Abstract: A method and apparatus for operating an internal combustion engine that substantially improves the fuel efficiency by utilizing heat normally discharged to the ambient to condition and prepare the fuel mixture prior to entry into the combustion chambers. The apparatus comprises a fuel vaporizer, a fuel mixture heater and a mixture homogenizer located in a fuel mixture flow path intermediate the vaporizer and the heater. The fuel vaporizer includes structure defining an inner heat exchange chamber which receives air and entrained fuel discharged by a fuel introducing device such as a carburetor. The fuel mixture is heated and at least partially vaporized by engine waste heat derived from the engine cooling system or alternately the engine exhaust system.
Abstract: The invention relates to a valve for apportioning preheated and non-preheated air to an internal combustion engine. The valve has a pivotally mounted valve flap, which is rigidly joined to a balance flap which is so constructed and arranged in the valve body that the low pressure created by the airflow through the valve body gives rise to oppositely directed torques of substantially the same magnitude about the pivot shaft on the balance flap and the valve flap.
Abstract: A plate having a plurality of apertures through which a fuel-air mixture travels is positioned between a fuel injector, such as a carburetor, and an intake manifold of an internal combustion engine. The apertures taper outwardly toward the intake manifold from a restricted orifice area adjacent the fuel injector. The taper of the apertures allows the fuel-air mixture to expand and provides better atomization of the fuel. The size and shape of the apertures is such as to cause ultrasonic sound and reverberation which is a phenomena that helps break up the droplets of fuel into minute droplets. The preferred embodiment includes a ratio of the restricted aperture area in the plate to the total displacement of the engine from 0.006 to 0.012, with the optimum ratio being approximately 0.007. The inside surface of the tapered apertures includes longitudinal flutes extending from the upper to the lower surface of the plate.
Abstract: A device preheats a fuel mixture in an intake manifold of a combustion engine, the device corresponding a cylindrical body having a side wall and a bottom disposed in the wall of the intake manifold. The body is arranged on an electro- and heat insulating contact bearer and is secured on the intake manifold in an electro- and heat conducting way, the bottom of the body being provided with PTC pills which are connected to a current conductor and are secured on the bottom in an electro- and heat conducting way. The bottom has such a thickness and shape that during preheating the fuel mixture a homogeneous heat conduction is created, the side wall of the body having securing means to secure the preheater, and wherein it has such a thickness that together with the securing means it provides the required heat resistance upon heat transfer from and to the intake manifold.
Abstract: An internal combustion engine in which a stream of air from a duct (46) to a cylinder (2) so as to flow adjacent to the cylinder walls. The duct (46) is arranged to admit the air only while the exhaust valve (42) is open. The air will circulate against the cylinder walls during the exhaust stroke but at least a portion thereof will remain adjacent the cylinder walls during the subsequent compression stroke. The combustible charge is admitted generally centrally of cylinder and remains stratified with respect to the circulating air. The circulating air maintains the combustible mixture relatively concentrated for good ignition, cushions the igniting gases, assists in maintaining the cylinder walls clean and cools the exhaust valve.

Abstract: Apparatus for increasing the life of an internal combustion engine, which includes apparatus for closing air inlets to the associated engine, a chamber having a desiccant disposed therein, and fluid communication apparatus connecting the container to at least the crankcase during at least a part of the engine operating cycle.
Abstract: A water-powered light for decorative or utilitarian purposes has a stator assembly mounted on the forward end of a fixed shaft within the housing. The shaft is cantilever supported at one end of the housing and projects forwardly therefrom. A rotor assembly is journaled on an intermediate portion of the shaft. The rotor assembly is axially separated from, but in close proximity to, the stator assembly on the end of the fixed shaft; and the rotor assembly carries permanent magnet means for cooperation with a coil in the stator assembly. A lamp assembly is mounted on the stator assembly forwardly thereof, and a lens cap is mounted on the housing forwardly of the lamp assembly. Water under pressure enters into the housing and passes through canals in a stationary disc member to impinge on an impeller nested within the disc member, the impeller being part of the rotor assembly.
Abstract: A heated fuel delivery system joint and method is disclosed which is most advantageously employed in connection with a fuel oil delivery system for a diesel engine powered motor vehicle. In such fuel delivery systems, fuel processor devices are often employed to prevent fuel clouding and waxing and ice accumulation from restricting fuel flow to the engine. Even when such fuel processors are used, excessively low temperatures of fuel can cause fuel supply problems in fittings and conduits which connect the fuel tank to the fuel processor. In accordance with this invention, these fittings and conduits are warmed by removing a portion of the heated fuel exiting from the fuel processor and introducing it into a fitting at the fuel tank discharge port. By mixing the warmed fuel with cold fuel withdrawn from the fuel tank, the combined temperature of the fuel is increased, thereby minimizing problems associated with excessively cold fuel.
Abstract: An internal combustion engine having a head with valve assemblies for controlling intake and exhaust gases to and from piston chambers. A head plate is located between the head and a block having cylinders accommodating pistons. The head plate has openings in communication with the cylinders and valve assemblies. Each valve assembly has a continuous ceramic sleeve having an intake port, an exhaust port, and ignition hole. Rotatably disposed within the sleeve is a rotatable valve body having a valving combustion chamber open to a piston chamber. A ceramic segment seal member mounted on the valving body has sealing surfaces engageable with the sleeve. A face seal is located between the head plate and the rotating valve body. The valving body and seal member are rotatably driven to sequentially align the valving combustion chamber with the intake port, ignition hole, and exhaust port during the operation of the engine.

The formation consists of a tread plate in perpendicular affixure to a riser plate while extending an overhang portion that is further formed into an overhang plate disposed parallel to the riser plate. A transverse plate is formed to extend between the overhang plate and riser plate to provide high structural strength while also defining a downwardly oriented channel for retention of an illumination source for directing light downward along the adjacent step riser toward the next lower step tread.
Abstract: A vaporizer unit has an enclosing casing including a plurality of tubes therein, defining a fuel passage therethrough, including the tubes. The tubes have coiled wire screen therein. An auxiliary carburetor is positioned at the inlet end of the fuel passage, and an outlet passage leads to the main carburetor of the automobile. The casing also defines an exhaust passage therethrough, transversely of the fuel passage, providing heat transfer between the exhaust gases and the tubes. The temperature of the resulting vaporized fuel is sensed for varying the flow of the exhaust gases and thereby controlling the temperature of the vaporized fuel, which is maintained at 250.degree. F. to 260.degree. F. An electric crystal is used for breaking down the heavy ends of the fuel. The rate of flow of air to the main carburetor is varied for correspondingly varying the rate of intake of vaporized fuel from the vaporizer unit.
