A hose clamp includes an open ended ring body having a first engagement pin located at one end portion, a second engagement pin located at another end portion, and a retaining clip located adjacent the first engagement pin; and a connecting lever detachably attached to the ring body, and including a lever body having a first pivot notch located on one end, a second pivot notch spaced away from the first pivot notch, and a clipping slot located at another end. The first notch of the lever is connected to the first engagement pin of the ring, and the second notch is connected to the second engagement pin of the ring. When the lever is rotated relative to the ring body, the first notch pivots around the first engagement pin and the second notch of the lever pulls the second engagement pin around the first engagement pin.

Systems and methods are disclosed for an air intake assembly comprising an airbox defining a plenum for enclosing an air filter, an intake tube attached to the air filter at a first end of the intake tube, the intake tube having a shoulder, and a multi-lipped gasket for detachably connecting the intake tube to the airbox, the multi-lipped gasket comprising a body portion defining a bore for sealingly engaging the intake tube, a lip adjacent the bore for engaging the shoulder of the intake tube, and a pair of distal lips for sealingly engaging the airbox, wherein the airbox, the air filter, and the intake tube are adapted so that air flows into the airbox, through the air filter, through the intake tube, and into a combustion engine (optionally reaching the combustion engine by first passing through a turbocharger and intercooler) of a vehicle.

There is provided an air cleaner configured to be disposed inside a vehicle body frame, the air cleaner including: an air cleaner case in which an intake chamber is formed; an air filter disposed in the intake chamber; an inlet tube configured to take in air to the intake chamber; and an outlet tube configured to send out the air from the intake chamber. The inlet tube extends in a front-rear direction. The inlet tube has a bottom wall curved downward in a side view to form a concave curved portion below a discharge port of the inlet tube. The concave curved portion is formed with a drain hole.

An intake assembly for an internal-combustion engine includes an intake duct for each cylinder, which communicates with an airbox that includes a filtering element. Each intake duct communicates with the airbox by a respective throttle body. A monitoring channel connects the intake ducts together and is configured for perturbing in a negligible way the dynamics of the fluid inside the intake ducts. Associated to said monitoring duct are sensors for monitoring the pressure inside the monitoring duct and designed to send signals indicating the value of pressure of the fluid taken in by the engine to an electronic control unit.

A filter housing has a first housing part with a first rim section and a second housing part with a second rim section. The housing parts can be joined and separated from each other in axial mounting direction and define a housing interior for a filter element provided with a circumferentially extending sealing element. The first and second rim sections form a receiving area in which the sealing element is seal-tightly clamped radially between the first and second rim sections when the housing parts are joined in the mounted state. A snap connecting device axially braces the first and second housing parts relative to each other. The snap connecting device is formed integrally on the first and second housing parts such that a clamping force applied by the first and second rim sections on the sealing element in radial direction is decoupled from the snap connecting device.

A filtration device may include an adapter, a filter element, and a housing. The adapter may include a collar having an upper rim and a lower rim, a plurality of locking tabs extending from the upper rim, and a plurality of snap members extending from the lower rim. The filter element may include a casing and a plurality of receptacles connected to and arranged around a first outer surface of the casing. The plurality of receptacles are configured to receive the plurality of locking tabs. The housing, which is configured to receive the filter element, includes a shell and a plurality of ramp members that are connected to a second outer surface of the shell. The plurality of ramp members are configure to engage the plurality of snap members.

An air cleaner assembly including a tray including a cleat receptacle at a back side of the assembly and a cover including a cleat at the back side. The assembly further includes guide features arranged at a front side of the assembly. The guide feature are designed to contact one another continuously and guide the cover rearward, from an unseated position to a fully seated position where the cleat is seated within the cleat receptacle.

An air filter (10) includes an openable filter housing (12) and a filter element (18). The filter housing (12) includes an inlet (26) and an outlet. A filter element (18) with a filter medium (46) is disposed replaceably in the filter housing separating the inlet (26) from the outlet (22). The filter element (18) features on an exterior side facing away from the element interior space (52) on an axial front face relative to the element axis (32) at least one supporting element (58) having at least one supporting lateral surface (60, 61) with at least one cylindrical portion and/or at least one portion with a variable cross-section in the direction of a main axis. The supporting element (58) is supported at least transversely in relation to the element axis (32) with the at least one supporting lateral surface (60, 61) against at least one corresponding support portion (42) on the side of the filter housing (12).

A filter cartridge arrangement is provided which includes a media pack comprising Z-filter media, a preform and a housing seal member. Improvements in the preform and seal member are described which include: a single beveled surface of the seal member to facilitate installation; and, an inside region of the seal member having a tip adjacent in inwardly directed lip of the preform, to control flash during molding. A variety of media pack configurations and features are described.
