Just out of curiosity, has anyone ever tried the gas vapor setup on there scooter. The ideas been around for a while. Was watching project farm on YouTube (excellent videos from this guy if you've never watched) and thought about trying same idea on a stock 50 4t. Obviously don't really need to do it for added fuel mileage on one given 70-80mpg stock, but wondering what the results might be.  youtu.be/IuGWHfWqWtg |

For the 2-3% he saw, I don't think it would be worth the effort for practicality. About 1-3MPG with what a typical stock 139QMB would do. Maybe for an enthusiast just wanting to tinker or for someone into hypermiling that is not concerned with any potential failures?
I know basically nothing about the idea though, so everything I think or say may be totally wrong.
Smokey Yunick messed around with some idea of running on fuel vapors with success and even made much more power, but his system was way complex compared to what most of the fuel vapor info like that vid show. He had a turbo and heat exchanger and all sorts of things going on. They also talked about air/fuel ratios of 20:1 or leaner. Not sure that's gonna work out on an air cooled engine. We generally have to run richer than other engines just to keep from overheating. I also keep seeing vids of cars idling. Cool, but send them to the races if you want something more comparable to what our scooters go through. The mowers seemed to handle the load of mowing short grass. Can't say that's enough to make me wanna go for a test run of a vapor system though, since they are generally really low compression oversized engines that are designed to run in crappy conditions. Example, one of my riding mowers is something like 800cc to make 25HP. Generators are kind of in the same boat AFAIK.
Again, just random thoughts from an uneducated opinion on the subject.

A friend of mine use to run his unimog truck on propane use to keep 2 large bottles in the load bed before he moved back to the States and another friend run on propane bottles in his VW Transporter. I had all the gubbin's to do a car but went a different route and used old veg oil for a few years till evryone caught onto the idea and chip shops and resturants started charging you for it instead of being free.

propane has been used for years, especially to power diesel engines, forklifts etc, but we are talking two different things here that are nothing alike.

Ah I not heard of vapour before, I thought it might be an Americanism for gas, ie propane or butane. Now I am causing confusing as you call petrol gas. Best I get myself a American dictionary 😊 By the way sorry to hear about your friend. |

Petrol fumes good sir. Gassing gasoline instead of liquid state

Petrol fumes good sir. Gassing gasoline instead of liquid state if you are going to go to that trouble, get a propane converter for the carb, they probably even have an off the shelf kit, as they use propane to power small engines for things like floor buffers. |

I know this subject had been discussed briefly a year or so ago, but i'm still considering an hho powered scoot. Before i get the usual responses or questions - no, i'm not doing it for the fuel savings, i know scoots are petrol sippers. No, i'm not doing it to be greener to the planet even though i know emissions from fossil fuels aren't a good thing. Yes, i do know the concerns about stainless erosion in an electrolosis bath, i would plan to use a more easily available mild steel piece and replace it 5 times more often just to avoid creating and disposing of hexavalent chromium. "Why change something that already works just fine the way it is?" Why not try to innovate, think way outside the box, do what few would even consider possible, experiment and try new things - even if you find you couldn't get it to work, and to enjoy tinkering just because? I know many of my ideas are long shots (ask 190mech, we've discussed thousands of things outside the box), but a few of them might work. If they do, its something special that very few can replicate on their own. Or some kind of tech the big corp/govt dont want us having lol sorry, had to make a conspiracy pun there... Why? Just so i could say i have a scoot that runs on water... Why not? |

Our scoots already run on fuel vapor. The carb atomizes the gas and the compression vaporizes it. By the time the mixture goes boom it is a vapor mix.
Hydrogen fuel is really only efficient if it is made from geothermal energy like in Iceland or from renewable sources like wind. It is just a way of storing energy for later use.
Gasoline is just a type of energy storage medium also. Energy made from whale dung and star dust and cooked underground, then extracted and refined.
