摘要： An evaporative emission control system for an internal combustion engine includes a canister for adsorbing evaporative fuel generated in the fuel tank, a communication passage connecting between first and second adsorbent chambers defined in the canister, a first introducing passage for introducing the generated evaporative fuel into the canister on an occasion other than at fueling, a purging passage for purging the evaporative fuel adsorbed into the canister to the intake passage, and an air-inlet passage communicating with the atmosphere. The first introducing passage, the second air-inlet passage and the purging passage are connected to the first adsorbent chamber. A second introducing passage is connected to the second adsorbent chamber, for introducing the evaporative fuel thereinto at refueling, and an additional passage having a cross sectional area larger than that of the air-inlet passage and communicating with the atmosphere is connected to the first adsorbent chamber. A first valve is arranged across the air-inlet passage, for closing the same at refueling, and a second valve across the additional passage, for opening the same at refueling.

摘要： An evaporative fuel-adsorbing device adsorbs evaporative fuel generated from a fuel tank of an internal combustion engine. A partition divides the interior of a casing at least into a first adsorbent chamber and a second adsorbent chamber. Adsorbents are charged in the first adsorbent chamber and the second adsorbent chamber, respectively, for adsorbing the evaporative fuel. The evaporative fuel from the fuel tank is permitted to flow into the first adsorbent chamber via a charging port provided therein. The evaporative fuel desorbed from the adsorbents in the adsorbent chambers are permitted to flow out of the first adsorbent chamber via a purging port provided therein. The second adsorbent chamber is communicated with the atmosphere via an air-inlet port. The maximum flow rate of the evaporative fuel through a communication passage connecting between the first and second adsorbent chambers is changed in dependence on at least one of an amount of the evaporative fuel flowing into the evaporative fuel-adsorbing device and an amount of the evaporative fuel flowing out of same. An evaporative emission control system incorporating the evaporative fuel-adsorbing device is also provided.

摘要： An evaporative fuel-processing system for an internal combustion engine includes a canister accommodating an adsorbent therein, for adsorbing evaporative fuel generated in a fuel tank of the engine, and a charging passage connecting between the canister and the fuel tank. A shutter valve is arranged in a fuel supply pipe of the fuel tank in the vicinity of an inlet end thereof, for isolating the interior of the fuel supply pipe from the atmosphere, and the shutter valve is disposed to be opened by the tip of a refueling gun when the latter is inserted into the fuel supply pipe. A pressure-intake port section is arranged in the fuel supply pipe at a side of the shutter valve closer to the main body of the fuel tank, for taking in pressure within the fuel supply pipe. A diaphragm valve is arranged in the charging passage, which has a casing, a diaphragm defining the interior of the casing into a first chamber and a second chamber, a valve element displaceable together with the diaphragm, an evaporative fuel outlet disposed to be opened and closed by the valve element, and a spring urging the valve element in a direction of closing the evaporative fuel outlet. The first chamber communicates with the pressure-intake port section, and the second chamber communicates with the interior of the fuel tank.
