摘要： A canister for preventing diffusion of fuel vapor to atmosphere is disclosed herein. The canister includes a first case having an adsorbent material, such as activated charcoal, therein and a second case also having an adsorbent material therein. The two cases are joined by a passage having a valve disposed therein. The valve regulates the airflow between the two cases. The first case is connected to the valve, a gas tank, and an engine, while the second case is connected to the valve and to atmosphere. During a refueling operation, the valve is operated so as to allow air to flow from the tank, through the first case and out to the atmosphere through the valve, without passing through the second case.

摘要： A canister is provided between a fuel tank and an intake conduit of an engine so that fuel vapor generated in the tank and adsorbed in the canister is purged into the intake conduit. In correcting a fuel quantity in accordance with a purge quantity, the fuel quantity is compensated for by a canister piping condition such as a pressure loss and/or a purge delay. A first fuel correction coefficient is calculated from canister pressure, intake pressure and atmospheric pressure. The first coefficient may be calculated in association with an idling speed control value. A second fuel correction coefficient is calculated from changes in purge flow quantity and canister pressure. The second coefficient may be calculated in association with an air-fuel ratio feedback control value.

摘要： When refueling is started, a purge valve is closed, and power is supplied to a coil of a solenoid so that a constant pressure operating valve of an atmospheric escape valve is opened. When the temperature of the fuel tank rises while an engine is at a stop, fuel evaporation gas generates and the pressure within the fuel tank increases. When the differential pressure between the in-tank pressure and the atmospheric pressure increases, a first communication passage is opened, and the pressure is released to the outside. Thus, the pressure within the fuel tank can be maintained at an appropriately high pressure level while the vehicle is at a stop, and the quantity of the fuel evaporation gas generating while the vehicle is at a stop can be controlled.

摘要翻译： 当加油开始时，关闭排气阀，向螺线管的线圈供电，使得大气泄放阀的恒压操作阀打开。 当发动机处于停止状态时燃料箱的温度升高，产生燃料蒸发气体，燃料箱内的压力增大。 当舱内压力和大气压力之间的压差增加时，第一连通通道打开，并且压力释放到外部。 因此，能够在车辆停止时将燃料箱内的压力保持在适当的高压位置，并且可以控制在车辆停止时产生的燃料蒸发气体的量。

摘要： A fuel vapor purging system includes a container in which a set of divided chambers are formed by partition walls. Absorbent is disposed in the divided chambers. The divided chambers are sequentially connected to form a zigzag passage. Fuel vapor can enter the container from a fuel tank via a vapor line connecting the fuel tank and the container. In the container, an end of the vapor line faces the divided chamber which occupies an end of the set of the divided chambers. In the container, the fuel vapor is absorbed by the absorbent. Air can escape from the container via an opening in the container. The fuel vapor can be separated from the absorbent. The separated fuel vapor can be drawn into a suitable drawing device such as an engine air induction device via a purge line connecting the container and the drawing device. Fresh air can flow into the container via an air inlet provided on the container. Among the divided chambers, at least the divided chamber which occupies the end of the set of the divided chambers has a cross-sectional area equal to or smaller than 40 cm.sup.2.

摘要： A canister for use in an evaporative emission control system of an automotive vehicle is provided which includes a box-like casing, an inlet port formed in one end wall of the casing through which fuel vapors generated within a fuel tank are drawn into the canister, and a plurality of vapor-adsorbing passages each of which is filled with activated carbon and has a given length through which the fuel vapors drawn through the inlet port flow. The vapor-adsorbing passages are all arranged within said casing in parallel to each other. This arrangement allows the casing to be of a flat shape which facilitates easy installation of the canister within a flat space around a fuel tank.

摘要： A canister which can control the diffusion of evaporated fuel to surely prevent the evaporated fuel from blowing through into the atmosphere has a main chamber having therein a first adsorbent layer for adsorbing evaporated fuel and including an evaporated fuel lead-in port and a purge port, a subchamber having therein a second adsorbent layer for adsorbing evaporated fuel and including an atmospheric air lead-in port, and an air chamber communicating with the main chamber and the subchamber are provided in a casing of a canister. The air chamber is divided into three parts: a first chamber at the side of the main chamber, a second chamber at the side of the subchamber and a third chamber between the first and second chambers. A nonlinear communication passage is formed inside of the third chamber by dividing the third chamber with a partition wall having its both ends opened to the first chamber and the second chamber respectively. Since the communication passage can be sufficiently long, a canister with both diffusion prevention and low pressure loss can be obtained.

摘要： The electromagnetic valve has an electromagnetic actuator for operating a valve. The electromagnetic actuator has a movable core that reciprocally moves in an axial direction. A stator core has an attracting portion. The attracting portion has a conical portion that is defined by a uniform diameter inner surface and an outwardly inclined outer surface. The outer surface has a smaller diameter at a position closer to an initial position of the plunger. Therefore outer diameter of the conical portion is increased in an attracting direction of the plunger. Moreover, increasing rate of the outer diameter is decreased in the attracting direction. Therefore the outer surface has a greater inclination angle at a position closer to an initial position of the plunger.

摘要： An electric motor is placed on an upstream side of an exhaust gas recirculation passage of a housing in a direction that is parallel to an intake air flow direction. A first heat release part on a motor housing part of the housing is placed on an upstream side of an exhaust suction aperture in a direction of an intake air flow. A heat release of the electric motor is promoted by direct contact between a new intake air with much lower temperature than an EGR gas and the first heat release part of the motor housing part. Therefore, on the upstream side of the exhaust suction aperture in the direction of the intake air flow, the electric motor can be cooled by the new intake air. By utilizing the intake air suctioned into an inlet port of an engine, the electric motor and the like can be efficiently cooled.

摘要： According to the present invention, an evaporative fuel absorbing chamber absorbingly treating evaporative fuel, a second atmospheric chamber communicating with the evaporative fuel absorbing chamber, and a first atmospheric chamber separated from the second atmospheric chamber with a partition wall are formed in a case. An upper cover for forming the upper wall of the first atmospheric chamber has a cylindrical convex portion extending inside the first atmospheric chamber. When the upper cover is fixed after inserting the bottom end of an eletromagnetic valve into a communicating hole of the partition wall, the top end of the electromagnetic valve is fastened to the cylindrical convex portion. Thus, the electromagnetic valve is prevented from being clattered, and air leakage from between the communicating hole and the electromagnetic valve can be reduced. An air passage from the electromagnetic valve to the evaporative fuel absorbing chamber is formed in the canister, so that the evaporative fuel can be prevented from leaking from the gas passage.
