Abstract

A system for treating ambient air is provided. The system includes a flow control structure disposed on a vehicle. The flow control structure is adapted to control flow of ambient air received during movement of the vehicle. The system further includes an actuator operatively coupled to the flow control structure. The actuator is adapted to movably adjust the flow control structure. The system further includes a controller disposed on the vehicle and communicably coupled to the actuator. The controller is configured to control the actuator based on at least a quality of ambient air. The system further includes an air treatment component for selectively receiving ambient air from the flow control structure. The air treatment component is adapted to treat at least one pollutant present in ambient air.

First claim

What is claimed is:

1. A system for treating ambient air, the system comprising:
a flow control structure disposed on a vehicle, the flow control structure adapted to control flow of ambient air received during movement of the vehicle;
an actuator operatively coupled to the flow control structure, the actuator adapted to movably adjust the flow control structure;
a controller disposed on the vehicle and communicably coupled to the actuator, the controller configured to control the actuator based on at least a quality of ambient air and based on one of a temperature of an engine of the vehicle, a vehicle performance, or a location of the vehicle; and
an air treatment component for selectively receiving ambient air from the flow control structure, the air treatment component adapted to treat at least one pollutant present in ambient air.

2. The system of claim 1 , further comprising a sensor configured to generate signals indicative of a quality of ambient air, wherein the controller is further configured to receive the signals from the sensor.

3. The system of claim 2 , wherein the sensor is disposed on the vehicle.

4. The system of claim 1 , wherein the controller is communicably coupled to a database, wherein the controller is further configured to receive data indicative of the quality of ambient air from the database.

5. The system of claim 1 , wherein the flow control structure is further adapted to selectively block flow of ambient air to the air treatment component.

6. The system of claim 1 , wherein the flow control structure includes at least one of a front grill, a spoiler, a fin, a blade, a vane and a valve.

7. The system of claim 1 , wherein the air treatment component includes at least one of a catalytically active surface and a particulate filter.

8. The system of claim 1 , further comprising an outlet for discharging treated ambient air received from the air treatment component to atmosphere, wherein the outlet is disposed on the vehicle.

9. The system of claim 1 , further comprising a rain sensor communicably coupled to the controller, wherein the controller is further configured to control the actuator based on signals received from the rain sensor.

10. A method for treating ambient air, the method comprising:
receiving flow of ambient air at a flow control structure during movement of a vehicle, wherein the flow control structure is disposed on the vehicle;
movably adjusting, based on at least a quality of ambient air and one of a temperature of an engine of the vehicle or a vehicle performance, the flow control structure to control flow of ambient air;
treating, by an air treatment component, at least one pollutant present in ambient air received from the flow control structure; and
discharging treated ambient air to atmosphere.

11. The method of claim 10 , further comprising determining the quality of ambient air based on signals received from a sensor.

12. The method of claim 10 , further comprising receiving data indicative of the quality of ambient air from a database.

13. The method of claim 10 , wherein movably adjusting the flow control structure further comprises selectively blocking flow of ambient air to the air treatment component.

14. The method of claim 10 , wherein the flow control structure is movably adjusted further based on signals received from a rain sensor.

15. A system for treating ambient air, the system comprising:
a flow control structure disposed on a vehicle, the flow control structure adapted to control flow of ambient air received during movement of the vehicle;
an actuator operatively coupled to the flow control structure, the actuator adapted to movably adjust the flow control structure;
a controller disposed on the vehicle and communicably coupled to the actuator, the controller configured to control the actuator based on at least a quality of ambient air;
an air treatment component for selectively receiving ambient air from the flow control structure, the air treatment component adapted to treat at least one pollutant present in ambient air; and
a rain sensor communicably coupled to the controller, wherein the controller is further configured to control the actuator based on signals received from the rain sensor.

16. The system of claim 15 , further comprising a sensor configured to generate signals indicative of a quality of ambient air, wherein the controller is further configured to receive the signals from the sensor.

17. The system of claim 16 , wherein the sensor is disposed on the vehicle.

18. The system of claim 15 , wherein the controller is communicably coupled to a database, wherein the controller is further configured to receive data indicative of the quality of ambient air from the database.

19. The system of claim 15 , wherein the flow control structure is further adapted to selectively block flow of ambient air to the air treatment component.
