摘要： An evaporative emission control system includes a fuel tank, a canister, a normally-closed control valve, a filler pipe, and a breather pipe. The fuel tank is to store fuel. The canister is to adsorb evaporative fuel generated in the fuel tank. The normally-closed control valve is provided in a vapor passage connecting the fuel tank to the canister. The fuel is delivered to the fuel tank through the filler pipe. The breather pipe includes a communicating passage, an opening, and at least one hole. The communicating passage connects the fuel tank to the filler pipe. The opening is provided at a first end of the breather pipe in the fuel tank. The opening is located below a predetermined fuel level in the fuel tank. The at least one hole is located above the predetermined fuel level in the fuel tank.

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： An evaporated fuel treatment apparatus including a canister for adsorbing an evaporated fuel in a fuel tank, a control valve at a vapor path communicating with a fuel tank and a canister, has a dead-zone range where a flow of the evaporated fuel is blocked even if an opening angle of the control valve is increased in an open direction from zero opening angle, and allows the evaporated fuel to flow through over the dead-zone range. The control unit increases the opening angle from substantially zero to a predetermined angle in the dead-zone range and stands by prior to the opening control, and increases the opening angle from the predetermined angle upon the opening control. An output value by control unit set in the dead-zone range is compared with a detected value to detect a failure of the control valve.

摘要： A vapor processing apparatus includes a tank-inner-pressure detector, an atmospheric-pressure detector, a canister, a control valve and a controller. The tank-inner-pressure detector is configured to detect tank inner pressure of a fuel tank retaining fuel to be supplied to an engine. The atmospheric-pressure detector is configured to detect atmospheric pressure. The canister is configured to adsorb and collect vapor generated in the fuel tank. The control valve is disposed in a vapor channel connected to the fuel tank. The controller is configured to control opening and closing of the control valve based on a value detected by the tank-inner-pressure detector, a value detected by the atmospheric-pressure detector, and a correction value learned in advance, when in a predetermined state.
