Achieving future diesel engine emissions with cylinder deactivation

Global emissions regulations for commercial vehicles are becoming more stringent. Cylinder deactivation (CDA) has been proven to be a key solution to meeting these regulations by improving diesel aftertreatment performance during low load operation and providing fuel savings. 

Eaton has nearly twenty years of experience with cylinder deactivation for gasoline engines.  Now, we're building on that expertise to develop solutions to help medium- and heavy-duty diesel engines meet future emissions regulations.

For nearly a decade, we've collaborated with experts in academia and our industry to develop and test diesel cylinder deactivation.  We've done the research and the answer is clear: cylinder deactivation is proven way to lower NOx while at the same time reducing CO2 (fuel consumption).

We held a series of webinars titled Engage The Experts, where we explored various aspects of cylinder deactivation (CDA):

  • How does cylinder deactivation impact the noise, vibration, and harshness (NVH) of a diesel engine?
  • How can cylinder deactivation help diesel engine manufacturers achieve 2024 and 2027 emissions targets?
  • What are the results of using cylinder deactivation in real-world drive cycles?
  • How does cylinder deactivation compare to other technologies and combustion techniques?
  • What is the difference between cylinder deactivation and cylinder cutout?

Our Engage The Experts webinar series can be viewed anytime.

A system-level approach

Rely on our extensive system expertise for your engine solutions.  Eaton’s Variable Valve Actuation (VVA) solutions for commercial diesel engines enable combustion strategies such:

  • Cylinder Deactivation (CDA)
  • “Miller” cycle (EIVC / LIVC)
  • Early Exhaust Valve Opening (EEVO)

Variable valvetrain functions reduce fuel consumption, help to heat the exhaust for improved catalyst efficiency and thus lower emissions.

Whatever the variable valvetrain need, Eaton has a solution that can meet the requirements.
