I want to build a 100-mpg car (and I want it to look vintage)

I'm out. Have fun.

Yeah he got tired of the generally poop mileage, bought an econo box and promptly became a non driver. Afaik, pretty much mother earth news tractor mod with large diameter pipe in sloshing tank of gas. I wouldn't ride with him.

The replies have been insightful and informative. A reader can glean much information from all of this.

However, there is more to this than is found in both classical circles and pseudo science approaches. Raceprops does have a foot to stand on, though not in the way he is thinking.

Vapor combustion in and of itself is not the reason a gasoline engine can achieve increased efficiency ( within limits of total fuel energy). It is in the HOW that gasoline is vaporized.

Based on my father-in-law: if you never go above idle, it might be pretty efficient.

BUT There is a down side:

The making of these cars is horrible... and Driving them can also be bad: Once on the road, the carbon dioxide emissions of EVs depends on the power-generation fuel used to recharge its battery. If it comes mostly from coal-fired power plants, it will lead to about 15 ounces of carbon-dioxide for every mile it is driven—three ounces more than a similar gasoline-powered car. Even without reference to the source of electricity used for battery charging, if an EV is driven 50,000 miles over its lifetime, the huge initial emissions from its manufacture means the EV will actually have put more carbon-dioxide in the atmosphere than a similar-size gasoline-powered car driven the same number of miles.

A vapor car especially a older one if switched to pure vapor will be much cleaner that any HYBRID or pure battery power car.

Rich, in my car, the hybrid system was completely disabled. The battery was removed from the back. It's a conventional 3 cylinder gasoline powered car, with a manual transmission.

I've worked on vapor carbs that could propel a vehicle at normal road speeds with an increase of 50% mileage gains. But, they did lose the ability to accelerate to those speeds with any sort of alacrity.

Direct injection engines already fully vaporize fuel. Send the fuel through a sprayer at 2000psi, into a 5000F chamber, and I'd be shocked if any of it didn't vaporize.

I have see some reports of that so it would be to run on normal fuel feeding and switch to vapor for cruising, like a old two stage four barrel carb.

And yes the real nut is getting the heat to full vaporize current pump gasoline, the old, old vapor stuff was able to get white gas without all the junk in it.

And the temps need make vapor that will self light with just a hint of oxygen...

Cold vapor system can get the lighter elements but will leave behind sludge...

So it needs a air tight every hot system to make good vapor.

And no exhaust will NOT work as it drops like rock on vapor so you lose your heat and your vapor. until it heats up on normal system and you can go back on vapor...

Interesting, is it a diesel or Gas engine?? And can you beat a kid on a bike, and can you keep up with other cars on the freeway??

No it does not.

Not any more that dose a Carb, TBI, Port Injection, etc.

Try breathing the tail pip[e of one and see.

Even with the cats etc. it still stinks.
