Modeling and Evaluation of Oxy-Combustion and In Situ Oxygen Production in a Two-Stroke Marine Engine

Considering the concerns for emissions reduction in maritime sector, present paper evaluates, through modeling and simulation, oxy-fuel combustion a two-stroke ship engine (2SE) best production system configuration to obtain required oxygen (O2). An initial model of is calibrated with manufacturer’s data then adapted work O2 as oxidant eliminate nitrogen oxide (NOx) exhaust gas recirculation (EGR) control in-cylinder temperature. Mixed Ionic–Electronic Conducting (MIEC) membranes produce necessary from ambient air, which heated up pressurized by heat exchanger turbocharging coupled provide air conditions proper operation MIEC. Several layouts this are evaluated full load operating point find optimum configuration. Results reveal that under avoids NOx at expense higher brake-specific fuel consumption (BSFC) original brake torque, also expels stream composed exclusively CO2 H2O, facilitates separation gases.
