Integrated HFO Modeling and RSM-Based Synergistic Optimization of Combustion-Emission Performance for Marine Low-Speed Diesel Engines.

ABSTRACT: Low-speed, two-stroke marine diesel engines are facing more severe challenges regarding nitrogen oxide (NOx) emission control and fuel economy with the increasingly stringent global emission regulations and the implementation of carbon tax policy. Based on the fixed-speed cruise operating condition data recorded in the engine log of a real ship, a marine heavy fuel oil (HFO) model was innovatively established in this study, as well as a simulation model of the engine operation on a real ship. By comprehensively evaluating the interaction between scavenge air and fuel injection parameters, a multiparameter synergistic optimization strategy was proposed to systematically reveal the mechanism of key operating parameters on the engine's combustion performance and emission characteristics.
