  • Patent number: 3942499
    Abstract: The system and apparatus herein incorporate means for effectively and significantly reducing the liquid components of the fuel mixture passing through a cylinder located between the carburetor and the intake manifold of an internal combustion engine. The invention includes a stationary circular array of radially arrayed overlapping slanted spaced baffles or blades located in the fuel stream. Formed or otherwise mounted on the lower or trailing edge of each blade is a radially extending flange or scoop which catches and projects liquid components from the fuel stream through a corresponding aperture in said cylinder and into a collection chamber surrounding said cylinder. The collection chamber contains a reticular, webbed, or porous material for retention and drainage of the excess liquid components. Additional means are provided to restore a desired quantity of liquid fuel to the fuel stream when the engine requires temporary surge or demand power.

  • Patent number: 3942500
    Abstract: The system and apparatus herein incorporate means for effectively removing significant quantities of liquid components from the fuel mixture while the latter passes from the carburetor to the intake manifold of an internal combustion engine, and for recovering said liquid components and recycling them through the fuel supply system in order to effect appreciable savings in fuel consumption during operation of the engine. The invention includes means for centrifuging liquid components from the fuel stream into an adjacent collection chamber whence said liquids move continuously into a drain tank which maintains a closed system with the collection chamber. The capture of liquids in the collection chamber may be improved by incorporating a reticular packing therein. Additional means are provided to restore a desired quantity of liquid fuel to the fuel stream when the engine requires temporary surge or demand power.

  • Patent number: 3937197
    Abstract: A water-cooled combustion engine has a pump-operated cooling water circuit passing through the cooler when the engine is hot. The cooler is rendered inoperative by a thermostat-controlled by-pass line when the engine is cold. The heating means for the intake system for the engine has a cooling water chamber whose supply line is fed with heated cooling water. The circuit of the heating means is arranged parallel with the cooling circuit through the by-pass line. This heating means is automatically switched off without additional aids as the engine temperature rises, when the by-pass line is shut off by the thermostat valve.
