NJ: Diesel Ram Owner Forced to Scrap Truck Over Deleted Emissions Equipment

I think its because the VGT or backpressure valve loads up the engine when electrical demands are low. Plus the enclosed cabinet keeps the DEF tank thawed. Used to have a ton of issues keeping the older ones hot in winter. Lots of frozen crankcase vents and wet stacked exhausts. I'd load bank them at the shop and some would throw flames out the exhaust at as little 25% engine load.

 

fast to run over rabbits, slow for turtles

 

do you even drive a truck.? Is this A.O.C.?

 

Started in dump trucks and paving for 5 years now on flatbed for 6.

 

Interesting to think about the different style applications and how the engines perform.

 

Part of it was we had one customer that would always pull a 75+ kw gen set out of their laydown and use it to power something a little suitcase sized generator could've handled. At 35 below we just couldn't get the coolant above about 60°C. Basically just running no load at 1800 RPM for days on end, slobbering fuel and oil everywhere.

 

How did you get them hot enough to stop the slobbering?

 

Had them switch the big gens out with ones the proper size for the task. Back at the shop we'd hook them to a load bank and gradually load them up to get the exhaust cleared out. Sometimes bad enough that we ended up just replacing the muffler.

 

I know exactly where that is.
I haven't seen those stacks blow black smoke like that in a long time. For a long time it was the norm
