Analysis of the Pre-Injection System of a Marine Diesel Engine Through Multiple-Criteria Decision-Making and Artificial Neural Networks
Rodríguez, C.G.; Lamas, M.I.; Rodríguez-García, JuanDeDios; Abbas, A. (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 ... -
Hydrodynamics of Biomimetic Marine Propulsion and Trends in Computational Simulations
Lamas, M.I.; Rodríguez, C.G. (MDPI, 2020-06)[Abstract] The aim of the present paper is to provide the state of the works in the field of hydrodynamics and computational simulations to analyze biomimetic marine propulsors. Over the last years, many researchers ... -
NOₓ Reduction in Diesel-Hydrogen Engines Using Different Strategies of Ammonia Injection
Lamas, M.I.; Rodríguez, C.G. (MDPI, 2019-04)[Abstract] In order to reduce NOₓ emissions in internal combustion engines, the present work analyzes a measurement which consists of injecting ammonia directly into the combustion chamber. A commercial compression ignition ... -
Numerical Analysis of Emissions from Marine Engines Using Alternative Fuels
Lamas, M.I.; Rodríguez, C.G.; Rodríguez-García, JuanDeDios; Telmo Miranda, Javier (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 ... -
Numerical Analysis of NOₓ Reduction Using Ammonia Injection and Comparison With Water Injection
Lamas, M.I.; Castro-Santos, Laura; Rodríguez, C.G. (MDPI, 2020)[Abstract] This work analyzes NOₓ reduction in a marine diesel engine using ammonia injection directly into the cylinder and compares this procedure with water injection. A numerical model based on the so-called inert ... -
Numerical Model of SO2 Scrubbing with Seawater Applied to Marine Engines
Lamas, M.I.; Rodríguez, C.G.; Rodríguez-García, JuanDeDios; Telmo Miranda, Javier (Sciendo, 2016-06-30)[Abstract]: The present paper proposes a CFD model to study sulphur dioxide (SO2) absorption in seawater. The focus is on the treatment of marine diesel engine exhaust gas. Both seawater and distilled water were compared ...
