C5 - Understanding and modeling the influence of real operation conditions on catalyst performance

Objective

The objective of project C5 is an improved understanding of the relation of catalyst structure and activity for cleaning exhaust gases in transient real engine operation. Both the understanding of the structure-activity relation and the very dynamic operation of a real engine demand time- and space resolved emission measurements enabling cycle resolved emission analysis as well as time and space resolved numerical simulation of the emission control devices. Experimental and simulation data will be compared evaluating the performance of the developed materials and models. In this way, this project closes the loop between the microscopic, mesoscopic, macroscopic and technical level of the CRC.
