Blow molded plastic components are disclosed having integrally formed brackets, formed together with the component in the molding step. A method of blow molding is disclosed for integrally forming brackets onto a blow molded component. More specifically, the disclosures relates to a blow molded plastic component having a bracket formed integrally in the blow molding process and configured to rotate onto and lockably engage undercut features or lugs formed integrally on the outer surface of the blow molded component, all features formed during the molding process.

An air filter device is provided with a filter housing and a filter element arranged in the filter housing. A frame part is connected to the filter element and frames the filter element at least over sections thereof circumferentially. The frame part is provided with an air duct receptacle that is adapted to receive an air duct. The frame part is arranged at least partially on an exterior side of the filter housing. The filter element is fastened by the frame part on the filter housing.

An intake structure of a vehicle is provided to prevent engine oil from flowing back along a nipple. The structure includes an intake hose which is mounted between an air cleaner and a compressor of a turbo charger. A pocket part, in which the oil comprised in a blow-by gas through the nipple is collected, is formed on the inner sidewall surface of the intake hose. The intake structure prevents the oil existing in the recirculated blow-by gas from flowing into a fresh air nipple.

Embodiments for operating an engine having parallel turbochargers and two fluidically coupleable, separated intake manifolds is provided. In one example, a method includes responsive to a first condition, operating a first cylinder group of an engine, deactivating a second cylinder group of the engine, and blocking fluidic communication between a first intake manifold coupled to the first cylinder group and a second intake manifold coupled to the second cylinder group, and responsive to a second condition, activating the second cylinder group and establishing fluidic communication between the first and second intake manifolds.

An apparatus and a method are provided for an air intake assembly configured for use with Pro Stock vehicles comprising fuel injection equipped engines. The air intake assembly comprises an air inlet that includes a distal opening disposed in a forward direction at a front of the vehicle and configured to direct incident air into the air intake assembly. An air duct is joined with the air inlet by way of a first coupler configured to maintain an airtight seal between the air inlet and the air duct. A throttle body adapter is joined with the air duct by way of a second coupler configured to maintain an airtight seal therebetween. The throttle body adapter is configured to establish an airtight coupling between the air intake assembly and a throttle body of the engine, such that the incident air is directed into the throttle body.

An apparatus and a method are provided for an aircharger air intake system for filtering and conducting an airstream to an air intake of an engine. The aircharger air intake system includes an air filter comprising a filter medium configured to entrap particulates flowing within the airstream. An air box comprising one or more sidewalls and a mount wall is configured to support the air filter within an engine bay. The air box is configured to be mounted, or fastened, onto the engine. An intake tube is coupled with the air filter and configured to conduct the airstream to the air intake of the engine. The intake tube is configured to be coupled with an air temperature sensor or a mass air sensor of the engine. An adapter is configured to couple the intake tube with the air intake.

An air intake system for a vehicle has a conduit having an internal wall forming an air passage. A deflector is disposed within the air passage. A restricting structure is disposed within the air passage between the deflector and a conduit outlet. The restricting structure defines at least in part an opening substantially laterally aligned with the deflector. The restricting structure has a lateral wall disposed downstream of the deflector and extending within the air passage. The lateral wall has a front surface generally facing a conduit inlet, and a plurality of surface-increasing features provided on the front surface. Each of the surface-increasing features has a length of at least 1 mm measured from the front surface in a direction normal thereto. An air intake system having a collector connected to the deflector and positioned to collect at least some moisture from air flowing past the deflector is also described.

A vehicle air induction assembly includes an air guide, an air duct and a bracket member. The air duct is configured to supply air to an engine air filter. The air guide has an opening therein and is configured to be connected to a vehicle fascia. The air duct is configured to be connected to the air guide such that air flowing through the opening flows into the air duct. The bracket member is connected to the air guide. The bracket member has a first side wall, a second side wall and a lower wall connecting the first and second side walls. The bracket member and the air duct are disposed on opposite sides of the air guide opening. An air inlet is defined by the air guide and the bracket member.

A vehicle air induction assembly includes an air guide, an air duct and a bracket member. The air guide is configured to be connected to a vehicle fascia. The air duct is configured to be connected to the air guide. The air duct is configured to supply air to an engine air filter. The bracket member is connected to the air guide. The bracket member has a front wall facing in a forward direction of a vehicle, a rear wall facing in a rearward direction of the vehicle, and an upper wall connecting the front wall and the rear wall. A first air inlet in fluid communication with the air duct is defined by a surface of the air guide and the front, rear and upper walls of the bracket member. The first air inlet faces in a lateral direction of the vehicle.

An intake duct for an internal combustion engine includes a pipe-shaped shell. The shell includes a first molded product and a second molded product. The first molded product is formed by a plastic molded product and includes an opening extending through the first molded product in the thickness direction. The second molded product is formed by a fiber molded product produced through compression molding. The second molded product includes an air-permeable fitting projection fitted into the opening, and the second molded product is joined with an outer surface of the first molded product.
