I hear a concrete mixer starting up..
We do civil discussions here.
Pretty sure there is a line that has been crossed here.
We shall name him Short Time.

Hey friend! Could I invite you to check out this thread over here: https://grassrootsmotorsports.com/forum/off-topic-discussion/forum-rules-welcome-to-the-party/104340/page1/
Thanks!
To stay on-topic: Belching smoke bad. Systems to clean up smoke are complicated and expensive. And to beat my own personal dead horse, screw Mercedes and their bluetec system.
In reply to volvoclearinghouse :
Agreed. We live in interesting times.
So is there any real "solution" to diesels? They make a ton of torque and are more efficient, but they pollute and even with modern technologies it seems they're still putting out some nasty stuff. Other than for towing/hauling, they kinda seem like something that should basically be phased out. I hate that I'm saying that.
Also I need to watch out. I may need a bodyguard. I'm getting cat delete pipes for my Mustang and I don't want someone to put a bullet in the back of my head because of it. Scary thoughts.

The new 7.3 does not have variable displacement... At least that I know of....
My mistake then...I thought I'd read that it did. Or perhaps just assumed as much.
EDIT:
This is what I read. Again, I mentally must have filed this under "cylinder deactivation":
"Details on a special fuel-saving calibration will be announced later this year. "
Any bets on what an F250 crew cab short bed 4x4 with the 10 speed trans might get on the EPA highway cycle with this engine? If it can pull off low-mid teens that would be pretty impressive.

Hmm. What else makes a ton of torque and is super efficient....

Modern diesels are a tool. Like all tools they are designed to do certain, specific tasks. And like any tool they can be misused, and they can be the wrong tool for the job at hand. They're designed to work, and spend most of their time under load. It's the wrong tool for the job if they won't be under load often. They don't work well for commuters, or people that spend lots of time at low load/idle conditions. They're the right tool for the job if moving heavy stuff is mission critical.

Who knows, they may someday- given the same general valve train as the GM that has it. But for now....

So, you can surely see that there's a massive incentive to solve that problem. Huge and massive incentive.
If anyone here can come up with some good ideas that we've not thought of, you will be well compensated for that solution.

I assume that at some point, someone thought about marrying the diesel engine in a semi to a generator and then wiring up some electric motors at the wheels like a locomotive or a ship, yeah? What makes that a bad idea? Packaging problems? Not enough constant torque demand?

EPA is much like any other agency. Power and control are their mandates.
LOL- you should try working with them sometime. You will know that you are not correct. If you are in an industry who is not willing to come to the table, yes, it will seem very draconian. On the other hand, if you understand that the rules are always a two way street, and have a good working relationship with the agency in question, they are very happy to work with you.
Mind you, I very much benefit for when cars become less expensive to make. There are a couple of us here who have actual skin in the game, but I don't think any of us are nearly as dark to the EPA nor CARB as others here on the board.
Again, if you want to waste your energy hating the wrong people for the wrong things- it's your energy. I'd suggest it's not a good idea.

I'm sure they have, too. Probably cost is the big problem. Especially the projected benefit for the nominal duty cycle.
There are hybrid diesel busses, and my home city (Ann Arbor) has had them for over a decade, and it's time to replace them. And even though A2 is one of the most "left" leaning cities in the world, I really don't see them geting them again- even though the bus duty cycle is very much in tune with what a hybrid system should offer. I'm not sure of the entire details, but they are not yet worth it. (although, I do wonder if they went to F1 style 1000V batteries they would be more effective....)
alfadriver, you need to be careful talking like that. Some of these EPA hitmen might shoot you. It's super serious stuff, I'm living in fear every day now. I just hope no one finds out I also tore the tag off a pillow.
But yeah back to diesels, volvoclearinghouse you have a good point on the electric motors. My wife has a plug in Prius and that thing is great. I believe the electric motor is only 50hp or so but it's got all it's power from basically 0RPM so it pulls pretty well from a stop. I've read that Tesla's new roadster is supposed to have massive amounts of torque, enough to do sub-2 second 0-60 runs. It's battery is also just over 1800lbs and it has a range of over 600 miles. I know heavy towing would burn through the battery a lot more quickly but certainly a truck the size of an F350 dually would have the space for a 2,500lb battery (instead of all the ICE stuff) so perhaps it could still tow similar amounts and have a 500-600 mile range. Of course the issue there would be charging a battery that massive in a short amount of time. Given enough time I'm sure technology will have some solutions.
The EPA's budget should be zeroed out until the whole worthless agency is starved out of existence.
The malicious and politicized bureaucrats who make up the bulk of the workforce should be forced to toil along in menial jobs until they retire or leave the government entirely. The EPA is so harmful to the United States it might as well be an arm of a hostile foreign government. Since its inception, the EPA has cost trillions of dollars in efficiency and production, vaused billions of dollars in environmental damage THEMSELVES (https://www.newsweek.com/epa-causes-massive-colorado-spill-1-million-gallons-mining-waste-turns-river-361019) , and eradicated or prevented the creation of millions of jobs.
Even if one were to take for granted that there was a need for a Federal EPA in past decades, it is undeniable that the EPA has morphed into a punitive and partisan agency ( https://www.ifrahlaw.com/crime-in-the-suites/judge-awards-1-7-million-in-epa-malicious-prosecution-case/) (https://www.forbes.com/sites/markhendrickson/2013/03/14/the-epa-the-worst-of-many-rogue-federal-agencies/#40bdbe3721ad). Gasoline engines of today, are many many manty times cleaner than what they were 40 years ago - yet, instead of the EPA letting automakers have some breathing room, it further constricts their ability to produce gasoline vehicles - continually putting more and more restrictive regulations on emissions. Engines of today produce a small fraction of the pollution they did years ago, yet the EPA mandated regulations get stricter and stricer - in perverted and punitive logic on a central planner would appreciate or understand.
Unfortunately, the typical useful idiot hears "environmental protection agency' and thinks that it must be a worthwhile organization. When in reality, the EPA is staffed to the gills with true believer leftists who think that the internal combustion engine is a threat to the sruvival or mankind.
The automakers need to marshal their forces and fight back against this out of control, weaponized, hyperpartisan federal agency.

Hurrr-durrr. wait till the EPA fines you out of your own shiny happy person because your car set off one of thier 'mobile detection' stations.

No comrade - it sucks to be you. I love my family and my existence, thats why I am so keen on protecting it from the likes of you and the types that manipulate you into assailing our quality of life.

Cost and weight are the biggest detriments to that setup. Over the road trucks are very sensitive to weight since they're limited to 80k lbs. If you add a few hundred lbs of battery and motors to the tractor, that means you can't haul as much freight.
