Engine Displacement: 86mm Bore × 86mm Stroke, 4 Cylinders
An engine with an 86mm bore, 86mm stroke, and 4 cylinders has a displacement of approximately 2.0 liters.
How to use this tool
- Enter the cylinder bore diameter in millimeters.
- Enter the piston stroke length in millimeters.
- Enter the number of cylinders.
- The calculator returns displacement in cc and liters.
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.
