🔍 Key Concepts

• 4-stroke engine cycle: intake, compression, power, exhaust • Meaning of top dead center (TDC) and what happens right at that instant • Relationship between ignition, combustion, and the start of the power stroke

💭 Think About

• At the TDC between the compression and power strokes, which processes are happening or just about to happen? • Which of the listed events belongs to a different stroke than the one associated with compression → power? • Think about the exact moment the piston stops rising and is about to move down: which events are directly tied to that transition?

✅ Before You Answer

• Identify which stroke the piston is on when it reaches TDC just before the power stroke. • Match each option (intake, ignition, power, combustion) to its primary stroke in a 4-stroke cycle. • Verify which event occurs over a period of crank rotation (not just at an instant) versus which belongs clearly to another part of the cycle.
