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.

The present invention relates to a hood (40) of a multi cyclone block (12) and an air cleaner (10). The cyclone block (12) has a plurality of cyclone cells (28). The hood (40) having at least one hood-inlet (50) and at least one hood-outlet (52) for air to be fed to the cyclone cells (28). The at least one hood-outlet (52) is designed for surrounding, a plurality of cell-inlets (36) of the cyclone cells (28) of the cyclone block (12). A wall (70) of the hood (40) defines a distributor volume (72) inside the hood (40), which is located between the at least one hood-inlet (50) and the at least one hood-outlet (52). The wall (70) has at least one line or area of inflection (74), where at least one inner surface of the wall (70) changes its curvature.

The utility vehicle includes a body; a frame that supports the body; an on-board device that is mounted on the frame and requires outside air; and an air intake conduit that is connected to the on-board device. An air intake port of the air intake conduit that sucks in outside air faces a center side of the utility vehicle.

An air intake system may include an engine air cleaner having a dust valve. The intake system may be configured for arrangement on the engine. The dust valve may also be operable to open or close based on operating characteristics of the engine.

An air intake assembly has an inlet member, a fluid reservoir, and an outlet. The inlet member defines a generally vertical oriented first fluid channel. The first fluid channel has a vertically extending portion, an upper inlet end, and a lower end. The fluid reservoir has an upper region that defines a second fluid channel. The fluid reservoir is attached to a lower end of the inlet member such that the first fluid channel vertically extending portion is substantially perpendicular to the second fluid channel. The fluid reservoir has an outlet defined by an aperture in a lower region of the fluid reservoir which forms a liquid collector. The trapdoor is pivotably attached to the fluid reservoir adjacent to the outlet. The rigid trapdoor is configured to open when exposed to a predetermined open force value to allow liquid to escape the liquid collector.

Provided is a construction machine capable of collecting foreign matter into a dust collection pocket and preventing the foreign matter from being scattered. The construction machine includes a cooler, an air passage forming member including a curved section, a dust-proof filter, a cooling fan generating a normal wind for cooling and a reverse wind opposite thereto, a dust collection pocket, and a turning member. The dust collection pocket has an opening and collects foreign matter at a position downstream of the inner wall surface of the outer corner of the curved section. The turning member is turned about a turning axis by the normal wind and the reverse wind, thereby being moved between a close position to close the opening and an open position to open the opening.

An air intake system may include an engine air cleaner having a dust valve. The intake system may be configured for arrangement on the engine. The dust valve may also be operable to open or close based on operating characteristics of the engine.

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.

The utility vehicle includes a body; a frame that supports the body; an on-board device that is mounted on the frame and requires outside air; and an air intake conduit that is connected to the on-board device. An air intake port of the air intake conduit that sucks in outside air faces a center side of the utility vehicle.

An air cleaner assembly for filtering intake air for a power plant can include a filter cartridge disposed within a housing of the air cleaner assembly, a precleaner assembly including at least one particle separator for separating particulates from an airflow stream and a scavenge port for discharging the separated particulates, the precleaner assembly being located upstream of the filter cartridge, a scavenge system for evacuating the separated particulates out of the scavenge port, the scavenge system including an electric motor coupled to an fan, an input sensor generating an input signal relating to a parameter associated with one or more of the precleaner assembly, the air cleaner assembly, a power plant receiving air from the air cleaner assembly, and a vehicle associated with the power plant, and a controller for operating the speed of the scavenge system based on the input signal from the input sensor.
