Abstract

The utility model relates to an internal combustion engine intake air filter, which includes filter materials and a filter clogging frame. The filter materials includes a spongy layer and a filter sheet layer. The filter clogging frame consists of a frame and a front-end tablet with an opening. The frame includes a streamside, an outward extension fore end surface coming from side anterior opening and inward extension rear face from rear side opening. The two openings are of the same size and shape. The fore end surface and fore end tablet which are closely connected have the same periphery. The filter materials are filled in the frame and placed in the gap between the fore end surface and the rear end surface. The utility model has advantages of simple assembling, high filtering efficient, convenient cleaning and longer durability.

Description

A kind of internal combustion engine intake filter

Technical field

The utility model relates to a kind of internal combustion engine component, and more particularly, the utility model relates to a kind of accessory of car combustion engine induction part.

Background technique

Combustion in IC engine fuel oil or combustion gas produce heat and expanding gas, promote the piston acting and produce the power that automobile advances.And the burning of gasoline or combustion gas needs the important source material of a large amount of cleaned airs as burning, totally be not mixed with dust impurity if enter the air of internal-combustion engine, gently then influence combustion efficiency and engine power, heavy then cause the automobile engine cylinder-body inwall to damage even burn, cause the accident and economic loss.For this reason; people are equipped with air intake filter at the suction port of internal-combustion engine; after making the air that enters through the filter material of filter and mesh the interception of dust impurity on filter material and mesh and unlikely entering in the cylinder, thereby it is to improving engine efficiency, protecting the effect of motor.

But, present internal combustion engine intake filter or adopt corrugated Stainless Steel Cloth or adopt corrugated filter fiber to bring the dust granule of interception in the air inlet, the former is converted into waveform with Stainless Steel Cloth and in the plastic frame that fixedly is injection-moulded in, this structure complex manufacturing, and for cleaning Stainless Steel Cloth inconvenience, because it is very fastening that dust granule combines with Stainless Steel Cloth, depend merely on washing and can't know totally, take mechanical force or high temperature can damage plastic frame and even Stainless Steel Cloth again; The latter's filter fiber band, improve interception efficient though can on the filter fiber surface, adhere to oil film to the dust granule in the air inlet, can take special cleaning solvent earlier oil film to be dissolved during cleaning, the dust granule that will adhere to washs then, but single filter fiber band quality weakness, cleaning process is damaged easily, and working life is not long.

Summary of the invention

At the above-mentioned shortcoming of prior art, the technical purpose that the utility model will reach is that a kind of internal combustion engine intake filter will be provided, and it has following advantage: assembling is made simple, the filter efficiency height, is convenient to clean and longer service life.

For this reason, technical solution of the present utility model is a kind of internal combustion engine intake filter, it comprises filter material, filter frame, and described filter material comprises spongy layer and filter mesh layer, described filter frame comprises framework and has the preceding dististyle of opening, described framework comprises side, from the outside front-end face that extends of the opening in side the place ahead with from the inside ear end face that extends of the opening at side rear, the size and dimension of the opening of dististyle is identical with the opening of described ear end face before described, the size and dimension of the periphery of dististyle is identical with the periphery of described front-end face before described, and described preceding dististyle is close to described front-end face and is connected, and described filter material is filled within the described framework and is clamped between the space of described preceding dististyle and described ear end face.The utility model adopts one-time formed framework and has the filter frame of open front sheet, framework around utilizing, preceding dististyle and ear end face formation space filter material that spongy layer and filter mesh layer are formed at interval be limited to wherein, assembling manufacturing need not adopted the compound injection moulding between plastics and wire netting, only need preceding dististyle is closed up, is fixed on the framework and gets final product, before dististyle and fixed frame all only need to pass through simple punching press or weldment and make again luggage in advance and join, technology is simple; Stainless filter mesh layer plays the skeleton function of support for spongy layer, cleans to improve filter efficiency and to be convenient to and can adhere to oil film on the sponge fiber of oleophylic, can increase working life.

For further optimizing the basic characteristics of the utility model method, improvement of the present utility model also comprises:

Described filter also comprises the large-meshed net compartment, and described spongy layer is clamped between described filter mesh layer and the large-meshed net compartment.

Described spongy layer fiber surface also is attached with one deck oil film.

Dististyle and described front-end face are to be close to by circumferential uniform a plurality of removable fasteners or continuous bayonet socket to be connected before described.

It is above and folded mutually at interval that described spongy layer and filter mesh layer are one deck.

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
