Lots of EGR info in the archives, look there for more.

Briefly EGR is "neutral" as far as combustion is concerned.  Adding EGR
doesn't make the air/fuel mix leaner or richer.  It lowers combustion
temp (not as much fuel to burn) which helps emissions.  It also helps
fuel economy by reducing fuel at part throttle conditions.
