Development of ceramic and metallic
supports with thinner walls and increased catalyst surface
A larger catalyst surface area can be fitted
into a given converter volume. This gives better efficiency and
Alternatively, the same performance can
be obtained from a smaller converter
This makes the catalyst easier to fit close
to the engine in small cars.
The thin walls reduce the amount of heat
absorbed, so temp stays higher
By how many times has the wall thickness
How many times has the cell density been
What benefits do you think these advances
in materials technology bring?
