Congratulations. He just re-invented the carburetor.

He just re-invented the carburetor.

Yeah, looks like a bulky side-draft carb.

Doesn't a carburetor make a fine mist of gasoline, rather than a gas as in this video?

[–] • 4 pts

That doesn't make any difference. You can run gasoline motors also on natural gas.

[–] • 2 pts

not by just hooking up a gas bottle to a fuel line you cant, its a bit more complicated than that.

LPG and natural gas are not interchangable, and an LPG conversion requires a lot of work to remove stuff that the LPG degrades.

dual fuel LPG cars here are specifically built to run both.

He didn't think it would work either.

To be fair he's lucky it didn't explode.

Gasoline engines always run on vapor, that's how they work.

[–] • 2 pts

I think they normally run on a mist (fine droplets) not a vapor (gas).

[–] • 2 pts

They run on a gas. That's why they a choke. When the engine is cold the fuel doesn't vaporize, so you need a higher fuel/air mixture. Once the engine is warm enough the fuel droplets from the carburetor/injection are vaporized in the intake and so the air/fuel mixture can be turned down. Direct injection engines vaporize the fuel in the cylinder itself. Direct injection engines have to modify the injection pattern when the engine is cold.

Ahhh. Someone else said that the approach in the video is basically a high air-fuel ratio mode of running, which agrees with your model where more fuel is required when its surface area will be lower (when cold and it's not vaporizing the droplets).

Direct fuel injection engines definitely spray in liquid. Obviously it doesn't stay a liquid but I would say what it runs on is based on whatever gets fed into the piston, or any part that is directly a part of the engine.

It isn't shocking though as you can run a gas engine on propane. I wouldn't do it with a modern one that has tight tolerances, but for most engine formats until its been optimized to the edge of breaking you can use propane.

Yep, and did you know that temperature is absorbed before combustion? That is because it requires energy to break the bonds in the air fuel mixture. That absorbs heat, after the bonds are broken they re-form, and release the heat and ionized gas via IR radiation we associate with combustion. When fuel is liquid, the hydrogen bonds are too hard to break, but when fuel vaporizes the bonds become easier to break.

Now do diesel

It's the same, except ignition happens via compression and fuel injection alone. Diesel engines use much higher fuel pressure to improve atomization.

I had no idea. What a great explanation,thanks.

man puts primitive carburetor on lawn mower

science!

It's called a lean-burning engine. They tend to burn out. Hole through the pistons, if I remember correctly.

When the engine fails to ignite the AF charge it stays in the combustion chamber, and then the engine injects more fuel, fuel the computer thought was burned. Now you have double the fuel charge, the computer thinks there's no detonation and so bumps up ignition timing, your double charge with advanced ignition timing goes kablammo.

yeeeeeeeeeeeeeeah my motorcycle is a bit of a slow rev engine, if you try and repeatedly rev it it goes nowhere and ignites fuel in the exhaust.

need a power commander, you can get some nice flames going out the back if you do it right...

Pretty sure vapor is exactly the form in which gasoline makes it in to the cylinders, fuel injected or not.

[–] • 0 pt

Someone said it gets hot enough that it vaporizes in there. Especially when there's compression and heat is generated.

[–] [deleted] • 1 pt

You guys need to look up Smokey Yunicks hot vapor engine from the early 80’s

[–] • 1 pt

That's why they got rid of carburetors and went to fuel injection. Several people had converted their 4 door huge 1970 beast mobiles into vapor and getting close to 200 miles per gallon. They couldn't have that now could they. so they lie about injectors being more efficient while in reality they force the liquid to be used and can't be converted to vapors. A 1982 4 door VW diesel was getting like 50+ mpg. A 1982 Honda CRV H model was also over 50 mpg. Now people seem proud their Prius gets 40+?? Also why they buy up or kill people doing water powered engines, that would destroy all their oil business and end the monopoly.

pls stop

Plenty of info out there. You're just lazy. The last water powered car in the news was invented by a couple of Japanese guys. They couldn't find any investors. I doubt the government would let them do it anyway. An engineer for GMC invented one back in the 80's but they wouldn't make it. They made just one for him to drive but they took it back after he died.

as are you 11:30 says it's bullshit

There's a dude running carbon nanotubes in fuel and using light instead of a spark plug to ignite the mixture (single cylinder test engine not real application) . stratified injection is pretty cool stuff but you have to play around with geometries and stuff (pointing a GDI injector straight at the spark plug or the CCIV precombustion chamber) Hydrocarbons become an issue with emissions regulations though and typically are addressed with more expensive catalytic converters (VW TFSI I think is the modern example but it only runs stratified in certain conditions)

I knew this would work because I am always running on fumes. I know when my gas gauge gets to E there is 1/8th of an inch the dial will still go past that when I can make it to a gas station.... sometimes even when it gets to that point I am amazed I still can putter up to the pump... I've only actually had to walk and get gas one time years ago. My 1994 Ford Taurus station wagon has 45k miles on it and is beautiful to me. White with green plush interior, and updated sound system. Air conditioning works great. The ladies love it. I've driven it across country and she has never failed me.

I'd like Project Farm a lot more if the deaf fucker didn't insist on shouting all the time

what's wrong with him? it's just tiring to watch

[–] • 1 pt

He's gone deaf from running small engines indoors.

[–] • 1 pt

Most channels are, way too much talking and not enough editing things down. One reason I linked to the part where he actually runs it.

yep, I haven't watch the first 60 seconds of any youtube video for 10 years, it's just waffle

It's curious how good Americans are at creating content though, we kinda suck in the UK
