🔍 Key Concepts

• Compression ratio definition and what volumes it compares • Relationship between swept volume, clearance volume, and total cylinder volume • Setting up an equation using the given compression ratio and swept volume to solve for clearance volume

💭 Think About

• What two volumes are being compared when we say the compression ratio is 13.5:1? Which one is larger? • How can you write an equation that uses: total volume at bottom dead center = swept volume + clearance volume? • Once you write the compression ratio as a fraction using those volumes, how can you solve that equation for the unknown clearance volume?

✅ Before You Answer

• Be sure you are using total volume at bottom dead center divided by volume at top dead center for the compression ratio, not the other way around • Confirm that swept volume + clearance volume equals the bigger volume in the ratio • After solving, check that the result is a realistic small volume compared to 125 cubic inches and matches one of the choices
