Displacement Formula:
| From: | To: |
Engine displacement refers to the total volume of all the cylinders in an internal combustion engine. It's a key specification that indicates the engine's size and potential power output, typically measured in cubic centimeters (cc) or liters.
The calculator uses the displacement formula:
Where:
Explanation: The formula calculates the volume of a single cylinder (πr² × stroke) and multiplies by the number of cylinders, then converts from cubic millimeters to cubic centimeters.
Details: Engine displacement is a critical factor in determining engine performance, fuel efficiency, and emissions. Larger displacements generally produce more power but may consume more fuel.
Tips: Enter bore and stroke measurements in millimeters, and the number of cylinders. All values must be positive numbers with bore and stroke greater than zero.
Q1: What's the difference between cc and liters?
A: 1000 cc equals 1 liter. Engine displacement is often expressed in liters for automotive applications.
Q2: How does displacement relate to engine power?
A: Generally, larger displacement engines can produce more power, but technology like turbocharging can allow smaller engines to produce similar power.
Q3: Why are bore and stroke important?
A: The bore/stroke ratio affects engine characteristics - oversquare engines (bore > stroke) tend to rev higher, while undersquare engines have better low-end torque.
Q4: Can I use this calculator for any engine type?
A: This formula works for most piston engines, including inline, V, flat, and rotary engines (with appropriate cylinder count).
Q5: How accurate is this calculation?
A: This provides theoretical displacement. Actual displacement may vary slightly due to manufacturing tolerances and combustion chamber design.
