Engine Displacement Calculator

Engine displacement (d):

Bore (b):

Stroke length (s):

Number of cylinders (N) :

How This Is Calculated

$$ D = \pi \cdot \left(\frac{b}{2}\right)^2 \cdot s \cdot N $$ where:

D = Engine displacement (m)

b = Bore (m)

s = Stroke length (m)

N = Number of cylinders (Dimensionless)

Assumptions

Piston motion is ideal.
Combustion volume remains constant.
The engine is four stroke.
Dead volume is neglected.
