The key technical aspects of a catalyzed particulate filter (CPF) system development are software calibration for regeneration and component optimization for system performance. It is important that the optimized component specification be selected an early stage since the components have an effect on the overall regeneration strategy. Accordingly, in a catalyzed particulate filter system the washcoat and precious metal loading are main components that should be optimized at an early stage of the system development. An accelerated aging protocol is needed in order to properly evaluate the performance of various catalyst systems in a timely manner.
