Development of a zero-dimensional model and application on a medium-speed marine four-stoke diesel engine

The present study deals with the development of a zero-dimensional model for marine diesel engines of the four-stroke type, as well as a methodology to automate its calibration process. The modelling and calibration approach is validated using experimental and operational data from a Wärtsilä engine, covering several model input and outputs. Validation results suggest that the modelling approach suggested, can predict the stationary and transient responses of the engine within 3.5% on measurements taken during the vessel's operation for a variety of loads ranging between 20% to 100%, with minimal calibration effort from the modeller
