Abstract

Turbocharged diesel engines are complex engineering systems, which have a wide range of applications. Numerical simulations of the engine system for its performance, fuel economy and emissions offer affordable possibilities to improve the engine system itself and, furthermore, to optimize a larger system, such as a power plant and a marine propulsion system. As the simulation models of the diesel engines are used in a wide range of contexts, a library-based modelling approach provides benefits of making a modelling process and maintenance of the existing models easier. The model library should not be just a catalogue of the models but has to provide a solid model structure on different levels of abstraction and, therefore, guide the modeller to make appropriate decisions in a step-by-step manner at each level. Such a model structure consists of a technical component level, a physical concept level and a mathematical level. In this paper, application of the model structure to build a library for modelling turbocharged diesel engines is presented. For each level, a general framework is explained with practical examples. Finally, a procedure for building an engine system simulation model is demonstrated using a specific diesel engine model.
