| Where | D equals bore in inches |
| S equals stroke in inches | |
| Where N equals number of cylinders |
| Example: | Required to find the piston displacement of a 31⁄2 × 5 inch four-cylindered motor. D equals 3.5 S equals 5. and N equals 4. |
Piston Displacement
3.52 times 5 times 4 times 3.14 4
3.5 times 3.5 times 5 times 4 times 3.14 4
equals 173.58 cubic inches.
