The inner case 240 is configured to be coupled to the outer case 140, but specifically coupled to the lower end of the inner case 240 and the lower end of the outer case 140, a separate lower fastening portion (not shown) It can be configured to be fastened by). Since the inner case 240 and the outer case 140 are coupled to each other and fastened, even if air is rotated in the inner case 240 and a force is applied to the filtration unit 250, the outer case 140 is provided. Alternatively, the inner case 240 should not be separated or damaged.

In addition, a separate upper fastening part 260 may be configured at an upper center of the inner case 240. The upper fastening part may be configured to fasten the inner case 240 and the filtration part 250, and may be configured to include the inner case 240, the filtration part 250, and a housing (not shown). Can be.

The upper fastening part 260 may be composed of a pipe-type fastening bolt 265 and a nut 261, and the pipe-type fastening bolt 265 may be configured of a pipe type through which the upper and lower sides pass.

In this patent, in the upper fastening part, the fastening bolt is configured in a pipe shape through which the upper and lower sides are to fasten the internal combustion engine together with the inner case 240 and the filtration part 250. It is intended to be compatible with various types of internal combustion engine. If the fastening bolt is configured in such a manner that the upper and lower portions do not penetrate, the fastening of the fastening bolt may be a problem in that the fastening is not compatible with various types or various types of internal combustion engines.

However, if the fastening bolt is configured in a pipe shape through which the upper and lower penetrates, it may be possible to solve the impossible problem even if it is an internal combustion engine of various types or various types.

On the other hand, since the upper end and the lower end of the filtration unit 250 are fastened, the filtration unit 250 will not be separated or damaged, but the middle portion of the filtration unit 250 may depend on the flow rate of air. 250 may be deformed or damaged, such as an increase. Therefore, in the present invention, in order to prevent the filter unit 250 from being separated or damaged, it may be preferable that a support is further configured between the outer case 140 and the inner case 240. That is, a connection case 340 may be added between the outer case 140 and the inner case 240 to prevent deformation or damage of the filtration unit 250.

In the present invention, a bypass flow path D is formed on a side surface of the inner case 240 so that air supplied from outside passes through the outer case 140 and the inner case 240, or the outer case ( The contaminated outdoor air may be purified while passing through the 140 and the inner case 240 and the connection case 340.

In particular, the cleanable air cleaner device for an internal combustion engine of the present invention may be formed by expanding the air flow path by the bypass passage D formed according to the bending of the filtration unit 250, or purifying the air rotation path by further variously forming it. The effect can be enhanced.

Referring to FIG. 2, the process of purifying air and the effects of the bypass flow path D are as follows. First, the air supplied from the outside is introduced into the air cleaner device 200 through the through hole 141 of the outer case 140 of the air cleaner device for internal combustion engine 200. At this time, it can be purified while passing through the lower portion of the A portion and the protrusion 240 of the filtration unit 250 that is in contact with the outer surface of the outer case 140 (first path (①)).

If foreign matter is caught in the filtration unit 250 on the first path ① during this purification process, negative pressure is applied, and the air is formed at the upper end of the outer case 140 and the outer side of the upper end of the inner case 240. It can be purified while passing through the portion B of 250 and the through hole 241 of the inner case 240 (second path (②)).

When foreign matter is collected in the corresponding filtering part 250 of the first path ① and the second path ② and negative pressure is applied, air is interposed between the upper end of the outer case 140 and the outer surface of the inner case 240. Can be purified while passing through the C portion of the filter portion 250 and the through-hole 241 of the lower end of the inner case 240 is configured (third path (③)).

In addition, referring to FIG. 3, the process of purifying air and the effects of the bypass flow path D are as follows. The first path ① of FIG. 3, or the second path ② of FIG. 3 may be substantially the same as the first path ① of FIG. 2, or the second path ② of FIG. 2, but FIG. 3. The third path of (③) will be as follows. That is, the air introduced from the outside is formed through the C portion of the filter part 250 formed at the upper end of the connection case 340 and the through hole 341 of the connection case 340 and the through hole of the lower end of the inner case 240 ( It may be purified while passing through 241 (called third path (③)).

In addition, referring to FIG. 2 or FIG. 3, the effects of the bypass flow path D of air are as follows. In the present invention, the bypass flow path D may be induced by the B section of the inclined filtration unit 250 or the C section of the inclined filtration unit 250. The rotational movement can also be performed by the pass flow path.

When formed in the first path (①), the second path (②), or the third path (③), foreign matters having a large particle size may be included in the outside air. 250 may be collected in the A portion, or fine foreign matter may be collected while passing through the B portion of the filter unit 250, or fine foreign matter may pass through the C portion of the filter unit 250 Can be collected, but may be slightly different.

In addition, the air passing through the inner case 240 may be discharged to the combustion chamber through the air vent 260 formed under the inner case 240.

In addition, the pipe-type fastening bolt 265 configured in the center of the upper end of the inner case 240 may be fastened with a nut 261 that is configured to fasten the upper end of the inner case 240 and the upper end of the filtration unit 250. have.

In addition, in order to fasten the lower end of the outer case 140 and the lower end of the filtration unit 250 may be fastened by a fastening device portion 295 configured separately from the lower end of the outer case 140.

The filtration unit 250 may be formed of one layer or two or more layers of nonwoven fabric. Using multiple layers may be to increase the effect of air purification. That is, in the case of a paper filter, multiple bonding is difficult and the breathability is deteriorated at the time of bonding, while the filter unit 250 used in the present invention is easy to carry out multiple bonding by using a nonwoven fabric and improves dust collection effect, and maintains breathability even when used for a long time Can be.

In addition, according to the type of internal combustion engine (engine), it is natural that the number of layers of the nonwoven fabric or the thickness of the nonwoven fabric can be freely configured, and the appropriate material selection can be variously configured.

In addition, after operating the internal combustion engine for a predetermined time or more, it may be possible to continuously use the air cleaner 200 by replacing only the filtration unit 250. In addition, the nonwoven fabric used as the material of the filter unit 250 may be a general nonwoven fabric, but it may be preferable to use a nonwoven fabric having electrostatic properties.

5 is a view illustrating a separated state of the filtration unit 250 used in the air cleaner 200 for an internal combustion engine according to the present invention. Referring to FIG. 5, the A portion of the filtration unit 250 covers the outer surface of the outer case 140, and the B portion of the filtration unit 250 covers the outer surface of the inner case 240. Cover portion, the C portion of the filter unit 250 may be configured to cover the outer surface of the outer case 140 and the outer surface of the upper end of the inner case 240.

In the present invention, the filtration unit 25 may be configured to expand the area through which the incoming air passes. That is, the filtration unit of the present invention can extend the filtration area to the A portion of the filtration unit 250, the B portion of the filtration unit 250 and the C portion of the filtration unit 250, thus, the filtration area expansion Due to the breathability and purification effect can be maximized.

The gas introduced from the outside is collected while relatively large foreign matter is passed through the A portion, and is rotated in the bypass flow path D, which is a space between the B and C, and is purified while passing through the C portion of the filtration unit 250. In Part B, relatively small foreign matter is collected. The C portion of the filtration unit 250 is relatively clean in use compared to other portions, because the air inside the inner case 240 is purified through the B portion while being moved to the center while rotating in rotation.

According to the above-described air cleaner device for an internal combustion engine, due to the action of the bypass flow path (D), it is possible to supply a sufficient amount of air required for the combustion chamber, thereby maintaining the best fuel economy by completely burning the compressed injection fuel.

On the other hand, the material constituting the inner and outer cases can be varied, and may be made of aluminum or synthetic resin material to reduce the weight.

In addition, the air cleaner device for an internal combustion engine according to the present invention has excellent air permeability, excellent dust collection effect, and a long filtration life of the filtration unit by using a bypass flow path. In addition, it is economical because it can be reused by washing the filter, there is always an advantage that can be used as new.

On the other hand, when the internal combustion engine is stopped, since some of the combustion chambers constituting the internal combustion engine may be open, oil may be discharged from the inside of the combustion chamber to the outside. For example, when a four-cylinder internal combustion engine is stopped, one combustion chamber may be located on the upper side, the other combustion chamber on the lower side, and the other two combustion chambers may be located on the upper side and the lower side. Therefore, when the internal combustion engine is stopped, it may be possible to open some of the combustion chambers and to discharge oil from the open combustion chambers.

In the present patent, in the filtration unit used for the air cleaner for the internal combustion engine, the filtration unit filters out foreign matter and fine dust that may be included in the air introduced from the outside, and removes water that may be included in the air, particularly, introduced air. It may be composed of a first filtration unit 251. Or it may be composed of a second filtration unit 252 for removing foreign matter, fine dust that may be included in the air introduced from the outside. Or it may be composed of a third filtration unit 253 for removing the oil (oil vapor) that can be discharged from the internal combustion chamber.
