    • A fuel tank body has a double-layer structure composed of an inner tank shell and an outer tank shell, so that an inter-tank-shell space is formed therebetween. Because heat of fuel in the fuel tank body is discharged into the inter-tank-shell space, the temperature of fuel in the fuel tank body is prevented from rising. If the pressure in a canister becomes negative due to a negative pressure in an intake system of an engine, more specifically, a negative pressure in a surge tank leading to an air cleaner, high-temperature air in the inter-tank-shell space between the inner tank shell and the outer tank shell flows into the canister. On the other hand, low-temperature air flows from the air cleaner into the inter-tank-shell space which has become negative in pressure.
    • 燃料箱体具有由内罐壳体和外罐壳体构成的双层结构,从而在其间形成有槽间空间。 由于燃料箱体内的燃料的热量被排出到舱间空间内,因此能够防止燃料箱体内的燃料的温度上升。 如果由于发动机的进气系统中的负压引起的罐中的压力变为负值,更具体地说,在通向空气净化器的缓冲罐中的负压,在罐内空间内的高温空气 内罐壳体和外罐壳体流入罐体。 另一方面,低温空气从空气净化器流入在压力变成负值的槽间空间。

    • A cooling unit is mounted to an upper wall of a fuel tank so as to cool fuel. A control valve and a vent valve are disposed in a vapor line extending from a float valve to a canister. The control valve and the vent valve are disposed in parallel with one another and constitute a valve member. A cooling unit is mounted to an evaporation passage between a float valve and the valve member. Operation of the cooling units serves to cool fuel and inhibit generation of vapor. If the pressure in the fuel tank exceeds a control pressure, a control circuit opens the control valve and performs control such that the pressure in the fuel tank becomes lower than a running-state relief pressure.
    • 冷却单元安装到燃料箱的上壁以便冷却燃料。 控制阀和排气阀设置在从浮阀延伸到罐的蒸气管线中。 控制阀和排气阀彼此平行设置并构成阀构件。 冷却单元安装在浮阀和阀构件之间的蒸发通道上。 冷却单元的操作用于冷却燃料并抑制蒸气的产生。 如果燃料箱中的压力超过控制压力,则控制电路打开控制阀并执行使得燃料箱中的压力变得低于运行状态的释放压力的控制。
