Engine 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 power potential, measured in cubic centimeters (cc) or liters.
The calculator uses the engine displacement formula:
Where:
Explanation: The formula calculates the volume of a single cylinder (πr² × stroke) and multiplies it by the number of cylinders to get total displacement, then converts to cubic centimeters.
Details: Engine displacement is a critical factor in determining engine performance, fuel efficiency, emissions, and vehicle classification. 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. The result will be displayed in cubic centimeters (cc).
Q1: Why is engine displacement measured in cc?
A: Cubic centimeters provide a precise measurement of engine volume that's widely used in automotive specifications worldwide, especially for smaller engines.
Q2: How does displacement relate to engine power?
A: Generally, larger displacement engines can produce more power, but actual power output also depends on factors like engine design, compression ratio, and forced induction.
Q3: What's the difference between bore and stroke?
A: Bore is the diameter of the cylinder, while stroke is the distance the piston travels from top to bottom. Both dimensions affect displacement and engine characteristics.
Q4: Can I use inches instead of millimeters?
A: Yes, but you'll need to convert to the same units throughout the calculation or adjust the formula accordingly for consistent results.
Q5: Why divide by 1000 in the calculation?
A: The division by 1000 converts cubic millimeters to cubic centimeters, as 1 cc = 1000 mm³.
