[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air cleaner for an automobile engine.

[0002]

2. Description of the Related Art In general, in a plurality of types of passenger cars manufactured by various manufacturers, an air cleaner having a uniform shape and structure among several types of vehicles is often used. The aim is to make parts common among multiple models, to reduce manufacturing costs and rationalize parts inventory.

[0003] However, if an air cleaner that is deeply related to the engine performance is shared among a plurality of vehicle types, the engine capacity may be insufficient due to the small size of the engine in some engines due to the size of the engine displacement. May not be able to be withdrawn.

[0004] In view of such a point, air cleaners having a large capacity are supplied in the parts market for engines in which the capacity of the air cleaner is insufficient or not enough if not insufficient.

However, in order to increase the capacity of the air cleaner, that is, to increase the surface area of the filter element, for example, the height of the zigzag cross section of the filter element (for example, with the outer contour being the same as the existing filter element). When only the depth is increased, the overall height of the filter element becomes large, so that there is a problem that the filter element cannot be accommodated in an existing housing or casing containing a ready-made filter element.

[0006]

SUMMARY OF THE INVENTION In view of the above, the present invention increases the air intake area by, for example, 50% of the existing product while keeping the outer shape of the filter element as viewed from the plane, thereby reducing the size of the filter element. It is an object of the present invention to provide an air cleaner for an engine that can be accommodated in an existing air cleaner housing or casing even when the overall height of the element increases.

[0007]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and has a configuration in which a filter element having a suction surface formed in a zigzag cross section is shaped around its outer periphery and supported by a casing. A filter member provided with an edge formed of a rubber-based material or the like provided around the filter element, and a box-shaped container of an upper and lower split type, wherein an intake port is formed on one side and an air supply port is formed on the other side. In an engine air cleaner comprising a casing configured to sandwich the edge on a divided surface, in place of the filter member, an outer shape as viewed from a plane is the same as the filter element, and a cross section is formed in a bulky manner. The portion of the edge formed on the outer periphery of the filter element, which is held between the divided surfaces of the casing, is the edge of the filter member. It is characterized in a filter member formed more thick that it has to be attached to the casing.

[0008]

Next, an embodiment of the air cleaner according to the present invention will be described with reference to the drawings. FIG. 1 is a longitudinal sectional view schematically showing a main part of an example of the air cleaner of the present invention, and FIG. 2 is a longitudinal sectional view schematically showing an existing air cleaner.

FIG. 2 shows an example of the structure of an existing air cleaner provided in an engine room. Reference numeral 1 denotes a filter element. Reference numeral 2 denotes an outer shape of the element 1 and the shape of the element 1 is stored and fixed in a casing 3. This is an edge formed so as to be integrated with the element 1.

[0010] The filter element 1 is made of a sheet-like filter material made of non-woven fabric or the like.
The intake surface is formed so as to have a large surface area by being bent so as to form a, and its planar outer shape is usually rectangular. An edge 2 having a substantially L-shaped cross section is provided around the outer periphery of the filter element 1 for maintaining the shape of the filter element 1 and mounting the filter element 1 to the casing 3.

[0011] The filter element 1 having the edge 2 formed on the outer periphery is divided into upper and lower split casings 3c and 3d formed on the upper casing member 3a and the lower casing member 3b. The entire surface of the edge 2 is clamped by a clamped portion 2 a formed in a flange shape, and the divided surfaces 3 c and 3 d are tightened by a clip 4. In addition, 3e is an air inlet formed in the upper casing material 3a, and 3f is an air inlet formed in the lower casing material 3b.

With the above configuration, the casing 3 of the air cleaner is divided into upper and lower parts via the filter element 1, so that the outside air sucked into the upper casing member 3a from the intake port 3e is filtered by the filter element 1. Is supplied to the lower casing material 3b and the air supply port 3f
From the carburetor.

According to the present invention, the filtering area of the filter element 1 in the air cleaner is made larger than that of FIG. 2 and the size of the outer shape is equal to that of FIG. Is formed to have a large height. When the height h of the fold continuum 1a of the element 1 is increased, the shoulder of the edge 2 hits the inner surface of the casing 3 and does not fit inside the casing 3 as it is.

Therefore, in the present invention, as shown in FIG. 1, at the edge 2 formed on the outer periphery of the element 1 in which the height h1 of the pleated body 1a is increased (height h2), the divided surfaces 3c and 3d of the casing 3 are formed. The thickness of the portion to be clamped 2a to be clamped (thickness t2) was formed.

Then, the clamped 2 whose thickness is increased to t2
As a is sandwiched between the divided surfaces 3b and 3c of the casing 3, the inner effective height of the upper and lower casing members 3a and 3b is raised by an amount corresponding to the increase in the thickness of the clamped portion 2a from t1 to t2. Therefore, the height of the fold 1a is h
The element 1 having an increased surface area from 1 to h2 can be housed in the casing 3 as it is. As the clip 4 'for sandwiching the divided surfaces 3c and 3d from the outside, a clip larger than that shown in FIG. 2 is used in response to the increase in the thickness of the held portion 2a.

[0016]

[Effect of the Invention] As described above, the air cleaner of the present invention is:
By increasing the height of the fold and increasing the filtration area without changing the size of the outer shape as viewed from the plane of the cleaner element, and increasing the wall thickness of the portion of the edge sandwiched by the casing, Since the capacity of the air cleaner can be increased by using the casing without replacing the casing, the air cleaner of the capacity corresponding to the displacement is used for the engine using the same air cleaner regardless of the displacement of the engine. Can be provided at low cost.
