these engines run hot naturally due to the added injection cycle for emissions.

stupid epa but the good part is the pistons and other internals have coating on them that helps them handle the heat

Isn't the added injection cycle only performed during active regeneration?

If burning or unburnt fuel was sent out the exhaust in common application, wouldn't that make EGR kind-of an explosive proposition?

i would suggest water/meth injection for you guys running 1600F egts because that engine isnt going to last very long. i know cummins are strong and have that layer on the pistons but thats just too hot

No. Soot is partially combusted fuel, it will not burn explosively again. If it did then DPFs wouldn't exist!

Then you better stop all those engines from doing regenerations!
