Summary on Grant Application Form |
|
A wide range of catalyst simulations have been developed over the past decade, the vast majority of which are based on steady flow theory. As such, these models are used in isolation from engine simulation code. However, catalysts are subjected to highly pulsating and unsteady flow regimes when they are used in service and so existing catalyst models are incapable of predicting the true reaction rates under these conditions. A further limitation of steady flow models is that they cannot be combined with currently available engine simulation packages. This is a major disadvantage since it is known that catalytic converters create wave reflections which travel back towards the engine causing significant variations to engine performance. This in turn causes variations in the composition of the exhaust gas and therefore the reaction rates within the catalyst. Consequently, the true performance of both the engine and the catalyst can only be predicted when both are combined in the same one-dimensional simulation.The aim of this research is to develop and validate a three-way catalyst model based on unsteady flow theory. This model will then be linked to an existing onedimensional engine simulation package. The resulting combined model will then be validated against steady-state, transient and drive cycle measurements recorded from an automotive gasoline engine.
