摘要： An evaporation fuel processing system is equipped with a vapor passage, a canister, a purging passage, a purge control valve, a filling amount detector, and an ECU. The ECU comprises an adsorption amount detecting circuit that detects the adsorption amount of an evaporation fuel, which is adsorbed by the canister upon filling of the fuel at a time when a fuel is filled into a fuel tank, a breakthrough time calculating circuit that calculates a time, based on the detected adsorption amount, at which the canister would experience breakthrough in the event that the evaporation fuel were not purged into an engine from the canister, and a control circuit that carries out purge processing by the purge control valve based on the calculated time.

摘要： An evaporated fuel treatment apparatus includes a control valve having a dead zone range in which an evaporated fuel is blocked even if the opening angle is increased from a close position in opening direction and a communicating range in which the evaporated fuel is allowed to flow therethrough when opening angle is increased from the dead zone range. A control unit determines whether the opening angle is switched between the dead zone range and the communicating range. The switching is determined on the basis of a pressure inside the fuel tank detected with a pressure sensor and an air-fuel ratio detected by an air-fuel ratio sensor. A control valve installed in a communication path between a fuel tank and a canister is prevented from being seized.

摘要： In a fuel vapor release suppression system for a fuel tank, a main tank and a sub tank communicate with each other, and the sub tank and a canister communicate with each other. When the main tank has a higher temperature, fuel vapor of the main tank is supplied to the sub tank where the fuel vapor is liquefied. When the main tank has a lower temperature, fuel vapor of the sub tank is supplied to the main tank. At this time, low concentration fuel vapor is supplied from the canister to the main tank, thereby accelerating generation of fuel vapor corresponding to sub tank fuel vapor pressure, so that the sub tank fuel vapor pressure decreases. Therefore, liquefaction is accelerated in the sub tank when the main tank temperature increases. Thus, fuel vapor generated in a fuel tank is effectively liquified irrespective of ambient air temperature.
