Piston Engines  Displacement
Calculate piston engine displacement.
The displacement of a piston engine can be calculated as
V = (π / 4) s b^{2} no_{c} (1)
where
V = engine displacement (in^{3}, cm^{3})
s = stroke (in, cm)
b = bore diameter (in, cm)
no_{c} = number of cylinders
Example  Displacement of V8 Engine
The displacement of a 8 cylinder piston engine with stroke 3.31 in and bore 3.625 in can be calculated as
V = (π / 4) (3.31 in) (3.625 in)^{2} (8)
= 273 cu in
