The diesel industry is entering another major emissions transition.
Beginning with EPA 2027 heavy-duty emissions regulations, diesel engines will face some of the strictest nitrogen oxide () standards ever introduced for commercial vehicles.
One of the biggest technologies helping manufacturers meet these standards is the 48-volt heated aftertreatment system.
This system is designed to:
- Heat emissions components faster
- Reduce cold-start emissions
- Maintain catalyst temperature during low-load operation
- Dramatically reduce output
Modern diesel engines already rely heavily on aftertreatment systems.
However, EPA 2027 standards require emissions systems to become even more effective during:
- Cold starts
- Idling
- Low-load operation
- Urban stop-and-go driving
That is where heated aftertreatment systems become important.
