1. What is the CSG Engine Displacement Formula?

The CSG (Cylinder Swept Volume × Number of Cylinders) formula calculates the total displacement of an internal combustion engine. It represents the total volume swept by all the pistons during one complete engine cycle.

2. How Does the Calculator Work?

The calculator uses the CSG displacement formula:

\[ Disp_{csg} = \pi \times \left(\frac{B}{2}\right)^2 \times S \times Cyl \]

Where:

\( B \) — Bore diameter (mm)
\( S \) — Stroke length (mm)
\( Cyl \) — Number of cylinders
\( \pi \) — Mathematical constant (approximately 3.1416)

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 Calculation

Details: Engine displacement is a key specification that indicates engine size and potential power output. It's used for vehicle classification, performance comparisons, and technical specifications.

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: Why is engine displacement measured in cubic centimeters?
A: Cubic centimeters (cc) is the standard unit for engine displacement as it provides a convenient measurement scale for typical engine sizes.

Q2: How does displacement relate to engine power?
A: Generally, larger displacement engines can produce more power, but many other factors like compression ratio, forced induction, and engine design also affect power output.

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 from top to bottom dead center.

Q4: Can this formula be used for any engine type?
A: This formula works for most piston engines including inline, V, flat, and rotary engines (with appropriate modifications for rotary engine geometry).

Q5: How accurate is this calculation?
A: The calculation provides theoretical displacement. Actual working displacement may vary slightly due to manufacturing tolerances and combustion chamber design.
