In a saddle-ride type vehicle in which an intake device is arranged at a position covered by a fuel tank from above, the intake device including: an air cleaner; a connecting tube having an upstream end thereof connected to the air cleaner; a throttle device including a throttle valve and connected to a downstream end of the connecting tube; and a resonator, a curved portion bulged upward and curved in a chevron shape is formed in the connecting tube, and the resonator arranged between the fuel tank and the connecting tube is connected to the connecting tube on the air cleaner side further than a top portion of the curved portion as seen in a side view of the vehicle.

An air cleaner for an internal combustion engine includes a first housing having an inlet and an upper opening, a second housing having an outlet and a lower opening, a filter element arranged between the upper opening of the first housing and the lower opening of the second housing. The first housing includes a sound reducing wall portion. The sound reducing wall portion has a sound absorbing layer, which is made of nonwoven fabric, and an inner covering layer, which is fixed to the inner surface of the sound absorbing layer and made of a material having a lower air permeability than that of the sound absorbing layer.

In an air cleaner, an air cleaner case having an upper opening which opens upward is formed. The air cleaner case is formed of a front wall, a rear fender, and right and left side covers. The upper opening is closed by a seat. A sound absorbing member is bonded to a bottom plate of the seat and housed in an air cleaner space. The intake noise in the air cleaner is absorbed by the sound absorbing member.

An apparatus and a method are provided for an aircharger air intake system for filtering and conducting an airstream to an air intake of an engine. The aircharger air intake system includes an air filter comprising a filter medium configured to entrap particulates flowing within the airstream. An air box comprising one or more sidewalls and a mount wall is configured to support the air filter within an engine bay. The air box is configured to be mounted, or fastened, onto the engine. An intake tube is coupled with the air filter and configured to conduct the airstream to the air intake of the engine. The intake tube is configured to be coupled with an air temperature sensor or a mass air sensor of the engine. An adapter is configured to couple the intake tube with the air intake.

The present invention discloses an air cleaner for a vehicle. An air cleaner for a vehicle according to an embodiment of the present invention includes: a housing having an intake port for suctioning air and an outtake port for supplying the air suctioned through the intake port to an engine system of the vehicle; and an element installed in the housing to filter the air suctioned through the intake port, and the air cleaner further includes an evaporation gas collecting unit installed at an upper part of the inside of the housing to collect evaporation gas.

The invention relates to an air cleaner housing for a vehicle, comprising an outer and an inner circumferential wall, and a space therebetween adapted to house at least one filter element for filtering air, wherein the inner circumferential wall is provided with openings to allow filtered air to pass radially inwardly through the inner circumferential wall. The air cleaner housing comprises a first end and an open second end for fluidly connecting the air cleaner housing to a turbo, the open second end being located opposite the first end. The air cleaner housing comprises a resonator, wherein the entire resonator is encircled by the inner circumferential wall such that air entering through the inner circumferential wall passes on the outside of the resonator to and through the open second end.
