摘要： PROBLEM TO BE SOLVED: To realize a device for evaluating the evaporated gas treating instrument such as a canister simply and controllably and supply the fuel vapor of a desired flow rate to the canister quickly and continuously without using an oil supply facility. SOLUTION: A semi-closed up fuel tank 1 for storing a gasoline G which is a vapor supply source and communicating with a canister at a vapor port 13 and a gas introducing line 51 for introducing N2 to the gasoline G in the fuel tank 1 are provided as a vapor generation means for generating a fuel vapor. When N2 is introduced to the gasoline G, the saturated vapor state in the fuel tank 1 is collapsed and the gasoline G is evaporated in order to return to the saturated state. Thereby, by taking out this volume expansion amount from the vapor port 13, the fuel vapor of a desired amount responding to N2 introduction amount can be supplied to the canister 3.

摘要： PROBLEM TO BE SOLVED: To provide a canister having high adsorption and desorption performance. SOLUTION: In a canister 2, since a central part activated carbon layer 22 being the central part of an activated carbon layer is filled with activated carbon having thermal conductivity or heat capacity higher than that of a wall surface part activated carbon layer 21, heat generated at a central part is rapidly transferred to a wall surface part and heat is radiated from the wall surface part to the external part of the canister, whereby the temperature change margin of the central part is suppressed to a low value and the central part also obtains high performance. Further, by using activated carbon, having high heat capacity, in the central part, a similar effect is produced.

摘要： PROBLEM TO BE SOLVED: To miniaturize charcoal canistor and reduce a manufacturing cost by reducing an amount of fuel vapor flowing from a fuel tank to the charcoal canistor. SOLUTION: A sub-chamber 41 of small capacity is formed inside a fuel tank 1 by dividing the space by means of a partition plate 31. Fuel is supplied to the sub-chamber 41 trough an oil supply passage 11, while an inlet 5a of a vapor passage 5 connected to a canistor 13 is opened to an upper space 41a of the sub-chamber 41. Just supplied fuel of comparatively low temperature is stored in the sub-chamber 41. Gas containing fuel vapor introduced from a main chamber 42 to the canistor 13 through the vapor passage 5 passes through the sub-chamber 41 without fail. The fuel vapor is cooled and liquified in the sub-chamber 41. Only air containing no fuel vapor is made to flow to the canistor 13. The vapor passage 5 may be bent in the sub-chamber 41. Other cooling means and gas-liquid separation means may be arranged in the sub- chamber 41.

摘要： PROBLEM TO BE SOLVED: To provide a vaporized fuel treating device in which the concentration of a fuel vapor is accurately measured in real time. SOLUTION: A purge passage 15 and a blow-by gas discharge passage 23 are restricted by a butterfly valve 36. The amount of the pressure of a purge gas changed by the butterfly valve 36 is detected by a first pressure sensor 37, and the amount of the pressure of a blow-by gas changed by the butterfly valve 36 is detected by a second pressure sensor 38. Since the blow-by gas is lower in fuel vapor concentration than the purge gas, it is regarded as 100% air, and the fuel vapor concentration is calculated based on these two changed amounts of pressure detected by the pressure sensors 37, 38. Since these two changed amounts of pressure can be measured in real time, the fuel vapor concentration can be provided in real time. Also, since the effects of the atmospheric conditions are canceled, the concentration of the fuel vapor can be accurately measured. COPYRIGHT: (C)2007,JPO&INPIT
摘要翻译：要解决的问题：提供一种实时准确测量燃料蒸气浓度的汽化燃料处理装置。解决方案：吹扫通道15和窜气排放通道23由蝶形阀36限制。由蝶阀36改变的净化气体的压力量由第一压力传感器37检测，并且由第二压力传感器38检测由蝶阀36改变的窜气的压力量。由于窜缸气体的燃料蒸气浓度低于吹扫气体，因此被认为是100％空气，并且基于由压力传感器37,38检测的这两个改变的压力来计算燃料蒸气浓度。由于这两个改变的压力量可以实时测量，所以可以实时地提供燃料蒸气浓度。此外，由于大气条件的影响被消除，所以可以精确地测量燃料蒸气的浓度。版权所有（C）2007，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To reduce power loss, and secure a purge flow even when differential pressure between intake pressure in an intake passage and pressure on a canister side is small. SOLUTION: Evaporated fuel absorbed by an absorbent 31 of the canister 30 is forcibly desorbed by driving of a purge pump 40, and is introduced in the intake passage 11 of the internal combustion engine 10. At that time, intake pulsation of the intake passage 11 of the internal combustion engine 10 is introduced in a driving chamber 41 of the purge pump 40 and a partition wall 43 is moved. Thereby, a ratio of volume of the pump chamber 45 becomes variable. That is, the purge pump 40 utilizes movement of the partition wall 43 brought about by introduction of the intake pulsation of the intake passage 11 of the internal combustion engine 10 to perform pumping operation so that the power loss is reduced. Furthermore, even when the differential pressure between the intake pressure in the intake passage 11 of the internal combustion engine 10 and the pressure on the canister 30 side is small, a desired purge flow rate corresponding to an operation state of the internal combustion engine 10 can be secured.

摘要： PROBLEM TO BE SOLVED: To provide a failure diagnostic device in an evaporative fuel treatment system that detects a fuel leak more precisely. SOLUTION: The evaporative fuel that is lead from a fuel tank 13 into a canister 15 via an evaporative fuel passage is temporarily adsorbed on an adsorbent 16 placed therein. A later opening action of a purge control valve 19 allows the evaporative fuel that is desorbed off the adsorbent 16 to flow into an intake pipe 10. An ECU 26 is installed to determine whether a fuel leak occurs in that closed-circuit space which the purge control valve 19 defines by closing the evaporative fuel path leading from the fuel tank 13 to the intake pipe 10 by way of the canister 15, by measuring a drop P1 in the internal pressure of the fuel tank 13 after the lapse of a preset time T1 from the time point when the closed-circuit space is pressurized up to a preset pressure P4 and then a solenoid valve 25 connected in series to a reference orifice 24 is opened, and also a drop P2 in the internal pressure of the fuel tank 13 after the lapse of the same time T1 from the time point when the closed-circuit space is pressurized up to the same pressure P4, and thereafter comparing a value P3, or (P1-P2), and the value P2 to each other.

摘要： PROBLEM TO BE SOLVED: To control diffusion of evaporated fuel in a canister during the decrease of fuel temperature when an engine is stopped and prevent the occurrence of a trouble, such as blow-by of evaporated fuel. SOLUTION: A canister 10 is connected to a fuel tank 5 through a first evaporation passage 8 and a tank internal pressure regulation valve 11 is disposed in the evaporation passage 8. An atmosphere port 13 to introduce outside air is formed in the canister 10 and an electromagnetically-driven atmosphere intake valve 14 is disposed at the tip part of the atmosphere port 13. An ECU 20 controls opening and closing operation of the atmosphere intake valve 14 so that an internal pressure in a tank is fluctuated with a given width in a negative pressure region during the decrease of fuel temperature when an engine is stopped. In this case, through opening of the atmosphere intake valve 14, high speed outside air flows in the canister 10 and this constitution performs back purge of evaporated fuel and narrows an evaporated fuel diffusion layer in the canister 10.
