Air filter housing with closing arrangement, air filter, and vehicle

1. An air filter housing for use in an air cleaning arrangement for cleaning air to be provided to an air inlet of an internal combustion engine, the air filter housing comprising:

a filter housing inlet for receiving air; and

a filter housing outlet for providing filtered air to the air inlet of the internal combustion engine when an air filter is arranged inside the air filter housing between the filter housing inlet and the filter housing outlet; and

a closing arrangement comprising an iris shutter controllable to be in each of a first state in which the filter housing outlet is closed by the closing arrangement, and a second state in which the filter housing outlet is open, the closing arrangement comprising:

an electric motor connected to the iris shutter and controllable to open and close the iris shutter;

a filter sensing module configured to:

sense a presence of a correctly installed air filter having a filter identification and communication module embedded in an end portion of the air filter to communicate with the filter sensing module in the air filter housing;

when the air filter has been installed, attempt to establish a connection with the filter identification and communication module in the air filter; and

interrogate, if the connection can be established, the filter identification and communication module; and

a control unit, configured to control, if the filter sensing module can establish, based on the interrogation, that the air filter is of the correct type, the electric motor to open the iris shutter.

2. The air filter housing of claim 1 , wherein:

the air filter housing further comprises a filter removal detector configured to detect initiation of filter removal; and

the closing arrangement is connected to the filter removal detector and configured to close the filter housing outlet, when the filter removal detector detects the initiation of filter removal.

3. The air filter housing of claim 1 , wherein the air filter housing further comprises a guiding structure for guiding the air filter towards an intended air filter position.

4. The air filter housing of claim 1 , wherein the filter sensing module is configured to:

check that the air filter is still correctly arranged; and

provide, if the air filter is not correctly arranged and the internal combustion engine is running, a signal indicating displacement of the air filter.

5. The air filter housing of claim 4 , wherein the signal indicating displacement of the air filter is provided to an engine control unit.

6. The air filter housing of claim 1 , wherein:

the filter sensing module is configured to check that the air filter is still correctly arranged; and

the control unit is configured to control the electric motor to close the iris shutter when it is determined that the air filter has been displaced and the internal combustion engine is not running.

7. An air cleaning arrangement for cleaning air to be provided to an air inlet of an internal combustion engine, comprising:

an air filter comprising:

filter material allowing passage through the filter material of air, and preventing passage through the filter material of particles suspended in air; and

a filter identification and communication module embedded in an end portion of the air filter;

an air filter housing comprising:

a filter housing inlet for receiving air; and

a filter housing outlet for providing filtered air to the air inlet of the internal combustion engine when the air filter is arranged inside the air filter housing between the filter housing inlet and the filter housing outlet; and

a closing arrangement comprising an iris shutter controllable to be in each of a first state in which the filter housing outlet is closed by the closing arrangement, and a second state in which the filter housing outlet is open, the closing arrangement comprising:

an electric motor connected to the iris shutter and controllable to open and close the iris shutter;

a filter sensing module configured to:

sense a presence of the air filter when it is correctly installed;

attempt to establish a connection with the filter identification and communication module in the air filter; and

interrogate, if the connection can be established, the filter identification and communication module; and

a control unit, configured to control, if the filter sensing module can establish, based on the interrogation, that the air filter is of the correct type, the electric motor to open the iris shutter.

8. An internal combustion engine having an air inlet, the internal combustion engine comprising

the air cleaning arrangement of claim 7 configured to provide filtered air to the air inlet of the internal combustion engine.

9. A vehicle comprising:

a vehicle body;

at least one wheel rotatably connected to the vehicle body; and

the internal combustion engine of claim 8 configured to drive the at least one wheel.
