Abstract

A system is provided for performing a cleaning process of a component of a vehicle. The system includes a first cleaning applicator configured to deliver a cleaning agent to a first surface of the component of the vehicle, a second cleaning applicator configured to deliver the cleaning agent to a second surface of the component of the vehicle, a third cleaning applicator configured to deliver the cleaning agent to a third surface of the component of the vehicle, and a control unit configured to instruct each of the first, second, and third cleaning applicators to project the cleaning agent onto the respective surface of the component for a corresponding predetermined period. The first, second, and third applicators are instructed to project the cleaning agent in a predetermined sequence.

First claim

What is claimed is:

1. A cleaning system for performing a cleaning process of a component of a vehicle, comprising:
a viewing device to capture one or more images of the component of the vehicle;
an actuator to selectively move the component of the vehicle in one or more directions;
a first cleaning applicator configured to deliver a cleaning agent to a first surface of the component of the vehicle;
a second cleaning applicator configured to deliver the cleaning agent to a second surface of the component of the vehicle;
a third cleaning applicator configured to deliver the cleaning agent to a third surface of the component of the vehicle; and
a control unit configured to instruct the first cleaning applicator to project the cleaning agent onto the first surface of the component for a first predetermined period, the second cleaning applicator to project the cleaning agent onto the second surface of the component for a second predetermined period, and the third cleaning applicator to project the cleaning agent onto the third surface of the component for a third predetermined period, the first, second, and third applicators being instructed to project the cleaning agent in a predetermined sequence,
wherein the viewing device is communicably coupled to the control unit and configured to receive the one or more images of the component of the vehicle, and
wherein the control unit is configured to control the viewing device and the actuator during the cleaning process by rotating the actuator in a desired direction to clean outer surfaces of the component.

2. The cleaning system of claim 1 , wherein the cleaning agent is air, carbon dioxide, or alcohol.

3. The cleaning system of claim 1 , wherein each of the first surface, the second surface, and the third surface corresponds to any one of: a side surface, an upper surface, a lower surface, an internal surface, or a passageway of the component.

4. The cleaning system of claim 1 , wherein the component is any one of: a valve seat, a tappet, a plunger, or an injector needle of a fuel injector in the vehicle.

5. The cleaning system of claim 1 , the control unit further comprising a pump configured to deliver the cleaning agent to the first, second, and third cleaning applicators.

6. The cleaning system of claim 5 , wherein the pump is configured to deliver the cleaning agent at a pressure of above 5 MPa, 10 MPa, 20 MPa, or 50 MPa.

7. The cleaning system of claim 5 , wherein the pump is configured to deliver the cleaning agent at a temperature of above 70° C., 100° C., 150° C., or 200° C.

8. The cleaning system of claim 5 , wherein the cleaning agent includes air, alcohol, or carbon dioxide, and the control unit is configured to select whether the air, the alcohol, or the carbon dioxide is to be delivered by the pump.

9. The cleaning system of claim 8 , wherein the carbon dioxide is liquid carbon dioxide which may transform into dry ice snow or crystals when delivered to any one of the first, second, and third surfaces of the component.

10. The cleaning system of claim 1 , wherein the control unit is configured to control the viewing device and the actuator by selectively moving the viewing device to detect the presence of unwanted particles or contaminants and to detect a wet condition or a dry condition of the component of the vehicle.

11. A method for performing a cleaning process of a component of a vehicle, comprising:
capturing, with a viewing device, one or more images of the component of the vehicle;
selectively moving the component of the vehicle in one or more directions with an actuator;
delivering a cleaning agent to a first surface of the component of the vehicle using a first cleaning applicator;
delivering the cleaning agent to a second surface of the component of the vehicle using a second cleaning applicator;
delivering the cleaning agent to a third surface of the component of the vehicle using a third cleaning applicator; and
instructing, via a control unit, the first cleaning applicator to project the cleaning agent onto the first surface of the component for a first predetermined period, the second cleaning applicator to project the cleaning agent onto the second surface of the component for a second predetermined period, and the third cleaning applicator to project the cleaning agent onto the third surface of the component for a third predetermined period, and further instructing the first, second, and third applicators to project the cleaning agent in a predetermined sequence,
wherein the viewing device is communicably coupled to the control unit and configured to receive the one or more images of the component of the vehicle, and
wherein the control unit is configured to control the viewing device and the actuator during the cleaning process by rotating the actuator in a desired direction to clean outer surfaces of the component.

12. The method of claim 11 , wherein each of the first surface, the second surface, and the third surface corresponds to any one of: a side surface, an upper surface, a lower surface, an internal surface, or a passageway of the component.

13. The method of claim 11 , wherein the component is any one of: a valve seat, a tappet, a plunger, or an injector needle of a fuel injector in the vehicle.

14. The method of claim 11 , further comprising: delivering, by a pump operatively coupled to the control unit, the cleaning agent to the first, second, and third cleaning applicators.

15. The method of claim 14 , wherein the cleaning agent includes air, alcohol, and carbon dioxide, the method further comprising: selecting, by the control unit, whether the air, the alcohol, or the carbon dioxide is to be delivered by the pump.

16. The method of claim 15 , wherein the carbon dioxide is liquid carbon dioxide which may transform into dry ice snow or crystals when delivered to any one of the first, second, and third surfaces of the component.
