  • Patent number: 4913098
    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.

An air intake structure (30) enables an air stream (32) to flow within the conditioner and through air filter (28) into the intake manifold (60) of the engine. The vaporized fuel and water is carried by and combines with the air stream into such intake manifold. Various heating devices (50, 250) are thermally coupled to the conditioner to heat the fuel and water in such conditioner and assist in further vaporizing such fuel and water.

  • Patent number: 4329945
    Abstract: Control apparatus is described for metering a liquid additive to be vaporized and introduced to the fuel mixture for an internal combustion engine. Improved enhancement of the combustion process is obtained by supplying the additive in accurate and reliable dependence upon the condition of operation of the engine, as represented by the pressure in the intake manifold. Such control is made possible by a pressure responsive valve having a valve member movable with low friction along the length of a narrow valve orifice of uniform width. The resulting flow is then linearly related to the movement of the valve member, and provides sensitive and accurate control even at extremely low flow rates. A complete system for combustion enhancement employing such a valve and associated control features is described. Independently adjustable springs at opposite ends of the valve member provide separate adjustment of the flow for engine operation at high and low power conditions.

  • Patent number: 4281626
    Abstract: A four or two cycle internal combustion engine is provided with a device for introducing evaporable liquid into a cylinder of the engine in a manner such that the evaporable liquid is contacted by the gases being compressed during compression phase, is separated, segregated or concealed during most of the combustion phase, and exposed and contacted by the combusting fuel gases primarily after most of the combustion of the fuel gases has occurred for absorbing some of the heat of combustion in the liquid and vaporizing the liquid. The invention is useful both for construction of new Otto or Diesel cycle internal combustion engines, and modification of existing engines.

  • Patent number: 4197819
    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.

  • Patent number: 4150639
    Abstract: Water from a tank is drawn upward by suction created by the vacuum in the carburetor air cleaner or in the engine intake manifold through a filter containing synthetic sponge material sandwiched between upper and lower layers of glass wool, where it passes through a heat exchanger coil which is heated by being positioned adjacent the exhaust manifold of an internal combustion engine. 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.

  • Patent number: 4142481
    Abstract: This invention relates to a vaporific carburetor for a gasoline engine, consisting of an evaporator tube assembly inclined to the horizon, an auxiliary fuel tank assembly at the upper end of the evaporator tube assembly, a mixer tube assembly at the lower portion of the evaporator tube assembly and an auxiliary water tank connected by a small water pipe to the upper portion of the evaporator tube assembly.The vaporific carburetor differs from the vaporizer carburetor in four different aspects. The first difference is in the cut at the outlet of the high speed tube, and the position of the cut with respect to the venturi. In the vaporizer carburetor the said cut is perpendicular to the wall of the venturi while in the vaporific carburetor the said cut is parallel with the wall of the venturi. The second difference is in the connection of the inlet of the idling speed tube.

  • Patent number: 4122803
    Abstract: An internal combustion engine in which a compact ring type boiler pack is installed around each cylinder under the cylinder head. Water is pumped through each boiler at a rate proportional to the cylinder temperature, to maintain a proper cooling and steam injection balance, the generated steam being injected peripherally into the cylinder in pulses, timed by a valve which is controlled by movement of the inlet valve actuating mechanism of the particular cylinder. The boiler has multiple stages to ensure complete conversion of the water to steam, the peripheral steam injection providing internal cooling of the cylinder walls without interfering with normal combustion. The steam system is adaptable to existing internal combustion engines and results in reduced fuel consumption, very low pollutant emissions in the exhaust and a very efficient thermal cycle.
