A square engine (equal bore and stroke) of 86mm × 86mm with 4 cylinders displaces approximately 2.0 liters.

Frequently asked questions

How is engine displacement calculated?
Displacement (cc) = (π/4) × bore² × stroke × cylinders ÷ 1,000. This gives the swept volume of all pistons combined in cubic centimeters.
What does engine displacement affect?
Larger displacement generally means more potential power and torque, but also higher fuel consumption. Forced induction (turbo/supercharger) lets smaller engines produce more power.
