Abstract

A fuel dispersion device has been provided in the form of a vacuum pump in which fuel is injected as macroscopic fuel droplets in metered quantities into a vacuum chamber in the pump where it is converted to a converted fuel in the form of a mixture of a smaller percentage of gaseous fuel and a larger percentage of microscopic liquid fuel droplets. This converted fuel is moved from the inlet to an outlet port by sweeping vanes. A combination of vacuum, expanding absorbed gases, mechanical energy and thermal energy is used to create gaseous fuel and microscopic liquid fuel droplets from macroscopic liquid fuel droplets. An air intake passageway is provided at one end of the mixing chamber at substantially right angles to the outlet from the vacuum chamber. An air-fuel discharge passageway is provided on the opposite side of the intake passageway for supplying the mixture of air and converted fuel to the engine for combustion. The mixing chamber is larger in area than the intake passageway so that the air slows down as it passes through the mixing chamber to allow for thorough mixing with the converted fuel. In addition, a diverter is provided in the center of the mixing chamber to further create turbulent flow of the air to assure thorough mixing. The mixing of relatively warm air with the microscopic droplets causes further evaporation and droplet size reduction. The entire system is operated by an electronic fuel management control module.
