Abstract: An efficient, portable, easy to operate tool employing a linear motor is disclosed that is powered by the gases produced from the internal combustion of a fuel and air mixture. A supply of liquified gas stored under pressure in a cylinder provides the source of power. The linear motor is slidably mounted within a cylinder to move reciprocally downwardly and upwardly through a driving and return stroke. A combustion chamber is formed at the upper end of the cylinder. A spark plug powered by a piezo-electric firing device is located within the combustion chamber. The combustion chamber features a turbulence generator, such as a fan, driven by an electric motor which is continuously in operation when the tool is in use. A main valve mechanism actuated by a set of lifting rods that are moved upwardly and downwardly when the tool is moved towards and away from the workpiece, is used to control the opening and closing of the combustion chamber and to control the flow of fresh air through the combustion chamber.

Abstract: There is disclosed a device for atomizing and dispersing fuel in a fuel/air mixture of the propeller type for an internal combustion engine. The housing of the device comprises two concentric barrels, each having a symmetrical bearing support. The barrels are press fit together to assure bearing alignment for the propeller. A downstream screen protects the engine from debris and further atomizes the fuel without substantially restricting fuel/air flow.

Abstract: A fuel atomizer for use in an internal combustion engine is mounted on a bracket and suspended within the air intake passageway of an engine, between the carburetor and the intake manifold, to facilitate the thorough mixing of fuel and air before combustion. When air moves through the passageway, it causes the atomizer to spin, which breaks up fuel droplets and promotes efficient combustion. The atomizer has a cylindrical cage with blades disposed about and parallel to its axis of rotation and with two circular end pieces which abut the blades to form the ends of the cage. The cage is horizontally mounted on an axis of rotation by the bracket which suspends the atomizer in the air passageway.

Abstract: A variation of fuel vaporizer for internal combustion engine is provided that includes an inlet guide vane assembly, and a turbine assembly, the turbine assembly being mounted between the carburetor and intake manifold of the internal combustion engine.

Abstract: A mixture control device for automatically controlling the air to fuel mixture of a conventional carburetor involving a plurality of sloped radial vanes circumferentially located within the annulus formed by the booster venturi and the venturi tube. By inducing significant centrifugal motion in the air passing outside the booster venturi the problems associated with fuel to air mixture changes associated with changes in elevation and changes in seasonal temperatures are alleviated.

Abstract: A device which is located between a carburetor and an engine intake manifold of an internal combustion engine includes oppositely rotating impellers mounted on air bearings. The air-fuel mixture exiting the carburetor impinges on the impellers and drives those impellers. Fuel droplets in the mixture are broken up to form a mixture capable of almost total burnout.

Abstract: A six cycle combustion engine is disclosed which utilizes the 5th and 6th cycle for drawing in and expelling preheated air to further warm the combustion chamber. The flow of the coolant water has been reversed so that heat absorbed in the engine head will flow to the cylinder walls and give a warming trend thereto. In addition, a fuel system is disclosed which insures the complete mixing of air and fuel vapor molecules prior to their deliverance to the intake of the engine.

Abstract: There is disclosed an insert for insertion between the carburetor and the firing chamber of the cylinders in an internal combustion engine. The insert comprises a cylindrical cup-like configuration having a plurality of rectangular apertures symmetrically positioned about the major sidewall and having a pattern of small apertures located on the bottom surface. First and second circular screen members are positioned within the insert to overlie the bottom surface, while a cylindrical screen member is positioned within the hollow of the insert to surround the major side surfaces containing the rectangular apertures.

Abstract: A device and method for installing a device for improving the fuel/air mixture in internal combustion engines with or without a fuel injection system. An intermediate member operatively dispositioned between the engine intake manifold and the intake port comprises at least two helically twisted blades attached to the inner bore of an intake port opening in the intermediate member; these blades are angled in relation to the fuel/air flow path and twisted so as to impart a swirling to the fuel/air mixture. In fuel injected systems, the swirl is imparted to the air flow just prior to encountering the umbrella mist injected to the intake port by the fuel injector. The swirl mixing of the fuel/air improves engine performance, reduces pollutants, and increases gas mileage. Further, in fuel injection systems, the device reduces or eliminates the common occurrence of a burned intake valve caused by a clogged injector.

Abstract: Means for supplying a fuel/air mixture to an internal combustion engine comprises a housing, means for injecting fuel into the housing, means for transferring sufficient heat to the fuel so that substantially all the fuel is vaporized when it leaves the housing, means for admitting air into the housing to form a mixture with the vaporized fuel, outlet conduit means for conducting the mixture out of the housing for combustion in the engine and, preferably, rotor means positioned in the outlet conduit means for rotation by the gases passing through the outlet conduit means.

Abstract: An impeller is secured to one end of a hollow shaft and is positioned within a chamber to which air is supplied. An output line from the chamber is joined with the intake manifold of an engine. The opposite end of the hollow shaft is immersed in fuel. When a vacuum is drawn by the manifold, air flow through the chamber rotates the impeller while fuel is simultaneously drawn through the shaft and discharged into the chamber. The turbulence and agitation of the impeller atomizes the fuel so that an air/fuel mixture is supplied to the manifold through the output line. Pressurized air is applied to the fuel as it rises in the hollow shaft to provide initial fuel atomization.
