Engine Displacement Calculator

Example Calculations

Example 1:

• Bore Diameter (D): 80 mm
• Stroke Length (S): 90 mm
• Number of Cylinders (N): 4

Calculation:

$ED = \frac{\pi}{4} \times 80^2 \times 90 \times 4 = \frac{3.14159}{4} \times 6400 \times 90 \times 4 \approx 1809557 \text{ cc}$

Example 2:

• Bore Diameter (D): 85 mm
• Stroke Length (S): 88 mm
• Number of Cylinders (N): 6

Calculation:

$ED = \frac{\pi}{4} \times 85^2 \times 88 \times 6 = \frac{3.14159}{4} \times 7225 \times 88 \times 6 \approx 2994618 \text{ cc}$
