Surprised
I was surprised yesterday that after being slowed down to between 5-15 mph for the better part of a hour on the I-10 west of Phoenix yesterday. After all that slow driving with a lot of stop and go. I was really surprised that we could go that far and not have to do a parked regen.
That was the first time and the longest I have ever gone in that kind of situation.
Just thought I would pass this on.

Do you need frequent parked regen with your MF 10 ? With our MF 7 we are yet to have to do a parked regen at 28000 mi. We have certainly been in slow traffic for long periods and the question has come to my mind that at some point we will need to have that experience. So far so good.

OK I'll bite... What's a 'parked regen'?
Thanks

No I don't just kind of figured with that long at slow speeds it would have required one. I have never driven that far or that long at slow speeds before so was kind of surprised. We have 28,000 miles also.

Short answer. Modern Diesel engines are equipped with a filter to trap exhaust soot. The idea is that a regen occurs when the soot level rises. While parked the exhaust temp increases to a high level to literally burn off the soot. This process should occur infrequently as driving at highway speeds should rid the filter of excess soot.

Thanks, I would have never guessed. We have a gasser.

From my diesel truck experience I know what a regen is, but for a "parked regen" do you really have to be sitting still? Why can't it regen while driving? Curious.

Under normal driving conditions you would never know that the coach is doing its regens, but if the soot level builds up to much in the DPF you may go into stage 2 or stage 3 and have to do a parked regen.
The conditions we we're driving in we're what could cause a parked regen. I was just surprised that we could drive that slow for an hour and not have to do one. For myself in 28k on the coach this was the first time we drove that slow for that long.

Thanks for the explanation. I've never heard of a "parked regen" until now.

We just rolled past the 39,000 mile mark ... of which, 20,000 miles were ours. We've had to perform a just one "parked regen" - and to be honest, I suspect that I jumped the gun on that one. The "parked regen" light came within a couple of minutes of starting the engine (meaning things weren't completely warmed up...). I did what the lights told me - but suspect that had I of simply continued driving until the system was up to temp - it would have cleared on its own. Seems like some folks have horror stories regarding regen issues ... others (like us) have had no issues with it.

Actually, I think you have to be parked to do a parked regen. When the lights tell you that is needed it means that the filter is dirty and the engine is going to "derate", cutting back on your power so that until completed you will literally only be able to limp along. During the parked process the RPMs increase and the exhaust becomes extremely hot allowing the soot to be burned off. Mind you I've only read about this and have not yet had the experience myself.

The only reason I brought this up is I have had to do 2 parked regens in the past, both we're due to excessive idling and running without warming up enough (1-was while in Coburg for factory service where they pick up the coach in the AM and bring it back to you in the afternoon.)
Both regens we're required before I had the ECM brought up to date with the latest update.
I was just surprised that I could go that far in those conditions where automatic regen likely wasn't able to take place. (I;m told you have to get up to at least 45mph and stay at that or faster for the auto regen to work)

I've only had to do one parked regen. Most recently after leaving Alliance Coach and heading back North the 2nd stage light came on while entering I-75. Power was reduced but I pressed forward and it cleared after about 20 miles. I try to keep the rpm's up around 1500 whiles driving in slow traffic. This means using the trans keypad to stay in 2nd or 3rd gear. It's the engine rpm not mph speed that will clear the dpf.
