Are you serious? You searched the internet and couldn't find what one does, how bad are your search skills

In a nut shell they catch/seperate oil vapours so the oil doesn't build up in your intake system.

You can have them venting to atmosphere or plumbed back in, the later one being the legal option.

Crank cases are pressurised and therefore need to vent somewhere, from factory this venting goes back into the intake and on an engine with a few km's on it the oil vapours can get quite substational which leads to many negative effects. People install catch cans to stop this oil depositing throughout their engine, instead being caught elsewhere (the catch can). It's a mod most of us most likely have.

Hope that helps. Seriously just do some more searching, catch cans aren't that complicated.

I have this snippet in my notes if it helps, it was helping my clarify air/oil separator vs catch can:

Catch can is a bit general term to use..

Catch cans are there for engine failures type issues so the oil is caught in that rather than sprayed all over the road/track .. this is a must have in every form of racing i've been involved with.

Oil air separators that can do the above job as well are for removing the oil vapour from the air leaving the head. and not re-introducing it into the combustion process.
