[Field of design]

The present invention relates to a head gasket for an internal combustion engine, and more particularly, to a head gasket capable of actively blocking leakage of compressed gas by increasing rigidity and airtightness.

[Private Technology]

An internal combustion engine is a prime mover that burns fuel inside a cylinder and outputs pressure generated in its combustion process as a rotational power. An example thereof is an automobile engine.

In the operation process of such an internal combustion engine, an intake stroke that sucks external air and fuel, a compression stroke that compresses the inhaled air, and a combustion stroke that discharges sparks by igniting and exploding a flame in a compressed mixer, and an exhaust stroke that discharges the burned gas Operation is performed in 1 cycle through 4 strokes.

In the above operation process, a high pressure (at least 45 kg / cm 2 or more) is applied to the inside of the combustion chamber during the compression stroke and the explosion stroke, and a head gasket is interposed between the cylinder block and the cylinder head to prevent the pressure from leaking. .

Since the head gasket is required to be insulated and pressure resistant, asbestos is wrapped in a copper plate or a steel plate, and the conventional head gasket is wound asbestos 102 by the copper plate 100 and the steel plate 101 as shown in FIG. It was common to form a stacking form by bending the lower steel sheet 101 in a state where the wire 103 is arranged at the edge thereof.

However, in the head gasket as described above, when the head bolt is tightened as a whole, the fixing is performed. Therefore, when the head bolt is tightened evenly, the compressed gas leaks even if the head bolt is unevenly tightened even a little.

[Intention summary]

Therefore, the present invention has been devised to solve the above-mentioned conventional problems, and an object of the present invention is to provide a head gasket for an internal combustion engine that can increase the robustness and airtightness and actively block the leakage of compressed gas.

In order to realize this, the present invention provides a head gasket of an internal combustion engine including a core member, a top and bottom exterior members, and a finishing member coupled to an edge portion.

The concave part is formed in the upper and lower parts of the core part of the central part so that the outer plate member is covered on the upper and lower sides of the core, and the outer edge of the bore part is covered with two wires arranged in the upper and lower parts, and the finishing member is moved outward. The outer edge provides a head gasket for an internal combustion engine, wherein the outer edge has a wire on the upper and lower sides, and an outer plate member is covered on the upper and lower sides, and the finishing member is coupled to the edge thereof.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention capable of realizing the above object in detail as follows.

EXAMPLE

1 to 4 show a preferred embodiment according to the present invention, wherein 1 denotes the entire head gasket.

The head gasket 1 is provided with various passages such as a cylinder bore, a coolant passage, an oil passage, etc., but only the cylinder bore through hole 3, which is the most airtight portion, is shown in the present invention.

The head gasket 1 has a core 5 in the center and is disposed on the outer plate members 7 and 9 on its upper and lower sides, and a finishing member 11 is formed at each hole.

As described above, the core 5 may use asbestos as in the related art, but a metal plate having low hardness may be used, and the outer plate members 7 and 9 may be formed of a steel plate and a copper plate, and the finishing member 11 may be a steel plate. Although it is preferable to form, it is not limited to this, You may form from another material according to the characteristic of an engine.

In this head gasket (1), the present invention provides a recess 13 in the upper and lower portions of the core 5 of the central portion between the cylinder bore and the bore to place the wire 13 thereon. The outer plate members 7 and 9 are covered with the upper and lower sides, and the outer edge of the bore portion is covered with the outer plate members 7 and 9 with two wires 15 and 17 arranged at the upper and lower portions thereof. The finishing member 11 was combined.

Accordingly, the bore and the bore are formed in a two-stage structure, and at the edges of the head gasket 1, wires 19 are placed on the upper and lower portions as shown in FIGS. ) Is covered, and the finishing member 11 is joined to the edge thereof.

As described above, the wires 13, 15, 17, and 19 are disposed on the upper and lower portions of the core 5, respectively, and the outer plate members 7 and 9 are covered, and the edges are joined by the finishing members 11, respectively. Since the portions where the wires 13, 15, 17, and 19 are disposed protrude outwards, the portions are pressed while the head bolts are tightened, and the entire compression is performed.

Accordingly, in the state where the head gasket 1 is uniformly compressed as a whole, the portion where the wires 13, 15, 17, and 19 are disposed is pressed with a greater force to maintain airtightness. The bore edge is held in three stages by two wires 15 and 17, so that the airtightness is very excellent.

As described above, according to the present invention, it is made of a metal and improves the rigidity, and the head gasket is a useful design that can actively block the leakage of compressed gas by maintaining the airtight of two or three stages as a simple structure.

Claims (1)
