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), liters (L), or cubic inches (ci).

2. How Does the Calculator Work?

The calculator uses the engine displacement formula:

Where:

• \( CC \) — Engine displacement in cubic centimeters
• \( \pi \) — Mathematical constant (approximately 3.14159)
• \( B \) — Bore diameter in millimeters
• \( S \) — Stroke length in millimeters
• \( N \) — Number of cylinders

Explanation: The formula calculates the volume of a single cylinder (πr²h) 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 displacement engines typically 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 each cylinder, while stroke is the distance the piston travels inside the cylinder.

Q2: How does engine displacement affect performance?
A: Generally, larger displacement engines produce more torque and power, but other factors like compression ratio and engine design also play important roles.

Q3: Can I convert CC to liters?
A: Yes, 1000cc equals 1 liter. Many manufacturers list engine sizes in liters (e.g., 2.0L).

Q4: What is a typical displacement range for cars?
A: Modern passenger cars typically range from about 1000cc to 5000cc, with most falling between 1500cc and 2500cc.

Q5: Does displacement affect fuel economy?
A: Generally yes - larger displacement engines tend to consume more fuel, though modern technologies like turbocharging and cylinder deactivation can mitigate this relationship.
