1. What is Engine Displacement?

Engine displacement is the total volume of all the cylinders in an internal combustion engine. It's a key specification that indicates 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:

• \( V \) — Engine displacement (cc)
• \( bore \) — Diameter of each cylinder (mm)
• \( stroke \) — Distance piston travels in cylinder (mm)
• \( cylinders \) — Number of cylinders in the engine

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 Displacement Calculation

Details: Displacement affects engine power, torque, fuel efficiency, and emissions. It's used for engine classification, performance tuning, and regulatory purposes.

4. Using the Calculator

Tips: Enter bore and stroke in millimeters, and number of cylinders. All values must be positive numbers (bore > 0, stroke > 0, cylinders ≥ 1).

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.

Q2: How does displacement relate to engine power?
A: Generally, larger displacement means more potential power, but actual power depends on many factors including engine design and forced induction.

Q3: What's a typical displacement range?
A: Motorcycles: 50-2000cc, Cars: 1000-8000cc, Trucks: 4000-16000cc. Modern passenger cars are typically 1000-3000cc.

Q4: How do I convert cc to liters?
A: Divide by 1000 (e.g., 2000cc = 2.0L). Many countries use cc for smaller engines and liters for larger ones.

Q5: What's the difference between displacement and compression ratio?
A: Displacement is total cylinder volume, while compression ratio is the ratio of maximum to minimum cylinder volume during piston stroke.
