An air cleaner hose is provided. The air cleaner hose includes a bellows part and a low-rigidity part. The low-rigidity part is in a region between the bellows part and one end of the air cleaner hose. The low-rigidity part is included in a part of the air cleaner hose in a circumferential direction, wherein the low-rigidity part is configured to have a buckling deformation such that a buckling load of the low-rigidity part with respect to a compressive load in an axial direction of the air cleaner hose is smaller than a buckling load of a region other than the low-rigidity part with respect to the compressive load.

An apparatus may comprise a base member being defined by a rectangular aperture configured to receive and engage an automobile intake box, the base member being further defined by a perimeter surrounding the rectangular aperture and having at least one fastener or aperture configured to receive a fastener dimensioned to avoid disturbing the automobile intake box; a gooseneck member fixedly attached to the base member, the gooseneck member having a first end opening and a second end opening, the gooseneck member having an interior cavity configured to direct air into the automobile intake box from the second end opening to the first end opening through the interior cavity; and an interchangeable bell housing removably secured to the second end opening of the gooseneck member, the interchangeable bell housing having a frustoconical shaped cross section on at least one plane.

An apparatus for cooling intake air temperature of a vehicle may include a vortex tube receiving high pressure air discharged from an intercooler of a vehicle and then separating the high pressure air using centrifugation into high temperature air and low temperature air; a first bypass line connecting the vortex tube with a compressor, allowing the low temperature air to move therethrough, and selectively opened/closed by a first check valve; a second bypass line connecting the vortex tube with an exhaust line of the vehicle and allowing the high temperature air to move therethrough as a second check valve is opened/closed; and a controller controlling to open or close the first and second check valves.

An anti-crush ring is disclosed for insertion into hollow articles for localized reinforcement. The anti-crush ring comprises a generally annular or ring-like wall structure and at least one expansion hoop inwardly extending from the wall structure. Upon insertion of the anti-crush ring into the hollow article, the at least one expansion hoop is compressed and deformed to urge the wall structure of the anti-crush ring against an inner surface of the hollow article. Also provided is a method of reinforcing the inlet or outlet of a hollow article.

In an intake device for an internal combustion engine, a difference in the air-fuel ratio between the cylinders is reduced without increasing the lengths of the branch passages. An intake device (23) for an internal combustion engine (1) having at least three cylinders (3) includes: an intake chamber (30) configured to be connected with an air inlet (16); and multiple branch passages (31) connected at upstream ends (41) thereof to the intake chamber and connected at downstream ends thereof to intake ports (6) communicating with the cylinders, respectively, wherein the upstream ends of the branch passages are arranged in a direction of rotation about a predetermined center line X in a same order as an order of ignition of the cylinders.

An air intake system is disclosed. The air intake system may have an air box. The air box may be configured to receive air from an ambient. The air intake system may also have a filter assembly disposed within the air box. The filter assembly may be configured to clean the air. In addition, the air intake system may have a duct. The duct may have a first duct end configured to receive the air exiting the filter assembly. The duct may also have a second duct end configured to deliver the air to the engine. The second duct end may be located at a gravitationally higher position than the first duct end.

In an air intake device for motorcycle, an air cleaner having a front end formed with a main intake port is disposed between a pair of left and right main frame pieces forming a main frame. An introducing passage is formed within the main frame for capturing an incoming wind. An intake air introducing port of the introducing passage is provided at a location rearwardly of the main intake port in the main frame piece. An intake air discharge port is defined in an intermediate portion of a front portion of the main frame with respect to a motorcycle widthwise direction so as to open rearwardly and to be fluid connected with the main intake port. A sub intake port is provided in communication with the main intake port so as to introduce an intake air into the main intake port.

An apparatus for cooling intake air temperature of a vehicle may include a vortex tube receiving high pressure air discharged from an intercooler of a vehicle and then separating the high pressure air using centrifugation into high temperature air and low temperature air; a first bypass line connecting the vortex tube with a compressor, allowing the low temperature air to move therethrough, and selectively opened/closed by a first check valve; a second bypass line connecting the vortex tube with an exhaust line of the vehicle and allowing the high temperature air to move therethrough as a second check valve is opened/closed; and a controller controlling to open or close the first and second check valves.

An apparatus may comprise a base member defined by a rectangular aperture configured to receive and engage an automobile intake airbox. The base member may be further defined by a perimeter surrounding the rectangular aperture and having at least one fastener or aperture configured to receive a fastener dimensioned to avoid disturbing the automobile intake airbox. A gooseneck member may be fixedly attached to the base member. The gooseneck member may have a first end opening and a second end opening, with an interior cavity configured to direct air into the automobile intake airbox from the second end opening to the first end opening. An interchangeable bell housing may be removably secured to the second end opening of the gooseneck member. The interchangeable bell housing may have a frustoconical shaped cross section on at least one plane.

In one aspect, an apparatus may include a base member being defined by an aperture configured to receive and engage an automobile intake box, the base member being further defined by a perimeter surrounding the aperture and having at least one fastener or aperture configured to receive a fastener dimensioned to avoid disturbing the automobile intake box; a base member fixedly attached to the base member, the base member having a first end opening and a second end opening, the base member having an interior cavity configured to direct air into the automobile intake box from the second end opening to the first end opening through the interior cavity; and an interchangeable bell housing removably secured to the second end opening of the base member, the interchangeable flare housing having a plurality of types of shaped cross sections on at least one plane.
