1. What is Engine Displacement?

Engine displacement, also known as engine capacity, is the total volume of air/fuel mixture an engine can draw in during one complete engine cycle. It's typically measured in cubic centimeters (cc) or liters (L).

2. How Does the Calculator Work?

The calculator uses the engine displacement formula:

Where:

• \( B \) — Bore diameter (millimeters)
• \( S \) — Stroke length (millimeters)
• \( N \) — Number of cylinders
• \( \pi \) — Mathematical constant (approximately 3.14159)

Explanation: The formula calculates the volume of a single cylinder (πr² × height) and multiplies it by the number of cylinders to get total engine displacement.

3. Importance of Engine Displacement

Details: Engine displacement is a key indicator of an engine's power potential and fuel consumption. 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.

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 within the cylinder.

Q2: How does displacement relate to engine power?
A: Generally, larger displacement engines can produce more power, but efficiency, technology, and design also play significant roles.

Q3: What is a typical displacement range for cars?
A: Most passenger cars have displacements between 1000-3000cc, with performance vehicles often exceeding this range.

Q4: How do I convert cc to liters?
A: Divide the cc value by 1000. For example, 2000cc equals 2.0 liters.

Q5: Does larger displacement always mean better performance?
A: Not necessarily. Engine design, forced induction, and efficiency technologies can allow smaller engines to outperform larger ones.
