OTR rigs are going to change

Didn't want to hijack the jet thread so posting this link in a new one.

The jet thread is about a carbon fiber airplane that is much lighter than a plane made mostly of metal. This new rig is also much lighter becuase Great Dane is building a carbon fiber trailer and saving 4,000 pounds. The Peterbilt tractor is really stunning.

I hope the link posts right and that it works...

When carbon fibre first came out it was supposed to be some miracle material good for everything . Then they made brake rotors out of it and got alot of guys killed.
 
By the time that the federales (especially, though not exclusively, the EPA) are finished (of course, federales are never finished) destroying yet another US industry, expect a great deal of US continental freight to be shipped by foreign owned (and staffed) marine shippers both on the continental waterways and ocean-going from costal city to costal city.

You will also see a resurgance of rail freight traffic until the federales decide to take aim at remaining US railroads.

You doubt?

Stay tuned.

1000, 2000, 3000 page bills packed full of hidden stuff that NOT one of them reads before they vote "YES" for them? Nahhhhhhh. Nothing bad could possibly come out of that. Hasn't so far, has it?

(quoted from post at 13:52:42 06/13/15) I saw the Feds want a 40% mileage increase by 2020.

Feds can pass what ever law they want. Even the government can't change the laws of physics. Diesel fuel still only has 128,480 btu and 40 ton still weighs 40 ton.
 
I'm glad I got out of trucking aboot 25 years ago, there was more independence than there is now.
Back then it took fortitude to be a truck driver, no power steering, no air ride suspension or seats, no air conditioners, not very good heaters, two lane highways, transmissions that had to be double clutched, police had radar hanging in trees and some states such as Virginia, Wisconsin 45 mph for trucks.
Now days anyone could drive a truck, it takes no more effort than driving an automobile.
 
You may be a little bit off Dean.

Lots of things are being done behind the scenes to combat large scale trucking problems.

Such as some argue that 1 cu ft of freight moves per gallon is better than 0.5 cu ft of freight moved per gallon even though the truck gets the same or worse mpg.
The company I work for is lobbying the government right now for 32 ft long trailers to be used in double rigs nationwide because we haul a lot of high cube light freight.

In short the government can push the trucking industry as hard as it wants.
Let it cross the threshold that effects John Q Public's over night or just in time freight system and that government will be committing political suicide.
Trains and boats can not offer this just in time service.
 
Since we're talking about fuel economy, I'm wondering when all the manufacturers of pickup trucks today will get out of their obsessed competition with building the pickups with the biggest, brawniest, most massive block-like front ends ever. They've got to be aerodynamic disasters with their enormous battering-ram front ends having to push that much air out of the way traveling down the highway at 70MPH. Maybe they need to ask Kenworth and Peterbilt how to make low profile front ends with sloped hoods. And why do the pickup manufacturers have to build pickups that are so tall you almost need a ladder to get up inside them? Even the half tons.
 
Thanks for posting. That was the best... never seen an "all rust" semi tractor and trailer/tanker.

I like REO and Brockway trucks too. Even old grain trucks like Dodge and Chevy.

Have to google Autocar - don't know what it is.
 
Just plain ridiculous looking and downright UGLY with CAPITAL LETTERS. I can see some backlash coming from some of them. Like how about the electronics end of things. How about when backing, now you have TWO blind sides. It becomes obvious that the designers are running out of ideas. You can only do so much with the "modern" looks.

As to a 40% increase in fuel mileage, I can only say that B&D said it right. There are only so many BTUs in diesel fuel, and 40 tons still weighs 40 tons. They can pass laws demanding anything that they want, but in reality, some things can only be complied with to a limited extent. Let me see..... since the typical "old school" trucks only got about 4 to 5 mpg of diesel, and the newer trucks nave gotten that up into the 7 mpg range, a 40% increase would put that into about the 11 mpg range. I get about 7 to 9 with my antique car, about 14 with my SUV, and mid 20s with my car. Asking for 11 from a vehicle that weighs about 15 times as much as my car, 10 times as much as my SUV seems unattainable. Leave it to politicians to ask for the ridiculous and unreasonable.
 
Diesel fuel only has 128,480 btu's this is true but we have a long way to go to turn most of those btu's in to mechanical energy. Expect more electronics and computers in everything that burns fuel.
 

Try as you may but you can not make a Tier IV open loop Brayton Cycle diesel do better than 20-21 HP per gallon per hour at full power.And that is really stretching the limits. 16-18 HP per gallon per gallon per hour is more realistic.
The very best on can squeeze from diesel engine in a combined cycle application is around 50% efficiency. In applications as electrical power generation or ship propulsion.
Just not going to do better. The absolute max that can be extracted from a gallon of diesel over an hour is 25-26HP. That is it and all.
 
Well great. The little Cummins B3.3 (L) NA in my Branson is rated, and I have proven it, at .046 gph/hp used which works out to 21.67
hp/US gal when running at rated power under load. Not too bad.
 
They started making funny car bodies out of it too. One driver had an engine failure and the resins in the carbon fiber burned, the fumes almost killed him. He refused to run carbon fiber after that.
 
Jimmy Adamo killed in the Daytona 200 when his carbon fibre rotors failed leaving him brakeless and slammed into haybails .
 
I have one unscientific real world example of how much of a load one gallon of diesel fuel will pull no matter what the vehicle or engine. Wheat harvest again! We had two header trailers that would hold two 40' MacDon headers apiece. We pulled one with a late 80's International day cab semi with a mechanical 350 or 365, I forget, Cummins and a nine speed. The other trailer was pulled with an 04 or 05 Chevy one ton dually with a Duramax. Those headers on the trailers were a wind resistance disaster, they pulled hard though they weren't heavy. Both the truck with the Cummins 350 and the chevy with the Duramax ran neck and neck for ability to pull those trailers, both had their toungues hanging out pretty much full time to sustain 60 MPH IF they could get up to 60 MPH with the pedal to the metal. Both the truck and the pickup got about the same mileage, around 6MPG. I drove both of them for long distances at one time or another. The advantage to the truck was the big fuel tanks. Once a day for fuel for the truck where the pickup was constantly stopping for fuel with that little 30+ gallon fuel tank. The other trucks with bigger engines hauling combines could pull away from us on the long slopes.
 

Re-check your math. The numbers don't jive.
How do you know that the tractor was making rated power? We see a lot of people here post that their 50HP tractor used two gallon an hour while making 50HP clipping pasture fields. Then they think their tractor has exceptional fuel efficiency. In reality the engine was making 25-30HP average over the hour.

The fuel mileage increases will come by getting CAFE credits not the actual MPG... They may reach there goal by credits along and only achieve a modest increase in MPG.

A example would be by switching to new refrigerant (R1234YF) they would receive a 7 to 8% credit on MPG even tho it does not increase MPG... Any thing they can do to reduce weight would apply to CAFE fuel credits..
