Vacuum driven gas vapor system

I did a test with my truck. A very basic run just to see. Air fuel could have been better under demand. In town was just fine. 113.6 miles with 4.78 gallons, 23.75 mpg, 40% above rated mixed driving. ABA or not considering I've put maybe 10 hours labor into this I'd say it's worth my time to keep playing around.

Vapor does allow leaner combustible mixtures and can extend your fuel economy at low power cruise. However, the hot gas and air mix limits the mass of fuel and air into the engine at full power, so, disabling the vapor stream in some way would be needed.

Sorry, this was sarcasm, which does not translate well in text. The "evidence" was his claims, that we should all take at face value

I would have questioned his methodology, but I can't take a claim of 500% improvement seriously

Air and fuel mixes are relative in that an air filter sets the maximum air into the engine.

Instead of being all air and adding gas for loads, vapor running would be more "all gas" and restricting air for loads. Either way

Except in this case the fuel is introduced from behind the throttle plate, so reducing air is easier then demanding more vapor, just like your air filter, the supply only needs to be enough for high demand, only fuel needed is drawn

There is a serious problem when my lawn mower burns less or about the same amount of fuel while cutting grass as the modified one at no load.

After you discover diesel engines and turbochargers, all this vapor lean burn nonsense will seem kind of silly.

Baaaaaa baaaaaaas go back to sleep to continue your American dream. it's just shocking how close minded and ignorant people areespecially considering they don't have any hands on experience but they seem to know everything

Why don't you answer to his specifics? If you can't answer, simply say , "good question, I will have to find out".

If you are going to be an experimenter/inventor, you must have a thick skin and a level headed disposition with clarity of thought. Otherwise, you will come across as a child in play - which right now, you do.

I have practical experience with both advanced diesels and spark ignited engines and neither are "silly". And both can benefit from lean burn and vapor phase technology.

You tool. There wasn't even a question.

Next.
