thanks guys for all the answers.
I have read somewhere that the EGR valve helps in warming up the engine more quickly en in fuel efficiency? is this true?
How does this EGR thing in the circle work? does it open up something that is underneath it?
How should this whole thing be connected? should it in any way be connected to the valve in my exhaust?

In my other topic it is discussed in page 3
