Catalytic Carburetors
A catalytic carburetor mixes fuel vapor with water and air in the presence of heated catalysts such as nickel or platinum. This is generally reported as a 1940's-era product that would allow kerosene to power a gasoline engine (requiring lighter hydrocarbons). However reports are inconsistent; commonly they are included in descriptions of (e.g.) "200 MPG carburetors" intended for gasoline use. There seems to be some confusion with some older types of fuel vapor carburetors (see vaporizors below). There is also very rarely any useful reference to real-world devices. Poorly referenced material on the topic should be viewed with suspicion.
