Fuel vapor management system

摘要

A fuel vapor management system for an automotive vehicle includes a vapor tower in fluid communication with a vapor purge outlet of a fuel pump. A fluid treatment section, such as a screen, is disposed between the fuel pump vapor purge outlet and the vapor tower. The fluid treatment section reduces the size and momentum of purged vapor bubbles such that the purged vapor bubbles in the vapor tower may rise in the vapor tower and separate from liquid fuel thereby, allowing liquid fuel to flow out of the vapor tower and allowing fuel vapor to escape from the vapor tower away from the inlet of the fuel pump inlet.
