An air cleaner particularly disposed for an internal combustion engine is provided with a housing, a filter element disposed in the housing, and adsorbent disposed on the side of an outlet formed to the housing and adapted to adsorb an evaporated fuel invaded inside the housing through the outlet. The adsorbent includes an adsorbing material adsorbing the evaporated fuel and a pair of non-woven fabrics sandwiching the adsorbent material from both sides thereof, and at least one of the non-woven fabrics disposed on the outlet side includes a reinforcing material so as to be integrated with the non-woven fabric.

Air cleaner

The air-cleaner includes a housing. The air-cleaner includes a filter element located in the housing to filter air taken into the housing. The air-cleaner includes an adsorption element for adsorbing vaporized fuel flowing into the housing. The housing includes first and second housing components having open ends put on each other. The filter element is held between the first and second housing components, separating the housing into a clean side and a dust side. The adsorption element includes a frame at the periphery; and an adsorption portion located inside the frame. One of the first and second housing components as the clean side has an inner side back in the open end, the inner side having a mounting portion having the adsorption element mounted thereto. The mounting portion includes the adsorption element; and a support member placed thereon.

Air-cleaner

There is provided an air filter, which has a long lifetime and permits to capture effectively carbon particles and reduce costs. The air filter has the first filter layerimpregnated with oil and the second filter layer, which is provided on the downstream side of the first filter layerand serves as a lipophobic layer having an oil-repellent property. The filter material of the first filter layerhas a higher density than the filter material of the second filter material

Air filter

A canister includes a casing, a fuel reserve well defined at the bottom of the casing, an adsorbent layer provided in the casing for adsorbing fuel vapor, the adsorbent layer communicating with the fuel reserve well at a region of its lower portion and communicating with an atmosphere at its upper portion, a first communication passage defined so that the fuel reserve well communicates with a fuel system of an engine, and a second communication passage defined so that the fuel reserve well communicates with an intake system o f the engine. The second communication passage includes a purge chamber communicating with a region of the adsorbent layer other than the region of the adsorbent layer with which the fuel reserve well communicates, a first fuel outflow passage having a liquid fuel suction port open to the bottom of the fuel reserve well at its lower portion and a nozzle opening positioned in the purge chamber at its upper portion, and a second fuel outflow passage defined over the nozzle opening of the first fuel outflow passage for providing a fuel flow passage extending from the purge chamber to the suction system of the engine.
