Camshaft
|
| |
|
| What happened: |
The lobes on the camshaft taken from engine B had the majority of the coating removed and had a dull and rougher finish. The lobes on the camshaft taken from engine A, with the exception of the point of the lobes, still had the original coating, plus, there is visible protection provided by the anti-wear elements of the motor oil |
| |
|
| Why did it happen: |
The camshaft is the most heavily loaded component in the engine and one of the primary causes of wear on camshaft lobes is lack or inadequate lubrication. |
| |
|
| Why is this important: |
Mild camshaft wear the valve will not open as far as it should resulting in a loss of torque. More severe wear to the camshaft will cause a significant loss in torque and may cause the engine to misfire. |
| |
|
| Vehicle application: |
This is equally important for automotive, truck and racing. The camshaft controls the opening and closing of the valves in each cylinder. For an engine to operate efficiently and at its maximum performance, the valves must be able to open and close at the appropriate time. |
