It's hard to find any info on exactly when and how this works, but here are a few more scraps.
  • Supposedly this valve can partially block the intake to allow more EGR into the engine.
  • The valve closes the intercooler when the diesel particulate filter needs to be burned out. Allowing warmer air into the engine helps raise the exhaust gas temperatures.
