Ok so the engine heats the gasoline to about 400-440F and vaporizes the gas more properly causing better fuel/air mixture and a bigger boom. where does this leave this? much more mpg and hp! this "claimed" hot vapor engine running in a fiero gets 250 hp 230 tq and 51 mpg its 0 to 60 time is less then 6 seconds. I am personally very skeptical about this but I'm very curious at the same time. anyone ever hear about this thing?

*edit* I made a mistake. There isn't a "bigger boom."

How this really works lies in how gas ignites. We all know gas ignites in it's vapors and not the liquid itself. this being said cold gas is more dense and thus doesnt vaporizes as well as it could. Cold gas only uses about 25 percent of its potential, and by adding the heat the gas "correctly" vaporizes using 100% of its potential thus cause a less wasteful cleaner burn and using far less fuel and producing far more hp. As a base line, you get close to 1.8 hp per cubic inch. I am still very skeptical on the smokey's hot vapor engine design i have found, but i did find a gm 4.8l v8 running on vapors using a entirely different design. From the looks of it he is heating the gas directly in the tank and channeling the fumes directly to the engine with no injectors and no fuel pump.

Wouldn't that cause detonation on the compression stroke? Essentally that is how a diesel engine works heats it up from compression until the point where it self ignites. But on a gas motor with spark plugs that seems like a bad idea. They actually sell fuel line coolers for carbarated motors so why would you want it hot?

 

Here is what I found on it. I think if Smokey Yunick had anything to do with it it must be real. Smokey Yunick’s Hot Vapor Fiero; 51 mpg and 0-60 in less than 6 Seconds! See and hear it run in our exclusive VIDEO! : Legendary Collector Cars

 

I don't see how that is more efficient than what we have now, gas has a extreemly low flash point thus why we store it in sealed containers, such as the gas tank becuase gas will evaporate if it was not,

Gasoline has the dangerous combination of a low flash point combined with a high vapor density. The flash point of a liquid is defined as the temperature above which the liquid produces vapors which can ignite or explode. The flash point of gasoline is - 45 degrees F ( - 43 degrees C). In practical terms, this means that at all temperatures above minus 45 degrees, liquid gasoline is producing vapor which can ignite or explode. By comparison, the flash point of kerosene is 100 degrees F and the flash point of diesel fuel is 125 degrees F.

 

I keep one of those red gasoline cans in my shed for the lawn mower. I know that on warm to hot days, the gas starts to vaporize inside the sealed container, and the container starts bulging. I have to unscrew the cap to let the pressure out.

Seems to me you would have a serious issue if your car pre-heated up gasoline to 440 degrees.

 

to the above post this is why i believe the motor wasnt put into production because of the risk of explosive decompression, and engine fires

 

I would think you would also get a very bad case of vapor lock, particularly since gas vaporizes so easily.. But I could be wrong on this..
