A siloxane mitigation system for a machine system having an internal combustion engine includes a siloxane trap having a plurality of adsorbent cartridges fluidly in parallel with one another, an air precleaner fluidly connected to a trap housing inlet, and a blower structured to blow intake air to the siloxane trap to compensate for a pressure drop across the siloxane trap. A trap performance sensor of the siloxane mitigation system is structured for monitoring an exhaust pressure to indicate performance degradation of the siloxane mitigation system and activate an operator-perceptible alert.

An air-intake device comprises a vehicle body frame including a head box; and a pair of right and left main frames, wherein the head box includes: a casing section which extends between a front opening and a rear opening of the head box and is formed with a main air passage; and a pair of right and left extending sections coupled to the pair of main frames, respectively, wherein at least one extending section is provided with a branch air passage which branches from the main air passage, and wherein a separating wall is provided between the main air passage and the branch air passage and has a communication hole, and wherein when a vehicle body is viewed from a side, at least one extending section is extended rearward to a location at which at least a front region of the communication hole is covered by the extending section.

An all-terrain vehicle includes a frame; two seats arranged on the frame; a container arranged on the frame and located at a rear side of the seat, a top of the container being open; a power system arranged on the frame; an air filter coupled to the power system, arranged on the frame and located below the container; and a storage box arranged on the frame and located behind the two seats, the storage box being detachably coupled to the frame, the air filter and/or the power system being repairable after the storage box being removed.

An apparatus and method for a heat shield with an integrated air filter assembly is disclosed. Wherein the air filter assembly comprising a filter material circumferentially extending such that the filter material surrounds at least a portion of an interior cavity of the air filter, a distal end cap affixed to a distal end of the filter material, and a wire support extending along at least a portion of an exterior surface of the filter material; and wherein the heat shield is configured to direct cooler air into an air intake conduit extending from an intake portion of an automobile engine for combustion.

There is provided a straddle-type vehicle, including: a pair of seat frames; a seat; an air cleaner; a battery; and a bracket. A rear portion of the air cleaner and the battery are positioned below the seat. The battery is disposed above the rear portion of the air cleaner. The bracket extends in a left-right direction of the straddle-type vehicle and passes between the rear portion of the air cleaner and the battery. A left end side and a right end side of the bracket are connected to the pair of seat frames respectively. The rear portion of the air cleaner is suspended by the bracket. The battery is installed on the bracket.

The Multiple Intake Air Filtration Device of this invention is a superior, highly efficient air cleaner that utilizes an array of multiple-intake cyclonic tubes spinning air at high speed to efficiently remove the specific sizes of dirt and other particulates that can be ingested in off-road and highway vehicle operations. This Multiple Intake Air Filtration Device is well-suited for use with both normally-aspirated engines and turbocharged engines. It is superior to automotive air cleaners that filter out dirt by use of a screen or porous media because it never becomes clogged as dirt and particulates are filtered out, and it is superior to devices that utilize only a single air flow through cyclonic tubes, because the device of this invention cleans intake air more efficiently while providing a strong flow of clean air to the engine or other component.

Vehicle Engine Air Intake System and Method (to be accompanied by FIGS. 1 and 3) In a motor vehicle (12), an air filter housing (14) is at least partially defined by a cross-member (28) forming part of a structural front end module of the vehicle body. The cross-member (28) defines a recess (44) for receiving an air filter (90) and at least one air inlet aperture opening into the recess. An air filter enclosure assembly is mounted to the cross-member over an open face of the recess. The air filter enclosure assembly may include an air filter enclosure (42) and an air filter (90).

There is provided an air cleaner configured to be disposed behind an engine and inside a vehicle body frame. The air cleaner includes: an air cleaner case in which an intake chamber is formed; an air filter that divides the intake chamber into a dirty side and a clean side; an inlet tube configured to take in air from a vehicle rear side to the dirty side; and an outlet tube configured to send air from the clean side to the engine. The inlet tube and the outlet tube are attached to an upper side of the air cleaner case, and an expansion portion is formed on a lower side of the air cleaner case, the expansion portion being formed by expanding the clean side further downward than the dirty side.

A vehicle air induction assembly includes an air guide, an air duct and a bracket member. The air duct is configured to supply air to an engine air filter. The air guide has an opening therein and is configured to be connected to a vehicle fascia. The air duct is configured to be connected to the air guide such that air flowing through the opening flows into the air duct. The bracket member is connected to the air guide. The bracket member has a first side wall, a second side wall and a lower wall connecting the first and second side walls. The bracket member and the air duct are disposed on opposite sides of the air guide opening. An air inlet is defined by the air guide and the bracket member.

An apparatus and method for a heat shield with an integrated air filter assembly is disclosed. Wherein the air filter assembly comprising a filter material circumferentially extending such that the filter material surrounds at least a portion of an interior cavity of the air filter, a distal end cap affixed to a distal end of the filter material, and a wire support extending along at least a portion of an exterior surface of the filter material; and wherein the heat shield is configured to direct cooler air into an air intake conduit extending from an intake portion of an automobile engine for combustion.
