Abstract: This research aims to optimize the performance and emissions of a dual-fuel marine engine by a flexible valve train approach. A mathematical model for the flexible valve train strategy including its two sub-mechanisms (Flexible Camshaft Technology (FCT) and Multi-segment Camshaft) is developed in MATLAB. After that, a phenomenological combustion model based on fractal combustion principle is developed in AVL CRUISE-M. The combustion model includes many sub-models and allows the valve timing positions to be imported to investigate their influence on the engine performance and emissions.
