Running on fumes....actually works!

[KI4UJO]

The problem everyone is having is believing the fuel is actually atomized when it comes out of the injector. No EFI systems truly atomize the fuel. They are just really small droplets of liquid. The high pressure direct injection systems make the finest droplets but it's still the heat and turbulence of the squish on the compression stroke that does most of the work to atomize the fuel but it's still not efficient.


As governments force engines to become even cleaner and more efficient I'm sure we'll even see direct injection fade away and all of the theories in this thread will eventually become reality.

Thank you, this is what I was trying to say/should have said. Fuel injectors spray small droplets, not vapor. I'll say this: It's amazing how breakthroughs tend not to occur until mandated by law. Just look at the Cali ZEV mandate. Manufacturers said the electric vehicles were impossible to build, and they built them anyway. I believe it will happen, eventually.

you both know that "atomize" literally means "small droplets," right?

I don't know what distinction you're making between "vapor" and "droplets" but this is not "new" technology you're discovering. You're simply reducing the amount of droplets that make it into your combustion chamber despite EFI systems' careful calculations of how much to inject.

I am aware of that. The distinction here is that atomized fuel never enters the engine with these systems. Only fumes, or vapor as it has been referred to here, is mixed with air and enters the motor. Liquid fuel never reaches the intake with these systems.

actually if you go deeper into the theory you will see that fuel is usually injected on to the back of a hot intake valve. there is a amount of time before the valve opens that you want to spray the fuel so it has time to evaporate and mix with the air coming down the manifold.

ding ding winner. This is why all those OEM;s running a Direct injection system on modern EGR engines are seeing big issues with carbon depositing on the back of the intake valves and head to valve mating surfaces causing lots of issues at very low mileages.

This "vaporizer" idea is not new in the least I remember reading about at least 15 years ago and was referencing shit from the 50's IIRC. Fuel is stable as a liquid, you want it to remain in the stable format as long you possibly can if you get a spark in your intake system or a small leak in the system you going to be asking for big trouble from the ambulance chasing lawyers....... Hint hint the DI engine carbon holding open intake valves with FIRE on one side....... I will let contemplate what might happen then.

Next as has been explained to you are still subject to the laws of thermodynamics, that it takes X amount of fuel containing X amount BTU to do a particular job. If it takes 3 gallons of Diesel fuel to get a load up a hill, its going to take at least 4 gallons of gas if both rigs have similar statistics Energy in = Energy out, and it takes a given amount of energy to do x amount of work

Thank you for bringing up the carbon deposit issue, this has proven to be an issue with mine.

At the end of the day, this technology definitely is not suited for the "real" world (yet). For now, I'll just use it to burn otherwise unusable fuel to mow my yard.

I have yet to find gas to stale for a lawn mower, or with too much 2 cycle oil in it for the chain saw, and I grew up on a farm. Dry gas is great for the water issue or a bottle of rubbing alcohol will do in a pinch for a dam B&S .............

While its a neat demonstration on theory and proof of concept, its cool that you built it for sure as buidling anything is great, and something that actually works is just icing on the cake. At the end of the day thats all it is neat, there are far more practical (and less explosive) safer ways to do it imo. Namely like pouring it in the lawn mower and yanking the rope..... Or using it to start a tire fire or something....

I have a jar of fuel that was pulled out of my dad's 74 vette after it sat for a year. It is the nastiest fuel that I have ever seen. The ethanol and gasoline separated, along with an additional layer of water. The closest the vette came to running was a large flame which was shot out of the Q-Jet. Also, the "gas" layer didn't even look like gasoline anymore. This is what I ran in the mower. The fuel was physically brown. I actually tried it before installing the vaporizer and was rewarded with nothing. I then installed the vaporizer the next day and mowed with the same fuel.

As for the explosive hazard, a flame arrestor (generally a mesh metal screen) is needed that a flame can not cross over into the vaporizer unit.

I apologize for any mis-spellings or incorrect terminology, I am tired.:yawn:

If you wake up from a late night at a party, save some money and grab the half empty bottles from around the house and pour them into your tank. You might have a bunch of lurching and chugging but its F*in genius. Lolz
