BACKGROUND OF THE INVENTION

Field of the Invention

The present invention relates to an air cleaner device and an engine having the same, and more particularly, to an air cleaner device which improves structural rigidity and may be provided for common use regardless of the type of engine, and an engine having the same.

Description of Related Art

In general, an air cleaner for a vehicle is configured to remove dust and foreign substances contained in outside air introduced into an engine.

The air cleaner has a filter or an element provided in a casing, such that outside air is filtered while passing through the filter or the element.

Here, the air cleaner is classified into a dry air cleaner and a wet air cleaner based on the type of the embedded element.

The dry air cleaner uses paper or a fiber material as the element, and the wet air cleaner uses oil as the element.

The dry air cleaner is used in most cases, but the wet air cleaner is used in a case in which it is difficult to change the element due to an installation location or a maintenance situation.

Therefore, the dry air cleaner is mostly used for an air cleaner for a vehicle of which the element is easily changed.

The air cleaner is associated with the engine and disposed in an engine compartment, and in some vehicles, a space is narrow due to arrangement design of the engine compartment or there may be no appropriate arrangement space unless the shape of the air cleaner is changed.

The air cleaner for a vehicle in the related art typically has a structure in which an upper casing is fixed to a lower casing by bolts and clamps. Thus, the upper casing needs to be completely separated from the lower casing to change a filter, and as a result, a space is further required to separate the upper casing.

Therefore, the air cleaner for a vehicle in the related art is configured as an obstruction that hinders free and effective arrangement design of the engine compartment, and the air cleaner for a vehicle in the related art also occupies a larger space.

Referring toFIG. 1andFIG. 2, an engine encapsulation10is provided in an engine compartment1of a vehicle to which an air cleaner device for a vehicle according to an exemplary embodiment of the present invention is applied.

The engine encapsulation10of the engine compartment1is mounted on a vehicle body20to surround an engine ENG.

Here, the engine encapsulation10of the engine compartment1is a shield apparatus for the engine ENG and inhibits heat generated in the engine ENG from radiating to the outside, such that a temperature of the engine ENG is maintained and fuel consumption is minimized when the engine ENG is initially started.

First, the vehicle body20includes a cowl21, fender apron upper members22, fender apron reinforcing members23, front end portion modules24, front side members25, and shock absorber housings26.

The cowl21is a panel connected at a front side of a front glass of the vehicle.

In addition, the cowl21may extend from a dash board or may be mounted on the dash board.

The fender apron upper member22is an upper member of a fender apron.

That is, the fender apron upper member22is provided at an upper side of the fender apron which is disposed inside a fender, which is a mudguard, and the fender apron is configured as a partition between a wheel and the engine compartment1.

The fender apron reinforcing member23connects the fender apron to other members of the vehicle body20to reinforce rigidity of the fender apron.

The fender apron reinforcing member23connects the fender apron upper member21to the front end portion module24.

Furthermore, the front side member25is provided below a front floor or and the dash board in a longitudinal direction, which is a longitudinal direction of the vehicle body, and the front side member25is a beam that defines a framework of a front body.

The shock absorber housing26is a portion in which a shock absorber is mounted, and the shock absorber housing26is disposed between the fender apron upper member22and the front side member25.

The front end portion module24is a member made by integrating several components at a front side of the vehicle body20into a single module.

That is, the front end portion module24is disposed at a foremost side of the front body.

Because the members of the vehicle body20, which form the front body, are obvious to those skilled in the art, a further detailed description thereof will be omitted.

Meanwhile, the engine encapsulation10includes a lateral shield plate11, an upper shield plate13, and a lower shield plate15.

The lateral shield plate11shields a lateral side and a rear side of the engine compartment1, and the lateral shield plate11is connected to the vehicle body20.

In the present description, the upward, downward, forward, and rearward directions are based on the upward, downward, forward, and rearward directions of the vehicle.

The upper shield plate13is disposed to cover the lateral shield plate11.

That is, the upper shield plate13shields an upper side of the engine compartment1.

In addition, one end portion of the upper shield plate13is mounted on the front end portion module24, and one end portion of the lateral shield plate11is mounted on the front side member25.

Furthermore, the lower shield plate15is provided to shield a lower side of the engine compartment1.

In addition, the lower shield plate15is mounted on an under guard3.

In addition, the lower shield plate15may be formed to have a surface disposed on the same plane as the under guard3.

Here, the under guard3is a panel for protecting driving devices disposed at lower and bottom sides of the engine ENG.

One front end portion of the under guard3is connected to the front end portion module24and extending rearward while passing over front wheels of the vehicle.

Furthermore, the lower shield plate15may extend in a longitudinal direction of the under guard3.

Therefore, the lower shield plate15may cover not only the lower side of the engine ENG, but also various devices disposed at the lower side of the vehicle.

The lateral shield plate11, the upper shield plate13, and the lower shield plate15may be integrally formed or may be independently formed and then assembled.

Meanwhile, an air cleaner device30for a vehicle according to the exemplary embodiment of the present invention is connected to the engine encapsulation10.

That is, the air cleaner device30may be mounted to support the upper shield plate13of the engine encapsulation10.

The air cleaner device30is provided to receive air from the outside of the engine encapsulation10.

Meanwhile, the engine compartment1is a space in which the engine ENG is disposed.

In addition, an upper side of the engine compartment1is closed by a hood5which is called a bonnet, a lateral side of the engine compartment1is closed by the vehicle body20, and a lower side of the engine compartment1is closed by the under guard3.

Because the engine compartment1, which is formed to be surrounded by the under guard3, the hood5, and the vehicle body20, is obvious to those skilled in the art, a further detailed description thereof will be omitted.

Meanwhile, the engine compartment1is divided by the engine encapsulation10.

That is, since the engine encapsulation10is disposed to surround the engine ENG in the engine compartment1, the engine compartment1is divided into an internal side and an external side of the engine encapsulation10.

In addition, since the engine encapsulation10inhibits heat generated in the engine ENG from radiating to the outside, the internal side of the engine encapsulation10is a high-temperature region (hot area) H in which an air temperature is relatively high, and the external side of the engine encapsulation10is a low-temperature region (cold area) C in which an air temperature is relatively low.

FIG. 3is an exploded perspective view of the air cleaner device for a vehicle according to the exemplary embodiment of the present invention,FIG. 4is a partially enlarged perspective projection view of the air cleaner device for a vehicle according to the exemplary embodiment of the present invention, andFIG. 5is a cross-sectional view taken along line V-V inFIG. 4.

Referring toFIG. 3,FIG. 4, andFIG. 5, the air cleaner device30for a vehicle according to the exemplary embodiment of the present invention includes an air housing31, an air duct33, a filter casing35, and an air filter37.

The air housing31may be formed in, but not limited to, a pipe shape, and air housings having various shapes may be applied in accordance with a shape of the engine compartment.

In addition, hose outlets40are formed in the air housing31.

In the instant case, the hose outlet40may be connected to an air intake hose.

The air intake hose is formed to extend to an intake passageway of the engine ENG so that outside air introduced into an internal space of the air housing31is supplied to the engine ENG.

That is, the air intake hose is configured as a passageway through which air filtered by the air filter37is sent to a throttle body of the engine ENG, and the air intake hose also is configured to absorb vibration generated by the engine ENG.

The number of hose outlets40connected to the air intake hose and the position of the hose outlets40may be changed in accordance with the type of engine ENG.

That is, the hose outlet40may be changed in number and position in accordance with the number of intake passageways formed in the engine ENG and the installation position of the intake passageways, and as a result, the air cleaner device may be applied to various types of vehicles.

In addition, as shown inFIG. 3, the air housing31may include four rounded edge portions, but it is not limited thereto.

The air housing31is disposed along an edge portion of the engine compartment1and may support the upper shield plate13.

That is, the air housing31is disposed at the lower side of the upper shield plate13and supports the upper shield plate13.

In addition, the air cleaner device30for a vehicle according to the exemplary embodiment of the present invention is connected to the lateral shield plate11, improving structural rigidity of the lateral side of the engine compartment.

In addition, an installation port41for mounting the air filter37is formed at one side of the air housing31to face the filter casing35.

The air housing31includes a cover43mounted on the installation port41.

In the instant case, the cover43may include a horizontal surface43a, and a vertical surface43bbent in the longitudinal direction thereof, and the cover43is mounted on the installation port41.

For example, the cover43may be mounted on the installation port41in an interference fit manner or by fastening bolts.

A plurality of support protrusions45protrudes on the cover43at both sides of an internal surface of the cover43which faces the air filter37so that the air filter37is press-fitted into the filter casing35.

Furthermore, the air duct33protrudes from the air housing31and introduces outside air.

The air duct33is formed integrally with the air housing31in a state in which the air duct33is opened toward the front side of the engine compartment1.

The air duct33may be elongated in a vehicle's width direction to increase an introduction area through which outside air is introduced.

Furthermore, the filter casing35is formed in the air housing31to mount the air duct33.

The filter casing35includes a filter seating portion35athat supports the air filter37.

In the instant case, the filter seating portion35ais formed to be inclined downward from the front side to the rear side of the air housing31so that the air filter37is mounted in an inclined state.

Since the air filter37is mounted in an inclined state, a contact area between the air filter37and the introduced air is relatively increased, such that filter efficiency may be improved and a local increase in air pressure may be prevented.

In addition, the filter casing35includes support surfaces35bof which both sides directed toward the internal passageway of the air housing31have triangular cross sections, and the support surfaces35bserve as partition walls with respect to a portion of the internal passageway.

In other words, the filter casing35includes the support surfaces35bformed at both sides of the filter seating portion35a, and prevents the outside air introduced from the air duct33from being introduced into the internal passageway of the air housing31without passing through the air filter37.

In addition, the air filter37is press-fitted into the filter seating portion35aby the support protrusions45of the cover43, and as a result, the air filter37is prevented from being separated.

The air cleaner device30for a vehicle according to the exemplary embodiment of the present invention may be applied to the engine compartment1provided with the engine encapsulation10including the lateral shield plate11, the upper shield plate13, and the lower shield plate15, and the air cleaner device30is disposed at the lower side of the upper shield plate13to support the upper shield plate13, improving structural rigidity.

In addition, the air cleaner device30for a vehicle according to the exemplary embodiment of the present invention is connected to the lateral shield plate11, improving structural rigidity of the lateral side of the engine compartment.

In addition, the air cleaner device30for a vehicle according to the exemplary embodiment of the present invention may be applied by changing only the hose outlet40of the air housing31in accordance with the type of engine ENG, and as a result, production costs may be reduced and efficient specification management is enabled.

The air cleaner device30for a vehicle according to the exemplary embodiment of the present invention may be provided even in a vehicle to which no engine encapsulation10is applied, and the air cleaner device30may be applied to various engines or various engine compartment shapes, and as a result, the components may be used in common.
