A fuel adsorbent memberis arranged in a housingat a position downstream from a filter element. The fuel adsorbent memberadsorbs evaporative fuel. An air cleaner is configured in such a manner that, when receiving a backfire pressure Pfrom an engine, the fuel adsorbent memberis held in the state secured to the housing.

A fuel adsorption sheet includes a sheet base. A fuel adsorbent and a reinforcing net are arranged in the sheet base. The reinforcing net is formed by a plurality of cords extending in at least three directions along a surface the sheet base. The fuel adsorption sheet is arranged in an air passage of an air cleaner. The sheet base includes a pair of covering sheets. The covering sheets have central portions for holding the fuel adsorption member and the reinforcing net and peripheral portions for holding only the reinforcing net. A fastening portion is defined in the peripheral portions of the sheet base when the covering sheets are bond together.

A housingaccommodates a pleated filter element. A fuel adsorbent memberis arranged in the housingat a position downstream from the filter element. The fuel adsorbent memberadsorbs evaporative fuel leaking from an engine. The fuel adsorbent memberincludes holding pleats. Each of the holding pleatsis received in the space between an adjacent pair of the element pleatsof the filter element. This maintains the interval between the element pleats. The holding pleatsare formed by folding the fuel adsorbent member

Air cleaner

A fuel vapor adsorbing device () for adsorbing residual fuel vapors that remain in an intake conduit () of an induction system of an internal combustion engine when the internal combustion engine is stopped may include an adsorbing member (') that is constructed to adsorb the residual fuel vapors and is disposed along an inner wall surface of the intake conduit. The adsorbing member is arranged and constructed to form a supplemental intake path (T, T&#x2032;, T&#x2032;&#x2033;) between the adsorbing member and the inner wall surface of the intake conduit, so that intake air of the engine can flow through the supplemental intake path.

Fuel vapor adsorbing devices

An evaporative fuel adsorbent, which adsorbs evaporative fuel, is positioned substantially parallel to a sidewall surfaceof a surge tank. A retention memberis positioned between the sidewall surfaceand evaporative fuel adsorbentto prevent oil, which runs down on the sidewall surface, from adhering to the evaporative fuel adsorbent. The evaporative fuel adsorbentis mounted on the sidewall surfaceof the surge tankvia the retention member

Evaporative fuel adsorption device

An evaporated fuel adsorbing apparatus for an engine intake passage includes a layer of activated carbon disposed in the engine intake passage for adsorbing evaporated fuel. The activated carbon includes activated carbon pellets having pores. At least one of an average pellet size and an average pore size of the activated carbon is varied in an intake gas flow direction of the engine intake passage. More particularly, an average pore size of a first portion of the activated carbon located in an atmosphere side portion of the layer is greater than an average pore size of a second portion of the activated carbon located in an engine side of the layer. An average pellet size of the first portion of the activated carbon is smaller than an average pellet size of the second portion of the activated carbon.

Evaporated fuel adsorbing apparatus for an engine intake passage

A shut off valve is provided in an intake line farther upstream than a throttle valve of the intake passage and farther downstream than an air cleaner. This shut off valve is opened by a signal or the like from an ECU when an engine is operating. Further, the shut off valve closes when the engine is stopped so as to suppress evaporative fuel inside the intake passage from flowing outside through the air cleaner. The evaporative fuel trapped inside the intake passage passes through a bypass passage that provides communication between the intake passage and the canister, and is then adsorbed with an adsorbent in the canister. A blow-by passage is also connected to the intake passage that is closed off by the shut off valve. Because the blow-by passage is closed off by a blow-by valve, which is closed during normal operation when the engine is stopped, sticking of the shut off valve and the throttle valve and the like due to the inflow of blow-by gas into the intake passage is inhibited.

Evaporation fuel processing unit

An adsorbent for adsorbing fuel vapors is disclosed. The adsorbent is to be disposed in an inlet system of an internal combustion engine. It has pores, and 50% by volume or more of the pores have a pore diameter falling in a range of from 1.4 to 2.8 nm. It exhibits a unit pore volume of 0.3 mL or more with respect to 1 mL thereof. It is formed as a particle. It exhibits high performance on adsorbing fuel vapors, and shows high durability even when it is used for long period of time.

Adsorbent for adsorbing fuel vapors

A throttle valve is opened after stopping an engine to prevent the valve from sticking. Then, when a temperature of the valve has become lower than the polymerization temperature, the valve is closed to seal the vapor of the HCs in a surge tank downstream. Changes in the temperature of the valve are, for example, estimated based on a temperature of an intake air detected by an intake temperature sensor.

Hydrocarbons emission preventive apparatus in intake system for internal combustion engine and method thereof

An intake device for an internal combustion engine has: a first intake pipe which is connected to the engine so as to conduct an intake air to the engine, and which has an opening portion that is provided in an upstream-side lower portion of the first intake pipe located at an upstream side in a flowing direction of the intake air; and a second intake pipe which has a downstream-side end portion that faces an upstream-side end portion of the first intake pipe, with a gap formed therebetween, and which conducts the intake air to the first intake pipe. An unburned gas reflux passage is provided for conducting an unburned gas from the engine to the first intake pipe. A container surrounds the gap and the opening so as to receive the unburned gas flowing from the opening portion. Thus, it becomes possible to prevent release of unburned gas into the atmosphere by performing a simple process on a conventional structure.

Intake device for internal combustion engine

A filter and a method of manufacturing the filter which is formed by spinning a fiber in a semi-molten state onto a mold such that the mold is provided as a filter structural member. The method obviates the need to remove the filter from the mold and thus simplifies the manufacture of the filter.

Filter and method for manufacturing the filter

A filter portion of a filter includes a plurality of bag-like members. The bag-like members are formed in a container shape having an opening and disposed with intervals therebetween. The periphery of the opening of each bag-like member is supported by a supporting member, and the bag-like members are mutually connected by the supporting member. Consequently, the strength of the filter portion comprising the bag-like members is improved.

Filter and manufacturing method thereof

An HC adsorbing sheet inside an air cleaner is disposed such that a large amount of activated carbon is contained on the side of an engine and that a small amount of activated carbon is contained on the other side of the engine. Thus, the HC adsorbing sheet can efficiently adsorb evaporative fuel. That is, by changing the amount of activated carbon contained in accordance with differences in concentration of evaporative fuel, it becomes possible to prevent the pressure loss in an intake system from increasing. On the other hand, one end of a second intake pipe extends to a region where the amount of activated carbon contained in the HC adsorbing sheet is large, whereby it becomes possible to concentratively supply activated carbon with intake air in the region where the large amount of activated carbon is contained. Therefore, the efficiency in purging evaporative fuel can be prevented from declining.
