Air flow guide for an internal combustion engine

1. An air diverter for an internal combustion engine comprising:

a main diverter shield having a proximal end extending from a cooling source to a distal end extending to a back end of the internal combustion engine;

a first arcuate member attached to the main diverter shield between the proximal end and the distal end of the main diverter shield having an arc extending perpendicular to the main diverter shield toward an interior of the internal combustion engine; and

a second arcuate member connected to the main diverter shield near the distal end of the main diverter shield.

2. The air diverter of claim 1 wherein the air diverter is attached to a single cylinder of a multi-cylinder engine.

3. The air diverter of claim 1 wherein the first arcuate member has a width less than that of the second arcuate member.

4. The air diverter of claim 1 wherein the first arcuate member directs airflow generally to a center of a cylinder head.

5. The air diverter of claim 4 wherein the airflow is directed across push rod tubes enclosing push rods of the internal combustion engine.

6. The air diverter of claim 5 wherein the push rod tubes extend entirely within a cylinder head of the internal combustion engine.

7. The air diverter of claim 1 wherein the second arcuate member directs airflow across rear air cooling fins of a cylinder head of the internal combustion engine.

8. The air diverter of claim 1 wherein the second arcuate member is constructed integrally with the main diverter shield.

9. The air diverter of claim 1 wherein the first arcuate member is an independent member and fastened to the main diverter shield and the main diverter shield is fastened to a cylinder head of the internal combustion engine with at least one fastener.

10. The air diverter of claim 1 wherein the first arcuate member is arranged on the air diverter to form three air flow paths, a first and third air flow path directs air to the second arcuate member and a second air flow path directs air toward a centralized area of a cylinder head of the internal combustion engine.

11. An air cooled internal combustion engine comprising:

a block having at least one cylinder;

a cylinder head connected to the block and having a plurality of cooling fins arranged about a periphery of the cylinder head; and

an air diverter attached to the cylinder head and comprising first and second arcuate members constructed to direct air flow to separate areas of the cylinder head; and

wherein the first arcuate member is arranged on the air diverter to form three air flow paths; and

wherein a first and third air flow path directs air to the second arcuate member and a second air flow path directs air toward a centralized area of the cylinder head.

12. The air cooled internal combustion engine of claim 11 wherein the air diverter has first and second air diversion channels, the first air diversion channel arranged to divert cooling air toward a center of the cylinder head and the second air diversion channel arranged to direct air to rear cooling fins of the cylinder head.

13. The air cooled internal combustion engine of claim 11 wherein the first arcuate member has a width less than that of the second arcuate member.

14. The air cooled internal combustion engine of claim 11 incorporated in a wheel driven vehicle.

15. The air cooled internal combustion engine of claim 11 incorporated in a non-wheel driven apparatus.
