Maybe 50 to 100 deg. F at best. The high temps are in the exhaust NOX/DPF filter. Everything upstream of that is pretty much normal from my observations. See this video on an entire active regeneration. Catalyst (DOC), a chemical reaction occurs, and the exhaust system temperature increases to a level that oxidizes the soot in the filter. W2005917 Aftertreatment Fuel Injector (AFI) The Discharge Recirculation Valve (DRV), mounted on the charge air cooler inlet pipe, increases exhaust system temperature by recirculating air back into the ...
