Abstract
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.
