Tighter emission standards, as well as requirements for increased emission system performance and durability, have resulted in continuing advances in emission control technology. This publication discusses the latest developments in this area. Contents include: analysis of catalyst durability data from the standpoint of substrate surface area; cycle-by-cycle analysis of HC emissions during cold start of gasoline engines; hot vibration durability of ceramic preconverters; fast light-off of underbody catalysts using exhaust gas ignition (EGI); EHC impact on extended hot soak periods; utilizing intake-air oxygen-enrichment technology to reduce cold-phase emissions; calculating the rate of exothermic energy release for catalytic converter efficiency monitoring; and more.
