200 MPG Carburetor Talk

[ChazInMT]

200 MPG carburetors! Ha, I love this one. Particularly since they were invariably tested on some sorta 72 Buick 225 sporting a 455Cid engine. Can you imagine the inefficiencies alone in drivetrain and aerodynamics that this magic carburetor would have to make up for?

Isn't there a particular Fuel/Air ratio that must be maintained in order for combustion to take place? This never seems to be questioned.

Then there is the specific energy of the Gasoline itself that must be considered, I mean is there really enough chemical power in that gallon to transport a big ol thing 200 Miles? Of course if we converted the matter to energy, it could take that car to Jupiter and back.

And then, knowing what we do today, the ability to get 70-80Mpg out of even a finely tuned machine with many parts engineered for efficiency alone, it is very difficult to achieve. Yet somehow, this one carburetor alone in a normal car makes all the difference.

Entirely possible. I you run a hybrid setup. I always wondered if gasoline heated to vapourisi g would work because that is he absolute finest mist possible

Ha, i had a teacher in high school claim to own such a thing. She claimed it was ford, and that ford had snuck a few out with out telling anyone. Had a long story about waiting in line during the gas crunch in the 70's, and getting yelled at by the attendant for being a "stupid woman" She waited in line after drving several hundred miles and only took just over a gallon of fuel. I doubted it as much then as i do now. Although...GM did try to kill the electric car, and succeded for a decade...

I'm sorry, I thought you meant 200 meters per gallon

Just take any carburetor and mount it on a.. bicycle?

I am afraid that the 200mpg carbs will join the dustbin of history in the quack section along with HHO devices made out of water filter containers.

Great post mpg!!!!

I agree, current gasoline engines are around 25% efficient so to make even a 50mpg car get 200mpg you would have to have it be perfect and produce no heat and to prove the point a bit more you can pretty much pick apart each part of a car and say how much fuel that part is using, how much air drag each part causes, how much friction loss you have, so there really are not big unknowns as to why a vehicle uses the amount of fuel that it does.

That last one looks suspiciously like an early constant velocity (CV) carb with a creative choke mechanism. Good stuff.

My wife's 89 Tercel had a CV (they called it variable venturi) carb in it, and got 55mpg when it was working right. Which almost never happened.
