Abstract
(EN)
An onboard refueling vapor recovery system, comprising a main carbon canister (11) and a backup carbon canister (12) that are filled with activated carbon, a hydrocarbon sensor (13), a gravity valve (14), a fueling limiting exhaust valve (15) and a refueling vapor tube (16). The gravity valve (14) and the fueling limiting exhaust valve (15) are disposed at a top portion of a fuel tank (40) respectively. Two sides of the gravity valve (14) and the fueling limiting exhaust valve (15) are sealingly connected to the oil tank (40) and gas inlets of the refueling vapor tube (16) respectively. The main carbon canister (11) and the backup carbon canister (12) are sealingly connected to gas outlets of the refueling vapor tube (16) respectively. The main carbon canister (11) is in communication with an intake manifold (32) of an engine (30). The hydrocarbon sensor (13) is disposed in the main carbon canister (11), electrically connected to a vehicle control unit (20), and detects hydrocarbon content in the main carbon canister (11) and communicates to the vehicle control unit (20). Also disclosed is an automobile comprising the onboard refueling vapor recovery system.

L'invention concerne un système de récupération de vapeur de réapprovisionnement en combustible à bord, comprenant un réservoir de carbone principal (11) et un réservoir de carbone de secours (12) qui sont remplis de carbone activé, un capteur d'hydrocarbures (13), une soupape à gravité (14), une soupape d'échappement de limitation d'approvisionnement en combustible (15) et un tube de vapeur de réapprovisionnement en combustible (16). La soupape à gravité (14) et la soupape d'échappement de limitation d'approvisionnement en combustible (15) sont respectivement disposées dans une partie supérieure d'un réservoir de combustible (40). Deux côtés de la soupape à gravité (14) et de la soupape d'échappement de limitation d'approvisionnement en combustible (15) sont connectés de manière étanche au réservoir d'huile (40) et à des entrées de gaz du tube de vapeur de réapprovisionnement (16), respectivement. Le réservoir de carbone principal (11) et le réservoir de carbone de secours (12) sont connectés de manière étanche à des sorties de gaz du tube de vapeur de réapprovisionnement en combustible (16), respectivement. Le réservoir de carbone principal (11) est en communication avec un collecteur d'admission (32) d'un moteur (30). Le capteur d'hydrocarbures (13) est disposé dans le réservoir de carbone principal (11), est connecté électriquement à une unité de commande de véhicule (20), et détecte la teneur en hydrocarbures dans le réservoir de carbone principal (11) et la communique à l'unité de commande de véhicule (20). L'invention concerne également une automobile comprenant le système de récupération de vapeur de réapprovisionnement en combustible à bord.
