The following table illustrates the changes in emissions requirements for automobiles: | Pollutant | 1970 Emissions | 1990 Emissions | CA ultra-low emissions |
|---|
| CxHy | 1.5 g/mile | 0.25 g/mile | 0.04 g/mile | | CO | 15 g/mile | 3.4 g/mile | 1.7 g/mile | | NOx | 3.1 g/mile | 0.4 g/mile | 0.2 g/mile |
Catalytic converters are used in automobiles to convert pollutants in engine emissions to benign products. Catalytic converters in today's automobiles are made of a porous ceramic brick that has been coated with catalysts, additives, stabilizers, and support materials. Corning has developed bricks that have very thin-walled channels with 600 channels per square inch. Which of the following research goals did they target? |
