Abstract
An engine intake system has an imperforate walled pit disposed at an elevation vertically below a bottom wall in a main passageway that contains an entrance opening into the pit. Gaseous, heavier-than-air, hydrocarbon that is migrating upstream within the main intake passageway from an engine end of the main passageway along the bottom wall toward the entrance opening will fall through the entrance opening into the pit upon encountering the entrance opening. A medium, such as activated carbon, disposed within the interior space collects gaseous hydrocarbon that has fallen into the pit.
