Q:
Well you know what they say about opinions
. I think it will work on a very limited range of RPMs in its current design, however your upgrades may open that up. The benefits to its original test equipment was that it was a gasoline engine that had 6.8:1 compression, originally leaded gas, and limited heat production. It was basically a tractor engine that could run on kerosene, gasoline, or moonshine. Today's engines have a much more stringent requirement for mixtures and airflow. Have you picked an engine on which to test yet? A two stroke engine like an outboard or dirt bike engine might provide a simple basis with some metering flexibility. Fine tune it on something like that or a Briggs first and it might help you hone in on metering.
I think you could braze aluminum pretty easily, but I don't see any problem with copper.
I don't think you'll have any problems. Plus, how sweet would it look to have a polished copper carb under your hood!! I'm anxious to see it.
A:
Yeah polished copper is nice, I use copper alot in the humidors I build.
A:
My car has a 1980 Pontiac in line 4 cylindre, 2.5 litre, 151. The compression ratio is 8.3:1, but I'd say it's closer to 7:1 by now. That' close enough.
As for the gas, I just happen to know an airplane mechanic, who can help me get a good deal on airplane gas, which I believe is around 104 octane, and leaded.
I've tried to braze aluminum before; it doesn't work very well. That doesn't really matter, though, since I will be using no aluminum in this carb. I agree with 'TheSilentChamber' that copper is nicer looking than aluminum.
As for poor performance, I wouldn't be surprised if my car has better performance than it does now.
Here's Pogue's theory in a nutshell:
Conventional carbs drip liquid gasoline into a turbulent airflow, which is sucked immediately into the cylindre, and fired. When fired, the gas vapor explodes, in a nice clean, cool, explosion. Droplets of liquid gas form inside the cylinder walls, and on top of the piston, and eventually flame, producing a lot of heat, and not much power, while burning quite a bit of extra gas. (This was written in 1933, but that is what even the latest carbs, and, yes, fuel injectors, do.)
Pogue's carb prevents any liquid gasoline from entering the cylindre. The carb, instead of dripping or squirting liquid gasoline into the intake, or misting gasoline directly into the cylindre, vaporises the gasoline, through atomisation, heat, and aeration of heated liquid gasoline, with heated outside air, then feeds the vapor into the intake.
This results in a more clean-burning engine, better engine performance, cooler-running engine, longer wearing engine, and far less gasoline comsumption.
That's what he said, not me. But I am inclined to believe it, not only because the theory makes perfect sense, but because Pogue was bought out almost as soon as he started producing these carbs. Not another Pogue carb was ever produced, but he did go from an almost broke inventor trying to sell these carbs, to a wealthy filter factory owner in the space of a week. I don't think it was because he won a lottery.
By the way, I met a guy who actually built a water electrolysis carburetor for his car. Curtis, you were right: The explosion does produce water, and the guy that I talked to, said, that it turned into one of those 'new engine every few thousand miles' deals. I would rather buy gas than a new engine. I suppose the only way to get it to work, would be to build every piece of the engine, out of rust-proof metals, and try to figure out a way to keep the water from seeping past the rings. Even then, I figure you would have to use synthetic oils.
Just a thought.

A:
Goodluck. After that, maybe you could make me a perpetual motion machine, becasue this "running on water" thing is basically the same concept. Water, split into H2 and o2, then combusted back with each other = water, yet there's a net gain in energy? I don't think so.
A:
Steel... we're not talking about the water carb anymore. We're talking about Pogue's carb which basically evaporates gasoline before mixing it with air... the water was a different discussion.

hey lets all write in bold and huge letters so we can dominate the whole net window...
