  • Patent number: 4306519
    Abstract: A vaporizer cooperating with a recirculating water system humidifies air before it enters the carburetor of an automobile engine. The vaporizer is generally a hollow tube which includes an evaporating pad that distributes liquid such as water. As air moves through the vaporizer, vapor moves into the air stream. Excess liquid is collected at the bottom of a larger portion of the vaporizer, whose air outlet is elevated from that bottom to prevent liquid phase water from leaving the vaporizer. The recirculating system drains collected excess water.

  • Patent number: 4290392
    Abstract: A fuel system for and a method of operating an internal combustion engine wherein an aqueous solution of hydrogen peroxide is injected into the combustion chamber after a conventional fuel and combustion gas mix (i.e. gasoline-air) has been ignited. The hydrogen peroxide and water charge supplies additional oxygen to insure complete combustion of the hydrocarbon fuel and simultaneously the high energy content present in the hydrogen peroxide serves to boost the power output of the engine. Furthermore, the water in the hydrogen peroxide charge produces a washing effect on the engine combustion chamber which enables combustion to proceed at a lowered temperature which results in lowered NO.sub.x content of the exhaust gas. The more complete fuel combustion brought about by this system also eliminates the need for catalytic converters.

  • Patent number: 4286550
    Abstract: A fuel additive injection device for injecting an additive into an automotive engine to slow down the burning rate of gasoline while the engine is under heavy load, thereby reducing knocking or pre-ignition while increasing engine output power and increasing fuel mileage. A vacuum chamber having a diaphragm therein is connected to the intake manifold of the engine so that the diaphragm moves back and forth as the pressure in the intake manifold changes. A connecting rod is coupled to the side of the diaphragm opposite to the interior of the chamber. A needle valve connected to the diaphragm through a control rod and a connecting rod and positioned through a valve seat in a flow control passage regulates the flow of additive into the intake manifold of the engine, preferably through the throat of the carburetor. When the pressure in the chamber increases corresponding to a heavy engine load, the needle valve opens increasing the flow of additive to the engine which in turn reduces the burning rate.

  • Patent number: 4182278
    Abstract: A unique process is disclosed for modifying an automobile engine to improve fuel economy and reduce harmful exhaust emissions by introducing water and an oxidizing agent, such as hydrogen peroxide, when the engine is under load. The carburetor of a standard engine is adjusted to provide a very lean air-fuel mixture and to increase the air-fuel ratio substantially (e.g., 10 to 20 percent). The amount of hydrogen peroxide injected into the engine depends on the rate of fuel flow and may be regulated by the throttle valve or intake manifold pressure. Means are provided for maintaining a supply of hydrogen peroxide including a high pressure mixing tank containing water and hydrogen peroxide and a pair of removable oxygen tanks for a continuous supply of oxygen to the tank.

  • Patent number: 4108113
    Abstract: It is common practice to discharge waste vapors from certain chemical processes into the atmosphere. Many of these vapors, usually referred to as "vent gases", contain compounds which are considered to be pollutants in the atmosphere. In this invention the vent gases are oxidized in the combustion chamber of a Diesel engine before release to the atmosphere. The oxidation step reduces the concentration of noxious compounds in the vapor to a level acceptable for atmospheric discharge.

    Abstract: An internal combustion engine carburetor is provided with means for introducing two separate types of liquid into the engine, one of the liquids being gasoline and the other a non-gasoline liquid, such as methyl alcohol, tertiary butyl alcohol, or other alcohols. The carburetor maintains the two liquids separate prior to their introduction into the Venturi to avoid problems normally incurred in blending other liquids with gasoline in liquid form and is constructed to prevent introduction of the non-gasoline liquid during normal idling and starting conditions and to introduce it in metered quantities during normal operation. To ensure vaporization of the two liquids in the primary Venturi, hot air at a temperature at least as high as the end point of the gasoline is introduced directly into the primary Venturi.
