Piston Displacement Calculator

1. What is Piston Displacement?

Definition: Piston displacement is the volume swept by the piston in a cylinder, calculated using the formula:

\[ V = \frac{\pi}{4} \times B^2 \times S \]

Variables:

  • \( V \): Displacement volume (e.g., in³, cm³, L).
  • \( B \): Bore (diameter of the cylinder, in inches).
  • \( S \): Stroke (length of piston travel, in inches).
Explanation: This formula calculates the volume displaced by the piston as it moves from bottom dead center to top dead center.

2. Importance of Piston Displacement Calculation

Details: This calculation is crucial for engine design, determining engine capacity, and optimizing performance in internal combustion engines.

3. Using the Calculator

Tips: Enter the bore and stroke values with their respective units. Click "Calculate" to get the displacement in multiple units.
