OIL AIR SEPARATOR SYSTEM AND METHOD

Abstract

The oil air separator system is designed to stop oil contaminated air from entering the intake manifold. All engines have a vacuum hose from the valve cover or valley pan connected to the intake manifold. The device serves to evacuate blow by from the engine. The contaminated air (with oil vapors) is effectively removed. This prevents oil deposits from being realized inside the intake manifold and on the spark plugs. By removing the dirty air, the engine can breathe clean air. The container can hold the oil and water while the filter inside keeps the air clean reducing pollution.

DETAILED DESCRIPTION

[0016] As discussed above, embodiments of the present disclosure relate to a filtering means for use with internal combustion engines and more particularly to an oil air separator system and method as used to improve the longevity of engine life and to minimize air pollution.

[0017] Generally, the present invention serves to promote engine efficiency and reduce pollution by collecting contaminants from the crankcase and prevents them from entering the intake manifold. Referring now more specifically to the drawings by numerals of reference, there is shown in FIGS. 1-5, various views of an oil air separator system 100. FIG. 1 shows an oil air separator system 100 during an in-use condition 150, according to an embodiment of the present disclosure. Here, the oil air separator system 100 may be beneficial for use by a user to clean contaminants from the crankcase of the internal combustion engine 102 and prevent them from entering the intake manifold 104 (in-use condition 150).

[0018] FIGS. 2-5 show respectively, a side view of the oil air separator system 100 (as connected to the internal combustion engine 102 ready for completion of install); a perspective view of the oil air separator system 100; a perspective view of the top shell 108 and the bottom shell 106 (as uncoupled) of the oil air separator system 100 and a top view of the bottom shell 106 and the ingress tube 160 of the oil air separator system 100 of FIG. 1, all according to an embodiment of the present disclosure.

[0019] As illustrated, starting with FIG. 1, the oil air separator system 100 may include a canister 110 having a body 112 forming a housing 114 with an inner volume 116 and an outer surface 118; an ingress port 120; an egress port 130; a removable filter 140; and an ingress tube 160. The housing 114 is defined by the outer surface 118 effectively enclosing the inner volume 116; the ingress port 120 permitting an input-air-solution (contaminated air from the crankcase) to enter the ingress tube 160 from the internal combustion engine 102 to pass through a bottom portion 117 before being filtered through the removable filter 140 and passing through the inner volume 116 to the egress port 130 and out to the intake manifold 104 such that the contaminants from the input-air-solution are left in the bottom portion 117. In this way the clean-filtered-air is able to pass into the intake manifold 104 to increase efficiency in operation and longevity of the internal combustion engine 102.

[0020] The ingress tube 160 is located in bottom portion 117 during use such that the contaminants flowing through the ingress tube 160 traveling from the crankcase come to rest in the bottom portion 117 are stopped and are contained within the bottom portion 117 for later disposal and not allowed to pass further into the intake manifold 104. This filtration reduces maintenance on the remainder of the system (spark plugs, etc.) of the internal combustion engine 102. The canister 110 comprises a top shell 108 and a bottom shell 106 (comprising bottom portion 117). The top shell 108 and the bottom shell 106 are removably couplable to and from each other via threads (threading as shown in FIGS. 4-5) and an O-ring for sealing; however alternate embodiments may comprise a one-piece construction or other means for coupling).

[0021] Referring now to the bottom shell 106; the bottom shell 106 comprises a filter shelf 124 such that when the removable filter 140, when placed, is located above the surface of the bottom portion 117 such that oil and other contaminates do not come into contact with the removable filter 140. The ingress port 120 and the egress port 130 pass into the inner volume 116 of the body 112 from the top shell 108; wherein the ingress port 120 and the egress port 130 in preferred embodiments each comprise a respective fitting (90-degree fitting or other may be used as per vehicular specific application for ease of fitting within the engine bay space provided). Each of the respective fittings preferably comprises a barbed-end (FIG. 3) such that the hoses attached thereto are held in stasis during use. Each of the respective fittings are able to connect to a length of hose as shown (FIGS. 1-2), one hose from the crankcase of the internal combustion engine 102 and another connecting to the intake manifold 104.

[0022] The bottom shell 106 of the canister 110 of the oil air separator system 100 comprises the bottom portion 117. The top shell 108 and the bottom shell 106 are removably couplable to and from each other, as shown in FIGS. 4-5. The ingress tube 160 (during use) passes through the removable filter 140 and the ingress tube 160 passes through the filter shelf 124. The removable filter 140 comprises an aperture 142 allowing the ingress tube 160 to pass through the removable filter 140; wherein the removable filter 140 comprises a mesh 144 suitable to collect contaminates. The removable filter 140 is able to be replaced or cleaned. The ingress tube 160 comprises suitable material that resists degradation when contacting contaminates (such as oil) such that a sufficient longevity of use for the oil air separator system 100 is achieved. The bottom shell 106 and the top shell 108 may have an O-ring placed between them to promote sealing of the canister 110.

[0023] Removable filter 140 comprises mesh 144 comprising a particulate air filter composed of fibrous or porous materials which removes solid particulates such as dust, pollen, and the like from the air. Removable filter 140 may contain an absorbent or catalyst such as charcoal (carbon) to remove odors and gaseous pollutants in alternate embodiments. In certain embodiments foam, pleated paper, cotton filters, or spun fiberglass filter elements may be used. Those with ordinary skill in the art will now appreciate that upon reading this specification and by their understanding the art of filters as described herein, methods of filtration will be understood by those knowledgeable in such art.

[0024] According to one embodiment, the oil air separator system 100 may be arranged as a kit 105. In particular, the oil air separator system 100 may further include a set of instructions 107. The instructions 107 may detail functional relationships in relation to the structure of the oil air separator system 100 such that the oil air separator system 100 can be installed, used, maintained, or the like, in a preferred manner.

[0025] A method of use includes steps of: installing the device disclosed herein (retro-fit or OEM), using the device to remove contaminates before the air reaches the intake manifold, changing the filter (or cleaning as needed), and servicing as required. The use of step of should not be interpreted as step for, in the claims herein and is not intended to invoke the provisions of 35 U.S.C. 112(f). It should also be noted that, under appropriate circumstances, considering such issues as design preference, user preferences, marketing preferences, cost, structural requirements, available materials, technological advances, etc., other methods for use of the oil air separator system 100, are taught herein.

[0026] The embodiments of the invention described herein are exemplary and numerous modifications, variations and rearrangements can be readily envisioned to achieve substantially equivalent results, all of which are intended to be embraced within the spirit and scope of the invention. Further, the purpose of the foregoing abstract is to enable the U.S. Patent and Trademark Office and the public generally, and especially the scientist, engineers and practitioners in the art who are not familiar with patent or legal terms or phraseology, to determine quickly from a cursory inspection the nature and essence of the technical disclosure of the application.
