1. What is the Displacement Formula?

The displacement formula calculates the total volume displaced by all pistons in an internal combustion engine. It represents the engine's size and is a key indicator of its power potential.

2. How Does the Calculator Work?

The calculator uses the displacement formula:

\[ Disp\_cc = \pi \times (B\_mm/2)^2 \times S\_mm \times Cyl \]

Where:

\( \pi \) — Mathematical constant (approximately 3.14159)
\( B\_mm \) — Bore diameter in millimeters
\( S\_mm \) — Stroke length in millimeters
\( Cyl \) — 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 displacement.

3. Importance of Displacement Calculation

Details: Engine displacement is crucial for understanding engine performance characteristics, fuel consumption, emissions, and vehicle classification. Larger displacement generally means more power but also higher fuel consumption.

4. Using the Calculator

Tips: Enter bore and stroke measurements 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: Why is displacement measured in cubic centimeters?
A: Cubic centimeters (cc) provide a convenient metric unit for engine size. 1000 cc equals 1 liter, which is commonly used for larger engines.

Q2: How does displacement relate to engine power?
A: Generally, larger displacement engines can produce more power, but actual power output also depends on factors like compression ratio, fuel system, and engine design.

Q3: 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. Both dimensions affect the engine's displacement and characteristics.

Q4: Can I use inches instead of millimeters?
A: Yes, but you'll need to convert the result appropriately. The formula works with any consistent units, though millimeters are standard for metric calculations.

Q5: Why multiply by the number of cylinders?
A: The formula calculates displacement for one cylinder, so multiplying by the total number of cylinders gives the engine's total displacement.
