LSI Posted June 17, 2011 Share Posted June 17, 2011 I saw a posting on another site that the MP8 does not have EGR.Only SCR and DPF.Is this true?How often do you have to clean the DPF?Does it regen?Or does it only do a passive regen while going down the road?

rhasler Posted June 17, 2011 Share Posted June 17, 2011 The US10 emissions MP8 still has EGR. The amount of EGR introduced into the cylinders is lower than in previous years. The engines in some circumstances may have to be manually regened, but for the most part the regen is passive. Quote "Mebbe I'm too ugly and stupid to give up!"

Mackpro Posted June 18, 2011 Share Posted June 18, 2011 I saw a posting on another site that the MP8 does not have EGR.Only SCR and DPF.Is this true?How often do you have to clean the DPF?Does it regen?Or does it only do a passive regen while going down the road?We have never had to change the DPF filters on any of our Macks except 1 time when a turbo went out and filled it full of oil. Some of our trucks have 600,000 miles on them. On our SCR trucks ( about 6 total) no one has ever had to do a parked regen, it seems to do the regen going down the road and thats not to often.
