Basic

Engine Displacement

Total swept volume of all cylinders.

Formula

V = \frac{\pi}{4} b^2 s\, n

Variables

VDisplacement (cc)

bBore (cm)

sStroke (cm)

nCylinders

Example

b=8.6, s=8.6, n=4: V ≈ 1998 cc (2.0 L)

Did You Know?

A 'square' engine has equal bore and stroke, balancing high-rev breathing against low-end torque.
