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.
