Cummins x15 Parked Regen

Which ISX are you speaking of, CM-870, CM-871, CM-2250 or CM-2350? They all have their down sides, and none are set up to idle with the emissions, other than the older 870.

 

X15 replaces the ISX.

 

Yep, but more than a few guys use the X and ISX as generic terms. Just trying to get a clarification. Not much out on the X15 to make a call. The rest, like I said, they have their issues, which I am sure the X will too.

 

Yes, you can do a forced regen. Why are you having to do one?

If you have to do a forced regen for that long, you have issues. Do you have an Inline 8 reader and Insite? You need to see if any codes are showing. Sounds almost like the DPF is plugged. These X15 motors have a new style emission system on them compared to what most of us are used to. I would suggest going over to Rawze.com and asking over there. What you are experiencing does not sound right.

 

I am sure it would be convenient, but I do not know if it is advised. The emission set up on that unit is a new and "improved" model. I would call Cummins and hope you can find someone that has a clue on the question you are asking. I would also head over to Rawze.com and ask over there. There are a few guys that are working on these new X15 units over there in trucks. These are mechanics, not a driver like myself. There honestly has not been much reported on these new motors to tell you anything definitive that I have read. I own the CM-871, and the EPA issue has been done away with a few years ago.

 

Being that you're running a loader (going to assume it'll be running off a PTO like almost all do), you're going to have that engine loaded up to some degree anyways to power the hydraulics. That's going to help keep heat in the engine vs just running at 1000 RPM under no load. One thing to consider and maybe even quiz Cummins on is if the truck will even do a parked regen if under load. Also you're going to have engine RPM fluctuations quite often when you're running the loader. The regen algorithm in the ECM might not like that and cancel the regen because it won't keep a constant RPM.
