Meets 2010 emissions and an ultra-low .279 bsfc, translates to 50% efficiency. Most engines nowadays are around 40% efficient.

Meets 2010 emissions and can easily get 8+ mpg.

I want.

To qualify that bsfc, bsfc is described as the amount of fuel, in lbs, it takes to make one horsepower for one hour. Typical gas engines are around .4-.45 and diesels are around .3-.35. Lower is better.

Say it takes 200 hp to push our rigs down the road, let's do a little math here, assume that diesel weighs 7 lbs a gallon:

at 65 mph, using 200 hp, that requires 55.8 lbs of fuel for an hour. 200 X .279 = 55.8 lbs of fuel. 55.8 / 7 = 7.97 gallons. 65 miles / 7.97 gallons = 8.15 MPG.

[allan5oh]

my calcs are a little off, 7.1 lbs per gallon.

8.28 MPG at 65 mph.

Now *THIS* gets me horneyTry coming off the road for a while. Good luck.

if tomorrows engines got 20mpg, then tomorrows loads would pay half the amount, everything is always proportional, at the end of the year you would make the same money, so if we start paying$5 for diesel then shippers pay more for load and again the bottom line is that you would make the same money.

That's if all the trucks get the exact same fuel mileage as you do.

Right now, fuel mileage keeps dropping with every new emissions standard coming out.

The best thing to do right now is get a pre 2003 truck that gets 8+ mpg, and hold on to it in 10-15 years. You should be able to retire by that time!

The average truck right now gets about 6 mpg. Assuming 120,000 miles a year, the 8 mpg average truck will use 5,000 less gallons of fuel.

Over 10 years, thats $150,000 at $3 a gallon.

That's a LOT of coin.

I never again want to read another man state that this gets him horny. I have to go put some bleach in my eyes.

Jumbo, I'm with you on this one,....I was afraid to even open the thread.
If your going to mention horny on a truckers forum, you will be required from this moment on to at least post pic's of a scantily clad bikini model (female please),....or suffer the consequences,.....now pardon me while I go get the bleach :shock:

[fruitloop]

wow this topic got my attention.. hmm think I better get my mind else where

[Doghouse]

Yeah,...not what I expected either

[fruitloop]

yeah.,..that goes to show what we were thinking :wink:

[Doghouse]

I try to focus on world hunger, global peace, and how to keep from spilling my cereal while I drive, it often takes much of my time when I think of the homeless people and orphaned children, and wonder to myself?????? :?
(((pauses a moment before mind veers off into the gutter again)))
I wonder how a woman would look covered in whipped cream??...............
even if she is homeless.

Exactly. And your total truck expenses keeping it on the road would not be a nickel more than any other way and cheaper than many ways.

Sorry guys, got pretty excited about this. I thought about this idea about 2 years ago. I never knew someone was actually thinking it out.

What's incredible about this, is how it can be mated to a hybrid drivetrain.

Also, it claims a 15% increase in horsepower, for free.

Imagine going up a hill with 15% more horsepower, and knowing you're not using a drop more of fuel.[/i]

[brian]

my old long hood gets better mileage then most if not all the new aero trucks out there anyways, and my kw isn`t gonna fall apart either.

Allan,
Now you have me excited (not horny), I like to see new technology and it would be nice if there was a viable way to improve our mileage.
Soon enough they will probably have some type of hybrid system for class 8 trucks. But the system would probably weigh 2 to 3 thousand lbs.
It makes the most sense in trucks to assist on hills and starting up from a stand still (short bursts of stored electrical energy) and can you imagine the regenerative braking capabilities of an 80,000lb vehicle,...the new engine brake!
I'll be watching this technology to see where it goes.
I drove a prius from Flagstaff to Sedona down through Oak Creek Canyon, and never touched the brakes once, the batteries were low when I started and fully charged by the time I reached level ground.

[allan5oh]

Unfortunately that type of hybrid system isn't very viable for a big truck.

The reason is simple, we drive mostly steady state on flat surfaces.

Batteries couldn't store enough energy to absorb momentum like you did in the prius.

However, where it would be very good is when it's coupled with a system like this. Now steady state you increase MPG considerably.

You wouldn't need substantial batteries.

You could get away with a 9-10 litre engine.

Now here's the most incredible part, you could do away with the transmission and go with a series hybrid system like the prius. That alone would save 600+ lbs.

As you can see, the transmission is nothing but a "power split device", a sun-planetary gear setup. Extremely strong. Essentially a CVT.

Now there will be those that say there will be losses between MG1 and MG2(MG1 controls how much the engine is allowed to rev) but what you can do is get some type of "lock up" device for steady state cruise. Much less losses then our traditional twin-countershaft transmission.
