Engine Dynamometers for the Testing of Catalytic Converter Durability

This paper explains many factors of accelerated catalyst life testing. The testing is done with many objectives, one of which is catalyst screening.

Dynamometer testing schedules are explained throughout and show they are useful tools for catalyst screening (ranking) and for studying durability characteristics of materials for a given type of fuel. Certain correlations are shown in order to demonstrate the fact that the results from these dynamometer test schedules are indeed meaningful.

Results indicate that the emissions measured compared well with the Federal Drivability schedule.
