Engine Displacement Formula:
| From: | To: |
Engine displacement refers to the total volume of all the cylinders in an engine. It's a key measurement that indicates the engine's size and power potential, typically measured in cubic inches or liters.
The calculator uses the engine displacement formula:
Where:
Explanation: The formula calculates the volume of a single cylinder (bore area × stroke) and multiplies by the number of cylinders to get total displacement.
Details: Engine displacement is a primary factor in determining an engine's power output, torque characteristics, and fuel consumption. Larger displacements generally produce more power but consume more fuel.
Tips: Enter bore and stroke measurements in inches, and the number of cylinders. All values must be positive numbers with bore and stroke greater than zero, and at least one cylinder.
Q1: What's the difference between cubic inches and liters?
A: Cubic inches and liters are both units of volume. 1 liter equals approximately 61.02 cubic inches. Most modern engines use liter measurements.
Q2: How does displacement relate to engine power?
A: Generally, larger displacement engines can produce more power, but efficiency, design, and technology also significantly impact actual power output.
Q3: Can I use this calculator for metric measurements?
A: This calculator is designed for imperial measurements (inches). For metric, convert centimeters to inches first or use a different formula.
Q4: What is a typical displacement range for car engines?
A: Modern car engines typically range from about 1.0L (61 cubic inches) to 6.0L (366 cubic inches) or more for performance vehicles.
Q5: Why is the constant 0.7854 used in the formula?
A: This constant represents π/4, which is used to calculate the area of a circle from its diameter (bore = diameter).
