🔍 Key Concepts

• Relationship between camshaft and crankshaft speed in a four-stroke engine • How many crankshaft revolutions are required for one full four-stroke cycle (intake, compression, power, exhaust) • Ratio of camshaft speed to crankshaft speed (gear or chain drive)

💭 Think About

• In a four-stroke engine, think about how many times the camshaft must open and close the valves for every full cycle of the piston. • If the camshaft is gear-driven from the crankshaft, should the camshaft turn faster or slower than the crankshaft in a four-stroke engine? By what factor? • If you know the speed ratio between the camshaft and crankshaft, how do you calculate the crankshaft speed when the camshaft speed is known?

✅ Before You Answer

• Recall that in a four-stroke engine, the piston needs two full crankshaft revolutions to complete one cycle. • Verify whether the camshaft completes one revolution per full engine cycle or more than one. • Use the correct speed ratio (camshaft : crankshaft) to multiply or divide the given 750 rpm before picking an answer.
