ABSTRACT:
A system for managing fuel-vapor emission from a fuel tank of a vehicle using a vortex-effect flow separator coupled in the fuel-vapor purging system of the vehicle. The warmer-flow outlet of the separator is coupled to the engine intake, and the cooler-flow outlet is coupled to the fuel tank. In this way, less fuel vapor is delivered to the engine intake.
