Since many folks tow their heavy toy haulers and fifth wheel trailers with HDT or MDT trucks this article may be of interest to you. A quote from the article.

"This is especially important because heavy-duty vehicles are a particular concern when it comes to pollution. Diesel engines, more commonly found in such vehicles, create greater amounts of nitrogen oxides (or NOx) than conventional gas-powered engines do. This compound reacts with other chemicals in the air to create pollution that can cause a variety of respiratory diseases, like asthma."

Cheers and Happy travels

The 3406E ...

One of my favorite engines! They purred going down the road.

One thing about political agendas, they are always open to change as needed. Seems very unlikely that 2027 is carved in stone. When they see the goalposts can't be reached, they simply move the goalposts.

And you actually replied once in your own poop slinging thread! Wow! This is progress. I’m happy for you.
Have you quit with the tagline saying you dropped a turd and won’t be returning for comment?

Key word is year 2027. Not that far away. Prepare for the future but many get caught flat footed. Not me. I am a happy gasser. Cheers to the open minded.

One issue is that for Commerical class 8 trucks etc, the useable life of the engine is often decades so it takes a long time to get them out of service.

Maybe an old farm truck that sits except at harvest time.

Semis that put on lots of miles are usually good for 10-15yrs. Yes, you can keep refurbishing them but usually not financially viable.

So not drastically different from cars.

The "service life" of OTR engines can very a lot depending on changes in engine technology. Example, late 60s, early 70s dealers where selling about 10% glider kits so buyer could use old engine, trans and rearends with new cab and front axle. (I ran the engine number on my last 1693 Cat, found the 76 Pete was the 3rd truck it was in) Then oil embargo forced engine manufactures to re-design, improve the efficiency of engines. For decades few kits sold, because engines where improving, new truck buyers wanted the more efficient engines. Then there was a spell where emission regulation hurting the availability of some engines, and more importantly the dependability of the engine. (Shipper don't care if load was late because turbo exploded or the emission system shut it down. The load was late is only concern) So some companies are buying kits, using old engines. (The 3406E out of the 95 Pete I sold in 13 is in a Western Star kit from 2016.)

current trucks with DEF have very very very low NOX emissions, that's the whole purpose of the DEF. BTW DEF is also used on huge power plants and other applications to convert NOX to N2 and H2O.

Lol, not sure what the “news” is….so there’s a stricter epa nox limit in the pipeline?
Great, I guess the warning is “buy a truck now or keep your old one fixed up because stricter emissions is certainly not gonna be cheaper on the consumers pocketbook.”

While "OLD" news in my book! Tis has been going on for the last 40 years I've been driving diesel rigs of ALL sorts. Even in gas rigs this is going on.
Honda recently decided to quit manufacturing gas mowers for the residential/commercial market because of emission laws going into effect. Tiy can still get a generator/weed eater/ or equal gas 4 stroke from them. No! lawn mowers anymore!
I've been running commercial Honda 21" walk behinds for 30 some odd years!
Also, why pickups have cats and equal on the diesel engines etc. just like gaz pickups etc. Then again, if my Navistar has a blow out of its IDI 7.3......not sure what I would replace it with......might stick with it, as its old enough I at this point in time, do not have to upgrade the emissions part of it. I'm sure it will not meet current standards.

It only took me 5 or 6 times to remember how to make the link a clicky! That is the only edit I did to NamMedics post.
