- Summary:
- The aim of this paper was to describe a method of accelerated three way catalyst (TWC) aging performed on a test bed for OBDII monitoring purposes and screening of different catalyst solutions. To accelerate the catalyst aging process, the exhaust gas temperature was elevated to a range above 1150°C, which is typical for an aging cycle performed using ovens. Catalyst emissions performance was checked at new condition (after degreening) and subsequently at predefined intervals, based on the oxygen storage capacity (OSC) evaluation. The emission tests were performed in the laboratory on the chassis dynamometer using legislation cycles. The accelerated aging method was found to be of use for verifying the EOBD functionality under vehicle operation with a degraded catalyst substrate. Secondly, the described method allows execution of a time-efficient aging cycle on a test bed in order to validate catalyst chemistry and lifetime and also to compare various catalyst samples with competitive technologies
