Abstract

(57) [Summary] [Problem] To provide an air cleaner for an engine that can be housed in a genuine existing air cleaner casing even if the capacity of the filter element is increased, and has a high air intake rate. SOLUTION: An upper casing 3a and a lower casing 3b are detachably attached to each other, the casing has an air inlet 5 and an air outlet 6, and the air inlet 5 and the outlet in the casing are provided. In the air cleaner having the filter element 1 between the upper casing 6 and the lower casing 3a having the air inlet 5, the upper casing 3a is removed, and formed on the entire upper opening of the lower casing 3b so as to match the opening periphery of the lower casing 3b. A planar filter body in which the filter element 1 is stretched and held on a frame body is mounted.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

  The present invention relates to an air cleaner for an automobile engine.

[0002]

[Prior art]

  Generally, in multiple passenger car models manufactured by each manufacturer, Air cleaners of uniform shape and structure are often used. This is Equipped with the same type of engine in several vehicle models, parts are shared between multiple vehicle models and manufactured. This is to promote cost reduction and rationalization of parts inventory.

[0003]   However, when an air cleaner that is deeply related to engine performance is shared by multiple vehicle models , If there is a difference in the engine displacement to be applied, the capacity of the air cleaner may be insufficient. In some cases, the performance of the engine cannot be fully obtained.

[0004]   Until the air cleaner capacity is insufficient as described above, or until it does not become insufficient. To deal with engines with air cleaners that are not Large-capacity air cleaners are supplied in the tar parts market.

[0005]   By the way, in order to increase the capacity of the air cleaner, It may be possible to replace the air cleaner with a larger product, but with a larger surface area. The air cleaner that uses a complicated filter element has a flat casing Because the size of the casing and the height of the casing increase, it is necessary to install a ready-made air cleaner. There is a problem that it cannot fit in the storage space.

[0006]

[Problems to be solved by the device]

  In view of such a point, the present invention has the advantage that even if the capacity of the filter element is increased, Can be stored in the existing car air conditioner casing, and An object of the present invention is to provide an air cleaner for an engine having a high intake rate.

[0007]

[Means for Solving the Problems]

  The structure of the present invention made to solve the above-mentioned problems is an upper casing. The lower casing and the lower casing so that they can be separated and joined together, and the Having an inlet and an air outlet, and between the air inlet and the outlet in the casing In an air cleaner equipped with a filter element, an upper part having an air intake Remove the casing and place the lower casing on the entire upper opening of the lower casing. The filter element is stretched on the frame formed to match the rim of the opening of the housing It is characterized in that the planar filter body held by the above is attached.

[0008]   In the above air cleaner of the present invention, the frame body in which the filter element is stretched is used. , The lower surface side is shaped so that it can be fitted exactly to the upper opening surface of the lower casing However, the detachability is improved.

[0009]

【Example】

  Next, an embodiment of the air cleaner of the present invention will be described with reference to the drawings. Figure 1 shows the air cleaner of the present invention. FIG. 2 is a vertical cross-sectional view schematically showing the main part of an example of an inverter, and FIG. It is a longitudinal cross-sectional view schematically showing an example of an cleaner.

[0010]   Figure 2 shows an example of an existing air cleaner installed in the engine room. Here, 1 is a filter element, 2 is the element around the outer periphery of the element 1. It is integrated with this element 1 to retain its shape and to fix it in the casing 3. It is an edge formed as described above.

[0011]   The filter element 1 is a sheet-shaped filter material made of non-woven fabric, etc. It is bent to form a continuous body of folds 1a and has a large surface area. The plane shape of is usually rectangular. And on the outer periphery of this filter element 1 Holds the shape of the filter element 1 and attaches it to the casing 3, An edge 2 having a substantially inverted L-shaped cross section is provided around the edge 2.

[0012]   The filter element 1 having the edge portion 2 formed on the outer periphery has two filter elements, one on the upper side and one on the lower side. Division of casing 3 formed in upper casing 3a and lower casing 3b of split structure On the faces 3c and 3d, in the clamped portion 2a formed in a flange shape around the entire edge portion 2 thereof, It is clamped and the divided surfaces 3c and 3d are tightened by clips, mounting screws 4, etc. It In addition, 5 is an air intake formed in the upper casing 3a, 6 is a lower casing material It is an air outlet formed in 3b.

[0013]   With the above structure, the casing 3 of the air cleaner is provided with the filter element 1. Via the air intake port 5 into the upper casing 3a. The sucked outside air is filtered by the filter element 1 and is introduced into the lower casing 3b. Supplied, through the air outlet 6 through the air flow meter, or the air flow meter It is supplied to the carburetor etc. without passing through.

[0014]   Therefore, in the present invention, the filter in the above-mentioned manufacturer's genuine off-the-shelf air cleaner is used. By increasing the depth of the folds 1a of the element 1, the filtration area is The outer shape as an air cleaner while enlarging the air intake The size of was approximately the same as the ready-made product of FIG. That is, in the present invention, the lower case Has a flange portion 7a fitted to the inner edge of the ring 3b in the lower portion, and the element is provided on the inner peripheral surface of the intermediate portion. A frame body having an element 1 formed with an inner peripheral groove portion 7b for fitting and holding the edge 2 of 7 as a planar filter body, instead of the above upper casing 3a, a lower casing 3b It was attached to the upper opening of the. In addition, 8 covers the upper surface of the element 1. Protective cover made of coarse mesh material, 9 is a lower case provided on the outer surface of the frame body 7. Clip for holding the connection between the ring 3b and the frame body 7, 10 is the edge 2 fixed to the frame body 7 It is a pin for.

[0015]   With the above structure, in the air cleaner of the present invention, the upper opening of the lower casing 3b is opened. Of the air cleaner acts as an air intake, and the overall height of the air cleaner is Since the part casing 3a becomes lower by the amount removed, the surface area is larger than that of ready-made products. The ment 1 will inhale air over its entire surface.

[0016]

[Effect of device]

  As described above, the air cleaner of the present invention has an upper casing and a lower casing. It can be separated and attached freely, and has an air inlet and an air outlet in the casing. And a filter element between the air inlet and outlet in the casing. In the provided air cleaner, remove the upper casing with the air intake Cover the entire upper opening of the lower casing with the peripheral edge of the opening of the lower casing. A sheet-like filter with a filter element stretched and held on a frame formed to fit The existing lower casing for the air cleaner has been replaced by installing the filter body. It can be used as it is, and the capacity of the air cleaner can be increased. Therefore, the same air cleaner is used regardless of the engine displacement. Providing a low-cost air cleaner with a capacity corresponding to the displacement of gin You can do it.
