thundair,
The contest is for 100 MPGequivalent, meaning that the thermal values of the fuels are taken into account relative to gasoline and there are corrected (and different) MPG values for fuels other than gasoline.
Someone already thought of that..
I wish it were that simple but there is a problem with doing that.
In RDH4 the author uses 12 ohms for the twin 20AWG ohms/1000ft.
But 20AWG wire resistance is 10.15ohms/1000 ft.,
21AWG wire resistance is 12.80ohm/1000ft.
12 ohms is way over the number for...
I'm forwarding this from a tube amp board because no one there can figure out the answer, I've had no luck at the library either so I thought maybe you guys could lend a hand:
Hi all,
Does anybody know where I can get a wire table for twin wire?
I'm going to wind a PT and I have a bunch of...
I'm fairly sure they're talking about an obscure engine design that I'm familiar with. It was invented in America (so far as I know) and patented as 1,095,190. It was re-invented in Canada by John Nowakowski (patent search at the Canadian office will turn that up) and has come up again a few...
Do you think exiting the exhaust above and behind the cab like a Semi-truck does may help? My father built a diesel truck like this and most of the exhaust clouds well above your head that way.
I've thought of using water injection to gain power from the subsequent vacuum (some early steam engines operated on this principle) but when you do that with an engine you effectively ruin your means for getting rid of CO and NOx emissions. The catalytic converter only works with a lot of heat.
People have been experiementing with CVTs in bikes for a while.
One example (I'm not affilliated):

Seems like that one is a toroid, though I can't be sure.
Bio-fuels reduce nearly all harmful emissions and almost totally eliminate SOx as well as particulates, that isn't minor. Beside that the process of growing the crop recycles more CO2 than is emitted. It won't endanger our food supply because there are so many farmers letting parts of their...
Emissions are lots better than petro-diesel with the exception of NOx. I've read that people have reduced the NOx emissions to lower than petro-diesel emissions by adjusting the engine timing. Here is what the EPA has to say about it:

Actually Bio-diesel (vegetable oil product) can be used without modification in diesel engines. I could see it taking over rather than ethanol, or perhaps with ethanol. I believe that some fuel lines are vulnerable and engines which have used diesel for some time will see dirty oil as the grime...
You seem to be missing a very valid point Hydro.. when you make Hydrogen it is either made cheaply with fossil fuels or expensively with clean electricity. How many square miles of windmills and solar collectors do you think it'd take to produce the required electricity to split water into...
I've been under the impression that Diesel engines are manufactured to closer tolerances and with thicker cylinder walls to account for the higher compression ratios, which is what makes them so much more expensive than gasoline engines. I'd imagine that racing engines are the same.
Regarding emissions.. If Bourke claimed the only emissions were CO2 and H20 then my thoughts are that he was using ethanol as a fuel. A conflict is that ethanol is a high octane fuel and somewhere in this huge thread I read that the engine needs a low octane. I could only conclude that he was...
What kind of metal is most resiliant to the type of friction a piston is known to encounter? I've heard of deep chrome plating before, is that the most preferable option? Will I be able to get aluminum electroplated with it?
