Retrofit DEF for CARB?

Volvo didnt introduce DEF until the 2011 model year. My truck has a built date of 2009 and is an EPA2010 engine. How did that happen. I bought that way.

 

I remember vaguely that around that time enginebuilder were working with credits.

 

EPA 2010 was the introduction of Low NOX motors. For whatever reason Volvo was able to do that without DEF. It's like a 1 off motor since every other manufacturer was already doing DEF. Volvo starting with 2011 began using DEF to meet the Low NOX requirement.

Hopefully my information is accurate and I am going off of memory. But if I am wrong Sorry.

 

EPA Certifies 2010 Engines from Volvo, Mack Trucks

Some info on this topic.

 

None of those engines came spec'd for EPA2010. Short answer.. No.

 

Well 5 and 6 are already compliant now 4 can be but has to be verified on the engine


Nobody does that kind of work. I would imagine the work required to remap/reengineer motors would be very expensive. It would make more sense to buy a new piece of equipment and be done with it.

 

Does said engine still have the emissions it had when it left the factory?
