CCRT Diesel particulate filter on a 2000
I saw an auction bus that was listed as a 2000 with a 5.9 cummings, and that it had a CCRT Diesel particulate filter installed (specifically called out).
I thought at least federally that particulate filters weren't required that early. (this one was in Oregon).
So is this an aftermarket add on kind of particulate filter? Or is it tied into the ECU like alot of the modern ones are (I believe that the regen cycle causes the engine to run rich to raise exhaust temp and burn out the particulate).
I'm thinking if a previous owner had added a catalytic converter to a classic car and it wasn't required, you could legally remove it, and the car wouldn't care. With some of these systems, they weren't required at the time so I would assume they could be removed, but if its tied into the ECU I imagine it would throw an error or would simply run the regen cycle occasionally and freak me out because exhaust temp would rise.
Anyway, thought I would check with the group to see if anyone had run across these before. Should they just be treated the same as a 2004+ bus that has extra emissions gear, and just realize if you buy it, you are going to have to live with it?
