摘要： A lower wall partially defining a fuel storing chamber of a fuel tank curves upward in accordance a decrease in an amount of fuel stored in the fuel storing chamber. The volume of a gaseous space in the fuel storing chamber is reduced, in comparison with a fuel tank in which a lower wall does not deform, by an amount corresponding to a reduction of the volume of the fuel storing chamber achieved by the curvature of the lower wall. An amount of fuel not discharged from the fuel storing chamber via a fuel passage but remaining near a peripheral end portion of the lower wall of the fuel storing chamber due to the upward curvature of the lower wall is discharged via a residual fuel discharging pipe, so that the residual fuel amount of the fuel storing chamber is minimized.

摘要： A fuel-vapor emission-control system for an internal combustion engine which is capable of achieving both a reduction of the exhaust of vapor into the atmosphere and the prevention of an excessive increase in pressure within the fuel tank, regardless of the amount of internal pressure in the fuel tank, by providing on an atmospheric release port of the canister which adsorbs vapor adsorbed from the fuel tank of the internal combustion engine, thereby preventing release of the vapor into the atmosphere, an atmospheric release surface area changing valve which changes the surface area of an aperture to the atmosphere. The atmospheric release surface area valve operates to make the atmospheric release surface area larger when the internal pressure in the fuel tank is large than when the internal pressure in the fuel tank is small. The atmospheric release surface area changing valve can be configured as a mechanical type of pressure-sensitive valve which opens when the internal pressure in the canister exceeds a set value, and can also be configured as an electromagnetic valve, the degree of opening of which can be electrically varied in response to a detected value of vapor pressure within the system to thereby change the atmospheric release surface area.

摘要： A canister for treating fuel vapor generated in a fuel tank and for supplying fuel vapor to an intake system of an engine via a purge passage. First and second adsorbent compartments are defined in a casing by a partition for accommodating adsorbents. First and second dispersion compartments are defined in the casing for dispersing fuel vapor from the fuel tank. The first and the second dispersion compartments are located at one end of the first and second adsorbent compartments, respectively. A valve device is positioned at one side of the second adsorbent compartment for selectively opening and closing in accordance with the difference between internal and external pressures of the casing. A tank valve is connected to one side of the casing corresponding to the first adsorbent compartment for adjusting the pressure in the fuel tank. An external dispersion compartment is connected to a wall of the casing to communicate with the first dispersion compartment. A breather passage is connected to the external dispersion compartment for introducing fuel vapor into the canister from the fuel tank during refueling, and the external dispersion compartment has a cross sectional area larger than that of the breather passage.

摘要： 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.

摘要： 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.
