This application claims priority to Provisional Application Ser. No. 60/549,230, filed on Mar. 1, 2004.
This application hereby incorporates by reference the following co-assigned U.S patent application, entitled “Vaporizing Liquid Fuel System”.
1. Field of the Invention
The present disclosure relates generally to reducing fuel consumption in automobiles or other internal combustion engines.
2. Description of the Related Art
Gasoline is a limited resource that is the backbone of global economies. As supplies dwindle, fuel costs will continue to increase. Individual consumers and businesses need ways to reduce fuel consumption. One option is to improve gasoline mileage. Ongoing efforts to improve gasoline mileage include hybrid cars that are more expensive. Many newer cars weigh less and generally achieve better gas mileage. However, consumers and businesses that can only afford older cars have little option but to use what they have. In addition, gasoline mileage of many newer cars can be further improved with the present disclosure.
Introduction of fuel-injection systems with better performance has made carburetor systems obsolete. However, both systems share some of the same limitations. In both systems liquid fuel is either injected (sprayed under relatively high pressure) into the engine's intake air stream, or dispersed by carburetor jets (low pressure) into the air stream. Fuel injectors simply produce smaller fuel droplets. If liquid fuel is not fully vaporized, small droplets are formed. At a molecular scale, these droplets regardless of their size are comprised of very large numbers of fuel molecules. As combustion begins, only the surface layer of the droplet is burned. Combustion products surround the unburned fuel droplet and slow further combustion. As a result fuel is wasted and unburned fuel pollutes the environment and contaminates engine oil.
Many fuel evaporators have been developed over the years. However, none of them has become commercially viable. Many systems include a means to return fuel that does not evaporate to the fuel tank. It appears substantially full vaporization has not been consistently achieved. Lacking effective evaporators has hampered development of fuel systems using evaporators. Fuel injector controls regulate how much fuel is injected and that is all. Proposed evaporator fuel systems are more complex. An evaporated fuel system may provide return of un-vaporized fuel, control of temperature, control of liquid fuel level in a vapor chamber, metering of air into a vapor chamber, and an agitator to enhance vaporization. For these and other technical reasons, fuel vaporization for automotive has not become commercially available.
There is a need for a low cost, effective means to reduce fuel consumption in both new and used gasoline powered cars. In order to improve gasoline mileage for most users, a solution must be affordable, available and adaptable for most new and used cars on the market.
A technical advantage of the present invention is substantially full vaporization of liquid fuel. Still another technical advantage is simplicity of design that makes it easily adaptable to existing systems. Yet another technical advantage is compact size of the evaporated fuel system that fits easily into existing vehicles. Another technical advantage is use of readily available low-cost materials and ease of manufacturing. Another technical advantage is ease of starting in extremely cold weather. Another technical advantage is ease of insulation to provide protection from contact burns. Other technical advantages should be apparent to one of ordinary skill in the art in view of what has been disclosed herein.
The present invention may be susceptible to various modifications and alternative forms. Specific exemplary embodiments thereof are shown by way of example in the drawings and are described herein in detail. It should be understood, however, that the description set forth herein of specific embodiments is not intended to limit the present invention to the particular forms disclosed. Rather, all modifications, alternatives, and equivalents falling within the spirit and scope of the invention as defined by the appended claims are intended to be covered.
For purposes of disclosure a fuel system may include any instrumentality or aggregate of instrumentalities operable to control fuel-flow, to condition fuel, to introduce material into fuel, to dispense fuel into an engine, or to in any way manage fuel. An automobile fuel system may include a fuel tank; one or more pumps; control valves; nozzles; hoses or tubing; fuel conditioners with attending components, materials, and controls; sensors; computer processors; and mechanical or vacuum actuated mechanisms.
Referring now to the drawings, the details of specific exemplary embodiments of the present invention are schematically illustrated. Like elements in the drawings will be represented by the like numbers.
Power for the present invention may be supplied by the electrical system.
