An engine with a 79mm bore, 81mm stroke, and 4 cylinders has a displacement of approximately 1.6 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 common compact car engine specification of 79mm bore and 81mm stroke across 4 cylinders displaces about 1.6 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.
