Cylinder Deactivation

Eaton Cylinder Deactivation - CDA system is the most direct way to reduce CO2 emission, and at the same time improve fuel economy through driving cycle.

It overcomes the obstacles of designing a high performance engine that is optimized for fuel efficiency.

CDA deactivates the cylinders of the engine whenever full power is not needed. In that way, remaining, active cylinders run in higher efficiency mode, increasing fuel efficiency.

Eaton is an expert in engine air management. As such, we offer a variety of cylinder deactivation solutions for Type 2 valvetrains including:


  • Hydraulic Lash Adjuster-based
  • Roller Rocker Arm-based
  • Roller Lifter-based
  • Camshaft-based
