The invention relates to a filter element unit for an air filter of a vehicle with an internal combustion engine, including: a filter element, a filter medium; and a one-piece gasket. The gasket includes: a first part circumferentially surrounding the filter element and adapted to seal the filter element against a first channel of a filter housing of the air filter and a second part formed unitary with the first part and spaced away from the first part and spaced away from the filter medium, the second part is adapted to seal a second channel of the filter housing; wherein the first part and the second part are connected with each other via at least two bridges.

An air intake assembly configured to direct air into a throttle body of an engine of an automotive vehicle includes an air cleaner enclosure, primary and secondary air intake ducts, a ram air power valve and a downstream air intake duct. The air cleaner enclosure unit has an air cleaner inlet and an air cleaner outlet. The primary air intake duct directs air between a primary air inlet and the air cleaner inlet. The secondary air intake duct directs air between a secondary air inlet and the air cleaner inlet. The ram air power valve is disposed in the secondary air intake duct and is configured to move between an open position and a closed position. In the open position, air is permitted to flow through the secondary intake duct. In the closed position air is inhibited from passing through the secondary air intake duct.

A system for capturing cleaner intake air for use within an air intake system of a work vehicle may generally include an intake duct defining an inlet for receiving air and at least one actuator associated with the intake duct. The actuator(s) may be configured to move at least a portion of the intake duct so as to adjust a position of the inlet relative to a fixed reference location on the work vehicle. In addition, the system may include at least one sensor configured to monitor an air-related parameter associated with the work vehicle and a controller communicatively coupled to the actuator(s) and the sensor(s). The controller may be configured to actively control the operation of the actuator(s) such that the position of the inlet is adjusted based on the air-related parameter so as to reduce an amount of particulates received within the intake duct.

An air cleaner has 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 looped wall, which protrudes from the inner surface thereof, and a vibrating body, which is made of a non-air permeable material and fixed to the upper end of the looped wall. Inside the first housing, an air chamber is defined by the inner surface of the bottom wall, the inner peripheral surface of the looped wall, and the lower surface of the vibrating body.

A pre-filter assembly for a vehicle arranged with an aspiration duct extending between the pre-filter and a fan of the vehicle. A variable valve element is provided as part of the aspiration duct adjacent the fan, such that the aspiration rate through the duct can be controlled by appropriate variation of the valve element, to control the rate of airflow drawn through the aspiration duct by the fan. This allows for the aspiration rate of the pre-filter to be at least partly independent of the flow rate of the fan, without the need for an additional motor-driven blower unit.

An air intake system includes a pre-cleaner having a plurality of tubes configured to receive a flow of air, to filter particulate material from the flow of air, and to provide the flow of air to an engine of an off-road vehicle. The system also includes a controller configured to receive a first signal indicative of an air intake flow rate of the engine, to determine a target number of open tubes for the pre-cleaner based at least in part on the air intake flow rate and a desired air flow rate for each tube of the plurality of tubes, and to output a second signal to a component of the air intake system indicative of instructions to enable the flow of air to the target number of open tubes and to block the flow of air to the remainder of tubes of the plurality of tubes.

An airbox includes an intake air inlet in a housing, wherein the intake air inlet includes a first portion and a second portion, at least one air outlet in the housing, and an air chamber within the housing and fluidly connected to the intake air inlet and the at least one air outlet. The air chamber includes an internal wall that divides the air chamber along an axis thereof into a first air chamber portion fluidly connected to the first portion of the air inlet and a second air chamber portion fluidly connected to the second portion of the air inlet, and a moveable air inlet damper configured to seal the first portion of the air inlet and occlude the first air chamber portion, or to seal the second portion of the air inlet and occlude the second air chamber portion.

A vehicle system, includes an air intake assembly, a heat source, a valve, a temperature indicator and a controller. The air intake assembly including an inlet through which air flows, a filter downstream of the inlet, and an outlet downstream of the filter through which air from the filter flows. The valve is electrically actuated and arranged to selectively permit air flow from the heat source to the inlet. The temperature indicator provides an indication of a temperature in the air intake assembly upstream of the filter. And the controller is communicated with the temperature indicator and the valve and operable to open the valve when the output of the temperature indicator indicates a temperature below a temperature threshold.

An electrically-assisted turbocharger includes an electrically-assisted turbocharger body. A side of the electrically-assisted turbocharger body is connected to a docking pipe, a side of the docking pipe is connected to a sealing cover, a bottom of the sealing cover is fixed with a purification pipe, two ends of the purification pipe are closed, a side of the purification pipe is connected to an air intake pipe, and an inside of the purification pipe is provided with an intermittent driving element. Multiple through-holes penetrating into an inside of the sealing cover are equidistantly defined on a top surface of the inside of the purification pipe, and a filtering assembly is slidably connected to an inside of each of the multiple through-holes. The electrically-assisted turbocharger solves a problem of dust accumulation on a filter element affecting its permeability in a turbocharger in the related art.
