    • In a fuel supply system for an internal combustion engine including a fuel tank with an activated carbon canister in communication therewith for removing hydrocarbons from the fuel tank venting gases, the activated carbon canister is vented selectively by compressed air conducted from a pressurized air supply for the engine through the canister under the control of a valve which, during flushing of the activated carbon canister, blocks the communication line between the fuel tank and the activated carbon canister and by which the fuel vapors are returned to an engine intake manifold via a suction line, or during normal operation of the engine, by air sucked through the activated carbon container to an inlet manifold of the engine. The activated carbon container can be flushed with positive pressure when the engine is operated with supercharging and with negative pressure when the engine is operated in a normally aspirated fashion.
    • 在用于内燃机的燃料供应系统中,包括具有与其连通的活性炭罐的燃料箱,用于从燃料箱排放气体中除去碳氢化合物,活性炭罐由压缩空气供给的压缩空气选择性地排放, 发动机在阀门的控制下通过罐的控制,该阀在冲洗活性炭罐期间阻塞燃料箱和活性炭罐之间的连通管线,并且燃料蒸汽经由吸入管路返回到发动机进气歧管 或者在发动机的正常操作期间,通过从活性碳容器吸入到发动机的入口歧管的空气。 当发动机以正常吸气的方式操作时,发动机以增压和负压运行时,活性炭容器可以以正压冲洗。
