DEF going away ?

[Hay Dude]

What we all have to step back and realize is some states are a lot more expensive to maintain & repair than others. Therefore, their taxes may be higher. Or it could be just plain old corrupt governing.
PA is in particularly poor condition. Roads, bridges, tunnels, railroads, schools, etc are pathetic. This state has been run into the ground and is the best example of “rust belt” you’ll ever see.
You drive around and you’re shocked at the dilapidated, crumbling junk (if it’s not overgrown with trees & weeds to the point that you can’t see it anymore).

PA has more abandoned railroads and factories than most states have active railroads and factories.

I had that problem with my FIL borrowing my Deere 4044M. I was told and read it had to run at 1500 RPMs to avoid regen mode. I do everything at 1500 plus and use gears to go slower or faster. FIL had no idea, and told me it got louder when he was using it. I suspect he turned it off while in regen. He had never run a tractor at higher RPMs. It eventually went out of regen mode, but it took way longer than normal. I almost never see regen running at the designed RPMs.

I have a Kioti NX4510 HST. It does not matter what RPMS that I run it at. Usually between 30 - 40 hours it will do a regen. That normally lasts 20 - 25 minutes. I have had lots of issues previously with the turbo, injectors and the DPF exhaust. Since 770 hours it has been very good. I think it has 1650 hours on it now.

I couldn't imagine if every diesel going down the road did that.

Good Pot - thank you from the future

What we don't have to imagine, but might all recall (likely find lot of video on the subject) is what our world (big cities and small) noticed during the lock down that was so dramatic that broadcast stations across the globe were sharing before and now images.

Splitting hairs excluding one source of pollution because it contributes a bit less than another is the route to failure to perform.

The expression 'Spaceship Earth' is worth repeating and comparing it with the ISS orbiting the former. Imagine if an astronaut lit up a smoke onboard the ISS!

Earth is floating about in the same space. Protected by our 'atmosphere.'

And we're actually seriously considering abandoning efforts to pollute less - even some folks cheering that on?

The scientists and engineers that built the ISS, or that Moon Lander, the Mars Lander, the lander they sent on a ten year mission to land on a f***ing comet - the guys who know this s**t inside and out; people that really study this stuff, take samples, record the data, replicate the experiments requisite to putting men and women on the ISS and maybe, one of these days Alice "to the moon" are telling us that the data they've collected, published, shared and analyzed supports what common sense has long suggested, that man is polluting his environment "Bigly" to get all presidential about it.

Couple these facts with the fact that the U.S.A.'s 350 million persons constitute less than a quarter of the world's population and the world's population is going to double - likely before we have any chance of turning the Global Warming around - it is more than likely those surviving when the temps get really bad will be pissing on our graves if they aren't recycling every available drop of liquid containing any water.

@ deezler,
Yeah, I’m definitely laughing at you for sure, as usual.
You have the right to your opinion, as silly as it is, but when you say “DPF and SCR technology is reliable and robust” you are simply Full of

It’s NOT reliable. It’s NOT robust, either. It leaves trucks & equipment stranded helplessly all over the country with failed sensors.

You don’t own/operate trucks and equipment on a commercial user basis, so get back in your 30HP tractor lane, and stop talking about things you have no knowledge of.

Again, I'm sorry if you've experienced that kind of trouble personally, or heard many a complaint from your peers.

My tractor is 35 HP, thank you very much, haha. But "my lane" is actually in the industry as a tier one supplier, closely partnered with the OEMs producing internal combustion engines for the CTOHI industry. My employer manufactures a wide variety of engine components, sells to nearly every engine manufacturer, and I manage our engine dynamometer lab to test all of it. So I am deeply integrated within the industry that relies on and sells this emissions compliance technology in all of their engines/vehicles.

I can tell you this: none of the OEMs are talking about warranty concerns, problematic DPF/SCR systems, or anything like that. There were a lot of teething problems 10 years ago, sure. But the broad industry perception is that this is a solved issue.

Maybe you should try a brand new truck instead of driving all those old beaters with early emissions compliance systems.

Edit to add: We actually had our quarterly engineering review yesterday and got an emissions and policy legislation update from our resident experts - DPF and SCR isn't even on the table for repeal at the EPA, tailpipe emissions criteria will remain as is.

 

[deezler]

It's unbelievable really. Everything on them is geared for emissions control, right down to the fact that most of our OTR tractors are automatic transmission equipped, with the claim being, better for fuel economy, emissions control, etc. If it's not the emissions systems directly causing the breakdowns, it's the automatic transmissions!

Oh, that sucks. So a transmission issue, whether mechanical or electrical in nature, has nothing to do with the DPF/SCR performance, of course.

 

[dsl4me]

Just ran across this thread so jumping in late.
On the coal rolling, a properly deleted, tuned truck should not "roll coal". Even my non-turbo 6.2s under load, WOT, would just make a mild haze. You have to intentionally lug a M/T older truck to get it to smoke heavy and/or tweak the AFC, fuel plate etc. When the 2001 Duramax hit the showrooms and magazine tested it, was pointed out how it made clean power, w/o a DPF/EGR for the first few years.

Now, it's entirely possible these new trucks running 450/900+#s might have to have a DPF becuase they are turned up so much from the factory and would noticeably smoke without one.

Have been driving diesel pickups/cars for 30yrs now and, IMO, the coal roller crowd has done way more harm to our hobby than anything.

However, I do agree we have passed the point of diminishing returns with the most stringent diesel emission standards. To the point that the repair costs have caused UPS, MUNIs etc to switch over to gasoline in applications that used to be diesel.

 

[LouNY]

Emission controls are a farce anymore, when initially imposed they may have actually made a bit of sense. But like any governmental bureaucratic agency they seem to all get run and directed by zealots that have no practical sense. The initial regulations worked quite well and reduced the emissions emitted considerably. They drove engine manufactures to develop stronger and cleaner running engines. But the idiot bureaucratic twits kept tightening the screws until any tangible improvements have disappeared to be replaced with a continuing boondoggle of garbage that just increases cost and reduces reliability with minimal or no actual gains.
All the last couple of "tiers" has done is drive up costs, ruin efficiency and reliability. They have become bureaucratic "power" along with the loss of everything good.
They should be rolled back to at least 10 years ago and allow the current technologically to work as it should.

I had a 96 Dodge dually 1t (12valve) and boosted the injection pump a bit. If I stomped it, it would downshift and smoke pretty heavily. I added propane injection to it later and that rig burned so clean it was amazing. It took a bit to get the metering valve adjusted so it only began trickling when pulling a load or a hill and then control the max. I loved it! The automatic/OD transmission didn't appreciate it though.

The issue isn't whether the air should be clean. It's whether brainless extremists should be allowed to force half-baked, disastrous pollution-control measures on us way before the technology is ready. This is what they do, over and over.

I know this comment was a while ago, but to correct the record here - the EPA has mostly been technology agnostic. Meaning, they set pollutant emissions criteria, but they do not tell you how to get there. The manufacturers are the ones to select a technology and implement it on their engines in order to meet the emissions targets.

A perfect case study on this is Navistar - a former powerhouse engine manufacturer in the on-road trucking sector, their CEO insisted upon using super high rates of EGR to meet the NOx limits instead of adopting SCR (DEF injection) like everyone else. He was wrong, their technology failed, and now they barely exist (selling one Scania engine labeled as their own).
