摘要： In an evaporative fuel processing device, a canister is divided into first, second, third and fourth chambers by partition walls. A control valve is provided in a communication passage which connects the second and third chambers to each other. A first charge passage is connected to an upper space in a fuel tank and to a port in the third chamber, and a second charge passage is connected to a fuel supply valve for the fuel tank and to a port in the first chamber. Further, a purge passage is connected to an intake passage of an internal combustion engine and to a port in the first chamber. The control valve is connected to an electronic control unit, and opened during refueling and during traveling of a vehicle and closed during parking of the vehicle. Thus, it is possible to reliably prevent an evaporative fuel from being released to the atmosphere, while the capacity of the canister to a minimum.

First and second filters are mounted in the first chamber in a fashion abutting on the plurality of the first and second protuberances, respectively. A first space is defined in the top wall between the first filter and the portion of the inner surface of the top wall, and a second space is defined in the vertical wall between the second filter and the portion of the inner surface of the vertical surface and communicates with the first space. A charging port and a purging port are each formed in the top wall at a location corresponding to the first chamber and each open into the first space. An atmospheric air port is formed in the top wall at a location corresponding to the second chamber.

摘要： In an evaporative fuel processing device, an evaporative fuel passage communicating at one end to an upper space in a fuel tank is connected at the other end to a refueling line at a location corresponding to a negative pressure introducing hole provided in a lower portion of a tip end of a nozzle during refueling by a refueling nozzle which is constructed so that the refueling by the refueling nozzle is automatically stopped in response to a fuel liquid level reaching the negative pressure introducing hole during refueling. The draft resistance of an evaporative fuel passage interconnecting an inlet of the refueling line and a tank body is set larger than the draft resistance of an evaporative fuel passage interconnecting the tank body and a canister. Thus, the releasing of evaporative fuel from the fuel tank during refueling is effectively inhibited without use of a potentially unreliable seal.

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-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.
