Selective Catalytic Reduction

How does it work?
Selective catalytic reduction (SCR) technology is an after-treatment system. It breaks down the NOx produced during the combustion process into nitrogen and water, which occur naturally in the atmosphere, through a chemical reaction with a diesel exhaust fluid (DEF).

The combustion process is optimized to reduce PM, so that no particulate filter is required.

What does it mean for you?

  • Low fuel consumption: The combustion process is optimized for maximum efficiency, so less fuel is consumed.
  • Optimized performance: Torque and power are maximized, as SCR is an after-treatment system that allows the engine to do what it does best – generate power.
  • Simple Design: You only need to refill the DEF tank when the level indicator flashes.
  • Easy-to-find: DEF will be readily available through CNH Parts & Service at your local New Holland dealership.
