DEF Systems Can Now Be Disabled if they Fail

Most that I go to have one as well. It’s a loss of deposit or booked stay.

Basically once money paid, it doesn’t come back.

Most I’m familiar with set parameters. The deposit is like earnest money in a real estate transaction. It means you have skin in the game. Otherwise you have situations like many State Parks encounter. An RV’er books several campsites, when they arrive they pick the one they like and cancel the others. In the interim, those sites are shown as reserved to other campers looking to make a reservation and likely go unoccupied for a time.

There are countless reasons someone may want to cancel, and most parks I know do their best to work fairly with guests. But when you commit to a site and the park takes it off the market for you, that site becomes yours. Expecting the park to absorb the cost of circumstances beyond their control isn’t reasonable.

Philosophically, I agree with the use of DEF to reduce atmospheric pollution. My issue is sensor failures that can leave you stranded on the side of a busy interstate highway. I’d be perfectly happy with DEF if I just filled the tank when empty and didn’t have to worry about sensors making sure input in the right stuff, right temp, etc.

I applaud the policy change and hope it will allow reprogramming our systems to disregard DEF temp, concentration levels, etc, and not derate our engines. In the meantime, I’ll keep my emulator close at hand and hope my (second) DEF head keeps working as I’m now out of the warranty window.

Well, here’s what I believe. DEF might have been a good thing, but it is not. #1- It wasn’t applied across the board. It was only applied to the small fry. No locomotives, river boats, generators and many, small horsepower tractors and equipment, and many others. If you notice, your generator on your motorhome doesn’t have it.
#2- The DEF equipment is junk. The equipment is substandard and causes substantial problems when it detects issues. Some of which are safety concerns. Tee huggers can say it’s good all they want, but until a system isn’t applied to everything it’s not going to work.

I agree with Charlie…the DEF system is a good idea, it is the quality of the components is the problem. And I also agree that I do not miss the horrible diesel smell. I know it’s a lot easier on DW when I am backing up the rig into a spot and she is assisting.

As far as the environmental issues resulting from DEF, I was not able to find evidence of what Redbaron was stating. I would like to see where that data comes from. My understanding is that the exhaust is free of many of the harmful components due to the breakdown and conversion of pollutants rather than just keeping them out of the air. See below.

“The chemical reaction between the urea in your DEF and the NOx in your untreated exhaust breaks NOx down into water, oxygen, and carbon dioxide. These chemicals are far less harmful, reducing air pollution and minimizing human health risks.“

How can it be a good idea when it’s only applied to a chosen few?

Then we need to improve the technology and apply it to more platforms…not abandon it….

No. We need to do away with what we have. Maybe design something else. Obviously what we have isn’t working. Don’t apply it until it is proven and then across the board. [mod edit: removed]

Okay, let's get back on track. A few posts removed that got sidetracked by bad content. Focus people...focus

I didn’t see anything about bad content. I guess it’s all about you.

Really it's about not being offensive.
