Re: Trucks about to get more expensive.

i don't know what they want myself. im all for cleaner air but i wish i could get the truth. i have been driving trucks for 30+ years and when they started screwing with the fuel the fuel milage went DOWN EVERY TIME. they have taken the sulfur content down 4 times that i can remember and the fuel milage has dropped 1/2 mpg every time so the way i figure it if i'm getting 6.5 in a road tractor now if i had good fuel i would be getting close to 9. another thing i would love to be able to get some good old number 3 fuel and see what would happen-- anothe r thing that i can guarantee is going to happen in a couple of years is there is going to be a critical nitrogen shortage due to the fact of all these diesels using it until they get the price where "they" want it

Re: Trucks about to get more expensive.

Nebfarmer, I have thought about the turbine, too. What has been a problem is how to get the most out of the engine,  and the real hold up has been a transmission, that would complement the turbine. Since Fendt developed the CVT transmission, I have thought that transmission would have been developed for more applications. I have been surprised they haven't adapted it in to combines, finally a combine that could actually put power to the wheels.

Re: Trucks about to get more expensive.

The turbine has a lot going for it, in particular its power to size/weight ratio.

The military uses turbine engines on the M1A1 Abrams tank, so we know it is rugged/reliable. 

Chrysler had turbine engines in cars in the late 60s or early 70s, testing them.  They had the problems of hot exhaust and noise solved, but they still had power lag (a delay from when you hit the gas, until the car accelerated) and were terrible on fuel mileage idling around.  Using a turbine to power a generator would solve this, as the engine would run only when the batteries needed a charge, and when running, could be put on a more or less constant load/RPM, where they are most efficient.  I don't know of anything that produces as much HP out of as small a package as a turbine, nor for the weight involved, either.


As to the combine with a CVT, I put a bunch of hours on an IH 715, with the belt drive to the wheels, and it would kill the engine before it would slip.  If I understand the Fendt system, it involves a CVT, with a powershift transmission, to provide pretty much infinite speed control.  Is that right?
