A flow splitter may include an inlet, at least two outlets, and an internal vane comprising a first end corresponding to the inlet and a second end corresponding to the at least two outlets, wherein the internal vane is configured to turn, between the first end and the second end, an internal flowing fluid from 0 degrees to a degree between about 60 degrees and 150 degrees. Methods of dividing fluid flow are also provided.

A resonator includes: an inner pipe having first openings penetrated into an outer peripheral surface thereof from an inner peripheral surface thereof and second openings spaced apart from the first opening; a first cover adapted to allow a first resonant space to be formed between the outer peripheral surface of the inner pipe and the inner peripheral surface thereof, the first resonant space communicating with the internal space of the inner pipe through the first openings; and a second cover adapted to allow a second resonant space to be formed between the outer peripheral surface of the inner pipe and the inner peripheral surface thereof, the second resonant space communicating with the internal space of the inner pipe through the second openings.

A straddle-type vehicle (100) includes a frame (20) and an engine (10) mounted on the frame (20). The engine (10) includes a cylinder head (11) positioned toward the rear end of the frame, and located below a saddle seat. The cylinder head faces toward the rear end of the frame, which allows the heated cylinder head of the engine and the exhaust pipe connected to the cylinder head to avoid the position where the user's legs contact the vehicle while riding, so the effect of heat emitted from the cylinder head on the rider's experience is reduced.

The invention relates to a an air supply arrangement (100) for supplying air from the atmosphere towards an internal combustion engine in a vehicle, the air supply arrangement comprising an air intake (101) for intake of air from the atmosphere, an air outlet (102) for outlet of air towards the internal combustion engine, and an air duct (103) for leading air from the air intake (101) in a downstream direction to the air outlet (102). A separator (200) is arranged in the air duct (103) so as to divide the air duct (103) into an upstream portion (104) and a downstream portion (105) for filtering of atmospheric air from debris by passage of said atmospheric air through the separator (200). The air supply arrangement (100) further comprises a compressed air delivery arrangement (300) being arranged to supply compressed air towards the separator (200) for cleaning the separator (200) from assembled debris.

A method for manufacturing a waterproof felt duct may include (a) laminating a waterproof film on one side of a first nonwoven fabric and laminating a second nonwoven fabric on the waterproof film laminated on the first nonwoven fabric to form a laminated body; (b) forming a waterproof felt base material by thermally adhering the laminated body; (c) cutting the waterproof felt base material into a desired shape; (d) molding a duct while surrounding the waterproof felt base material cut into the desired shape around the external surface of a molding jig having a worm gear shape; (e) heat-treating the molded duct; (f) cooling the heat-treated duct; and (g) ejecting the cooled duct from the molding jig.

Methods and systems are provided for an air intake system. In one example, an air intake system is provided. The air intake system includes a first air inlet duct providing intake air to an engine intake conduit, the first air inlet duct including an opening positioned external to an engine compartment. The air intake system also includes a second air inlet duct positioned upstream of the engine intake conduit and external to the engine compartment, the second air inlet duct including a funnel shaped to flow air to only a portion of an air filter.

A physical quantity measuring device is configured to measure a physical quantity of a fluid. The physical quantity measuring device includes: at least two humidity detection parts configured to output a humidity signal corresponding to a humidity of the fluid; and an abnormality determination part configured to determine that an abnormality has occurred in the humidity detection parts in response to that a difference between the humidity signals obtained from the two humidity detection parts exceeds an abnormality determination threshold.

A body structure includes a generally trough-shaped first structural member having a floor, two opposed side walls having respective top edges, and an open top along a length of the first structural member defining a generally U-shaped cross-section. The first structural member has a first portion with a first flow direction therethrough and a second portion with a second flow direction therethrough different from the first flow direction, the first portion having opposed first and second ends with a first opening in the first end, the second portion having opposed third and fourth ends with a second opening in the fourth end, wherein the second and third ends are in fluid communication with each other. The first portion has a first average depth and the second portion has a deepened portion having a second average depth larger than the first average depth.

An air intake device with a variable-length intake duct, comprising: a base duct component with a base duct, configured for the passage of intake air through the base duct component, an extension duct component with an extension duct, configured for the passage of intake air through the extension duct component, a guidance arrangement which guides the extension duct component and the base duct component to relative movement between a first operating position and a second operating position, wherein in the first operating position the base duct and the extension duct form, in mutually prolonging abutment, a continuous duct section, and wherein in the second operating position the extension duct is arranged at a distance from the base duct, and a first centering arrangement which when the duct components approach the first operating position is configured to decrease a radial distance in relation to a virtual base duct path conceived as passing centrally through the base duct between an end section of the base duct facing towards the extension duct component and an end section of the extension duct facing towards the base duct component, wherein the first centering arrangement is configured as separate from the base duct and from the extension duct.

An assurance cap for use with a fluid connector assembly for coupling a tubular member including an endform to a connector body, the endform defining a radially disposed shoulder, a retainer clip carried on the connector body and extending at least partially into a first bore in the connector body to engage the shoulder to lock the tubular member in the connector body when the first insertion end is fully inserted into the first bore, the assurance cap including a body including a first end and a second bore for disposing the body over the tubular member, and a plurality of primary latch fingers arranged on the body, each of the plurality of primary latch fingers including an end projection configured for latching in an exterior groove of the connector body to latch the body on the connector body when the tubular member is fully inserted into the connector body.
