Abstract
Abstract For introducing water in vapor form to the intake manifold of a combustion engine use is made of a double walled heat exchanger. Exhaust from the engine is passed through the space between an inner wall and an outer wall and then returned to the exhaust pipe. A chamber within the inner wall provides a reservoir of water and accommodates a float to control the level. For transporting vapors to the intake manifold of a combustion engine, a vacuum line from the intake manifold is in communication with the chamber at a location above the water level and induces air to flow through an air intake to a location adjacent the bottom of the water reservoir, releasing large bubbles of air below a dispersing plate through which a plurality of streams of small bubbles emerge bubbling to the surface, and entrain hot water vapor. The mixture of water vapor is then carried upwardly by the vacuum through a set of fine screens and then through to the engine intake manifold at a location adjacent the fuel air mixture passage at the outflow end of the carburetor.
