Methods and systems are provided for a hydrocarbon (HC) trap system in an engine air induction system. In one example, a system may include a pillow-case type HC trap housed in a rectangular opening formed in a wall of an air conduit at the outlet of an air cleaner box. A frame may be integrally formed around the opening to support the HC trap protruding outward from the wall.

The present application provides various examples that may include a hose and a system. The hose may include a hose body, where an end segment of the hose body may be foldable over a clamp seat area of the hose body. There may be an opening in the end segment sized and shaped to provide access to a clamp, so as to better hold the clamp in place, while still enabling access.

A filter assembly for a motor-vehicle air cleaner may include a main filter, an auxiliary filter set apart from the main filter, and a filter mount fixed to and supporting the main filter and the auxiliary filter. In an example embodiment, the filter mount is fittable in and removable from a housing of the air cleaner, and includes a sealing element passing between the main filter and the auxiliary filter.
摘要:
An intake system for an engine including a first air filter assembly in fluidic communication with an intake manifold and a second air filter assembly spaced away from the first air filter assembly and in fluidic communication with the intake manifold.
摘要:
An inlet duct, an induction system, and a system are disclosed for directing an inlet flow into an inlet compressor for use in an internal combustion engine. An example inlet duct may include one or more relief features disposed on an inner surface of the inlet duct. The one or more relief features may be made integral with the inlet duct. The one or more relief features may be disposed to protrude into the inlet flow to cause the inlet flow to swirl before reaching the inlet compressor.
摘要:
A hydrocarbon (HC) trap positioned in an intake conduit of an engine is provided. The HC trap includes a stack of consecutively layered polymeric sheets with at least a portion of the sheets impregnated with a HC vapor adsorption/desorption material, the stack of sheets extending from a first exterior surface to a second exterior surface.

摘要:
An engine intake duct is formed by securing a hydrocarbon-adsorbing element to a frame to form an insert, positioning the insert in registry with a blow-molding core, placing a molten plastic parison and mold around the insert and core, and blow-molding the parison to form a shell engaging the frame to retain the insert with a surface of the insert exposed to a hollow interior of the shell.
