DEF Systems Can Now Be Disabled if they Fail

[DavidL]

I am glad that when DEF equipment fails our rigs are no longer required to be instantly bricked. That was indeed a lame requirement. There should have been a built-in grace period to get the issue resolved vs. Being sent to the penalty box immediately.

However, I am also in favor of reducing my vehicle emissions by almost 90% and emitting harmless water and nitrogen gas. Not choking on harmful nitrogen oxide is a good thing.

I haven't read the new regulation re: DEF....is this going production forward or also backwards? Mine is pre-def so, no Diff to me but curious. Maybe thats the rub that is keeping RedBaron from marketing an aftermarket solution...

Don’t want to hurt anyone’s feelings, but def was never a good idea. What a disaster it turned out to be. The best thing they can do is do away with it. Delete, delete, delete. If it worked they would have applied it for every engine that used diesel. All that regulation did was cost a whole bunch of people a lot of money and put many people at risk.

I date back to when the first diesels started showing up on light duty vehicles. They were noisy but unless they were modified there was no visible smoke. When they started adding turbochargers the HP increased and emissions were reduced. Changing the injection systems was also a big improvement.
Fast forward to more recent times emissions have improved but I have one issue. For those who say there is no odor i can assure you when I am stopped behind a diesel at a stop light i can smell it from 5 vehicles behind. So much so I have to put the hvac on re-circulate to stop from drawing it into the cab. This is true for older vehicles up to brand new vehicles.

I'm all for deletion but when they 'roll coal' I think the owners should be prosecuted.

I can tell you, I deleted mine. Gained HP and gained 2 miles to the gallon better fuel economy. Nobody can make me believe that burning more fuel and getting less performance is better for the environment. The people that profess that also want everyone to use an electric vehicle.

I hope yours doesn't 'roll coal'.

Science? Big difference between the harmful impacts of what nitrogen oxides do vs releasing nitrogen and water vapor instead. That said, immediately bricking an engine vs a 500 to 1K mile grace period has always seemed like overkill on the compliance side.

And yes, I also like that my electric car saves me over $4K a year in fuel costs even when you factor in my higher electric bill for off peak charging.

But I'm an engineer...

Alternate theory: Those manufacturers who were not required to do it probably paid a ton more $ to better lobbyists to bribe lawmakers to carve them out an exception/waiver.

My deleted vehicles do not roll coal, do not produce any visible emissions, and don’t sound obnoxiously loud.

I did add a different muffler to quiet the sound that was previously reduced by the SCR/DEF systems.

The construction and farm equipment that we operate cannot afford to be down due to emissions. After having a tractor/trailer stranded for 2 days due to DEF issues I couldn’t risk this again. This time we didn’t have any horses in the trailer, but it would have been a disaster if it happened on the return trip. Many mechanical items can be maintained and give a warning when they have issues before just going to limp mode.

I feel that I am doing the world a favor by now consuming less petroleum products due to increased power and efficiency. (This is sarcasm….don’t flame me )
