Vapor carburator
Years ago Popular Science magazine had ads in the back by a company called H A industries.
They carried how to manuals to all kinds of energy saving devices and a couple were two vapor carburators. One used the vehicles hot water to preheat the gas. The other used hot exhaust. A manual fuel injector was to be used until the vehicle reached normal running temperature.
I had one built but the v8 Chevy truck took a **** before I could try it out.
They were intended for carburated vehicles.
It was claimed that any vehicle could double fuel mileage with them.
Has anyone else here heard of them or are otherwise familiar with them?
I am thinking on trying it out on my 1989 Ford Festiva.
