Eaton Diesel variable valve actuation

Upcoming diesel engine emission regulations will require significant reductions in NOx and CO2. The key to achieving this is maintaining the aftertreatment temperature in a sweet spot and maximizing the engine's thermodynamic efficiency. Eaton has developed several variable valve actuation technologiesÊforÊmedium- and heavy-duty engines addressing both needs:

• Early / Late Intake Valve Closing (EIVC / LIVC) orÊ"Miller" cycle
• Cylinder Deactivation (CDA)
  
• Early Exhaust Valve Opening (EEVO)
