Title
(EN) FUEL VOLATILITY SENSOR SYSTEM
(FR) SYSTÈME DE DÉTECTION DE VOLATILITÉ DE CARBURANT
Abstract
(EN) A fuel vapor management system for a vehicle includes a vehicle fuel pump assembly and a fuel volatility sensor system having a test chamber and a valve. The test chamber is fluidly coupled to the fuel pump assembly to receive a flow of fuel therefrom, the valve configured to selectively isolate and seal a portion of the fuel flow within the test chamber to determine fuel volatility of the portion of the fuel flow.
(FR) L'invention concerne un système de gestion de vapeur de carburant pour un véhicule, comprenant un ensemble pompe à carburant de véhicule et un système de détection de volatilité du carburant pourvu d'une chambre d'essai et d'une vanne. La chambre d'essai est en communication fluidique avec l'ensemble pompe à carburant pour recevoir un flux de carburant en provenance de celle-ci, la vanne est configurée pour isoler sélectivement et sceller une portion du flux de carburant à l'intérieur de la chambre d'essai afin de déterminer la volatilité du carburant de la portion de flux de carburant.
