Prior to the mid 1980s the catalyst material was deposited on a packed bed of alumina pellets in early gm applications metallic foil monoliths made of kanthal.
Titanium or ceramic cadillac converters.
The inside of the catalytic converter is a honeycomb set of passageways or small ceramic beads coated with catalysts.
Our universal ceramic catalytic converters fit into a vehicle based on size oal mantle od etc shape and engine displacement 3 8l 5 9l 6 2l etc.
An overly rich air fuel ratio i e.
The catalytic converter s construction is as follows.
When manufactured in large quantities ceramic cores can be inexpensive.
The catalyst support or substrate for automotive catalytic converters the core is usually a ceramic monolith that has a honeycomb structure commonly square not hexagonal.
The catalyst core or substrate.
A universal converter which does not typically have inlet outlet extension pipes may be used in hundreds of vehicle applications and can be welded onto an exhaust system when the existing.
This is partially a cost issue.
For example when these devices are used in automotives the core is usually a ceramic monolith with a honeycomb structure.
There are many passages for the exhaust gases to flow to allow for the maximum amount of surface area for the hot gases to pass.
These catalytic converters are not for use on vehicles registered in california as a result of california vehicle code sec.
11 5 1 or lower or operating temperatures exceeding 1200 degrees can cause premature catalytic converter failure voiding the warranty.
For automotive catalytic converters the core is usually a ceramic monolith with a honeycomb structure.
A chemical reaction takes place to make the pollutants less harmful.
Metallic foil monoliths made of fecral are used in some applications.
