摘要:
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.

An air filter group for air supply to internal combustion engines of motor vehicles, of a type comprising an external casing provided with an inlet opening of the air to be filtered, and an outlet opening of the filtered air, and a removable cover, the inlet and outlet openings being separated by a removable filter cartridge which comprises a hollow cylindrical filter wall crossed by the air in a centripetal direction, in which the at least a filter cartridge is fixed to the cover in which cover a chamber is present, delimited by a base provided with at least a hole at which the at least a cartridge is fixed, by an opposite wall to the base and by an annular wall located between the base and the opposite wall and comprising the outlet hole of the filtered air, the cover being destined to be inserted sealedly in the casing.
摘要:
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.

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.
摘要:
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.
摘要:
A filter housing (10) for a filter unit (50) with a substantially semicylindrical air filter (52). The housing includes an air inlet (20) and an engine air outlet (40). The filter housing (10) has a top aperture (12) for introducing and taking out the filter unit (50), and a cover (30) to close the top aperture (12), a bottom aperture (16) to be closed and opened by a closed filter bottom (70) of the filter unit (50) being introduced or taken out. Also, a filter unit for such a filter housing is disclosed.
摘要:
An agricultural vehicle air cleaner assembly having at least one cyclonic generator to enable the removal of suspended particles from an airflow through the air cleaner assembly. The cyclonic generator has at least one vane which acts to generate a cyclone downstream of the generator, where the pitch of the vane is adjustable. By adjusting the pitch of the vane, the cyclones generated by the air cleaner assembly for a given airflow can be adjusted, thereby allowing for dynamic adjustment of the particle removal effect of the air cleaner assembly.
摘要:
An air filter device for a motor vehicle is provided with a filter housing having an air inlet and an air outlet, a filter insert which is received in the filter housing and divides the inside of the filter housing into an untreated air section and a pure air section, and a bypass line for supplying air into the untreated air section. The bypass line extends from a connection opening in the filter housing to a cooler, especially a charge air cooler of the motor vehicle.
摘要:
An air filter arrangement has a filter housing (10) for connection to a duct (80) for a combustion engine. The filter housing (10) has a cover (30) for closing a top aperture of the filter housing (10). An engine air outlet (40) is on the cover (30). A flexible pipe section (42) on the engine air outlet and for connection to the duct, the flexibility to allow the cover (30) to be removed from the top aperture and a filter unit to be introduced into or taken out from the filter housing (10).
