ASK A QUESTION catalisador de carro
Hello Wendy, welcome to the Forum.
This is a learning site, and you're most welcome and encouraged to come in, participate, and learn lots! But we don't "translate" - we expect our members to make an effort, and then we offer corrections.
We do, however, have a nifty online dictionary and translator utility that you are most welcome to use.
If you write "catalizador" (this is the correct spelling) in the box above, and click on the "translate" button, you'll get the answer you need.
This seems to be a reference to a cars catalytic converter, a part of the exhaust system.
