Externally cooled Exhaust Gas Recirculation lowers cylinder temperatures pre- (and therefore post-) combustion. It is used primarily to reduce nitrogen oxide (NOx) emissions, which are created when Nitrogen and Oxygen (main components of air) interact at high temperatures. Because it's replacing air/fuel to be combusted, it can result in lower power efficiencies if applied incorrectly, but the cooling effect can sometimes be significant enough to cancel that out (less heat absorbed by the engine = more work produced by the piston).
