  • Patent number: 5779993
    Abstract: An improved catalyst assembly for vapor/liquid contact towers. Catalyst media used to promote chemical reactions is secured substantially in the liquid phase of the tower, such as in the lower portion thereof for improving mass transfer efficiency. Unlike previous process tower assemblies, wherein distillation in conjunction with chemical reaction occurs in the vapor phase or in a mixed phase, the present invention substantially confines the reaction step to the liquid phase. In this manner, the reaction is less obstructive to vapor flow within the tower, promoting better mixing and diffusion of the feed components.

  • Patent number: 4933116
    Abstract: A device for preventing damage to the carburetor power valve during engine backfire conditions. The device, which comprises an internal one-way valve and is threaded at one end, is used to replace a throttle body mounting screw on the bottom of the carburetor. Used in conjunction with the device is a means to block the original vacuum port to the power valve and redirect the vacuum through the device.

  • Patent number: 4441477
    Abstract: A fuel economizer system for use with an internal combustion engine comprises an evaporation chamber into which gasoline is sprinkled, and in which evaporated gasoline is mixed with air; a two-way safety valve arrangement permitting the mixture to be drawn from the chamber to the intake manifold of the engine but preventing backfires from reaching the chamber; and a return fuel line for recycling the sprinkled gasoline by returning it from the chamber to the fuel tank. A portion of the return line in contact with the exhaust pipe picks up exhaust heat to energize the recycled fuel.

  • Patent number: 4399079
    Abstract: A novel method and improved apparatus are disclosed for generating fuel vapor from a volatile normally liquid fuel, safely handling and controlling the fuel vapor, and utilizing the same in the operation of an internal combustion engine. Preferably, the fuel vapor is generated by introducing the liquid fuel under pressure into the lower portion of a vessel via an elongated tubular member having a plurality of spaced openings. The pressurized liquid fuel flows from the openings under vigorous conditions of agitation and fuel vapor is evolved from the liquid surface without forming finely subdivided liquid droplets in the vapor phase. Air is mixed with fuel vapor in the upper portion of the vessel in an amount sufficient to lower the dew point, but insufficient to produce an explosive mixture. The mixture is withdrawn from the vessel and, after adding sufficient air to produce an explosive mixture and for efficient combustion, is passed to the intake manifold.

  • Patent number: 4336783
    Abstract: A fuel vaporizer carburetor provides a continuous mixture of vaporized fuel and combustion air for operation of an internal combustion engine to meet the requirements of a wide range of engine operating conditions. Fuel vapor and combustion air undergo turbulent intermixing in an elongated mixing chamber. The mixing chamber is enclosed by a tubular wick of fiber mesh material which is saturated with fuel vapors and fuel condensate. The fuel vapors are generated by heating fuel in a float bowl which underlies the wick. Combustion air is admitted through a plurality of angularly spaced openings and is conducted through the porous flow passage provided by the tubular wick prior to entry into the mixing chamber. This arrangement produces a cyclonic, whirling movement which promotes intermixing of the combustion air and fuel vapors. Turbulence is induced at an intermediate point in the mixing chamber by a tapered sidewall housing section.

  • Patent number: 4283355
    Abstract: A carburetor for connection to an internal combustion engine having a housing provided with a mixing passage for the flow of air to the engine; a throttle at the downstream end of the passage; a fuel spray bar extending transversely across the passage upstream of the throttle having transversely oppositely disposed fuel orifices facing the walls of the passage; a pair of venturi plates mounted for pivotal movement about individual axes upstream of the bar and spaced oppositely and transversely from the bar, the plates having distal ends and pivoting between closed, convergent positions in which the distal ends are adjacent to the bar and open positions in which the plates diverge from the bar, thereby defining an adjustable throat; a source of fuel; a conduit interconnecting the orifices and the source; a plunger-actuated valve in the conduit for controlling the flow of fuel from the source; a rotationally mounted cam adjacent to the valve having a cam surface in controlling relation with the valve; and a lin

  • Patent number: 4153651
    Abstract: This invention is concerned with carburetion of gasoline for the purpose of reducing the consumption of gasoline and preventing pollution. The procedure for carrying out this function is by evaporation and osmosis. In the lower chamber of the carburetor where the liquid gasoline is located are immersed a plurality of special tubes. The tubes have in their lower portion on the inside surface an absorbant material, and wicks extending therefrom. In the upper portion of the tubes where the wicks are located, there are a plurality of lateral openings. The gasoline is located in a lower chamber where the tubes are immersed. The upper portion of the tubes are not immersed in the gasoline. When the motor is turned on, the intake valve opens and air is drawn through the air filter in the carburetor and down into the tubes. The air contacts the wicks in the tubes, vapor is formed, and passes through the openings thereof into a chamber which has a protective material located therein.

  • Patent number: 3969445
    Abstract: A carburetor has a choke device formed of two planar quadrangular choke flaps situated side-by-side in a cross-sectionally quadrangular flow passage of an engine intake manifold. The pivotal supports for the choke flaps are held in recesses of the manifold wall and define a pivotal axis that lies in an edge zone of the choke flaps that is immediately adjacent the manifold wall. The choke flaps further have cooperating edge zones that together define the cross section of the flow passage as a function of pressure conditions in the intake manifold. In the fully open position, the choke flaps are in a face-to-face engagement with opposite wall portions of the intake manifold.
