CARB and PVT Diesel Trucks

I remember a factory EPA type sticker on a 1989 C-series fire truck engine (Cat 3208)

This engine does not meet [x] spec but it’s OK because the fines have been paid.

2006-ish Cummins 8.3 liter engines had high pressure common rail and catalyst, but no EGR, they used credits from the larger 15-ish liter engines to keep the smaller ones more simple.

Remember the Ford ambulances with the same old 6.0 diesel in the van chassis, long after everything else had gone to the DPF 6.4 or whatever?

No new thing under the sun. Always cutting and sewing the blanket.

Ford 6.7 Super Duty line of vehicles has regularly had “emission update campaigns “ Our 6.7s have had 5 updates combined since we owned them. You can not get your tags thru the DMV if you don’t have the updates completed. It’s absurd to see how many other owners will have there DEFs reinstalled on there deleted trucks to get them to pass the updates then re-delete the truck afterwards, only to put the DEF back on a few years later, for another update. I like power, but man I’m not that motivated.
