Description

[0001]
[Industrial application fields]
In an engine air cleaner, the present invention relates to an engine air cleaner cover configured to protect a filter element without reducing intake efficiency and to be easily installed.
[0002]
[Prior art]
As an example of an air cleaner for an engine, as shown in the assembly diagram of FIG. 6, a filter element 4 formed in a cylindrical shape with porous foamed urethane or the like in which bubbles communicated is provided at the intake port so that the filter element 4 The dust is removed.
[0003]
In this type of engine air cleaner, a filter element 4 is mounted on a pedestal 3 having a vent hole 32 connected to an intake manifold via a cylindrical connecting member 2, and a ring-shaped mounting bracket is mounted on the top of the filter element 4. The filter element 4 is fixed by applying a coiled spring 6 between the cut and raised piece 51 of the ring-shaped mounting bracket 5 and the cut and raised piece 31 formed on the base 3.
[0004]
This filter element 4 has a cavity 42 communicating with the vent hole 32 of the pedestal 3 (see FIG. 3), and a spiral irregularity 41 is formed around it to increase the surface area.
[0005]
Then, when the filter element 4 is clogged and the air permeability is deteriorated, the coiled spring 6 and the ring-shaped mounting bracket 5 are removed, and the filter element 4 is removed and cleaned or replaced.
[0006]
[Problems to be solved by the invention]
The conventional air cleaner is installed in a place where the temperature is relatively low with the filter element 4 exposed in the engine room, and functions to remove dust.
[0007]
Since the exposed filter element 4 is deteriorated by the radiant heat radiated from the engine, the filter element 4 is covered with a cover.
[0008]
However, when the filter element 4 is covered with a cover, the intake efficiency tends to be reduced, or dust tends to concentrate and accumulate on a specific portion of the filter element 4.
[0009]
Therefore, the present invention was conceived to provide an air cleaner cover for an engine that is easy to attach without lowering the intake efficiency of the filter element even if the filter element is covered with a cover. .
[0010]
[Means for Solving the Problems]
The engine air cleaner cover of the present invention has an opening 13 for taking in air and a narrow opening 14 for placing on the pedestal 3 and protects the side of the filter element 4 formed in a cylindrical shape by porous foamed urethane or the like. a 1, Rutotomoni provided a helical fins 11 which rectifies the air inside the cover 1, and a hole 12 in the side surface of the cover, fit the ring-shaped mounting bracket 5 on top of the filter element 4, the cover 1 The filter element 4 and the cover 1 are fixed to the pedestal 3 by applying a coiled spring 6 between the ring-shaped mounting bracket 5 and the pedestal 3 through the holes 12.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of an air cleaner cover for an engine according to the present invention will be described below in detail with reference to the accompanying drawings.
[0013]
As shown in the longitudinal sectional view of FIG. 1, the engine air cleaner cover according to the present invention covers the side of the filter element 4 and is a metal plate that is easy to draw, such as aluminum that reflects radiant heat. A trumpet-shaped cover having a wide opening 13 serving as an air inlet and a narrow opening 14 mounted on the pedestal 3, and a plurality of spiral fins 11 are provided on the inner surface of the cover 1. A hole 12 through which the coiled spring 6 is inserted is formed in the side surface.
[0014]
The spiral fin 11 is formed by processing an elongated metal plate such as aluminum so that it is positioned between the filter element 4 and the cover 1 when assembled. It is fixed.
[0015]
The engine air cleaner to which the cover of the present invention is applied has a ventilation hole 32 coupled to the intake manifold via a cylindrical coupling member 2 as shown in the assembly diagram of FIG. 2 and the longitudinal sectional view of FIG. The filter element 4 is placed on a pedestal 3 having a cover, and the cover 1 is placed on the pedestal 3 so as to cover the side of the filter element 4 with the cover 1. The filter element 4 and the cover 1 are attached to the coil-shaped spring 6 between the cut-and-raised piece 51 of the ring-shaped mounting bracket 5 and the cut-and-raised piece 31 of the pedestal 3 through the hole 12 formed in the side surface of By fixing to the base 3, it assembles as shown in the side view of FIG. 4 and the top view of FIG.
[0016]
Thus, in the engine air cleaner using the porous foamed urethane filter element 4, the cover 1 is not attached to the filter element 4, but the user can easily attach the cover 1.
[0017]
When the engine air cleaner configured as described above is used and the engine is started and sucked in, the filter element 4 sucks the surrounding air, but the cover 1 having the spiral fins 11 is provided. Therefore, the air taken in from the opening 13 of the cover 1 is rectified by the spiral fin 11 and sucked into the filter element 4 while turning.
[0018]
【The invention's effect】
As is clear from the description based on the above embodiments, according to the present invention, the side portion of the filter element 4 is covered with the cover 1, so that the opening 13 of the cover 1 is installed in the direction of lower temperature. Thus, it is possible to suck in low-temperature air, and by providing spiral fins 11 inside the cover 1 to rectify the suction air in a spiral manner, the filter element 4 can be uniformly distributed over the entire surface. Intake can be performed, and the intake efficiency can be increased without clogging.
[0019]
Furthermore, when the cover 1 is attached to a conventional engine air cleaner, the coil spring 6 can be used as it is, and the cover 1 and the ring-shaped mounting bracket 5 can be attached, so that no parts other than the cover 1 are required. In addition, since no special processing is required, the user can easily attach the cover 1 himself / herself.
