    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 refueling pipe structure of a fuel tank includes a tank body, and an a refueling pipe which is connected to the tank body to extend upwardly therefrom. The refueling pipe is provided at its upper end with a refueling port into which a refueling nozzle can be inserted. The structure includes a flow direction limiting device mounted within the refueling pipe in the vicinity of the refueling port for guiding a fuel flow from a tip end of the refueling nozzle toward an inner surface of the refueling pipe, while limiting the fuel flow in a gyrate direction along the inner surface of the refueling pipe. Thus, the generation of evaporated fuel within the refueling pipe during refueling can be inhibited, and fuel can be smoothly introduced into the tank body.

    摘要: An evaporative fuel-processing system for an internal combustion engine for use in a vehicle. A passage extends between the fuel tank and the intake passage, for guiding evaporative fuel generated in the fuel tank, for processing, across which a canister is arranged. A first passage and a second passage are connected to the canister. A first valve is arranged across the first passage to allow air to flow into the canister through the first passage and inhibit air containing evaporative fuel from being discharged from the canister through the first passage. A second valve is arranged across the second passage to inhibit air from flowing into the canister through the second passage and allow air containing evaporative fuel to be discharged from the canister through the second passage. A filter is arranged in the first passage.

    摘要: A vaporized fuel control valve for a fuel tank containing fuel to be supplied to an internal combustion engine, having a casing fastened to an upper surface of the fuel tank, and a float valve is housed in the casing such that it moves upward toward a seat in response to fuel level in the fuel tank. A diaphragm valve having a diaphragm is placed in the casing above the float valve for separating an interior of the casing to a first chamber communicating with a filler pipe of the fuel tank, and a second chamber communicating with the fuel tank through the float valve. The diaphragm valve opens to connect the second chamber with a canister such that vaporized fuel forced out of the fuel tank flows along a path through the float valve to the canister when the first chamber is supplied with atmospheric pressure, unless the float valve seats on the seat. In the valve, an intercepter such as a filter is placed in the path to intercept a fuel spray produced due to an impact when the float valve has seated on the seat, so as the fuel spray not to adhere to the diaphragm. As the interceptor, various partitions different in shape are used. With the arrangement, adherence of sprayed fuel, which otherwise degrades the diaphragm, is prevented.

    摘要: An evaporative fuel-processing system for an internal combustion engine comprises an evaporative emission control system including a canister having an air inlet port formed therein for introducing atmosphere into the canister and accommodating an adsorbent for adsorbing evaporative fuel generated in the fuel tank. A charging passage connects between the canister and the fuel tank. A two-way valve is arranged across the charging passage. A purging passage connects between the canister and the intake system. A purge control valve is arranged across the purging passage. An ECU carries out leak-checking of the evaporative emission control system. A negative pressure responsive-type bypass valve is arranged across a bypass passage bypassing the two-way valve. A negative pressure responsive-type vent shut valve is disposed to open and close the air inlet port of the canister. The ECU controls the bypass valve and the vent shut valve to open and close, by means of negative pressure developed within the intake system.
