Engine airflow adjustment system
An engine airflow adjustment system that includes an engine that powers operation of a vehicle. A fan drives an airflow over the engine to convectively cool the engine. A funnel receives a portion of the airflow from the fan and directs the airflow to a specific location on the engine to blow debris off of the engine.
1. An engine airflow adjustment system, comprising:
an engine configured to power operation of a vehicle;
a fan configured to drive an airflow over the engine to convectively cool the engine; and
a funnel configured to receive a portion of the airflow from the fan and direct the airflow to a specific location on the engine to blow debris off of the engine, the funnel comprising a front wall configured to direct the airflow from the fan towards the engine, wherein:
the front wall comprises a first front wall portion and a second front wall portion, and wherein the first front wall portion is angled relative to the top wall and the second front wall portion is angled relative to the first front wall portion, and
the front wall defines an aperture, the aperture extends between the first front wall portion and the second front wall portion, and wherein the aperture is configured to redirect debris entering the funnel.
2. The system of claim 1 , comprising a frame surrounding the engine, wherein the funnel is configured to couple to the frame.
3. The system of claim 1 , wherein the funnel comprises a first sidewall and a second sidewall separated from each other by a gap.
4. The system of claim 3 , wherein the first sidewall comprises a first sidewall portion and a second sidewall portion, and the second sidewall comprises a third sidewall portion and a fourth sidewall portion.
5. The system of claim 4 , wherein the first sidewall portion and the third sidewall portion are substantially parallel to each other.
6. The system of claim 5 , wherein the second sidewall portion and the fourth sidewall portion are angled relative to the respective first sidewall portion and the third sidewall portion, and wherein the second sidewall portion and fourth sidewall portion are configured to funnel airflow from the fan into the gap formed by the first sidewall portion and the third sidewall portion.
7. The system of claim 1 , wherein an angle formed by the first front wall portion and the second front wall portion is between 10-60 degrees.
8. An engine airflow adjustment system, comprising:
a funnel configured to receive a portion of an airflow from a fan and redirect the airflow to a specific location on an engine to blow debris off of the engine, the funnel comprises:
a first sidewall, the first sidewall comprises:
a first sidewall portion and a second sidewall portion, wherein the first sidewall portion is angled relative to the second sidewall portion;
a second sidewall separated from the first sidewall by a gap, the second sidewall comprises:
a third sidewall portion and a fourth sidewall portion, wherein the third sidewall portion is angled relative to the fourth sidewall portion;
a top wall coupled to the first sidewall and the second sidewall; and
a front wall coupled to the first sidewall and the second sidewall and configured to redirect the airflow from the fan towards the engine, the front wall comprising a first front wall portion and a second front wall portion, and wherein:
the first front wall portion is angled relative to the top wall and the second front wall portion is angled relative to the first front wall portion, and
the front wall defines an aperture, and wherein the aperture extends between the first front wall portion and the second sidewall portion.
9. The system of claim 8 , wherein the first sidewall portion and the third sidewall portion are substantially parallel to each other.
10. The system of claim 8 , wherein an angle formed by the first front wall portion and the second front wall portion is between 10-60 degrees.
11. An engine airflow adjustment system, comprising:
a funnel configured to receive a portion of an airflow from a fan and redirect the airflow to a specific location on an engine to blow debris off of the engine, the funnel comprises:
a top wall;
a first sidewall coupled to the top wall;
a second sidewall coupled to the top wall and separated from the first sidewall by a gap;
a front wall coupled to the first sidewall and the second sidewall and configured to direct the airflow from the fan towards the engine, the front wall comprises:
a first front wall portion, wherein the first front wall portion is angled relative to the top wall; and
a second front wall portion, wherein the second front wall portion is angled relative to the first front wall portion,
wherein the front wall defines an aperture, and wherein the aperture extends between the first front wall portion and the second front wall portion.
12. The system of claim 11 , wherein an angle formed by the first front wall portion and the second front wall portion is between 10-60 degrees.
13. The system of claim 11 , wherein the first sidewall comprises a first sidewall portion and a second sidewall portion, and wherein the first sidewall portion is angled relative to the second sidewall portion.
14. The system of claim 11 , wherein the second sidewall comprises a third sidewall portion and a fourth sidewall portion, and wherein the third sidewall portion is angled relative to the fourth sidewall portion.
