A cowling for an outboard motor has port and starboard intake ports that direct flow of intake air into the cowling and extend downwardly along the aftward side of the cowling and face laterally outwardly. A duct system receives and conveys intake air intake ports to an intake conduit for the outboard motor. The duct system includes port and starboard intake troughs that extend alongside the intake ports and redirect the intake air from a generally lateral flow into the intake ports to a generally vertically downward flow and then to a generally forward flow towards the intake conduit. Port and starboard baffles that extend alongside the intake ports and direct flow of water into port and starboard channels located alongside the baffles, respectively. The channels drain the water by gravity depending on tilt and trim orientation of the outboard motor.

An air intake system for a commercial vehicle is disclosed. The air intake system includes a hood with at least one frontal intake opening through which air to be guided to an engine of the commercial vehicle can flow and with at least one plenum configured to receive air flowing through the intake opening. The air intake system further includes at least one air pipe having at least one air duct with at least one inlet opening through which the air flowing through the frontal intake opening can flow, the air duct arranged upstream of and fluidically connected with the plenum so as to guide the air to and into the plenum. The air intake system additionally includes at least one air filter and at least one silencer plate arranged upstream of the air filter, the silencer plate having a plurality of through openings through which the air can flow.

An intake system component of an internal combustion engine includes a porous material product and a resin molded portion. The porous material product is formed from a porous material and includes an outer edge and a general portion. The resin molded portion encompasses the outer edge and is formed integrally with the porous material product. The general portion is located outside the resin molded portion. The outer edge has a lower filling density than the general portion.

The invention relates to a filter element for mounting in an air cleaner housing of a vehicle. The filter element comprises a circumferential filtering wall through which air is allowed to enter. The filter element also comprises a first end and an open second end for fluidly connecting the filter element to a turbo. The open second end is located opposite the first end. The circumferential filtering wall extends from the first end towards the open second end. The filter element further comprises a resonator. The entire resonator is encircled by the circumferential filtering wall such that air entering through the circumferential filtering wall passes on the outside of the resonator to and through the open second end.

A pipe unit coupling structure includes a first member in which a first hole is formed, a second member including a pipe unit which is coupled to the first member by being inserted into the first hole, and a third member coupled to the second member by a coupling unit. The second member has an inclined surface formed at a tip of the pipe unit. The inclined surface is configured in such a manner that, when the inclined surface is pressed against the first member when the pipe unit of the second member is inserted into the first hole of the first member in a state where the second member and the third member are coupled to each other, a force is applied from the second member to the third member at the coupling unit, in a direction opposite to a direction of separation of the second member.

A vehicle air filter housing having a broad band tuner. The housing is formed from a tray having a divider wall defining an unfiltered air induction chamber and a tuner chamber. A cover securable to the tray includes a second divider wall defining a filtered air chamber and a flow path chamber. A filter member provides a seal between the tray and the cover, and holds an air filter between the unfiltered air chamber and the filtered air chamber. A plate securable to the flow path chamber has a plurality of perforations. Air inducted through the inlet passes through the air filter and flows through the flow path chamber at a velocity whereby the filtered air passes over the perforated plate and predetermined frequencies pass through the plate perforations for attenuation in the tuner chamber. The tuners in the tuner chamber may be sized to attenuate different frequencies.
