What does regen mean when referring to a diseil thanks

 

Regen is short for regeneration.

In Modern diesel speak what we are referring to is the clean of the diesel particulate filter or DPF for short.

The cleaning of the DPF is regen or regeneration.

As it goes thru the cycle of cleaning you are regenerating it for further use.

BTW welcome to FTE!

 

Thanks for the knowledge I'm new to diesel engines so far I'm happy with my truck just trying to learn more about it thanks again
