🔍 Key Concepts

• Valve spring compression in relation to camshaft lobe position and valve lift • How a compression spring behaves as it is compressed further (Hooke’s Law concept) • Relationship between valve lift (amount the valve is pushed open) and spring load

💭 Think About

• As the cam pushes the valve open, what happens to the distance between the valve spring’s ends? Does it get shorter or longer? • When the valve is fully seated (closed), is the spring at its minimum, medium, or maximum compression compared to when the valve is opening? • Think about a typical compression spring: at which point in its travel does it store the most force—near free length or when most compressed?

✅ Before You Answer

• Visualize the cam lobe position for seated, partially open, and fully open valve and how far the spring is compressed in each case • Recall that spring load increases with compression: more compression = higher force • Make sure you distinguish between valve position (seated vs open) and spring deflection (how much shorter the spring is than its free length)
