Development and application of a computer aided engineering methodology supporting the design optimization of automotive exhaust treatment systems
Abstract
Chapter 1 presents a short review of legislation, recent advances in engine and catalytic converter technology, testing and modeling approaches, aiming at the better comprehension of the objective of this thesis and the effort exerted at all fields of vehicle engineering. Chapter 2 presents the catalytic converter simulation model, primarily focused on (a) the improvements made in the core and the shell of the source code and (b) the systematic approach towards the minimization of the model’s tunable parameters. The principles of the optimization algorithm that was used are also presented in this chapter, as well as the development of user friendly GUIs, towards the transformation of this kind of mathematical models into robust CAE tools. Chapter 3 presents the quality assurance methodology of experimental data that was developed in the frame of this thesis. Quality assurance procedures were first applied to the catalytic converter inlet test data, which are prerequisite as input for t ...
