[0026] In general, the present disclosure describes an apparatus and a method for an aircharger air intake system configured to conduct filtered air to an air intake of an engine. The aircharger air intake system includes an air filter comprising a filter medium configured to pass an airstream and entrap particulates flowing within the airstream. An air box comprising one or more sidewalls and a mount wall is configured to support the air filter within an engine bay. The air box is configured to be mounted, or fastened, to an interior of the engine bay. An intake tube is coupled with the air filter and configured to conduct the airstream to the air intake. The intake tube generally comprises an arrangement of one or more bends and one or more straight portions configured to communicate the airstream from the air filter to the air intake of the engine. In some embodiments, the intake tube may be configured to be coupled with an air temperature sensor or a mass air sensor of the engine. An adapter is configured to couple the intake tube with the air intake of the engine.
[0027] Although embodiments of the present disclosure may be described and illustrated herein in terms of a cylindrical air filter, it should be understood that embodiments of the present disclosure are not limited to the exact shape illustrated, but rather may include a wide variety of generally cylindrical shapes, generally circular, oval, round, curved, conical, or other closed perimeter shape, that provide a relatively large surface area in a given volume of the filter. Moreover, embodiments as described herein are not limited to use as internal combustion engine filters, but may have applicability in other filtration systems in which a large volume of air needs to be treated.
[0028]
[0029] The air filter 108 comprises a filter medium that provides an area to pass an airstream and entrap particulates and other contaminates flowing with the airstream. The filter medium may be comprised of paper, foam, cotton, spun fiberglass, or other known filter materials, woven or non-woven material, synthetic or natural, or any combination thereof. The filter medium may be pleated, or otherwise shaped, or contoured so as to increase a surface area for passing the airstream to be cleaned. The length of the filter medium in the circumferential direction may be longer than the circular circumference of the air filter 108 generally, such that the surface area of the filter medium is greater than the profile surface area of the air filter 108.
[0030] In some embodiments, the filter medium comprises 4 to 6 layers of cotton gauze sandwiched between two epoxy-coated aluminum wire screens. The cotton may be advantageously treated with a suitably formulated filter oil composition that causes tackiness throughout microscopic strands comprising the filter medium. The nature of the cotton allows high volumes of airflow, and when combined with the tackiness of the filter oil composition creates a powerful filtering medium which ensures a high degree of air filtration. Further details about components comprising the air filter 108, as well as details about the filter oil composition, are disclosed in U.S. patent application Ser. No. 14/181,678, entitled “Air Box With Integrated Filter Media,” filed on Feb. 16, 2014, and U.S. patent application Ser. No. 14/701,163, entitled “Filter Oil Formulation,” filed on Apr. 30, 2015, the entirety of each of which is incorporated herein by reference.
[0031] The air box 104 generally is of an open variety, rather than being an enclosed air box as is conventionally utilized with many vehicles. The sidewalls 112 and the floor 114 serve to protect the air filter 108 from road debris, as well as to isolate the air filter 108 from hoses and other components that may be present within an engine bay of the vehicle. It will be recognized by those skilled in the art that the open air box 104 improves airflow to the air filter 108, and thus decreases air resistance to the air intake of the engine, thereby improving engine performance beyond that otherwise possible with an enclosed air box. The air box 104 generally is configured to be mounted, or fastened, onto the engine. As shown in
[0032] The mount wall 116 generally is configured to support the air filter 108 and provide an interface between the air filter 108 and the air intake of the engine. An opening 120 in the mount wall 116 is configured to receive an intake tube 124 that is configured to couple the air filter 108 with the air intake of the engine. In the embodiment illustrated in

[0034] Moreover, in some embodiments, the intake tube 124 may comprise one or more grommets that are removable from openings within the wall of the intake tube and are configured to receive any of various hoses and sensors that may extend from the engine. In the embodiment of
[0035] As will be appreciated by those skilled in the art, the configuration of the adapter 128 and the clamps 132 depend upon the particular vehicle for which the aircharger system 100 is to be used. For example,
[0036] As will be appreciated, the intake tube 172 is similar to the intake tube 124, with the exception that two of the flanges 144 are disposed on the intake tube 172 in locations different than on the intake tube 124. In the embodiment illustrated in
[0037]
[0038]
[0039] As discussed with respect to the air box 104, illustrated in
[0040] It will be recognized that, similarly to intake tube 172, the intake tube 228 is comprised of an arrangement of one or more bends 136 and straight portions 140 suitable to communicate an airstream from the air filter 168 to the air intake of the engine. The intake tube 228 further comprises an adapter assembly 188 configured to couple a mass air sensor assembly of the engine with the intake tube, and includes a flange 144 configured to receive a crankcase ventilation hose 148 extending from the engine. An adapter 252 and a pair of clamps 132 are configured to secure the intake tube 228 to a throttle body 256 of the engine. As further illustrated in
[0041]
[0042] As with the air boxes discussed above, the air box 280 preferably is comprised of a rigid material that is sufficiently durable and temperature resistant to retain its configuration during installation and operation when coupled with the air intake of the engine. A pliable strip 296 is disposed along top edges of the sidewalls 112 and the mount wall 116 so as to hide any sharp edges thereon. Similarly, pliable strips 300 are disposed along bottom edges of the sidewalls to hide sharp edges. As will be recognized by those skilled in the art, the pliable strips 296 and 300 serve to reduce the incidence of injury during installation and maintenance of the aircharger system 268.
[0043] With the adapter 284 mounted to the mount wall 116, as described, an airtight seal is established between the adapter 284 and the intake tube 272 by way of an adapter 304 and suitably sized clamps 127. Similarly, the intake tube 272 is coupled to the air intake of the engine by way of an adapter 308 and clamps 132. As will be appreciated, the intake tube 272 comprises an arrangement of one or more bends 136 and straight portions 140 suitable to couple the air filter 276 with the air intake of the engine. Further, the intake tube 272 comprises an assembly 188, configured to receive a mass air sensor assembly of the engine, and a flange 144 to receive a crankcase ventilation hose 148.

[0046] The mount wall 116 generally is configured to support the air filter 276 and provide an interface between the air filter 276 and the intake of the engine. An opening 120 in the mount wall 116 is configured to receive an adapter 284 that may be fastened to the mount wall 116 by way of fasteners 348. A suitably sized clamp 126 may be used to secure the adapter 284 within a flange 352 of the air filter 276. Further, an adapter 356 may be used to couple the intake tube 324 with the adapter 284. A pair of clamps 127 may be used to ensure that the adapter 356 forms an airtight seal between the adapter 284 and the intake tube 324.
[0047] As shown in
[0048] The intake tube 324 may comprise one or more flanges or other fittings configured to receive various ventilation hoses and sensors that may extend from the engine. In the illustrated embodiment of
[0049] Moreover, the aircharger system 320 may optionally include one or more wiring harnesses 368 comprising suitably sized sockets and is configured to extend an existing wiring harness of the engine to the air temperature sensor installed into the intake tube 324. It will be recognized that the existing wiring harness may be plugged into a first socket of the wiring harness 368 and then a second socket of the wiring harness 368 may be plugged into the air temperature sensor. In those embodiments wherein the air temperature sensor is absent, the grommet 364 may be installed into the opening in the intake tube so as to prevent unwanted air entering into the air intake of the engine.
[0050]
[0051] The air box 384 generally is configured to be mounted, or fastened, to the engine within an interior of an engine bay. In the embodiment shown in
[0052] As shown in
[0053] Moreover, the intake tube 376 generally comprises one or more flanges or other fittings configured to receive various ventilation hoses or sensors extending from the engine. In the illustrated embodiment of
[0054] As shown in
[0055]
[0056] An opening 120 in the mount wall 116 receives an adapter 460 that is secured to the mount wall by way of fasteners 462. The adapter 460 is further secured to an adapter 464 by way of a first clamp 127. A second clamp 127 affixes the adapter 464 to a mass air sensor 468 of the engine. A third clamp 127 secures the mass air sensor 468 to an adapter section 472, and a fourth clamp 127 secures the adapter section 472 to the intake tube 444. Similarly, a suitably sized clamp 126 secures the adapter 460 within a flange 476 of the air filter 448, such that the air filter is coupled with the intake tube 444.
[0057] As will be appreciated, the air box 452 is configured to be mounted to the engine, as discussed above. The sidewall 112 and the mount wall 116 are configured to respectively receive suitable fasteners 480 and 484 to mount the air box onto the engine. The fasteners 480 and 484 generally comprise any of suitably designed holes, brackets, molded shaped portions, protrusions, extensions, angled brackets, hardware fasteners, or other any similar device for holding the air box fixed within the engine bay. As will be recognized, the particular fasteners will vary according to the specific make and model of the vehicle with which the air box 452 is to be used.
[0058] In the embodiment illustrated in
[0059] As shown in
[0060]
[0061] It is contemplated that a user of any of the above-discussed aircharger systems may periodically clean the filter medium of the air filter rather than replacing the air filter, as is typically done with conventional air filtrations systems. It is envisioned that the air filter may be removed from any of the air boxes discussed herein and then a water hose used to flush contaminants from the filter medium, thereby leaving the air filter clean and ready for reuse. In some embodiments, wherein the filter medium comprises a filter oil composition, a solvent may be used to remove the oil from the filter medium. Once the filter medium is completely dry, a suitably formulated filter oil composition may be uniformly applied and allowed to wick into the filter medium. Various other cleaning methods will be apparent to those skilled in the art without deviating from the spirit and scope of the present disclosure.
[0062] While the invention has been described in terms of particular variations and illustrative figures, those of ordinary skill in the art will recognize that the invention is not limited to the variations or figures described. In addition, where methods and steps described above indicate certain events occurring in certain order, those of ordinary skill in the art will recognize that the ordering of certain steps may be modified and that such modifications are in accordance with the variations of the invention. Additionally, certain of the steps may be performed concurrently in a parallel process when possible, as well as performed sequentially as described above. To the extent there are variations of the invention, which are within the spirit of the disclosure or equivalent to the inventions found in the claims, it is the intent that this patent will cover those variations as well. Therefore, the present disclosure is to be understood as not limited by the specific embodiments described herein, but only by scope of the appended claims.
