🔍 Key Concepts

• Basic four-stroke diesel or gasoline engine operation (intake, compression, power, exhaust) • Difference between a stroke, a revolution (rotation), and a full cycle in an internal combustion engine • How many crankshaft rotations occur in a full four-stroke cycle

💭 Think About

• Think about what specific set of events must happen before the same event (like a power stroke) repeats itself. • Ask yourself: does a single crankshaft rotation include all four events (intake, compression, power, exhaust) in a four-stroke engine? • Consider whether one piston stroke (up or down) is enough to complete all the events needed to generate a power pulse.

✅ Before You Answer

• Be clear on the difference between stroke (up or down movement of piston) and revolution (full 360° turn of crankshaft). • Confirm what engineers and mechanics mean when they say a "four-stroke cycle" engine. • Verify whether a cycle is tied to the repetition of the power event, or just any single movement or rotation.
