Abstract: A system for supercharging an internal combustion engine. In the present invention, waste heat from an internal combustion engine heats surrounding coolant water to make steam. Steam then passes through a steam compressor, which feeds a high-velocity stream of steam to the intake manifold of the combustion chamber of the engine. This stream draws air and fuel vapor to it, and the resulting supercharged mixture is injected into the combustion chamber of the engine. The high-pressure super-charged mixture exerts pressure on the piston during the intake stroke, increases the pressure inside the combustion chamber, absorbs more heat during combustion, and gathers the engine's waste heat into a high-energy exhaust stream. As a result, the fuel burns more efficiently, less heat is lost from the combustion chamber, engine knocking decreases, thermal stress is reduced, fewer nitrogen oxide pollutants are produced, and the exhaust stream may be used for by-product power generation.

The steam is used to cause full retard of the vacuum spark advance during acceleration at full load from low speed, and a large amount of steam is injected at this point in the cycle to prevent pre-ignition and detonation.

Abstract: A hot fuel gas generator for an internal combustion engine simultaneously vaporizes gasoline and water in a multi-chambered heated pressure vessel having built in regulators for controlling pressure and volume and delivers the resulting superheated steam and gaseous fuel to the intake manifold of the internal combustion engine downstream from the usual air cleaner. A single device operating at a high temperature, for example 800.degree. F., is used for the simultaneous vaporization of the fuel and water to develop desirable working pressure and volume. The high temperature steam and gaseous fuel positions the fuel molecules at the greatest degree of separation from each other providing the greatest opportunity for contact of the oxygen, the reacting species in the gaseous condition as chemical reactions occur only between particles at the atomic or molecular level and it is necessary for the reacting species to be in actual contact at the time of reaction.

There it is vaporized into steam and then passes either through an inlet port into the base of the engine carburetor or directly into the intake manifold. The steam thus produced expands and mixes with and vaporizes the unvaporized droplets of gasoline in the gasoline vapor, breaking up these droplets into gasoline vapor before they can enter the intake manifold.
