The EGR valve in computer controlled engines allows the computers to run the vehicle at a more lean rate without destroying valves and/or pistons. Only a small percentage of the exhaust gas is allowed back into the combustion chambers; just enough to reduce the oxygen percentage in the air mixture, thereby preventing the super-hot combustion that takes place when the fuel in the mixture is reduced. Carbureted engines are deliberately run at a more "rich" mixture to prevent the destruction of the metal parts.
Another answer:EGR. Exhaust, Gas, Recuirculation. It runs the exhaust back through the motor, to burn any unburned fuel, before exiting the tail pipe. It actually aids the catalytic converter. This is what allows the above answer to hapen.
