challenge. In order to achieve climate neutrality as soon as possible, an important priority consists of progressing on the decarbonization ...
