Eddy flow generator to increase horsepower of an internal combustion engine

[0002] 1. Field of the Invention

[0003] The present invention relates to an eddy flow generator, and more particularly to a horsepower booster for an internal combustion engine by changing an air flow pattern into the combustion chamber so as to increase a mixture between air and fuel.

[0004] 2. Description of Related Art

[0005] Superchargers, turbos, air blowers and many other designs are used for internal combustion engines to boost horsepower output of a variety of engines. However, all these auxiliary horsepower boosting designs are either too far away from the combustion chamber or too complex and expensive to mount on the engines. If the auxiliary horsepower booster is mounted too far away from the combustion chamber, the strength of air flow into the combustion chamber is decreased so that only minor change in the horsepower output can be observed.

[0006] To overcome the shortcomings, the present invention tends to provide an improved eddy flow generator to mitigate the aforementioned problems.

[0007] The primary objective of the present invention is to provide an improved eddy flow generator which is close to the combustion chamber and inexpensive such that the effectiveness of increasing horsepower output can be easily observed.

[0008] Another objective of the present invention is to provide an improved eddy flow generator having a stop integrally formed with the eddy flow generator to correspond to a fuel injector so that before entering the combustion chamber, the fuel is atomized to completely mix with incoming air.

[0009] Other objects, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

[0010] FIG. 1 is a cross sectional view of an internal combustion engine mounted with the eddy flow generator of the present invention;

[0011] FIG. 2 is a perspective view of the eddy flow generator of the present invention; and

[0012] FIG. 3 is a schematic view showing that when the air is sucked into the combustion chamber, due to the spirally formed blades of the eddy flow generator, a full mixture of air and fuel is accomplished.

[0013] With reference to FIGS. 1 and 2, the eddy flow generator in accordance with the present invention includes a sheet of material formed as an elongated base (11) positioned at a joint of an intake manifold (30) and a fuel injector (22) of an internal combustion engine (20).

[0014] The eddy flow generator of the present invention further has multiple passages (12) defined through the base (11) to correspond to and communicate with air paths (31) of the intake manifold (30), a stop (14) formed on a top portion of the base (11) and holes (15) defined around each of the passages (12). Each passage (12) has multiple spirally formed blades (13) respectively orientated into or away from the internal combustion engine (20). That is, the orientation of the blades (13) is either consistent to the direction of the air flow in the engine or opposite to the air flow direction in the engine (20). In the preferred embodiment shown in the accompanied drawings, the orientation of the blades (13) is consistent to the air flow direction.

[0015] With reference to FIG. 3, after the eddy flow generator of the present invention is mounted at the joint of the fuel injector (22) and the intake manifold (30) to function as a bushing, the stop (14) is in front of the fuel injector (22) so that whenever there is an injection of fuel into the combustion chamber (21) from the fuel injector (22), the fuel is stopped by the stop (14) and thus atomized. At the time when the fuel is atomized, the vacuum suction force in the combustion chamber (21) attracts air outside the engine (20) to flow into the combustion chamber (21) via the intake manifold (30). Thus when the incoming air in the intake manifold (30) passes through the passages (12), the atomized fuel is mixed with the incoming air. Furthermore, due to the spirally formed blades (13) in each of the passages (12), the air flow pattern in the combustion chamber (21) is changed accordingly. The spiral path of the air and fuel increases the full and optimum mixture between the air and the fuel such that the engine horsepower generated from the explosion of the air-fuel mixture is increased.

[0016] In summary, the eddy flow generator of the present invention has the following advantages:

[0017] {circle around (1)} simple in structure

[0018] {circle around (2)} easy to mount on the engine

[0019] {circle around (3)} does not draw any power from the engine

[0020] {circle around (4)} constant, yet steady horsepower output

[0021] {circle around (5)} increase in engine efficiency, and

[0022] {circle around (6)} reduction of air pollution due to complete mixture between air and fuel

[0023] It is to be understood, however, that even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
