(possible thread jack/clear outta left field type drift) I openly ask this of any of the "gotta delete 'em" group:

What kind of planet do you sincerely believe you are leaving for future generations by your actions?

No, I don't mean to say that I am a clean air making saint, I have a 3/4 ton pickup and haul a travel trailer with it, but the emissions equipment is intact, and as far as I can tell, working properly. I drive as efficiently as possible when and where possible, but I hope I am not doing excessive damage to the future by my actions.

My hope is that people realize that while just your deleted rig isn't gonna cause life as we know it on Earth to die, thousands or millions are not helping at all, and may be doing untold and possibly irreversible damage.

I'll bet those that we now know were causing incredibly dangerous pollution during the various industrial and other discoveries and booms throughout time didn't think that they were doing anything wrong, either. I'm sure they believed they were making things run right, too.

This can take so many turns:

1. What about the regen process when you are dumping out raw fuel, sometimes in to the exhaust?

2. What about these consumable products nkown as RVs that are just wasting resources on "fun" most of the time, and then take up land fills. Not to mention the excess fuel you are wasting by having "fun" with it, when you could save it for the future generations.

3. What about "green" cars? These Prius's with batteries that are more toxic and produce the same, if not more waste than a diesel's life time?

Take your pick.

Electric cars get 67% of their energy in the US from fossil fuel power plants. 39% from coal alone.

I'm sure we could all point out pluses and minuses of current attempts to clean up the mess we've made of our planet. The OP asked about kits that remove some of the devices added to a diesel pick up to make it fit current emission regulations. 1bigmess is making a point that it's not good for the environment, a place we all bought RVs to enjoy. I suggest we all stop taking such an attacking tone.

No.

If you are going to run an RV, or a work vehicle, or even a two stroke off road only dirt bike, why make it ((**MORE**)) polluting by tampering with the emissions controls?

Don't like the EGR? Don't buy it.
Don't like risking money that a vehicle has a system that will be difficult and expensive to deal with? Don't buy it.
Already got one? Sell it and get what you really want or will fit your needs better.

But don't join the already teeming masses of folks that are thinking "I'm not harming anything due to tampering with emissions equipment". Of course, *you* alone pretty much aren't. Together, all of you are.

Electricity that comes from a process that is cleaner and more efficient than internal combustion. Running an electric car or hybrid down the road is cleaner by far than gas or diesel IC alone, no matter how you slice it.

Electric or hybrid technology has not been scaled up to a point where it is viable technology for the consumer RV market at this time. My opinion is get what you can that will do what you need and don't tamper with it's emissions controls.

To those that bought vehicles with emissions controls that are problematic, I am not sorry that happened to you. We all roll the dice when we go to buy a vehicle. Even with the extensive research I did before buying, I could still lose my shirt and more. We're all bobbing around in pretty much the same boat here.

Emission controls are there for a reason and have made our urban areas much better places to live.

Not a Prius fan but might buy a hybrid. As far as their batteries go.


Quote:
After being removed, the battery pack is sent to specialist recycling firm Kinsbursky Brothers in Anaheim, California -- the same firm responsible for recycling used lithium-ion battery packs from Tesla.

On arrival at the specialized facility, battery packs are broken down into their constituent parts, with nickel being smelted down for stainless steel used in making refrigerator doors, while rare-earth elements, plastic casings and electrolyte are all recycled into appropriate industries.

Ultimately, the whole process is a win-win scenario for everyone involved: dealers get extra custom, and customers get to choose between a newer model with even better gas mileage or a new battery pack. More importantly perhaps, not a single traction battery pack ends up in landfill, proving that batteries -- no matter what their chemistry -- are still the most recycled consumer product.

My comment about the emissions systems eventually needing to be replaced was to show that a delete or replacement may be necessary in any event if purchasing a used vehicle with higher mileage or unknown usage.
Following this thread with interest for several days...... The above comment about acheiving a 25-30% increase in fuel economy begs a challenge. Not on your best day & only in your dreams.......

At best... maybe 1 to 3% .....if that. Likely less. Look at the VW dynometer tests between EPA & road tests. The difference between the two are nearly insignificant. (And I suspect that the claims of huge emission increases are hyperinflated as well. 100% of almost nothing...is still almost nothing on a car by car basis. )

To get 25-30% improvement you would need to remove everything behind the front bumper.

Clogged DPFs are indicated by Check Engine light and get possibly limp home mode. So, you aren't going many miles anyway if the DPF is konked.

From what I've read and experienced an SCR/DPF/DEF equipped diesel gets better economy and reduced emissions over the same engine just a few years ago. The problem, if it exists, with clogged DPFs is very likely due to not using low sulpher & ash oils and/or substandard fuels. The whole point of regeneration is to reduce the carbon collected into gasses at very high temperatures and that may take a very slight increase in fuel use. Overall, despite using fuel in regen, there is a net improvement in fuel economy.

To be clear, the purpose of DPF is not to remove the highly visible black soot. That is taken care of elsewhere in the combustion process. DPF removes the nanosized carbon and particulate nasties. Nanometer size particles that you breath in; particles that lodge in the very small air sacks and anatomy of the lungs; particles that are not expelled from the lungs; particles that can and do cause airway disease and cancers.

Despite the hearsay, Grand Pap wisdom, and other sources of mis-information....today's DPFs and catalytic converters do not contribute significant back pressure in the exhaust and have very little, if any, effect on performance and mpg. If you want to reduce back pressure....remove the turbo. If you want better MPG .... Reduce the weight and your speed.

going by actual observed gain on a 2012 Ram 6.7.

12.6mpg -> 17mpg empty. over 30% gain. This is on pre-DEF Ram 6.7

Yes, all day long.
I average 19 now. (2wd)

You forgot about inflating tires and getting a tuneup.

Just curious if you have ever driven behind a diesel in regeneration mode? I'm quite sure that breathing in fumes from burning diesel soot is very healthy.

But how often do you find yourself behind a rig in regen?

If the regeneration mode just burned up all the soot and by-products accumulated during driving then released them all at once, you might have a case. Fact is, the regeneration mode converts the accumulated deposits into less harmful emissions, so 'breathing the fumes' wouldn't be a chore. The particulate filter in modern diesels reduces emissions by 90%, and that's not something to sneeze at.
