1. What is Engine Displacement?

Engine displacement is the total volume of air/fuel mixture an engine can draw in during one complete engine cycle. It's a key indicator of engine size and power potential, typically measured in cubic centimeters (cc) or liters (L).

2. How Does the Calculator Work?

The calculator uses the engine displacement formula:

Where:

• \( D \) — Engine displacement (cc)
• \( b \) — Bore diameter (mm)
• \( s \) — Stroke length (mm)
• \( n \) — Number of cylinders
• \( \pi \) — Mathematical constant (approximately 3.14159)

Explanation: The formula calculates the volume of a single cylinder (πr² × stroke) and multiplies by the number of cylinders, then converts from mm³ to cc by dividing by 1000.

3. Importance of Engine Displacement

Details: Engine displacement directly relates to engine power output, fuel consumption, and vehicle performance characteristics. Larger displacements generally produce more power but consume more fuel.

4. Using the Calculator

Tips: Enter bore and stroke measurements in millimeters, and the number of cylinders. All values must be positive numbers. The calculator will compute the total engine displacement in cubic centimeters.

5. Frequently Asked Questions (FAQ)

Q1: 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 dead center.

Q2: How does displacement affect engine performance?
A: Larger displacement engines typically produce more torque and horsepower, but may have lower fuel efficiency compared to smaller engines.

Q3: What is a typical displacement range for cars?
A: Modern passenger cars range from about 1000cc to 6000cc, with most falling between 1500cc and 3000cc.

Q4: Can I calculate displacement in liters instead of cc?
A: Yes, 1000cc = 1 liter. You can divide the cc result by 1000 to get liters.

Q5: Why divide by 1000 in the formula?
A: The division converts the result from cubic millimeters to cubic centimeters (1 cm³ = 1000 mm³).
