Cubic Inches Formula:
| From: | To: |
Engine cubic inches calculation determines the total volume displaced by all pistons in an internal combustion engine. It's a key measurement of engine size and potential power output, commonly used in automotive applications.
The calculator uses the engine displacement formula:
Where:
Explanation: The formula calculates the volume of a single cylinder (π × radius² × height) and multiplies by the number of cylinders. Since bore is diameter, we use B_e²/4 to get the area.
Details: Engine displacement is a primary factor in determining engine power, 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 cylinders between 1-16.
Q1: What's the difference between cubic inches and liters?
A: Cubic inches and liters are both measurements of volume. 1 liter equals approximately 61.02 cubic inches. Many modern engines are measured in liters.
Q2: How does displacement relate to engine power?
A: Generally, larger displacement engines can produce more power, but efficiency, forced induction, and technology can allow smaller engines to outperform larger ones.
Q3: What are typical values for bore and stroke?
A: Bore typically ranges from 3-4.5 inches, stroke from 3-4.5 inches in passenger vehicles. Performance engines often have larger bore relative to stroke.
Q4: Can I use this for metric measurements?
A: This calculator uses inches. For metric, convert to cubic centimeters (cc) by using centimeters instead of inches and removing the /4 factor.
Q5: Why is displacement important for car classification?
A: Many racing series and regulations classify vehicles by engine displacement, as it's a standardized measure of engine size.
