    • A fuel vapor control system that is adapted for use with internal combustion engines includes a fuel tank, an evaporative emission control device containing activated carbon and including a first orifice that fluidly communicates with the fuel tank via a vent line. A second orifice in the control device is open to the atmosphere. A purge tube is between a filter element and a venturi section of the engine and fluidly communicates with a third orifice in the control device via a vapor line. Fuel vapors are absorbed by the activated carbon when the engine is not running, and the carbon releases the fuel vapors to the engine via the purge tube when the engine is running.
    • 适于与内燃机一起使用的燃料蒸汽控制系统包括燃料箱,含有活性炭的蒸发排放控制装置,并且包括通过排气管线与燃料箱流体连通的第一孔。 控制装置中的第二个孔口对大气敞开。 吹扫管位于发动机的过滤元件和文丘里管部分之间,并通过蒸气管线与控制装置中的第三孔流体连通。 当发动机不运行时,燃料蒸气被活性炭吸收,并且当发动机运行时,碳通过吹扫管将燃料蒸汽释放到发动机。

    • A fuel tank for an engine that includes an air cleaner assembly and an air-fuel mixing device. The fuel tank includes a first tank portion, a second tank portion connected to the first tank portion to define a fuel chamber, and a canister at least partially formed as part of the first tank portion. A first flow path is at least partially formed as part of the first tank portion. The first flow path provides fluid communication between the fuel chamber and the canister. A second flow path is at least partially formed as part of the first tank portion to provide fluid communication between the canister and at least one of the air-fuel mixing device and the air cleaner assembly.
    • 一种用于发动机的燃料箱,其包括空气滤清器组件和空气 - 燃料混合装置。 燃料箱包括第一罐部分,连接到第一罐部分以限定燃料室的第二罐部分,以及至少部分地形成为第一罐部分的一部分的罐。 第一流路至少部分地形成为第一罐部分的一部分。 第一流路提供燃料室和罐之间的流体连通。 第二流路至少部分地形成为第一罐部分的一部分,以提供罐与空气 - 燃料混合装置和空气滤清器组件中的至少一个之间的流体连通。
