🔍 Key Concepts

• Formula for compression ratio in a reciprocating engine • Difference between swept volume and clearance volume • How to correctly form the ratio using total volume at bottom dead center and volume at top dead center

💭 Think About

• First, express the total volume in the cylinder when the piston is at bottom dead center (BDC). How do you get that from the given numbers? • Then, express the volume when the piston is at top dead center (TDC). Which of the given volumes corresponds to this? • Finally, set up the compression ratio as a fraction using these two volumes and simplify it to match one of the answer choices.

✅ Before You Answer

• Be sure you are using (swept volume + clearance volume) in the numerator of the ratio, not just one of them. • Confirm that the denominator of the compression ratio uses only the clearance volume at top dead center. • After calculating the numerical ratio, round to the nearest tenth to compare it with the multiple-choice options.
