How DEF Injection Works
Understanding the science behind selective catalytic reduction technology
DEF Injection
The injector precisely delivers diesel exhaust fluid into the exhaust stream before the SCR catalyst.
Thermal Decomposition
High exhaust temperatures convert DEF (urea solution) into ammonia and carbon dioxide.
Catalytic Reduction
Ammonia reacts with NOx over the SCR catalyst, converting harmful emissions into nitrogen and water vapor.
Clean Emissions
Up to 95% NOx reduction achieved, meeting the strictest environmental regulations.
