Description

Internal combustion engine gasket

The present invention relates to a gasket, and more particularly to a gasket installed at the fuel inlet of an internal combustion engine.

At present, in the current power plant design of a car, the mixing ratio of fuel and air injected into the combustion chamber of the engine is fixed due to the limitation of the existing structure. However, the mixing ratio of fuel to air cannot be optimized. In the mixed state, the fuel after the mixed air can not fully burn in the engine combustion chamber to exert its proper horsepower, and also the fuel can not be completely burned, resulting in fuel consumption and incomplete combustion of fuel components, which are discharged with the exhaust manifold. And seriously affect the air quality.

Therefore, in order to fully mix the air and fuel, and then enter the combustion chamber of the engine to completely burn, in order to improve the engine horsepower, the improvement scheme known today is to install an air vortex device at the inlet of the intake manifold, such as Attached to Annex 1, Announcement No. 2717 768, "Improved Device for Air Vortex Device", which uses the blades on the air vortex device to guide the air entering the intake manifold to generate a rotating vortex, thereby utilizing The air flow rate is increased, so that the fuel at the fuel inlet of the injection engine is mixed with the air, and then enters the combustion chamber of the engine to ignite and burn, thereby generating power to drive the vehicle to move.

Only the design of the air vortex device installed in the intake manifold can increase the air flow rate into the combustion chamber of the engine. However, the air vortex device is installed at the air inlet of the intake manifold through the engine combustion chamber. The air that generates vacuum into the intake manifold is distributed to the combustion chambers of the engine through the branches of the manifold. Due to the flow of the airflow branching and the long distance of the air inlet to the combustion chamber of the engine, the air flow of the original lifting flow rate is increased. It can be weakened again, so that the air vortex device can not fully exert its function to achieve the intended purpose.

The present invention is intended to solve the problem that air and fuel cannot be sufficiently mixed in an internal combustion engine.

In order to solve the above problems, the present invention provides an internal combustion engine gasket disposed at a fuel inlet of an internal combustion engine. The internal combustion engine gasket is provided with a plurality of oil inlet holes corresponding to the fuel inlet of the internal combustion engine, and between the oil inlet holes A rib, the rib extending away from the spacer to form a blade, the edge of the blade having a plurality of convex portions.

The invention has the beneficial effects that the ribs between the oil inlet holes extend the blades to generate eddy currents of the incoming air and fuel, thereby improving the overall combustion efficiency; and the convex ends are extended by the blade edge to provide different eddy current effects. And using the block corresponding to the fuel injection port of the internal combustion engine to atomize the fuel and improve the combustion efficiency.

In order to further understand the technology, method and effect of the present invention in order to achieve the intended purpose, reference should be made to the detailed description and drawings of the present invention. The drawings and the annexed drawings are intended to be illustrative and not to limit the invention.

1 is a perspective view of a gasket of an internal combustion engine of the present invention. Referring to Figure 1, the present invention An internal combustion engine gasket 1 is provided. Fig. 2 is a view showing a state of use of the internal combustion engine gasket 1 of the present invention. As shown in Fig. 2, the internal combustion engine gasket 1 provided by the present invention is applied to the fuel inlet of an internal combustion engine 9 to increase the combustion efficiency of the fuel. The structure is explained first, and then its setting position and effect are described.

As shown in FIG. 1, the internal combustion engine gasket 1 is provided with a plurality of oil inlet holes 10, and a plurality of oil inlet holes 10 form a rib 11 which faces away from the internal combustion engine gasket (ie, both sides of the internal combustion engine gasket). Extending to form a blade 12. The vanes 12 may extend outwardly of the internal combustion engine 9 and may also extend inwardly. The blade 12 has a bending angle of 30 to 50 degrees, and the blade 12 has a surface area of 16 mm ² to 55 mm ² . The bending angle and the surface area are selected according to the specifications of the internal combustion engine 1 .

The blade 12 extends from the end edge of the rib 11 with a plurality of convex portions 121. As shown in FIG. 3 to FIG. 7, the convex portion 121 can have various presentation forms, and three or four ribs 11 can be formed together between the plurality of oil inlet holes 10. . A stop portion 13 is formed at the junction of the periphery of the oil inlet 10 and the periphery of the rib 11. The internal combustion engine gasket 1 is also provided with a plurality of screw perforations 20.

As shown in FIG. 2, the internal combustion engine gasket 1 is disposed in an internal combustion engine 9. The internal combustion engine 9 includes an intake pipe 91 and a body 92. The body 92 has a chamber 921 as a power supply combustion chamber, and the body 92 has at least one connection. The fuel inlet 922 of the chamber 921 communicates with the inlet 921 through the fuel inlet 922.

The internal combustion engine gasket 1 is fixed to the fuel inlet 922 of the internal combustion engine 9 through a screw perforation 20 by means of a fixing member (not shown), that is, between the intake pipe 91 and the body 92. A portion of the plurality of oil inlets 10 corresponds to a fuel inlet 922. Further, the stopper portion 13 corresponds to the fuel nozzle 93 of the internal combustion engine, and the gasoline discharged from the fuel nozzle 93 strikes the stopper portion 13 so that the fuel becomes a small molecule, is in an atomized state, and passes through the oil inlet hole 10 into the chamber of the internal combustion engine. When the fuel and air pass through the oil inlet hole 10, it increases its eddy current due to the blade 12, and further, the fuel passes through the convex portion 121 to make the eddy current larger. Eddy currents allow the fuel to be thoroughly mixed with air to increase overall combustion efficiency.

3 to 6 are schematic views showing a second embodiment to a sixth embodiment of the internal combustion engine gasket 1 of the present invention. As shown in FIG. 1, the plurality of convex portions 121 may be in a zigzag shape. As shown in Figure 3, The edge of the convex portion 121 has a rounded curve. As shown in FIG. 4, the convex portion 121 has a zigzag shape, and the sizes of the two convex portions 121 are different, so that the convex portions 121 are sequentially arranged in accordance with the size. As shown in Fig. 5, the blade 12 extends three convex portions 121, the convex portion 121 has a zigzag shape, and the convex portion 121 is shorter. As shown in FIG. 6, the blade 12 extends four convex portions 121. In the foregoing FIGS. 3 to 6, the four oil inlet holes 10 collectively correspond to one fuel inlet, and four oil inlet holes 10 form four ribs. Further provided by the above-described blades 12, convex portions 121 and ribs 11 of different forms, different eddy current effects are provided. The number of ribs 11 and the shape of the convex portion 121 can be arranged in accordance with the eddy current requirement.

The process of entering the internal combustion engine 1 will be described below. From the above, it can be seen that the fuel impinges on the block 13 and is in an atomized state. The atomized state fuel passes through the oil inlet port 10, and due to the arrangement of the blades 12, the fuel changes the flow field pattern along the blade 12, and provides an angle of attack by the angle of the blade 12, so that the blade 12 is in contact with the fuel. The viscous force changes to create a turbulence. Then, the fuel that forms the turbulence flows into the combustion chamber of the internal combustion engine 1 (not shown), and the explosion generates power.

Further, since the vane 12 is provided with a plurality of convex portions 121 such that the fuel flows between the two convex portions 121 or bypasses the convex portion 121, the fuel is branched by the convex portion 121, and the branched fuel is convex. The side effects of the portion 121 further change the flow field pattern to generate more spoiler. Thus, a blade 12 having two projections 121 can produce at least three splits, each of which forms a turbulent flow. In other words, the more the number of the convex portions 121, the more eddy currents are formed, and the fuel is more efficient in combustion.

In addition, it can be seen from the above that the edge line of the convex portion 121 can have various types of changes, and the edge of the different types of edges can change the rotation angle of the fuel spoiler, and can provide different spoiler effects. As shown in FIG. 3, the convex portion 121 has a circular arc curve, which provides a plurality of contact angles of the fuel compared to the zigzag shape, so that the rotation angle of the fuel is different. As shown in FIG. 4, the size of the convex portion 121 is different, so that the contact area between the fuel and the two convex portions 121 is different, and different rotation angles and spoiler sizes are also caused. In addition, the zigzag-shaped convex portion 121 may also be provided with a lead angle (not shown) at its edge to change the contact angle between the fuel and the convex portion 121, thereby changing the spoiler effect.

As can be seen from the above, the internal combustion engine gasket 1 of the present invention provides a plurality of types of blades 12, and the manufacturer can select the type and number of the convex portions 121 and the angle of the blades 12 in accordance with the required horsepower and efficiency of the internal combustion engine 9.

In summary, the internal combustion engine gasket of the present invention has at least the following advantages: the ribs between the oil inlet holes are used to extend the blades, so that the incoming air and the fuel generate eddy currents, thereby improving the overall combustion efficiency; and the convex ends are provided by the blade edge edges. Different eddy current effects; using the block corresponding to the fuel injection port of the internal combustion engine to atomize the fuel and improve the combustion efficiency.

The above are only the preferred embodiments of the present invention, and all changes and modifications made to the scope of the present invention should be within the scope of the present invention.
