Add on DPF

To Diesel Dave,

So I am assuming that these retrofit's are all Passive DPF's meaning they are just a blow thru filter, no Doser vale or plumbing, no regens, no ECM upfits?

What is your bake out interval on that filter, I had looking into it on an S60 that I wanted to put in a glider, but we run long haul and rack up over 150,000 per year per unit, they gave me a bake out or exchange schedule of every 50,000 miles, that just won't work in my operation, as we go 300,000 on our 2010 factory filters, and it's NOT cheap.

How does your DPF compare? Thanks Stan

 

I just my install in April of this year. I run locally and average about 50,000 or less a year. I been told by the certified installer that 50k is the average it should be baked to avoid the build up. The more build up, the harder is to remove what is completely is baked inside the filter, equals less life on the filter. Now, I had a member on here PM me and he was running another system which I heard of BUT I never seen one and its a complete after market system where it bakes and/or cycles on the truck. I cant recall the name. Maybe that is something that might be better efficient for your operation. Let me look it up and will get back to you.
OKAY LOOK IT UP, Its call the "Johnson Matthey Unit", comes with the pre burner and passive.

 

we cannot discuss deletion of such products, but we can discuss add on of such products?

 

I would put a test pipe in place of the DPF filter and you'll never have to bake a filter.

The retrofit filters look just like a muffler anyways, with a probe inserted into the elbow, which goes to the datalogger.

Since the datalogger is independent of the ecm, installing a test pipe doesn't affect anything in regards to the engine operation.

 

DD was referencing my system,,it is a Johnson Matthey with a pre oxidation catalyst in front of the filter(it is all one unit but it is able to be separated for cleaning),the recommended cleaning interval is every 50,00 miles(pulse cleaning-not baking),but when my unit was installed the testing indicated that i could go up to 100k before cleaning since my opacity numbers were around 4(almost no smoke),,currently i have only cleaned it once since installing Jan 2014 and my unit has over 160k on it now(due for another cleaning),,the installer I used offers a monitoring program that tests my system for $85.00 to determine how soon i need to do a service on it(usually when i see a warning on the display,I have them hook it up to the computer),my first warning light came on at about 80k miles,,they tested it and said it was still ok,,then i got another light 2 months later so i had it pulse cleaned,,haven't had a light yet since cleaning/testing the last week of November,,,one thing to note-the warranty is for 150k miles/5 years,,you will exceed the miles long before the time,,,if you have a new engine they will give you 200k miles but you need to document the new engine prior to install

 

now if i can talk DD into putting his 550 BrakeSaver file into my ECM after i replace my injectors,,I'll probably have to clean it more often,,

 

when you get pulled in for a random,,they check for soot on the exhaust outlet,,so that would not fly

 

Javelinjeff, how spendy is your system? Warenty?

 

cost me $15,600 plus $375 for data logging,,5 year/200k warranty since my inframe was only 8 months old when installed. was able to finance through Lease Corp of America what i didn't have to pay in full
