US 4,208,989 A · Water vapor injection system

Abstract

The present invention relates to a water vapor injection system for introducing artificially high humidity air into the carburetor of an internal combustion engine. Once delivered to the carburetor, the high humidity or moisture-laden air mixes with the air-fuel mixture normally passing from the carburetor into the combustion chambers to increase the combustion efficiency of the internal combustion engine. A forced air system is generated by an air injection pump, and this forced air is heated to alter its vaporization characteristics prior to being circulated through a water filled container. As the heated air is exposed to the water within the container, the air increases in moisture content as the heat associated with the air tends to vaporize water about the interface between respective bubbles and the surrounding water. Because of the continuous force of the pump, the high moisture air realized from passing the air through the water filled container is then forced from the container into the immediate area of the top of the carburetor. There the moisture-laden air generated by the water vapor injection system is mixed with the normally injected air supply and, accordingly, the water content of the final air-fuel mixture is increased which, expressed generally, significantly increases the efficiency of the combustion process within the internal combustion engine.

Dependent claims

A process of generating and injecting water vapor into an air-fuel mixture passing from a carburetor of a combustion engine comprising:

(a) forcing ambient air into and through an air inlet means;
(b) preheating said ambient air to at least 100.degree. C. while the same is being forced through said air inlet means;
(c) directing the forced heated air from said air inlet means directly into a volume of water contained in a water container wherein moisture becomes associated with the air moving through the water as an evenly dispersed foaming action is realized as the forced heated air moves through the volume of water;
(d) continuing to force the cooled moistened air from said water vapor container through an air outlet means;
(e) directing the moistened air in said air outlet means to said engine carburetor and discharging the moistened air directly into the air intake area of said engine carburetor;
and
(f) mixing said moistened air with the air-fuel mixture passing through the engine carburetor prior to the combined mixture reaching the engine intake manifold.

A water vapor injection system for adding moist air to the air-fuel mixture passing through a carburetor into the combustion chamber of an engine, said water vapor system comprising:

a water container means completely independent of the engine and engine cooling system adapted to contain a volume of water therein for moistening air being passed therethrough prior to reaching said engine;
an air inlet means operatively connected to said water container means, and including interior air inlet means extending interiorly of said container means and having air exit opening means disposed at a position below the normal level of the water in said container means;
an air pump means operatively connected to said air inlet means for forcing ambient air therethrough and into said water container means and out said air exit opening means and through said volume of water within said container means, such that an evenly dispersed foaming action is realized as the forced air moves through the water in said water container means and the air becomes moistened air in the process;
means for heating the forced air generated by said pump means to at least 100.degree. C. prior to entering said water container means in order that the heated air passing through the water as air bubbles may act to vaporize water about the interface between the heated air bubbles and the surrounding water;
and an air outlet means operatively connected between said water container means and the carburetor intake area of said engine for receiving the moistened air leaving said water container means and delivering the same to the carburetor of said engine where said moistened air mixes with the air-fuel mixture passing from the carburetor into the combination chambers of said engine.
