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 the engine's 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 (mm³, converted to 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 it by the number of cylinders to get total displacement.

3. Importance of Engine Displacement

Details: Displacement is directly related to an engine's power output and fuel consumption. Larger displacement engines typically 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 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 power, but engine design, forced induction, and other factors also affect power output.

Q3: What's a typical displacement for different vehicles?
A: Motorcycles: 125-1800cc, Cars: 1000-8000cc, Trucks: 4000-16000cc.

Q4: What is the compression ratio?
A: The ratio of the cylinder's maximum to minimum volume, different from displacement which is the total swept volume.

Q5: Why convert from mm³ to cc?
A: Engine displacement is traditionally measured in cubic centimeters (cc) or liters (1L = 1000cc), making it easier to compare engine sizes.
