Regen temp for parked regen

What motor?

 

The target temperature inside the dpf for proper conversion of soot to ash is around 1050*F. I would say anything exceeding plus or minus 150* or so from this number in a regen log from this temp should be looked into as a potential problem.

 

I am doing a park regen right now, my temperature went up to about 200degrees. After it stopped my truck requested another park regen.

 

If you’re needing that many regens, you may need a new filter or perhaps a sensor. You should go see your truck manufacturer.

I should add that 200° is normal temp for your dash to show. Mine goes up to about 225° before the fan kicks in and brings it back down to 200°. But unless you’re interrupting your parked regen, you should never need 2 in a row.

 

I find it awfully hard to believe your exhaust temp is only 200 degrees during a regen. Are you mistakenly looking at coolant temp rather than exhaust temp?

 

Hi,
I have paccar mx 13 engine in 2016 Kenworth. I got some work done on truck at Kenworth dealership related to air compressors. They did update software as well . Ever since my truck been doing regen every 12 to 15 hours . Before that it used to be well over 50 hours . Does new software changes anything for regen cycle time limit?

 

No it does not.

 

So any suggestion that why it regen more often than before. It got no check engine lights or fault codes. It runs normal .

 

Hard to say without digging in. I sure dont make any connection between the air compressor replacement and frequent regens.

How are you timing them, HEST lamp?

How long has it been since dpf and engine managment cleaning?

Did you have any CEL before the air compressor change? Anything else done other that PCI update?
