As the camshaft turns, the lobes open and close the intake valves and exhaust valves in time with the movement of the piston. The key elements of any camshaft are the lobes. And then we’ll review some of the interesting ways that some cars adjust the camshaft so that it can handle various engine more efficiently. We have some great animations that show you how different engine models, such as single overhead cam (SOHC) and dual overhead camshaft (DOHC), really work. In this article you will learn how the camshaft affects engine performance. On the next page of this article, you can see the animation, we have built to really show you the difference between a camshaft and a performance standard.

This is a critical work, and can have a big impact on engine performance at different speeds. The camshaft (called party uses cam lobes) which push against the valves open as the camshaft rotates springs on the valves return them to their closed position. If you read the article How Car Engines Work, you know about the valves that allow air / fuel into the engine and exhaust on the engine.
