Engine displacement is the volume, measured as the space between the top of the piston at bottom dead center (BDC) and top of the cylinder.
This chart describes the engine displacement based on Bore and Stroke.
- Bore is the diameter of the engine cylinder.
- Stroke length is the distance travelled by the piston during each cycle of the engine.
- Stroke is affected by the swing of crankshaft during a rotation and the connecting rod length.
The combustion chamber is in the head and is not part of this calculation.
