    Patent number: 9695765
    Abstract: A vapor return system of a fuel vapor collecting tank includes a vapor outlet line with a first stop valve, which is arranged in the vapor outlet line of the fuel vapor collecting tank. A first vapor return branch is arranged between the vapor outlet line of the fuel vapor collecting tank and a charge air duct of a compressor in a turbocharger. A second vapor return branch is arranged between the vapor outlet line of the fuel vapor collecting tank and a fresh air suction duct of the compressor of the turbocharger. The first vapor return branch is connected by a first check valve to the charge air duct. The second vapor return branch is connected by a second check valve to a suction inlet of a venturi nozzle situated in a bypass line between the charge air duct and fresh air suction duct via a second stop valve.
