The present application claims priority to Korean Patent Application No. 10-2021-0179026, filed Dec. 14, 2021, the entire contents of which is incorporated herein for all purposes by this reference.
The present disclosure relates to an intake system of a vehicle. More particularly, the present disclosure relates to an intake system of a vehicle, the intake system being capable of maximally preventing moisture and foreign substances from entering an air cleaner, and being capable of realizing a simplified configuration by having an integrated-type structure.
An intake system of a vehicle is a system configured to supply fresh air (clean air), which is outside air having foreign substances removed therefrom, to a combustion chamber of an engine, and includes an intake duct (air duct), an air cleaner, and an intake hose (air hose).
When moisture (water) is introduced into the air cleaner of the intake system, a situation in which not only damage to the intake system occurs but also damage to the engine occurs in a severe situation occurs. Therefore, to prevent the present situation, a new type of an intake system layout structure is required.
In Southeast Asia, which is a tropical rain forest region, the average annual amount of precipitation is larger than that of other regions, so that a situation in which vehicles are fording on rivers, streams, and the like is frequently occurs. At the instant time, to secure fording ability of a vehicle, a situation in which moisture (water) is introduced into an air cleaner is required to be maximally prevented. Therefore, a new type of an intake system layout structure capable of preventing introduction of moisture is required.
Furthermore, a conventional intake system is configured so that an intake duct, an air cleaner, and an intake hose are individually formed and then are connected to and coupled to each other, which has disadvantages of causing an increase in man-hours and an increase in manufacturing cost.
The information included in this Background of the Invention section is only for enhancement of understanding of the general background of the invention and may not be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person skilled in the art.
Various aspects of the present disclosure are directed to providing an intake system of a vehicle, the intake system being configured for maximally preventing moisture and foreign substances from being introduced into an air cleaner, and the intake system being configured for increasing fording ability of the vehicle when the intake system is used especially in a tropical rain forest region, such as Southeast Asia, including a large amount of precipitation.
Furthermore, various aspects of the present disclosure are to provide an intake system of a vehicle, the intake system being configured in a structure in which an intake duct and an air cleaner are formed integrally with each other or being configured in a structure in which the intake duct, the air cleaner, and an external resonator are formed integrally with each other, realizing a simplified configuration, and a reduction in man-hours and in manufacturing cost.

Furthermore, the air movement path from the entrance of the intake duct portion to the filter may be formed in a shape of “U”.
Furthermore, the intake system may further include an intake shield which is coupled to an entrance of the intake duct portion and which is preventing moisture and impurities from being introduced into the intake duct portion, wherein the intake shield may include a casing portion coupled to the intake duct portion, and may include a grill portion provided in a front surface of the casing portion.
Furthermore, the intake duct portion may be provided with a first internal resonator portion that is formed to expand a space thereof by being connected to the intake duct portion.
Furthermore, the air cleaner body portion may be provided with a second internal resonator portion which is for reducing noise, and a filter mounting portion may be provided above the second internal resonator portion.
Furthermore, an air cleaner body lower cap may be fusion-coupled to a lower end portion of the air cleaner body portion, and a first drain valve for discharging moisture and impurities may be provided at a bottom portion of the air cleaner body lower cap.
Furthermore, the air that has been introduced into the intake duct portion may move downward along the intake duct portion, and then may pass through the filter after passing through the air cleaner body lower cap and the second internal resonator portion.
Furthermore, the intake system may further include a plurality of connection holes that fluidically connects the intake duct portion and the air cleaner body portion from above the air cleaner body lower cap, wherein when water flows backward to the air cleaner body lower cap through the first drain valve, the air that has been introduced into the intake duct portion may move downward along the intake duct portion and then may move to the air cleaner body portion through the plurality of connection holes, and then may pass through the filter by bypassing the second internal resonator portion.
Furthermore, the intake system may further include an external resonator which is connected to the air cleaner body lower cap and which reduces engine noise.
Furthermore, the external resonator may be manufactured as an individual component, and may be coupled to the air cleaner body lower cap.
Furthermore, the external resonator may be formed integrally with the air cleaner body lower cap.
Furthermore, when the external resonator is manufactured as an individual component and is coupled to the air cleaner body lower cap, a rubber seal may be coupled to a portion to which the air cleaner body lower cap and the external resonator are coupled so that airtightness is maintained therebetween.
Furthermore, a second drain valve for discharging the moisture and the impurities may be provided at a bottom portion of the external resonator.

Hereinafter, an intake system of a vehicle according to various exemplary embodiments of the present disclosure will be described with reference to the accompanying drawings.
As illustrated in
The intake duct portion 110 is a configuration corresponding to an intake duct (an air duct) in a conventional intake system, and the air cleaner body portion 120 is a configuration corresponding to a conventional air cleaner body. Conventionally, the intake duct in the conventional intake system and the conventional air cleaner body are each formed individually and are coupled to each other. However, according to an exemplary embodiment of the present disclosure, the intake duct portion 110 and the air cleaner body portion 120 are formed integrally with each other, so that a simplified configuration may be realized and reduction in man-hours and in manufacturing cost may be realized.
As illustrated in
That is, the air movement path from the entrance 111 of the intake duct portion 110 to the filter 200 is a structure in which air is moved along a ‘U’-shaped movement path. Therefore, even if water (moisture) is introduced into the intake duct portion 110 together with outside air, water that has been introduced into the intake duct portion 110 is prevented from moving to the filter 200 of the air cleaner body portion 120. Accordingly, damage to the intake system by water (moisture) may be prevented, and damage to an engine may further be maximally prevented.
Therefore, according to an exemplary embodiment of the present disclosure, the intake system including the ‘U’-shaped movement path may be used more usefully in a tropical rain forest region, such as Southeast Asia, having a large amount of precipitation. Accordingly, fording ability of the vehicle may be increased.
The intake system according to an exemplary embodiment of the present disclosure further includes an intake shield 500 which is coupled to the entrance 111 of the intake duct portion 110 and which prevents moisture and impurities from being introduced into the intake duct portion 110.
The intake shield 500 includes a casing portion 510 coupled to the intake duct portion 110, and includes a grill portion 520 provided in a front surface of the casing portion 510.
The grill portion 520 has a structure in which a plurality of blocking plates is provided in a diagonal direction thereof. Therefore, as illustrated by an arrow M2 in a dotted line, outside air is moved so that the outside air passes through the grill portion 520 and is introduced into the casing portion 510 and the intake duct portion 110. Furthermore, as illustrated by an arrow M3 in a dotted line, most of impurities and water (moisture) included in the outside air are blocked by the grill portion 520 and are not capable of passing through the grill portion 520, so that a situation in which impurities and water (moisture) are introduced into the casing portion 510 may be maximally prevented.
In more detail, a duct cap 140 may be formed integrally with the entrance 111 of the intake duct portion 110 by being fusion-coupled to the entrance 111 of the intake duct portion 110, and a rear end portion of the casing portion 510 may be coupled to a front surface of the duct cap 140.
According to an exemplary embodiment of the present disclosure, the intake duct portion 110 includes a first internal resonator portion 150 that expands a space by being connected to the intake duct portion 110, and intake noise and engine noise may be reduced by the first internal resonator portion 150.
Furthermore, the air cleaner body portion 120 includes a second internal resonator portion 160 configured for reducing the engine noise, and a filter mounting portion 170 in which the filter 200 is mounted is provided above the second internal resonator portion 160.
According to an exemplary embodiment of the present disclosure, an air cleaner body lower cap 600 is fusion-coupled to a lower end portion of the air cleaner body portion 120, and a first drain valve 610 for discharging moisture and impurities is provided at a bottom portion of the air cleaner body lower cap 600.
As illustrated by an arrow M4 in a dotted line in
Furthermore, as illustrated by an arrow M5 in a dotted line in
The neck portion 620 of the air cleaner body lower cap 600 is a portion to which the external resonator 700 is connected.
Meanwhile, according to an exemplary embodiment of the present disclosure further includes a plurality of connection holes 180 that connects the intake duct portion 110 and the air cleaner body portion 120 from above the air cleaner body lower cap 600.
The plurality of connection holes 180 may be formed so that the plurality of connection holes 180 is connected to the air cleaner body portion 120 from the lower end portion of the intake duct portion 110.
When water flows backward to the air cleaner body lower cap 600 through the first drain valve 610, air introduced into the intake duct portion 110 does not move in the same movement path as the above-mentioned arrow M4 due to the water existing in the air cleaner body lower cap 600.
Therefore, when water flows backward to the air cleaner body lower cap 600 through the first drain valve 610, air introduced into the intake duct portion 110 is moved downwards along the intake duct portion 110 as illustrated by an arrow M7 in a dotted line in
That is, the plurality of connection holes 180 functions as a bypass passage that allows air to smoothly move to the air cleaner body portion 120 from the intake duct portion 110 when water flows backward to the air cleaner body lower cap 600 through the first drain valve 610.
The intake system according to an exemplary embodiment of the present disclosure further includes the external resonator 700 which is connected to the air cleaner body lower cap 600 and which reduces the engine noise.
The external resonator 700 is configured to reduce noise generated from the engine, and has a volume thereof much greater than a volume of the first internal resonator portion 150 and a volume of the second internal resonator portion 160.
The external resonator 700 may be manufactured as a separate component and may be coupled to the air cleaner body lower cap 600. In the present situation, the external resonator 700 has a structure in which the external resonator 700 is connected to the neck portion 620 of the air cleaner body lower cap 600. Furthermore, a rubber seal 800 may be coupled to a portion where the air cleaner body lower cap 600 and the external resonator 700 are connected, i.e., the neck portion 620 of the air cleaner body lower cap 600.
The rubber seal 800 is configured to prevent water (moisture) from entering, and may be formed of a material other than rubber.
According to an exemplary embodiment of the present disclosure, a second drain valve 710 for discharging water and impurities is provided at a bottom portion of the external resonator 700.
As illustrated by the arrow M6 in
The external resonator 700 is configured so that the external resonator 700 is connected to a lower portion of the intake duct portion 110. Therefore, when water is introduced into the intake duct portion 110, the water is guided to be moved downwards so that the water is stored in the external resonator 700 or the water is discharged outside through the second drain valve 710.
At the present time, the external resonator 700 simultaneously performs two functions that are a noise reducing function and a water discharging function. That is, during high-speed driving of the vehicle, the external resonator 700 is configured to reduce noise generated from the engine. Otherwise, while driving of the vehicle in a flooded region or in a water transmission pipeline, the fording ability of the vehicle may be increased by discharging water that has been introduced into the intake duct portion 110 to the outside through the second drain valve 710.
According to an exemplary embodiment of the present disclosure, a diffuser 410 connected to the intake hose 300 is formed integrally with the air cleaner cover 400, a third internal resonator 900 is integrally provided at an upper end portion of the diffuser 410, and a resonator cap 910 is fusion-coupled to the air cleaner cover 400 to form a volume of the third internal resonator 900.
Both the diffuser 410 and the third internal resonator 900 are configured to reduce noise. Furthermore, the third internal resonator 900 may be formed integrally with the air cleaner cover 400, or may be separately formed and may be connected to and coupled to the air cleaner cover 400.
As described above, the intake system according to an exemplary embodiment of the present disclosure has a structure in which air moves from the entrance 111 of the intake duct portion 110 into which outside air is introduced to a position where the filter 200 is mounted, along the ‘U’-shaped movement path. Therefore, even if water (moisture) is introduced into the intake duct portion 110 together with outside air, water that has been introduced into the intake duct portion 110 may be prevented from moving to the filter 200 of the air cleaner body portion 120. Accordingly, damage to the intake system caused by water (moisture) may be prevented, and damage to the engine may further be maximally prevented.
Furthermore, the intake system of the present disclosure has a configuration in which the intake duct portion 110 into which outside air is introduced and the air cleaner body portion 120 in which the filter 200 is mounted are formed integrally with each other, and has a configuration in which the external resonator 700 is integrally formed at the air cleaner body portion 120 as necessary. Accordingly, a simplified configuration may be realized, and reduction in man-hours and in manufacturing cost may be realized.
Furthermore, the terms such as “unit”, “module”, etc. disclosed in the specification mean units for processing at least one function or operation, which may be implemented by hardware, software, or a combination thereof.
For convenience in explanation and accurate definition in the appended claims, the terms “upper”, “lower”, “inner”, “outer”, “up”, “down”, “upwards”, “downwards”, “front”, “rear”, “back”, “inside”, “outside”, “inwardly”, “outwardly”, “interior”, “exterior”, “internal”, “external”, “forwards”, and “backwards” are used to describe features of the exemplary embodiments with reference to the positions of such features as displayed in the FIGS.. It will be further understood that the term “connect” or its derivatives refer both to direct and indirect connection.
The foregoing descriptions of specific exemplary embodiments of the present disclosure have been presented for purposes of illustration and description. They are not intended to be exhaustive or to limit the present disclosure to the precise forms disclosed, and obviously many modifications and variations are possible in light of the above teachings. The exemplary embodiments were chosen and described to explain certain principles of the present disclosure and their practical application, to enable others skilled in the art to make and utilize various exemplary embodiments of the present disclosure, as well as various alternatives and modifications thereof. It is intended that the scope of the present disclosure be defined by the Claims appended hereto and their equivalents.
