Abstract:
1. A system for managing fuel-vapor emission from a fuel tank of a vehicle, the system comprising: a vortex-effect, flow-separator tube having a warmer-flow outlet arranged downstream of a conical nozzle at a first end of the tube, a cooler-flow outlet arranged at a second end of the tube, opposite the first end, and an inlet to which an inlet gas flow entraining fuel vapor is admitted, the flow-separator tube configured to warm a gas flow emerging from the warmer-flow outlet and to cool a gas flow emerging from the cooler-flow outlet; a first path coupling the warmer-flow outlet to an intake of an engine of the vehicle; a second path coupling the cooler-flow outlet to the fuel tank; and a third path coupling the fuel tank to the inlet.
