摘要： PROBLEM TO BE SOLVED: To solve a problem of reduction of performance of an adsorbent which occurs when the adsorbent is fixed by applying adhesive to a nonwoven fabric arranged at a part of an intake passage for preventing the emission of fuel vapor from an intake system of an internal combustion engine into the atmosphere, which is the most common way conventionally. SOLUTION: In this evaporated fuel adsorbing device provided in at least a part of the intake system, both back and front sides of a granular adsorbent 100 like active carbon are clamped with two sheets of nonwoven fabric 101 having permeability, and outsides thereof are clamped with two honeycomb-like plates 102 to surely fix and support the adsorbent 100 in the case 103. The nonwoven fabric 101 or the like can also serve as an air cleaner element as a filter medium, and in some embodiments, the nonwoven fabric may be pleated and the adsorbent can be held in the space of the pleat.

摘要： PROBLEM TO BE SOLVED: To surely prevent outflow of fuel vapor to the atmosphere and to prevent clogging due to dust and damage of a filter by backfire, in an air cleaner for an internal combustion engine. SOLUTION: A sheet-shaped adsorption filter 20 for holding granulated activated carbon 22 by heat resistant net 26 and unwoven fabric 24 having porosity set to 90% or more is arranged on the internal combustion engine side of a filter element. Gasoline vapor evaporating after adhering to the inside of an engine when stopping the engine enters the air cleaner but does not flow to the atmosphere because gasoline vapor is adsorbed by granulated activated carbon 22. When backfire is generated, damage of the unwoven fabric 24 and the filter element is prevented because passing of fire is prevented by the heat resistant net 26. The porosity of the unwoven fabric 24 is set to 90% or more and thereby clogging due to dust can be prevented.

摘要： PROBLEM TO BE SOLVED: To surely prevent fuel vapor from being emitted from an intake passage into the atmosphere during the stop of an internal combustion engine. SOLUTION: A shut valve 14 is provided in an upstream side of a throttle valve 12 of an intake pipe 5 and in a downstream side of an air cleaner 13, opened with a signal of ECU, etc., on operating an engine, and closed on stopping the engine to prevent the fuel vapor in the intake pipe 5 from flowing out of the air cleaner 13. The fuel vapor confined in the intake pipe 5 is adsorbed by an adsorbent in a usual canister 2 through a normally opened type bypass valve 8. Although a blowby line 10 is also connected with the intake pipe 5 closed with the shut valve 14, since it is blocked with a normally closed type blowby valve 11 during the stop of the engine, there is no possibility of the blowby gas flowing into the intake pipe 5 to fix the shut valve 14, a throttle-valve 12 or the like.

摘要： PROBLEM TO BE SOLVED: To efficiently adsorb the evaporated fuel of an internal combustion engine and to efficiently eliminate the evaporated fuel from a fuel vapor adsorbing device even in an operating condition of small intake air quantity. SOLUTION: An adsorbing material 31 such as active carbon is mounted in a part of an intake passage 2, for example, inside of an air cleaner 21 to efficiently adsorb the evaporated fuel. In order to efficiently eliminate the evaporated fuel adsorbed to the adsorbing material 31 even in small intake air quantity, an intake throttle valve 61 is mounted at an upstream side of the adsorbing material 31, and the pressure near the adsorbing material 31 is reduced by throttling an opening. The elimination can be accelerated by directly heating the adsorbing material 31 in the intake passage by some heating means, or indirectly heating the adsorbing material 31 by heating the intake air.

摘要： PROBLEM TO BE SOLVED: To efficiently adsorb the evaporated fuel of an internal combustion engine and to efficiently eliminate the evaporated fuel from a fuel steam adsorbing device even in an operating condition of small intake air quantity. SOLUTION: An adsorbing material 31 such as activated carbon is placed on a part of an intake passage 2, for example, inside an air cleaner 21 to efficiently adsorb the evaporated fuel. In order to efficiently eliminate the evaporated fuel adsorbed by the adsorbing material 31 even when the intake air quantity is small, the elimination can be accelerated by directly heating the adsorbing material 31 in the intake passage by some heating means, or by indirectly heating the adsorbing material 31 by heating the intake air. The heating means is controlled in accordance with the operating condition of the internal combustion engine. For example, the heating means is controlled to be operated only in low rotation or low load where the intake air quantity of the internal combustion engine is reduced.

摘要： PROBLEM TO BE SOLVED: To provide an inexpensive filter element of good recycling property by using as the seal structure of a filter element a fiber collecting belt having air permeability and cushiony property. SOLUTION: A fiber collecting belt 6 formed, in an endless frame, of a sheet- shaped fiber assembly such as nonwoven fabric is laid on a clean side surface 3a of a flange 3 over its total length to join them by a means such as adhesion, ultrasonic fusion and heat fusion after a frame 2 and a reinforcing wall 5 are formed, or when the frame 2 and the reinforcing wall 5 are formed, the belt 6 is inserted into the flange 3. The fiber collecting belt 6 has air permeability and cushiony property, and it is pressed against the seal surface of an air cleaner housing to which a filter element is fitted and is compressed and deformed. Further, since the fiber belt 6 has air permeability, air is not prevented from entering the clean side from a clearance between an upper case and a lower case, But since the fiber collecting belt 6 itself is a filter medium and purifies air, no problem comes up.
