DEF going away ?

[Torvy]

Who's making them for what countries?

Most of the big automakers have already committed to keep making their vehicles meet the CA standards.

They aren't going to change production over a temporary reprieve in policy.

I'm all for changing the policy in a permanent way. If they do that, automakers will be happy to save money.

Eliminate the CAFE completely. Let buyers choose. Part of the reason we can't buy the Hilux in the US is because of our convoluted standards.

Disclaimer: I do not own a diesel truck, and potentially never will. So I truly cannot feel your pain. However, I do own a diesel tractor and the DPF gave me issues, I have since rectified that problem.

I get what you are saying about the emission controls on a diesel truck being a PITA for diesel truck owners, but it is a slippery slope. You obviously have not spent time in a place that is completely devoid of such emissions controls. I lived in Medellin, Colombia for 2 years. Every city bus and delivery truck belches out thick diesel exhaust as it goes down the road. Air quality in the city is abysmal. I also lived in the foothills of the Indian Himalayas for a year. They have something called the winter line there. Instead of setting behind the true horizon the sun sets behind a layer of pollution that hangs in the valley below. Getting rid of all emission controls on all diesel vehicles WILL negatively impact air quality in lots of places. I am fully aware which team you are on when it comes to matters like this, but you gotta see the bigger picture.

All I know is that everytime I see some idiot who has removed all of the emissions controls from their diesel trucks and programed their truck to "roll coal" it pisses me off. You northern brethren might not see it as much but I see it often here in the south. I couldn't imagine if every diesel going down the road did that.

Out of curiosity. How did you rectify the problem on your diesel tractor?

What gets lost in all of this discussion on diesel emissions is that just a bare diesel engine today, runs cleaner than the similar diesel engine did 20 years ago. There are a few diesel engines produced today, that run clean enough to circumvent having to have diesel emissions equipment on them.
In my opinion, I would not completely eliminate diesel emissions, regulations, but would ease them back to a more reasonable level.

.

I’ve seen videos of train shipments of John deer equipment and Ford trucks being shipped to Mexico with straight piped exhaust. The military isn’t buying emissions equipment either.

So Uncle Don just took a axe to the CAFE regulations for autos and light trucks.. Long over due... But it's ending. Will that get rid of the nonsense of EGR valved and DPF on diesels in the next year or two ?

No.

The answer is no. At least, not yet. They can wipe out the CAFE fuel-economy standards, and remove the 2008 endangerment finding (that CO2 is a pollutant), but any attempt to roll back the actual tailpipe emissions standards will be met with a wall of legal challenges and will have a court-ordered stay (keep current rules) during the process.

So for now, your taipipe NOx, VOC and particulate emissions standards will not be reduced - meaning, you still need DEF and EGR to treat the NOx, and a DPF to catch the particulates. This is a good thing, though. The technology is robust and effective, and keeps our ground-level air much cleaner (especially in urban environments).

A large drill bit.
