In an effort to simplify what actually happens inside a 4-stroke internal combustion engine, we invite you to “take a walk” inside a typical engine.

We will discuss valve events, piston position, overlap and centerlines. Although we do not have enough room to explain cam design in detail, we will clear up several of the most often misunderstood terms. We hope to give you a more clear understanding of what actually occurs in the operation of a four-stroke engine. We will graphically illustrate the relationship between all parts of the engine and to try to help you understand how the camshaft affects the power of the engine.
