Is DEF that bad?

I'm going to drop this right here with all this talk about emissions.

My wife's uncle worked for the guy who took out a patent for the catalytic converter. The idea came to him because he was running the crematory in Philly where they disposed of indigents, and also the hospitals got rid of body parts.
The stench of burning bodies was so bad they needed to come up with a solution. It was the same basic technology that he put to use for car exhaust.

My wife's uncle and another guy did a lot of the testing. His boss bought a plane ticket for the suitcase that had the prototype and flew it and her uncle to CA for them to test it at Stanford if I remember correctly. His boss told not to take his eyes or his hands off that suitcase no matter what. When Stanford was done, they told him they really had something.

His boss ended up selling it to GM and GM put it in a Corvette to road test it. He and his co-worker then drove all over the eastern Shore of MD in a 1963 Corvette with a catalytic converter installed on it running tests. He was a young guy maybe early '30's, so to have a "job" riding around in a new Corvette was the ultimate.

And the rest as they say, is history.

Really makes you wonder if the forced EV revolution didn’t happen, and with the efficient new diesel technology, if we wouldn’t be looking at buying trucks with TWO diesel engine options.

Ram sort of does this with the standard output Cummins and ā€œHOā€œ Cummins.

Would be nice to have 2 distinctly different versions, but all this will be gone in 5 years and all out homes and every street corner will be a charging station (powered by solar panels, of course)

BTW: Did anyone see the report last week that the largest EV charging station in the country was powered by diesel engines?

Bet they have a DPF with DEF on that 50kw generator....

I think the interesting part of my wife's uncle's story was that GM had the technology and knew it worked in 1963. But didn't use it until 1975-76??

You can't use a catalytic converter with leaded gas; it had to wait for large-scale switch to unleaded. Probably had a lot to do with the delay.

That could be.
12-13 years is a quite a long time.

Lots of DPF problems are a result of operator error on tractors- not knowing they need to be run at higher RPMs, or on trucks, not running them long enough & hard enough to get the DPF real hot.

My mini x has an an automatic idle setting that will drop the rpm to idle with a few seconds of inactivity on the controls and returns to operating rpm as soon as you touch the controls. Do they want you to have problems or is idling not actually that bad? It seems to me that if rpm was of critical importance they would do away with operator controlled throttle and let the machine set itself.

I don’t think idling is the problem and never said it was.
It’s working with the RPM too low that’s the problem. Some call it ā€œluggingā€. Not enough heat is made to burn off accumulated soot at lower RPM.

Then there's this.
I felt a little better 20 minutes ago reading the above post, slid over to YouTube for a little and this popped up. 🄺

I read some horror stories about DEF and DPF issues on some tractors. I think some companies have it figured out and some don't. Which are which I don't know but I do know that JD pretty much has it figured out. It's like falling off a rock. You just leave the switch on and don't do anything. I've had my 5090 for 3 years and no issues. I do run the idle a bit higher but I'm not afraid to idle it down. As Hay Dude said, most of the issues that I have read about are operator intervention errors and the lack of understanding of the system. This stuff has actually been around for a very long time in all parts of industry.
