Durability of Light Duty Diesel and Gasoline Emission Control Systems
One of the most important aspects of meeting emission standards is catalyst robustness. Emissions must be met at high mileage, termed “full useful life”, which is 150,000 mi for light and medium duty vehicles under Tier3/LEV3. Catalyst durability is application and system specific. Full useful life aging and correlations to accelerated aging schemes typically include both hydrothermal exposure and chemical poisoning. Robustness tests are designed to exceed the limits of a particular catalyst or filter material and test to failure. New aging schemes and robustness tests are needed when new technologies such as cold start traps for HC and NOx, gasoline particle filters, and SCR coated filters are incorporated into conventional three-way and diesel exhaust systems. This presentation will include a summary of recent emission certifications and publications by various vehicle manufacturers, aging and robustness testing of conventional exhaust systems, as well as a look into the durability of future emission control technologies.
