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, or cubic inches.

2. How Does the Calculator Work?

The calculator uses the engine displacement formula:

Where:

• \( Bore \) — Diameter of each cylinder (millimeters)
• \( Stroke \) — Distance the piston travels (millimeters)
• \( Cylinders \) — Number of cylinders in the engine
• \( \pi \) — Mathematical constant (approximately 3.1416)

Explanation: The formula calculates the volume of a single cylinder (πr²h) and multiplies by the number of cylinders to get total 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 in millimeters, and the number of cylinders. All values must be valid positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between cc and liters?
A: 1000cc equals 1 liter. Engine sizes are often expressed in liters for automotive applications.

Q2: How does bore/stroke ratio affect engine performance?
A: Engines with larger bore relative to stroke (oversquare) tend to rev higher, while engines with longer stroke relative to bore (undersquare) produce more torque at lower RPMs.

Q3: Why is displacement important for vehicle classification?
A: Many countries use engine displacement to determine vehicle tax brackets, insurance rates, and license requirements.

Q4: Can I convert cc to horsepower?
A: Not directly. Horsepower depends on many factors beyond displacement, including engine design, fuel system, and forced induction.

Q5: What's a typical displacement range for different vehicles?
A: Motorcycles: 50-2000cc, Cars: 1000-8000cc, Trucks: 4000-16000cc. These are general ranges with many exceptions.
