Methods and systems are provided for a convolute-swirl integrated duct (CSID). In one example the CSID may be configured to comply with engine roll and induce swirl in an intake air flow. Engine roll is absorbed as a result of a positioning of the CSID along an intake passage upstream of a compressor inlet and pre-whirl is introduced to intake air prior to delivery of the intake air to a compressor.

A resin composition for intake hoses is provided. The resin composition includes a predetermined amount of polyester elastomer incorporated into a polyamide resin and a polypropylene resin and further includes an antioxidant, a heat stabilizer, a lubricant and a master batch if necessary, thereby exhibiting excellent durability, heat resistance, elongation, mechanical rigidity, pressure resistance and cold resistance, and reducing weight and production costs.

A car intercooler pipe includes an inlet of the intercooler pipe positioned at an upper side of the car intercooler pipe, an upper corrugated portion having upper corrugated bodies protruding in a rib shape from a surface of a pipe body extending in a direction toward the inlet, an outlet of the intercooler pipe positioned at a lower side of the car intercooler pipe, a lower corrugated portion, and an intermediate portion bent downward from the upper corrugated portion and having the pipe body connected to the lower corrugated portion, wherein a thickness of the pipe body of the intermediate portion is greater than a thickness of the upper corrugated body of the upper corrugated portion and a thickness of the lower corrugated body of the lower corrugated portion, and wherein disconnection portions having corrugations with different heights are formed in the upper corrugated body and the lower corrugated body.

An air cleaner of a vehicle for filtering particulate matter from air supplied through an intake includes a case with an outlet. The case surrounds the air cleaner, which further includes two connecting tubes each having a first end attached to the throttle body of the vehicle and a second end disposed in the outlet in the case of the air cleaner. A funnel is inserted into the second end of each of the connecting tubes. Clean air from the air cleaner is proved to the engine through the connecting tubes.

An air cleaner of a vehicle for filtering particulate matter from air supplied through an intake includes a case with an outlet. The case surrounds the air cleaner, which further includes two connecting tubes each having a first end disposed through the outlet and a second end located in the case. A funnel is clamped to the second end of each of the connecting tubes. A bracket is attached to each of the funnels for rigidly mounting the funnels inside the case of the air cleaner. The first end of each of the connecting tubes is further connected to the throttle body of the vehicle to provide clean air from the air cleaner to the engine.

The disclosure relates to an air filter assembly for cleaning an air stream for a commercial vehicle, including a pre-filter communicating with an air intake and a first fine filter which is provided downstream of the pre-filter in the direction of the air stream and, together with the pre-filter, is associated with an air filter part which extends vertically in a predetermined installation position. A redundant second fine filter, which is associated with an air filter part which extends horizontally in the predetermined installation position, follows the first fine filter in the direction of the air stream, the horizontally extending air filter part being a component of a syphon-like conduit region which rises in a curved manner in the direction of an air outlet, starting from the redundant second fine filter.

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.

An intake apparatus includes: an air cleaner unit purifying air sucked from a suction port and discharge the air from a discharge port; a junction pipe section having a plurality of inlet ports while having a single outlet port, each of the inlet ports being connected to the discharge port of the air cleaner unit; a tapered pipe section connected to the outlet port of the junction pipe section and having an inner diameter gradually decreased toward a downstream; a straight pipe section connected to a downstream side of the tapered pipe section and having a constant inner diameter; and an air meter provided in the straight pipe section.

The layered product includes at least one type of layer selected from the layers (1) and (2), and at least one type of layer selected from the layers (3) and (4), in which at least one layer of the at least one type of layer selected from the layers (1) and (2) is directly in contact with or adjacent via an adhesive layer to at least one layer of the at least one type of layer selected from the layers (3) and (4): layer (1): a layer prepared using an ethylene/-olefin/non-conjugated polyene copolymer; layer (2): a layer prepared using an ethylene/carboxylic acid copolymer; layer (3): a layer prepared using an acrylic-type rubber; and layer (4): a layer prepared using a halogen-containing polymer.
