2. Descriptions of the Related Art
Under the trend towards energy saving and environmental protection, typically a fuel saver may be mounted where the fuel has not yet entered the engine of a car so as to increase the horsepower and reduce the carbon deposit and save the fuel as well.
The conventional fuel saver has a structure that can release far-infrared ray or magnetic energy, thereby finely activating the fuel molecules transported in the fuel pipes to increase the combustion efficiency and fulfill the purpose for fuel saving.

Please also refer to FIG. 2, which shows a cross sectional view of the fuel economizer according to a first embodiment of the present invention. The fuel economizer 2 is used for transporting the fuel supplied from the fuel supply source 1 to the engine 3 for combustion. A pipeline 4 has fins 41 thereof for preheating the fuel flowing through a chamber 5 thereof so that the temperature of the fuel can be increased beforehand and the fuel having been in the engine 3 can reach easy ignition and complete combustion, and thus reducing waste gas produced. Moreover, a plurality of magnetic elements 6 disposed within the chamber 5 of the pipeline 4 can release magnetic energy to finely activate the fuel molecules and then to increase the combustion efficiency of the fuel so as to fulfill the purposes for fuel saving and horsepower increase. The magnetic elements 6 also can absorb the impurities carried in the fuel so as to lengthen the lifetime of the engine 3.

The fuel economizer 2 of the present invention comprises a pipeline 4 with thermal conducting elements and having a chamber 5 for the fuel to flow through (as shown by the arrows a in FIG. 2), a plurality of magnetic elements 6 each of which provided with a through hole 61 and wrapped within a metal element 7 that is formed with a plurality of spacings 72 and disposed within the chamber 5 of the pipeline 4, and a plurality of elastic elements 8 disposed within the chamber 5 of the pipeline 4 and located at two opposite sides of the magnetic elements 6, respectively.
In this preferred embodiment, the thermal conducting elements of the pipeline 4 are annular fins 41, wherein the fins 41 have the surface areas thereof used for absorbing a large quantity of heat from the outside of the fuel economizer 2 to preheat the fuel flowing through the pipeline 4. The magnetic elements 6 are magnets, which are arranged in a way such that neighboring magnetic elements 6 have like polarities, and like poles are adjacent each other (as shown by the N-pole and S-pole in FIG. 2). Each of the metal elements 7 has a plurality of protrusions 71 and wraps one of the magnetic elements 6, wherein the protrusions 71 are integrally formed with the metal element 7 and extend outwardly from the metal element 7 so that the plurality of protrusions 71 contacts the inner surface 42 of the pipeline 4 and thus a plurality of the spacings 72 are formed between the metal element 7 and the inner surface 42 of the pipeline 4 for the fuel to flow through. The metal element 7 also protects the magnetic element 6 from being damaged due to undue external force. The metal element 7 can be made of copper, iron, aluminum, tin, zinc, nickel, gold, silver, lead, palladium or other composite metals. The elastic elements 8 are springs, which are disposed on two opposite sides of the magnetic elements 6, respectively, and used for buffering the repulsion fore produced by the magnetic elements 6 due to being arranged in like polarities from each other. The elastic elements 8 also can absorb over-displacement and over-vibration of the magnetic elements 6 when the fuel flows through the chamber 5 so as to stabilize the magnetic elements 6. Moreover, two engagement parts 9 are disposed at two ends of the pipeline 4. Each of the two engagement parts 9 is formed with inner surface threads 91 and outer surface threads 92. The inner surface threads 91 of the engagement parts 9 are used for engaging with outer surface threads 43 of the pipeline 4. The outer surface threads 92 of the two engagement parts 9 are used for engaging with a fuel supply piping 93 and an engine piping 94, respectively.
When the fuel flows through the chamber 5 of the pipeline 4 in the direction indicated by the arrows a as shown in FIG. 2, the fuel flows smoothly over the through holes 61 of the magnetic elements 6 and the spacings 72 of the metal elements 7, wherein the magnetic elements 6 release magnetic energy to finely activate the fuel molecules to increase the combustion efficiency of the fuel so as to fulfill the purposes for fuel saving and horsepower increase. The magnetic elements 6 also can absorb the impurities carried in the fuel so as to lengthen the lifetime of the engine 3. Moreover, the fins 41 have the surface areas thereof used for absorbing a large quantity of heat from the outside of the fuel economizer 2, and conducting the heat to the inner surface 42 of the pipeline 4 so as to preheat the fuel flowing through the spacings 72. As a result, the temperature of the fuel can be increased beforehand to reach an ignition point for facilitating ignition and complete combustion, and thus reducing waste gas (carbon deposit) produced.
