The invention relates to a plug assembly (1) comprising a tube (3) and a plug connector (4), which comprises a connector body (5), wherein the connector body (5) has an annulus (18) located between a first casing section (9) and a second casing section (12) of the plug connector (4), wherein the tube (3) is inserted into the annulus (18) of the connector body (5), characterized in that a tube compensating element is arranged between the tube (3) and the second casing section (12), wherein the first casing section (9) of the connector body (5) is deformed such that an interlocking connection is established between a forming region (25) of the first casing section (9) of the connector body (5) and the tube (3), wherein the tube compensating element is clamped between the tube (3) and the second casing section (12).

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.

A combined mass airflow sensor and hydrocarbon trap is provided for absorbing evaporative hydrocarbon emissions from an air intake duct of an internal combustion engine. The combined mass airflow sensor and hydrocarbon trap comprises a duct that supports a hydrocarbon absorbing sheet in an unfolded configuration within a housing. The duct communicates an airstream from an air filter to the air intake duct during operation of the internal combustion engine. An opening in the housing receives a mass airflow sensor into the duct, such that the mass airflow sensor is disposed within the airstream. Guide vanes extending across the duct reduce air turbulence within the airstream passing by the mass airflow sensor. Ports disposed along the duct allow the evaporative hydrocarbon emissions to be drawn into the interior and arrested by the hydrocarbon absorbing sheet when the internal combustion engine is not operating.

Intake efficiency in an intake system is improved. An intake system takes air through an air inlet duct extending from an air cleaner case, and includes a vortex generator that causes the flow of the intake air inside the air inlet duct to rotate around an axis of the air inlet duct.

A snow bike intake, snow bike conversion kit, and/or air intake pod snow bike conversion kit, having: a throttle body coupling; an elbow-shaped intake duct coupled to the throttle body, a pre-filter body cage coupled at a rear thereof to the duct, and a textile cover fitting about the cage. The duct has an interior angle between 40 and 60 degrees. There are a plurality of flat (interior and exterior surface) sensor mounts disposed about and through the duct, including an octagonal ring of sensor mounts circumscribing the duct body. The cage has a flat front opposite the rear that has a larger diameter than a diameter of the rear. The duct has an aspect ratio of exterior angle length to diameter no greater than 3.5:1 and the duct and prefilter combined has an aspect ratio of exterior angle length to diameter no greater than 4.5:1.

A flow control member for a vehicle includes a body, a plurality of mounting tabs, and a panel member. The body has an outer surface and an inner surface. An air passage through the body is defined by the inner surface. A plurality of mounting tabs extends outwardly from the outer surface of the body. Each of the mounting tabs is configured to receive a fastener to connect the flow control member to an intake passage of the vehicle. A panel member is disposed in the air passage. The panel member defines a plurality of openings therethrough.

A connector arrangement (100) for connecting a first tube (102) and a second tube (104) in a detachable manner has a first connector (110) and a second connector (130), wherein both connectors (110, 130) have a closed circumference. For establishing a connection between the first and second connectors (110, 130) an internal surface of a first circumferential portion (115) of the first connector (110) is arranged on an external surface of a first circumferential portion (135) of the second connector (130) and an external surface of a second circumferential portion (118) of the first connector (110) is arranged on an internal surface of a second circumferential portion (138) of the second connector (130). An air duct having such a connector arrangement (100) and connectors for such a connector arrangement (100) is disclosed.

The air intake system includes a first piece, an intermediate piece constituting a surge tank and joined to the first piece, and a second piece including an air intake passage upstream portion in communication with the surge tank, the second piece being joined to the intermediate piece. The first piece and the intermediate piece constitute an air intake passage downstream portion in communication with the air intake passage upstream portion. The second piece further includes a flange portion that connects the air intake passage downstream portion and an air intake port of an internal combustion engine.

A snowmobile includes an engine including an engine head including a cylinder head, a supercharger, an intake manifold, throttle bodies, first joints that connect the intake manifold to the throttle bodies, second joints that connect the throttle bodies to the cylinder head, and a restrictor that connects the engine head to the first joints. The restrictor includes an engaging member that fits into grooves of the first joints, and connectors that connect the engaging member and the engine head to each other. A steering shaft is inserted between two mutually adjacent first joints which have a distance from each other greater than a distance between the other two mutually adjacent first joints.

Disclosed is an intake joint structure capable of blocking backflow of lubricating oil 18 at a connection position between an air inlet 12 of a turbocharger and a suction pipe 24. A backflow-preventive plate 25 is integrally molded to have a cylindrical portion 25a fitted over the air inlet 12 and a tapered portion 25b curved inward from an upstream end of the cylindrical portion 25a and converged downstream to provide an open end. A downstream end 24a of a suction pipe 24 is molded by soft material over a predetermined range using exchange blow molding. The cylindrical portion 25a of the backflow-preventive plate 25 is fitted over the air inlet 12 through a grommet 26 (first soft layer) and the downstream end 24a of the suction pipe 24 is fitted over the cylindrical portion 25a and is banded by a hose band 27.
