System and method of controlling an amount of condensation in an engine air intake system

1. A condensation collection system for an internal combustion engine having an exhaust gas recirculation system, the condensation collection system comprising:

a condensation accumulator having an input port and an output port;

a condensation collection line having a condensation collection inlet and a condensation collection outlet, the condensation collection inlet being coupled to an air intake system of an internal combustion engine, the condensation collection outlet being coupled to the input port of the condensation accumulator;

a condensation expulsion line coupled to the output port of the condensation accumulator, a portion of the condensation expulsion line being disposed in contact with an engine exhaust pipe, the condensation expulsion line having an outlet provided to expel condensation from the system; and

a condensation control valve moveable between an open position and a closed position, the condensation control valve being disposed within the air intake system and being configured to control condensation flow to the condensation collection line.

2. The condensation collection system of claim 1 further comprising a fluid level sensor disposed in the condensation accumulator.

3. The condensation collection system of claim 1 further comprising a filter disposed in the condensation collection line.

4. The condensation collection system of claim 1 further comprising a filter disposed in the condensation expulsion line.

5. The condensation collection system of claim 1 , wherein at least a portion of the condensation expulsion line in contact with the engine exhaust pipe traverses a perimeter of the engine exhaust pipe.

6. The condensation collection system of claim 1 further comprising a condensation sensor disposed in the air intake system, the condensation sensor being configured to generate an output signal indicative of a level of condensation within the air intake system.

7. The condensation collection system of claim 6 , wherein the condensation sensor is configured to set the condensation control valve between the open position and the closed position.

8. A method of removing condensation from an air intake system of an internal combustion engine having an exhaust gas recirculation system, the method comprising:

transferring condensation from the air intake system to a condensation accumulator through a condensation collection line, the condensation collection line being disposed in fluid communication with the air intake system and the condensation accumulator;

collecting a predetermined amount of condensation within the condensation accumulator;

expelling condensation from the condensation accumulator through a condensation expulsion line coupled to the condensation accumulator; and

heating the condensation within the condensation expulsion line to form vapor within the condensation expulsion line prior to expelling the condensation to the atmosphere.

9. The method of claim 8 further comprising:

monitoring a level of condensation within the air intake system with a condensation sensor; and

opening a condensation control valve when the condensation within the air intake system is above a predetermined value, the condensation control valve controlling fluid communication between the condensation collection line and the air intake system.

10. The method of claim 9 , wherein the heating of the condensation within the condensation expulsion line is performed by an exhaust pipe.

11. The method of claim 10 , wherein a portion of the condensation expulsion line is traverses at least a portion of a perimeter of the exhaust pipe.

12. The method of claim 8 further comprising filtering the condensation within the condensation collection line prior to collecting the condensation in the condensation accumulator.

13. The method of claim 8 further comprising filtering the condensation within the condensation expulsion line prior to expelling the condensation.

14. The method of claim 13 , wherein the filtering removes particulate matter from the condensation.

15. An internal combustion engine comprising:

an air intake system;

an exhaust system having an exhaust gas recirculation system, and an exhaust pipe, the exhaust gas recirculation system being in fluid communication with the air intake system;

a condensation sensor being disposed within the air intake system;

a condensation accumulator having an input port and an output port;

a condensation collection line having a condensation collection inlet and a condensation collection outlet, the condensation collection inlet being coupled to the air intake system and the condensation collection outlet being coupled to the input port of the condensation accumulator;

a condensation expulsion line being coupled to the outlet port of the condensation accumulator and being disposed in fluid communication with the atmosphere; and

a condensation control valve being disposed between the air intake system and the condensation collection inlet of the condensation collection line, the condensation control valve having an open position allowing condensation to enter the condensation collection line from the air intake system and the condensation control valve having a closed position preventing condensation from entering the condensation collection line.

16. The internal combustion engine of claim 15 further comprising at least one filter, the at least one filter being disposed in at least one of the condensation collection line and the condensation expulsion line.

17. The internal combustion engine of claim 15 , wherein at least a portion of the condensation expulsion line being disposed in contact with the exhaust pipe.
